As soon as AT&T shut down 2G I switched to T-Mobile.
Now I am hearing rumors that T-Mobile is shutting down 2G at the end of 2020.
I have an Ebay bushiness unlocking AT&T older phones for use on T-Mobile. Shutting down 2G will make all these phones useless, creating an unimaginable amount of e-waste and destroying me and many others source of income.
A large amount of people still use these older 2G-only phones, due to their reliability and people disliking the lack of options, poor repairability, and poor build quality in the modern phone market.
Perhaps you can add a fee for 2G service to help keep up the cost of maintaining the older network, but I beg, do NOT shut down 2G.
ESPECIALLY because of the COVID-19 pandemic, it is an incredibly terrible idea to force the shutdown at this moment. Many businesses will not be able to cough up the cost for new equipment that relied on the legacy 2G network.
