I think so, they both use GSM while Verizon and Sprint would use the CDMA version of M8.
If it has a bad ESN then no as they share the same list for bad ESN phones

How do I convert a t-mobile HTC one m8 to Verizon?

Excuse my noobness but I have tried to search for this answer without success. There are various how to's on how to convert a Verizon htc one m8 to t mobile but none on how to convert a t-mobile HTC one m8 to be used on Verizon. I have the unlock code and that part worked but it would not connect at all. What can I do here? Willing to flash or do anything at this point.
Yes I had to cut the Sim card in order to make it fit.
It wont work. TMO is a GSM / LTE device and Verizon is CDMA / LTE. At best you might get some data but thats it.
Buy a Verizon one if thats what your wanting.

Got a HTC One M8 from T-Mobile, now lte support for AT&T

Hi everyone, I just bought a HTC One M8 from Ebay that is unlocked from T-Mobile and that cost be $169. Do you guys think this was a good deal? All that aside, I want to use that phone on Cricket that basically uses AT&T bands. I see that the lte bands for HTC One M8 only supports 4,17 while AT&T used 2,4,5,17. I know that Oneplus One had the same problem with not having lte bands 2 and 5 but people had it working for AT&T lte. Just wanted to know is there anyway to unlock the bands 2, 5 for AT&T full lte bands? Thank you.

4G/LTE not working

I bought a Verizon unlocked htc one m7 and then used t mobile sim in it. Everything works fine except I can't get 3g or 4g, it just stucks on edge? Is this software or hardware problem? Isn't there anything to solve this?

Verizon branded one M7 will not support any US GSM bands except 1x and Edge. This means you will not get 3g or 4g on T-mobile, AT&T, cricket, etc.
