I would rate the service 10+
I like the fact that virtually no matter where I travel, I have service. I have been with Verizon for 8 years now, since they were Airtouch, and have never found another provider who can compete with Verizon's network. I like them so much, I went to work for them 10 months ago.
If I have to come up with a dislike, it would be that the phones are missing some key personalization features. However, since I went to work for the company, I have realized why the phones are thusly crippled. I also have learned the simple ways around some of the features.
