T-Mobile is booting customers from its oldest plans

T-Mobile is retiring its oldest plans, including those from the 3G era, and moving customers to current rate plans. This change affects customers who have been with T-Mobile for over 15 years. Affected customers are being notified and will be transitioned to modern plans. This move is likely to cause inconvenience for some customers. T-Mobile's goal is to provide customers with more modern and efficient plans.
