BOOM! Mobile Launches T-Mobile Plans

The mobile virtual network operator BOOM! Mobile recently launched wireless plans that run over T-Mobile’s network. With this addition, BOOM! now offers three types of plans:

  • Boom! Red – service over Verizon’s network
  • Boom! Blue – service over AT&T’s network
  • Boom! Pink – service over T-Mobile’s network

Many of the Boom! Pink plans have the same allotments of minutes, texts, and data as well as the same price points as previously existing Boom! Red plans. Boom! Blue plans with allotments equivalent to those in Pink and Red plans are sometimes available, but they tend to have higher price points.

BOOM! Mobile is also offering several Boom! Pink plans that are unlike the company’s previous offerings. These plans each offer a certain number of Flex Points. Each point can be redeemed for either 1 minute of calling, 1 text message, or 1MB of data.

  • 450 Flex Points (7 Day Plan) – $5
  • 900 Flex Points (14 Day Plan) – $10
  • 3,000 Flex Points (Yearly Plan) – $60

My thoughts

It’s great to see BOOM! Mobile expanding its offerings. For most consumers, I think the Red plans will continue to be the best option since (a) they aren’t more expensive than the Pink plans and (b) they run over Verizon’s extensive network. I expect most consumers looking for coverage over T-Mobile’s could find better deals with an alternative MVNO (e.g., Mint Mobile). Still, I’m glad to see BOOM! Mobile offering access to more networks. The new flex plans are particularly interesting. I’d love to see more carriers come out with plans that use similar structures.

NYT Story On Location Tracking

The New York Times is running a series of articles on cell phone location tracking. The Times received access to a database with location data from about 12 million devices. In the series, reporters explain how easy it is to de-anonymize the allegedly anonymous location data. Here’s an excerpt from the first article:

Dozens of companies — largely unregulated, little scrutinized — are logging the movements of tens of millions of people with mobile phones and storing the information in gigantic data files. The Times Privacy Project obtained one such file, by far the largest and most sensitive ever to be reviewed by journalists. It holds more than 50 billion location pings from the phones of more than 12 million Americans…The data reviewed by Times Opinion didn’t come from a telecom or giant tech company, nor did it come from a governmental surveillance operation. It originated from a location data company, one of dozens quietly collecting precise movements using software slipped onto mobile phone apps. You’ve probably never heard of most of the companies — and yet to anyone who has access to this data, your life is an open book. They can see the places you go every moment of the day, whom you meet with or spend the night with, where you pray, whether you visit a methadone clinic, a psychiatrist’s office or a massage parlor…Yes, the location data contains billions of data points with no identifiable information like names or email addresses. But it’s child’s play to connect real names to the dots that appear on the maps.

I have quibbles with the articles, but I strongly recommend them. It looks like the Times is currently four articles into what will be a seven-article series.

US Mobile’s New Unlimited Plans – Well-Priced With Some Limits & Hidden Fees

The carrier US Mobile recently released new unlimited plans. As with US Mobile’s old plans, customers can choose either the Super LTE network or the GSM LTE network. Super LTE runs over Verizon’s network while GSM LTE runs over T-Mobile’s network. Plans appear to be priced the same regardless of the network a subscriber chooses.1

“Unlimited” is a bit of a misnomer for US Mobile’s new plans. The plans have limits, but the limits are dependent on which options subscribers select. Customers can choose either US Mobile’s “Fast” plan or its “Ludicrous” plan.

Limits

As I understand them, here are the limits on the Fast plan (base price of $40 per month):

  • Speeds are usually throttled to a maximum of 5Mbps
  • If 50GB of data is used in a single month, speeds are throttled intensely (15GB with GSM)
  • Hotspot use is not permitted (can be added for an additional $5 per month)

The Ludicrous plan has a base price of $50 per month. The Ludicrous plan does not have a 5Mbps throttle, and mobile hotspot is included. As with the Fast plan, data use beyond 50GB (15GB with GSM) is throttled intensely.

I use the phrase “throttled intensely” because US Mobile doesn’t disclose its policies clearly. On its website, the company writes:

Super LTE plans come with 50GB of high-speed data. A tiny fraction of heavier data users may notice reduced speeds afterwards.
While I appreciate the disclosure, I think there’s a lot wrong with it. While I interpreted it as indicating that speeds would be throttled intensely, a Reddit user thought the disclosure implied US Mobile customers normally would have high priority during congestion but would receive low priority after 50GB of data use.

