Problem may have been limited to LTE
T-Mobile US customer service told users to switch their smartphones to 2G/3G only in order to restore service for those who could not send or receive text messages during the last hours of June. This resolved the problem for many users, and now the network is apparently back to normal.
Last night the “un-carrier” started hearing from customers who could not use text messaging on their smartphones. One user also complained that the customer service reps were not answering calls in South Florida.
T-Mobile US used Twitter to respond to its frustrated customers, assuring them that engineers were working to resolve the problem, and suggesting that users leave the LTE network temporarily until the problem was resolved. This fixed the problem for a number of users.
By Wednesday morning, T-Mobile US was tweeting that the texting issue was resolved and thanking customers for their patience.
TmoNews has been following this closely and has had no reports of any problems since last night.
Some T-Mobile US customers seem to have avoided the problem by staying on Wi-Fi networks. Of the four major U.S. carriers, T-Mobile US has been the most aggressive in offering voice over Wi-Fi, meaning that customers can text, watch videos and make voice calls on Wi-Fi. T-Mobile US supports handover from cellular to Wi-Fi and vice versa, meaning that data sessions and calls can transfer between networks.
