When we were in Arizona last winter we had Verizon internet. They sent us that same kind of letter. Then we found out later they charged us an extra $130.00!!!! I was furious. Apparently, they don't have "roaming" charges.....but if it says "roaming" you have a limit....then if you go over the limit, they charge you more!!! I thought roaming charges were only on the phone. And at that time, we had NOT received any notice that we were in a "roaming" area. Verizon will never get my business again.