A US Mobile agent I reached out to confirmed that there is a throttle after the threshold level of data use is reached. The agent seemed reluctant to mention a specific speed cap but explained that speeds would feel like 2G. Following the argument I made in Unlimited Plans At 2G Speeds Are Bogus, I think it would be more transparent if US Mobile called their plan a 50GB plan. Extra data at slow speeds could just be a little perk. That said, I understand the carrier caving to the pressure to call its plans “unlimited”.

I don’t love the phrasing of “A tiny fraction of heavier data users may notice reduced speeds.” It seems to suggest that only some of the people who pass the threshold will have reduced speeds. As I understand it, US Mobile is imposing a serious speed cap on everyone who passes the threshold of 50GB. I’d suggest an alternate phrasing along the lines of Heavy data users, who make up a tiny fraction of our subscriber base, will experience substantially reduced speeds after 50GB of use..”

Are The Plans Competitive?

US Mobile’s Super LTE unlimited plans look competitively priced for those who only need one or two lines and want service over Verizon’s network. Large families can probably get better per-line rates by purchasing service from Verizon directly (Verizon drops its per-line rates on unlimited plans as more lines are added).

Unlimited plans purchased from Verizon’s Flanker brand, Visible, may be cheaper than US Mobile’s plans, but regular issues and limited device options with Visible may make US Mobile a better bet.

US Mobile also includes some other companies’ services as perks with their unlimited plans. Here’s a screenshot from the carrier’s website:

List of US Mobile Perks

Hidden Fees

On the new unlimited plans, it seems US Mobile is still hiding fees. Most consumers won’t see these fees until after they’ve ordered a SIM card:

US Mobile's hidden fees

Both fees are annoying. One could argue the regulatory recovery fee is at least a fee that many other carriers are also hiding. The $2 per month service fee is unusual.

Pink-Out

Deutsche Telekom (DT), the parent company of T-Mobile, has been making legal threats against companies that use the color magenta in their branding. DT has gone after companies outside of the telecom industry. DT has even tried to force companies to stop using shades of magenta that are different from the shade it uses. TechCrunch has a good article covering the ridiculous story in more detail.

In a funny turn of events, Itamar Kestenbaum, a software engineer at one of the companies DT has threatened, released a Google Chrome extension called Pink-out. Here’s how the app is described (emphasis mine):

Experience the web according to trademark trolls. Deutsche Telekom (aka, T-Mobile’s parent) is out here telling other companies they can’t use pink…so this Chrome Extension makes sure you’re pink-compliant and removes it from all your browsing pages on the web…This extension is free – like the color pink should be.

Visible’s Swap Program Now Offering Better Phones

I previously raved about Visible’s swap program. New customers used to be able to trade in almost any Android phone to get a free ZTE R2. In my case, I was able to trade in an old phone that was several years old for a much better device.

Visible recently made the swap program much better. The ZTE R2 has been dropped from the program, and customers now get to choose between the ZTE Blade A7 Prime and the Motorola Moto e6. I haven’t got my hands on either device yet, but from what I’ve read, both look like solid entry-level phones.

If you have an Android phone that powers on and isn’t already compatible with Visible, it should be eligible for the swap program. You can verify whether a device is compatible by entering its IMEI on Visible’s website. If you get a message that your device is incompatible, hit the “Next” button to continue with the swap program.

Plan Finder Tool Released

Last week, I released a new plan finder tool. Users accessing the tool can answer a few questions about how they use their phones, how budget-sensitive they are, and where they live. They’ll then be matched with a few carriers and plans that are likely to be well-suited for their needs.

