Roaming in your local area, one of the arch enemy of many Tracfone owners. So how exactly do you take your phone off of roam? Short answer is you really can't without contacting customer service that is. So which phones roam and why do it happen? Roaming in your local area usually happens in fringe coverage areas. That is, areas that are in the further reaches of the carrier Tracfone assigned you. It can also happen in dead coverage areas. There are two main reasons why this happens.
1. You entered the wrong zip code when activating the phone or maybe you entered another zip code hoping to get different choices of phone model. If you are thinking about a Tracfone, use this tool How to tell which Technology Tracfone will assign for my zip". This handy tool will tell you what the technology for that zip is and what the possible carriers will be.
2. Tracfone has no inventory in your zip code so they assigned you the closest number possible. This is a rear case but does happen. It is more common during the Christmas season when people are activating a lot of phones. So if you are thinking about getting a Tracfone, buy one before Chrsitmas!
In either case, you will need to contact customer service. For reason #1, they will probably swap out your phone. For reason #2, customer service will try to get their Line Activations department to find you a good number.
