Google Fi After The T-Mobile & Sprint Merger

Google Fi brought a lot of innovations and customer-friendly features to the wireless market. I’d argue that Fi’s biggest innovations have been in network switching. Subscribers using “Designed for Fi” phones can automatically switch between coverage from T-Mobile, Sprint, and U.S. Cellular’s networks. Losing Sprint Fi’s network switching is about to become a lot less […]

Varying Policies For Prepaid Plan Auto Pay Discounts

Verizon and AT&T both offer discounts on most prepaid plans when subscribers enroll in automatic payments. The carriers have different policies for when discounts kick in. With AT&T, customers can enroll in automatic payments when they first place an order, and the discount for automatic payments kicks in immediately. I like AT&T’s approach. It’s simple. […]

Variable-Rate Pricing, Network Switching, and Mobile X

Urban planners have a joke: “You aren’t in traffic; you are traffic.” While most people consider how long they’d have to wait in traffic if they travel, almost no one thinks about how much worse they’d make traffic for everyone else. Conventional tolls charge road users the same rates all the time. Variable-rate tolling is […]

Verizon’s Revamped Shared Data Plans

Verizon used to offer several different plans with shared pools of data. The carrier has now simplified its offerings with only two shared data plans. Both plans include unlimited minutes and texts.

<i>5G+</i> Brilliant Marketing From AT&T?

A while back, AT&T began calling some its 4G service 5GE. It tricked consumers into thinking they were getting 5G when they weren’t. It was bullshit. Now, AT&T is calling its millimeter wave (mmWave) service 5G+. In some ways, the 5G+ label could confuse consumers. Verizon’s 5G service uses pretty much exclusively mmWave right now. […]