Competing Tools

A few other companies have released their own plan finder tools. These tools generally function by assuming the wireless industry is simpler and more commoditized than it is. For example, WhistleOut’s tool appears to assume that cell phone plans have only five features:

  • A host network
  • An allotment of data
  • An allotment of minutes
  • An allotment of texts
  • A price

The allotments are all assumed to take fixed, numerical values. Plans’ prices are also assumed to take simple, fixed values. The host network is simply one of five options (Verizon, AT&T, T-Mobile, Sprint, or U.S. Cellular). Making these assumptions allows many carriers’ plans to be compared, sorted, and filtered with basic math and logic. Unfortunately, the assumptions sweep a lot of important nuances under the rug. For example:

  • Carriers may throttle data speeds or ignore data use from certain applications. Complicated data policies can’t be captured when assuming that plans have simple, fixed data allotments.
  • Pricing may not be fixed. E.g., Mint Mobile has one price for subscribers that purchase 3 months of service upfront and another price for those who purchase 12 months of service upfront.
  • Two services that use the same host network could have different levels of priority during congestion.
  • Factors WhistleOut doesn’t account for, like device compatibility and customer service quality, matter to consumers.

While WhistleOut’s plan finder has a feature for checking coverage, WhistleOut appears to treat coverage as a binary thing⁠—either you have coverage or you don’t. In reality, coverage quality is much richer. You can have mediocre coverage or strong coverage. You can have good coverage at your house but problematic coverage where you work.

CoverageCritic’s Tool

While building CoverageCritic’s plan finder, I tried to account for things like prices, resource allotments, and coverage quality but kept in mind that these aspects of wireless service are complicated and often difficult to fully capture in simple models. While I can’t claim my tool is exclusively driven by hard data, I think my approach makes the tool more useful than competitor’s tools.

CoverageCritic’s tool makes predictions about coverage quality after drawing on geographic information provided by users. At the moment, state-level estimates of coverage quality are combined with user-provided information about population density. Population density proxies for coverage quality and is used to adjust state-level coverage estimates to arrive at location-specific predictions of coverage quality. In the future, I hope to refine the predictions of coverage quality by drawing on much larger data sets from carriers and network evaluators.

At the moment, the tool considers services from about ten carriers, and I plan to add more soon. The tool isn’t perfect, but it should be able to provide most consumers with a good starting point as they search for wireless providers.

Ryan Reynolds Acquires An Ownership Stake In Mint Mobile

Actor Ryan Reynolds recently announced that he has acquired an ownership stake in Mint Mobile. I expect that Reynolds only owns a part of Mint Mobile rather than the entire company, but I’m not entirely sure. In many places, Reynolds is described as the owner of Mint Mobile in a way that doesn’t seem incompatible with him having complete or near-complete ownership of the company.

From Reynolds’ Twitter bio:

From Reynolds’ tweet announcing involvement with Mint:

However, Mint Mobile’s press release makes it sound like Reynolds only acquired partial ownership:

Mint Mobile, the wireless company offering carrier-grade service for a fraction of the cost, today announced actor, writer, producer and mobile phone enthusiast Ryan Reynolds has purchased an ownership stake in the company.

The press release suggests that Reynolds will become involved with Mint’s marketing and communications efforts. I’d love to see Mint come up with ads similar to this one that Reynolds used to promote his gin brand:

FCC Reveals Misleading Coverage Claims

On Wednesday, the FCC released a fascinating report related to the Mobility Fund Phase II (MF-II). The MF-II is a planned program to provide federal funding for network build-outs in rural areas that are underserved by 4G coverage.

To determine which geographic areas were underserved, the FCC requested coverage maps and data from network operators. After reviewing the data and allowing outside entities to challenge the datas’ reliability, the FCC became concerned about the accuracy of the information shared by T-Mobile, U.S. Cellular, and Verizon. The FCC decided to conduct its own performance tests and compare the results of its tests to the information the network operators provided. Here’s what the agency found:1

Through the investigation, staff discovered that the MF-II coverage maps submitted by Verizon, U.S. Cellular, and T-Mobile likely overstated each provider’s actual coverage and did not reflect on-the-ground performance in many instances. Only 62.3% of staff drive tests achieved at least the minimum download speed predicted by the coverage maps—with U.S. Cellular achieving that speed in only 45.0% of such tests, T-Mobile in 63.2% of tests, and Verizon in 64.3% of tests…In addition, staff was unable to obtain any 4G LTE signal for 38% of drive tests on U.S. Cellular’s network, 21.3% of drive tests on T-Mobile’s network, and 16.2% of drive tests on Verizon’s network, despite each provider reporting coverage in the relevant area.

