Get them to not like you!
Get them to not like you!
It may be more difficult with T-Mobile than other carriers but try to get into a digital roaming area and use as many minutes as you can. Also, if you have any unlimited time, such as evenings and weekends, use as many minutes as you can, such as dial a land to a land line and leave it on all night and all weekend. T-Mobile may have to pay for time on other networks and this is how you may get them to "not like you". A nephew got booted from his carrier (Verizon or Cingular, don't remember which) because he went to school a long distance from home and eventually they asked him to leave. BTW, they also tried to charge him an early termination fee for leaving before his contract was up! He immediately said "no way" and told them they could either cancel him or he was going to remain using their service and let them absorb the extra out of area costs. They eventually released him and did not ding him for the extra fee.
Like I said, I am not sure if this will work with T-Mobile. Depending on the contracts they have with other networks this may or may not work as it does on other carriers.
Also, be very careful about where you go out of your area to do this. I live in a state bordering Canada and there are a few northern carriers that T-Mobile told me they don't have good contracts with and users get charged expensive rates on those networks.
Good luck.
