DETAILED INFO

Get info about dual SIM devices

A dual SIM phone is one device that can have up to two active numbers, plans, or accounts. You get this convenience on one device because it has two separate SIMs:
  • A physical SIM: A plastic card inserted into your phone.
  • An eSIM: A digital SIM activated through the network.

Good to know: Some dual SIM devices are really Dual SIM, Dual Standby (DSDS) devices. With these, both SIMs can be active at the same time.

Ready to activate? Learn how

Texting
You’ll have to choose which phone number you want to use before sending a text, picture, or video message. But you can get messages from either number at any time.

Using data
With some devices, you may have to toggle between default services. But other devices may offer the option to switch services based on the SIM used for active calls. You can find this option in your device settings.

Connected to Wi-Fi®? Your device will use it for both numbers (even if you’re on a call).

Calling
To make a call: Choose the phone number you want to use before you call. Or, allow the phone to default to the last number used. You can put a call on hold for one number and place a call from the other – all on one device.

Already on a call? You’ll get a notification for incoming calls on the number you’re using. Plus, incoming calls will ring on your second line.

Heads up: Have FirstNet®? You can buy dual SIM devices, but if you activate the second SIM, it may interfere with your FirstNet connection in some instances.
