We have done this same dance in the past. Ends up easier (and cheaper) to get ATT go-phone. We add a new sim card and pay $15 for 30 days. You can pick ur plan - we do the $2/day flat charge for unlimited calls/texts. This year we are getting two so the kids can wander and still have a phone to reach us and check in. Dealing with Verizon and "hoping" we don't get charged is not worth the hassle.
