Temporarily turn SIM off

Sometimes, you might need to temporarily disconnect your SIM card from the mobile network, like when you’re traveling, have privacy concerns, or are troubleshooting network issues. You can do this in Settings by turning the SIM card off and back on when you’re ready to use it again.

Remember that turning off your SIM card disconnects you from the mobile network, so you won't be able to make or receive calls, send or receive messages, or use mobile data with that SIM card until you turn it back on.

  1. Go to Settings > Network & internet > SIMs & mobile network.
  2. Next to the SIM name, turn the SIM off or on .
