A small number of T-Mobile customers could wake up on Aug. 3 with zero bars on their phones -- unless they take action now.

After two years of outreach to subscribers, T-Mobile is turning off its 2G network. Any T-Mobile subscriber with an outdated phone can get a free 5G-capable replacement from the carrier via mail or by bringing their old device, in any condition, to a T-Mobile store.

A T-Mobile representative wouldn't comment on how many customers the change impacts, but Roger Entner of Recon Analytics estimates it affects 1% to 2% of subscribers.

"These are low-usage, glove-box case scenarios," Entner said, adding that offering free device replacements is a customer-friendly move by T-Mobile.

For most people, shutting down the 2G network won't cause much disruption, since modern smartphones rely mainly on 4G LTE and 5G. Those newer standards have transformed cellular service from slow, text-only connections into fast digital networks that support cloud computing, high-definition streaming and billions of connected devices.

According to T-Mobile's Network Evolution page, customers transitioning from legacy 2G devices will be able to take advantage of faster data speeds, advanced features such as T-Satellite satellite data service and improved 911 location accuracy.

When 2G networks went online in the 1990s, smartphones weren't even a glimmer in anyone's eye. 2G brought digital signals, encrypted voice calls and SMS text messaging to the mobile phone experience.

You would have to go back to the original iPhone in 2007 to find a smartphone that works only on 2G and was available only on AT&T's network (it launched as an exclusive to Cingular, which later rebranded as AT&T Wireless). The first Android phones didn't hit the market until 2008, and those were 3G-compatible at launch.

AT&T retired its 2G network in 2017, and Verizon followed suit in 2020. T-Mobile previously shut down its 3G network in 2022, along with Verizon and Sprint.
