> AFAIK, in the US, T-Mobile still has a 2G network.
They do but most won't be able to use a phone this old on it. Reason being the SIM application was taken out of the issued sim cards years ago for T-Mobile (something like 6 years or so at this point). Newer 3G-era cellphones use the USIM application and can fall back to the 2G network.
So the only way to still use a device that's pre-3G (circa-2007 or so) on the 2G network is to have a SIM that's been activated the whole time. T-Mobile will not activate expired SIM cards that still contain the application.

EDIT: Funny thing about 3G-era phone support, you can use a euicc (removable ESIM) on a phone from 2007 (I used Sony Ericsson K850i) and it will work just fine with an activated esim to access 2G.
