You might have a different family plan, but my 10 GB is not international data

Exactly the same thing I am saying. I think we are having a semantics problem. You do not need to renew your Lime plan, you can buy it buy the GIG, for a month time period. If someone texts my US phone it's 50 cents to me and free to the texter. You do not need Lime to get a phone, any unlocked device will work.
