T-Mobile says 19 devices won’t work with network by January 2021 December 23, 2020 If you own a smartphone that is pretty outdated by a few years and you’re on the T-Mobile network, you better wait for an email from your carrier soon. An internal document lists around 19 devices that will not be able to connect to their network by January 29, 2021. Most of the devices in the list are from 2014-2015 so it might really be time for owners to upgrade to a newer device if they want to continue being on T-Mobile and probably other networks as well in the long run.
