Unlocked ATT Branded HTC One will not get service with Verizon SIM. Help?

[jdy3239]

I recently gave my friend my 32gig HTC One that is ATT Branded. He has Verizon. I got the phone unlocked, and I put in his Verizon SIM and while it accepts it, hes not getting any service at ALL. Occasionally he will get 1 bar of 4G LTE for a few seconds and then it drops to no service. Any help guys?

Verizon runs it's voice/text service on CDMA, which is not supported by the AT&T One. Verizon offers it's LTE on Band 13 in most areas, though there are a few markets where Band 4 has started to be deployed. It's this Band 4 that it picked up because it's the only frequency supported by the AT&T One since AT&T also has LTE on Band 4 in some areas. Either way, it's not very developed on Verizon yet and you won't be able to make calls or text with it.

So could it possibly get service when band 4 is deployed in my area?

It could get data service if band 4 is deployed in your area, but it's not going to be deployed in every location. It's mostly only designed to help reduce congestion in larger metro areas. I know Verizon sold all of it's band 4 spectrum in my city to T-Mobile which has since deployed it as their LTE here.

But since voice/text is over the CDMA network, it will never gain that functionality on Verizon.

It'll be years before talk/text/data will all use the LTE network?
