T-Mobile says "GSM-capable phones that support Band II (1900 MHz) or IV (1700/2100 MHz) are compatible with T-Mobile's network".
*I do agree that older CDMA only phones won't work on other carrier networks, but that's just not the case with newer phones anymore.
But they wont work fully since it doesnt support all the bands.
Some phones do.. like nexus 5x 6p, they have all bands for both carrier system types even including band 12 for t mobile.
While you may get all features in town.. then drive 50miles to somewhere else and have no signal.
OTOH it could be every tower within 300miles uses the band you have available.. you just dont know.
For example if you took that phone to AT&T which has
Quote:
AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently.
You can see where you could have holes in coverage depending on the towers..
here is an article that is a little more in depth and explains bands and how they are deployed.
