I doubt they want you to leave. Especially since you`ve been with T-Mobile for over 10 years. Have you ever tried to call back to talk to them? If so, what did they say? If you have a guaranteed rate, we will not increase your monthly recurring service fee („recurring fee“) for the period that applies to your pricing plan or, if no specific period applies, as long as you remain a reputable customer in a qualifying pricing plan at all times. If you change your plan, the price guarantee will apply to your new rate (if applicable). The price guarantee is limited to your recurring costs and does not include, for example, additional features, taxes, surcharges, fees or charges for additional functions or devices. If your service or account is limited, blocked or terminated, and then reinstated, you may be charged a reactivation fee.

Some activities and uses of our services and your device are permitted and others are not.
