No compatibility between Verizon Carrier and SM-N900W8
As far as I know, Verizon is using the N900V on their network which requires CDMA band.
I bought a SM-N900W8 from Telus Canada and after having it unlocked, I was unable to have it registered under my Verizon account.
So, not wanting to pay the outragious roaming price that we have from our greedy Canadian Carriers, I purchased an AT&T Pay as you GO sim card.
This is due to the use by Verizon of CDMA band which isn't supported by most Canadian Cellphone that requires at least WCDMA OR LTE/GSM Band.
So, if you're planning to travel the USA and are looking to get an American SIM Card, most likely, verizon will not be an option for you (they're expensive anyway)
AT & T and T - mobile supports the GSM as far as I know.
