While trolling thru Telecom's roaming partners in the US website http://www.telecomroaming.co.nz/ all looked normal until I saw this one ..
Verizon 850GSM and 1900GSM.
I emailed the roaming help desk with
"Just having a look at Telecom’s roaming partners in the USA and See that Verizon is listed as a GSM roaming partner
You may want to recheck that as I understand that Verizon is a CDMA and LTE carrier only .."
They came back with
"We can confirm that Verizon is our business partner in the US. Verizon network supports GSM (850/1900 MHz) and LTE (700 MHZ) frequency. When you travel in USA with an XT mobile, it will normally connect to AT&T or T-mobile as they have the largest coverage. These networks supports 2G and 3G."
Anyone one confirm who is correct.
