Since Google Wallet is blocked (thanks a lot, VZW!), can we use Isis or some alternative instead?
You need a NFC SIM card to use Isis.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
Yes you can use Isis. As Ann154 indicated, you need an NFC SIM card for the Isis Mobile Wallet to operate. These are free of charge from Verizon. Just call and they will ship one out to you.
You can use the Isis wallet in most places that accept mobile payments, I have been using Isis in the Minneapolis/St. Paul area for about 2 months now and have had no problems.
