Use dual SIM phones

Learn how to manage calls, texts, and data use with your dual SIM phone.


DETAILED INFO
A dual SIM phone is one that can have two active numbers, plans, or accounts. You get this convenience on one device because it can have two separate SIMs:
  • A physical SIM: A plastic card inserted into your phone.
  • An eSIM: A digital SIM downloaded to compatible devices.
You may have a physical SIM and an eSIM or multiple eSIMs.

Good to know: Some dual SIM phones are really Dual SIM, Dual Standby (DSDS) devices. With these, both SIMs can be active at the same time. Want to know more? Go to Device Support and choose your device. Select Device info, then eSIM

Calling

To make a call: Choose the phone number you want to use before you call, or 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.

Texting

You’ll have to choose which phone number 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. 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).