Incentives

When considering the accuracy of coverage maps, I try to think about the incentives network operators face. When advertising to consumers, network operators often have an incentive to overstate the extent of their coverage. However, incentives can run in the opposite direction in other situations. For example, when trying to get approval for a merger between Sprint and T-Mobile, Sprint had incentives to make its 4G coverage profile look limited and inferior to the coverage profiles of other nationwide networks.2

I’m not well-informed about the MF-II, so I don’t feel like I have a good grasp of all the incentives at play. That said, it’s not clear that all network operators would have an incentive to overstate their coverage. A network operator that claimed to offer coverage in an area it didn’t cover may limit competitors’ access to subsidies in that area. However, a network operator erroneously claiming to cover an area may prevent itself from receiving subsidies in that area.

Challenges

After network operators submitted coverage information to the FCC, a number of entities, including both governments and network operators, were allowed to challenge the validity of coverage information submitted by others. Here’s a bit more detail about the challenge process:3

After release of the map of presumptively eligible areas, mobile service providers, state, local, and Tribal government entities, and other interested parties granted a waiver were eligible to submit challenges in the challenge process via an online system operated by USAC. Challengers that requested access to the USAC MF-II Challenge Portal were able to access the provider-specific coverage maps, after agreeing to keep the coverage data confidential, and to file challenges to providers’ coverage claims by submitting speed test data. Challengers were required to conduct speed tests pursuant to a number of standard parameters using specific testing methods on the providers’ pre-approved handset models. The Commission adopted the requirement that challengers use one of the handsets specified by the provider primarily to avoid inaccurate measurements resulting from the use of an unsupported or outdated device—e.g., a device that does not support all of the spectrum bands for which the provider has deployed 4G LTE…During the eight-month challenge window, 106 entities were granted access to the MF-II Challenge Portal. Of the 106 entities granted access to the MF-II Challenge Portal, 38 were mobile service providers required to file Form 477 data, 19 were state government entities, 27 were local government entities, 16 were Tribal government entities, and six were other entities that filed petitions requesting, and were each granted, a waiver to participate.

About a fifth of the participating entities went on to submit challenges:4

21 challengers submitted 20.8 million speed tests across 37 states.

The challenge data often showed failed tests and lackluster speeds in areas where network operators claimed to offer coverage:5

During the challenge process, some parties entered specific concerns into the record. For example:6

Smith Bagley (d/b/a Cellular One) submitted maps of its service area in Arizona overlaid with Verizon’s publicly-stated 4G LTE coverage and the preliminary results of drive tests that Smith Bagley had conducted. Smith Bagley asserted that, for large stretches of road in areas where Verizon reported coverage, its drive testers recorded no 4G LTE signal on Verizon’s network. Smith Bagley argued that the ‘apparent scope of Verizon’s inaccurate data and overstated coverage claims is so extensive that, as a practical matter, the challenge process will not and cannot produce the necessary corrections.’
As part of a public report detailing its experience, Vermont published a map showing its speed test results which contradicted the coverage maps in Vermont of U.S. Cellular, T-Mobile, and Verizon, among others. This map included information on the approximately 187,000 speed tests submitted by Vermont, including download speed, latency, and signal strength. In the report, Vermont detailed that 96% of speed tests for U.S. Cellular, 77% for T-Mobile, and 55% for Verizon failed to receive download speeds of at least 5 Mbps.

After reviewing the challenges, the FCC requested additional information from the five largest network operators (AT&T, T-Mobile, Verizon, Sprint, and U.S. Cellular) to understand the assumptions involved in the networks’ coverage models.

FCC tests

Around the same time the FCC was requesting additional information from network operators, the agency also began its own testing of Verizon, U.S. Cellular, and T-Mobile’s networks. These speed tests took place in 12 states and primarily made use of a drive-testing methodology. As mentioned earlier, analyses of the FCC’s test data suggested that the on-the-ground experience with Verizon, T-Mobile, and U.S. Cellular’s network was much different than the experience that would be expected based on the information the networks provided to the FCC.

What happened?

