When Will 3G Be Phased Out?

Last updated: October 22, 2021 Major U.S. network operators are phasing out their 3G technologies. Below, I share my impressions about the status of the major networks’ 3G phase-outs. It’s possible some network operators won’t stick to their deadlines (plenty of early deadlines have already been pushed back). Verizon Verizon has twice set and then […]

Your Mileage May Vary

It’s common to see some consumers giving a cell phone carrier glowing reviews while other consumers publish long rants about the same carrier. When it comes to cell phone service, your mileage may vary. Cell phone users differ from each other in a lot of ways. It should be unsurprising that a T-Mobile customer in […]

Google Voice Review

I love Google Voice, and I want more people to know how awesome it is. I find Voice to be most useful when paired with a wireless device, but it’s also great as a stand-alone service you can use from a desktop. Stand-alone Google Voice The stand-alone, personal version of Voice is free and easy […]

5G: Awesome But Overhyped

5G network technologies have the potential to deliver far faster wireless speeds than 4G technologies. 5G will also enable data transfer with much lower latency (delay) than 4G. The technology is awesome. However, I’ve had a nagging suspicion that aspects of 5G are being overhyped to consumers. Earlier this month, I attended the Big 5G […]

Network Evaluation Should Be Transparent

Several third-party firms collect data on the performance of U.S. wireless networks. Over the last few months, I’ve tried to dig deeply into several of these firms’ methodologies. In every case, I’ve found the public-facing information to be inadequate. I’ve also been unsuccessful when reaching out to some of the firms for additional information. It’s […]

Fancy Phones: Now An Even Worse Deal

About twelve years ago, Apple released the first iPhone. It was an expensive device, but the original iPhone had all sorts of features that the competition lacked. In 2012, the year the iPhone 5 was released, there were still significant differences between the latest, high-end phones and phones that were sold at lower price points. […]

Magical Growth in Subscriber Numbers

Yesterday, one of my favorite journalists covering wireless, Mike Dano, published an article with the title “Why Wireless Carriers Magically Keep Growing Every Quarter.” Dano notes that there’s been a roughly 2.5% growth in wireless subscribers for each of the past several quarters. This growth rate is tricky to make sense of: I’m not convinced […]

See You at The Big 5G Event!

I’ll be at the Big 5G Event in Denver on May 7th and May 8th. If you will be at the conference and want to connect, please reach out. If you won’t be there, I expect to write about some highlights after the event.

Lies, Damned Lies, and AT&T’s 5GE

Fortunately, the sentiment behind this quote isn’t always accurate. Sometimes statistics can reveal lies. AT&T has recently taken a lot of heat for misleadingly branding advanced 4G networks as “5GE.” Ian Fogg at Opensignal published a post where he draws on Opensignal’s data to assess how AT&T’s 5GE-enabled phones perform compared to similar phones on […]
