Can I purchase a sim card in Mexico (Cabo San Lucas) for my Total Wireless (really a Verizon CDMA) phone. I want to communicate (call & text) with the US (and Mexico) and use data. I found Sim cards but they all seem to be for GSM phones only. It would seem like I could buy a Sim card in Mexico that would work in my phone - but I guess not, if Mexico only has GSM service?!? Can anyone help?
