Using Verizon in Mexico with the Pure... Not that easy

So, my wife and I are heading to Mexico next week and I wanted to be able to have international usage for emergencies. My wife is using the S6 edge purchased through VZW and I of course have my X Pure. We were able to add an Int'l plan on her line but with mine it didn't work. The call got escalated to support and the rep mentioned that the phone may not be in registered in the system (I just cut my micro-sim and placed it in the pure). He said he was going to fill out a form adding the IMEI to the system and that should fix the issue in 3 business days. Have any of you guys heard of this?
