Are Sprint and Verizon phones compatible

Is the iPhone 6 model A1549 (CDMA) compatible with T-Mobile?

I was too excited to complain about the 5 Series and older models about their lack of compatibility / interchangeability between carriers.

Ok as far as I know, when it comes to the 6, if you buy a Verizon phone (or any other phone) these days, it works with Verizon as well as any GSM carrier worldwide. This is because Verizon phones have also come with GSM cellular bands on all phones since the appearance of LTE. And more importantly, these tapes are unlocked, which means they can be used with any wearer worldwide. This is due to the fact that Verizon has made an agreement with the FCC that their phones should be unlocked in exchange for frequencies in LTE bands or the like. I wish the FCC had done the same with Sprint. Yes, a Verizon iPhone 6 works with T-Mobile and any other GSM carrier worldwide that accepts bringing your own phone. Pretty much all network operators around the world now accept bring-you-own-phone.

After all, an unlocked T-Mobile iPhone 6 has no CDMA tapes at all. There are only GSM bands as T-Mobile only uses GSM cellular frequencies. As a result, it won't work with CDMA providers like Verizon and Sprint.

Verizon iPhones have been the best pick since the 5 because they work with most carriers in the US. I have a really factory unlocked 6, model 1586 (note, not a Verizon). It is designed to work with EVERY carrier worldwide. But I didn't make sure it works with the Verizon and Sprint weird balls. It has both GSM and CDMA bands. I currently have it at AT&T.
