As the Primary Account Holder, you can suspend a line on My T-Mobile.

Account suspension guidelines

• When you suspend a line, all calls, text messages, voicemail, and data services are suspended. You’ll keep your number and monthly plan, but monthly fees are prorated depending on the type of suspension.
• If you previously suspended your line within the last 12 months as a Seasonal Suspend the option/button to suspend the line on My T-Mobile will not be displayed until the end of the 12-month period.
• You can suspend your monthly T-Mobile service for one of the following reasons:
  • Your device was lost or stolen.
  • You won't be using your phone for a while.
  • You're about to enter active military service.

For more details on suspensions, see Account suspensions. When you suspend your line, your account might require a minimum monthly fee, payments for your plan, and payments for any equipment on a payment plan for the remaining term of your agreement. Also, if you have an account with several lines, you can only suspend one line at a time.
