T-Mobile has recently announced the discontinuation of its 2G network, prompting customers to upgrade to newer devices. Despite previous warnings, many customers have yet to make the switch, leading T-Mobile to keep its 2G network operational for the time being. The carrier is offering free 5G phones to those who upgrade, both in-store and over the phone. While the 2G network is still available, it will eventually be phased out completely. Now is the perfect time for customers to take advantage of T-Mobile's offer and make the switch to a more advanced phone.
