I've got a galaxy S7 edge from Verizon that is unlocked, and an unlocked ZTE axon 7. Will they work on T-mobile?
That is true for the legacy networks but with LTE being more robust these phones can run on LTE more then the older GSM and CDMA networks.verizon is CDMA... where as tmobile is GSM so Idk if they will be capable of their full potential.
Why band 20?Will an unlocked AT&T iphone 6S work on Tmobile? Wife won't switch to Android. I'm really wanting to know if it has band 20.

To elaborate on that, LTE (Long Term Evolution) is the evolution of GSM. If you're on Verizon, and it shows "lte", you're not using the cdma radio at all. In fact the new HTC U11 is certified to work with Verizon, and it doesn't even have CDMA radios. There are very few areas that Verizon covers, that rely on it's legacy CDMA network. Also as part of their bid for frequencies a couple years back, they were required to not lock their phones down (sim lock). So you can pick up a Verizon phone, throw an ATT or T-Mobile (or really any of the hundreds of global carriers), and it'll work. As always, make sure the phone you're using supports the frequencies that your chosen carrier is using.
