Can someone school me on CDMA and GSM? I have a verizon phone

The answer is no.

It depends on your phone. What bands/frequencies is your phone compatible with?
Then find out what bands/frequencies t-mobile uses (probably 2,4, and 12). If your phone is compatible with bands 2, and 4 then you should be golden. if it's also compatible with band 12 then you are even more lucky.

Aright, thanks. What about unlocking?

Would I have to unlock my verizon phone if the bands are compatible?

Americans and a few other irrelevant shitholes use CDMA (no SIM). Everyone else uses GSM.

Call verizon, or search their site to find if they have an automated unlock request page to fill out. It should be free if you meet the requirements (paid off phone, no outstanding balance, and etc.)
>Would I have to unlock my verizon phone if the bands are compatible?
You would have to unlock your phone regardles if you plan to use it with another carrier.
it look like you should be fully compatible for 2g, and lte while being partially compatible with t-mobiles version of 3g/4g.

Used to stick with sprint var boost, but fuck them, making bold move back to tmobile var metropcs

CDMA was newer and used in the United States
GSM was older and used Outside of United States.
They both kind of Merged into this big bull shit ball of multi radio technology.