A lot of the commentary and news articles I’ve seen in response to the FCC’s report seem to conclude that network operators are bullshitters that intentionally lied about the extent of their coverage. I have reservations about fully accepting that conclusion. Accurately modeling coverage is difficult. Lots of factors affect the on-the-ground experience of wireless subscribers. The FCC largely acknowledges this reality in its report:

Providers were afforded flexibility to use the parameters that they used in their normal course of business when parameters were not specified by the Commission. For example, the Commission did not specify fading statistics or clutter loss values, and providers were required to model these factors as they would in the normal course of business.7
Our speed testing, data analyses, and inquiries, however, suggest that some of these differences may be the result of some providers’ models: (1) using a cell edge RSRP value that was too low, (2) not adequately accounting for network infrastructure constraints, including backhaul type and capacity, or (3) not adequately modeling certain on-the-ground factors—such as the local clutter, terrain, and propagation characteristics by spectrum band for the areas claimed to be covered.8

Further supporting the idea that assessing coverage is difficult, the FCC didn’t just find that its tests contradicted the initial information submitted by network operators. The FCC data also contradicted the data submitted by those who challenged network operators’ data:

The causes of the large differences in measured download speed between staff and challenger speed tests taken within the same geographic areas, as well as the high percentage of tests with a download speed of zero in the challenger data, are difficult to determine. Discrepancies may be attributable to differences in test methodologies, network factors at the time of test, differences in how speed tet apps or drive test software process data, or other factors…Given the large differences between challenger and staff results however, we are not confident that individual challenger speed test results provide an accurate representation of the typical consumer on-the-ground experience.9

While the FCC found some of the information submitted by networks to be misleading about on-the-ground service quality, I don’t believe it ended up penalizing any network operators or accusing them of anything too serious.10 Still, the FCC did suggest that some of the network operators could have done better:

Staff engineers, however, found that AT&T’s adjustments to its model to meet the MF-II requirements may have resulted in a more realistic projection of where consumers could receive mobile broadband. This suggests that standardization of certain specifications across the largest providers could result in coverage maps with improved accuracy. Similarly, the fact that AT&T was able to submit coverage data that appear to more accurately reflect MF-II coverage requirements raises questions about why other providers did not do so. And while it is true that MF-II challengers submitted speed tests contesting AT&T’s coverage data, unlike for other major providers, no parties alleged in the record that AT&T’s MF-II coverage data were significantly overstated.11

FCC response

The FCC concluded that it should make some changes to its processes:12

First, the Commission should terminate the MF-II Challenge Process. The MF-II coverage maps submitted by several providers are not a sufficiently reliable or accurate basis upon which to complete the challenge process as it was designed.
Second, the Commission should release an Enforcement Advisory on broadband deployment data submissions, including a detailing of the penalties associated with filings that violate federal law, both for the continuing FCC Form 477 filings and the new Digital Opportunity Data Collection. Overstating mobile broadband coverage misleads the public and can misallocate our limited universal service funds.
Third, the Commission should analyze and verify the technical mapping data submitted in the most recent Form 477 filings of Verizon, U.S. Cellular, and T-Mobile to determine whether they meet the Form 477 requirements. Staff recommends that the Commission assemble a team with the requisite expertise and resources to audit the accuracy of mobile broadband coverage maps submitted to the Commission. The Commission should further consider seeking appropriations from Congress to carry out drive testing, as appropriate.
Fourth, the Commission should adopt policies, procedures, and standards in the Digital Opportunity Data Collection rulemaking and elsewhere that allow for submission, verification, and timely publication of mobile broadband coverage data. Mobile broadband coverage data specifications should include, among other parameters, minimum reference signal received power (RSRP) and/or minimum downlink and uplink speeds, standard cell loading factors and cell edge coverage probabilities, maximum terrain and clutter bin sizes, and standard fading statistics. Providers should be required to submit actual on-the-ground evidence of network performance (e.g., speed test measurement samplings, including targeted drive test and stationary test data) that validate the propagation model used to generate the coverage maps. The Commission should consider requiring that providers assume the minimum values for any additional parameters that would be necessary to accurately determine the area where a handset should achieve download and upload speeds no less than the minimum throughput requirement for any modeling that includes such a requirement.

Reflections

The FCC’s report illustrates how hard it is to assess network performance. Assumptions must be made in coverage models, and the assumptions analysts choose to make can have substantial effects on the outputs of their models. Similarly, on-the-ground performance tests don’t always give simple-to-interpret results. Two entities can run tests in the same area and find different results. Factors like the time of day a test was conducted or the type of device that was used in a test can have big consequences.

If we want consumers to have better information about the quality of service networks can offer, we need entities involved in modeling and testing coverage to be transparent about their methodologies.
