T Mobile 30 Day Sim

If this happens, you will be charged per minute or text by the network. Good thing there are T Mobile 30 day sims with fixed rates.
Right now, there are two types of T Mobile 30 day sims with fixed rates. If you choose one of these deals, you will have a set number of credits every month.
