According to this site, there are three models of iPhone 6: A1549(GSM), A1549(CDMA), and A1586. It says the A1549(CDMA) model "supports all the same spectrum" as its GSM counterpart, but also supports additional spectrum making it a "world phone". Does this mean the unlocked T-Mobile iPhone 6 is essentially the Verizon model with its CDMA capabilities disabled? Could one go to an Apple Store, pay for a Verizon iPhone 6 in full, and pop in a T-Mobile SIM with no side effects?

Best Answer

The GSM side of Verizon phones are unlocked and will work on domestic carriers but there is no guarantee all features will work. It is not the same for Sprint, the GSM side of that phone is unlocked and unlocking it will only allow it to work with non-domestic GSM carriers.

A1549 (CDMA):

This is considered as the world phone version. It supports all the same spectrum frequencies as the A1549 (GSM) and also includes CDMA EV-DO Rev. A and Rev. B (with 800, 1700/2100, 1900 and 2100 MHz bands). Besides, it works on UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz), GSM/EDGE (850, 900, 1800, 1900 MHz) and 4G LTE bands include bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29. The model is compatible with Verizon and Cricket in the US. However, if you buy an unlocked Verizon phone, you will be able to use it on any other GSM networks like T-Mobile and AT&T as well.

Best is to double check with T-Mobile.
