I have an opportunity to go to New Zealand for 4 months to work. I will be provided a phone while there so I was anticipating using my iPhone in wifi-only situations. I discovered that Verizon will let me suspend my phone service for up to 6 months but I am concerned about losing my grandfathered unlimited data plan. Can anyone point me to Verizon documentation that will confirm or alleviate this concern? I also have read that my suspended service will automatically re-activate after 90 days and it would be my responsibility to suspend it again until I return from NZ.
