Get help with Dual SIM with two nano-SIM cards

Learn to fix any issues you might encounter when using Dual SIM with two nano-SIM cards and your iPhone XS Max or iPhone XR in China mainland, Hong Kong, or Macao.

Check your plans

  • To use two different carriers, your iPhone must be unlocked. Otherwise, both plans must be from the same carrier. If a CDMA carrier provides your first SIM, your second SIM won't support CDMA. Contact your carrier for more information.
  • Both plans must be set up and ready to use.
  • Make sure that you're in an area with supported coverage and that there are no service outages in your area.

iPhone XS Max and iPhone XR purchased in China mainland, Hong Kong, and Macao can use two physical SIM cards. If you aren't in China mainland, or if you're in Hong Kong or Macao and have an iPhone XS, get help with Dual SIM with an eSIM.

Make sure to install both nano-SIM cards properly

If you think that neither SIM card—or SIM-card slot—works, follow these steps:

  1. Remove the SIM tray and inspect the SIM cards for signs of damage or corrosion.
  2. Remove your SIM cards from the SIM tray, then put the SIM cards back as displayed here.
  3. Make sure that you close the SIM tray completely, so that it isn’t loose.
  4. Open Control Center and make sure that both carriers appear in the status bar.
  5. Go to Settings > Cellular or Settings > Mobile Data and make sure that you see both plans.
  6. Tap each plan and make sure that the information is accurate.

Contact your carrier for a new nano-SIM in either of these situations: 

  • If a SIM card doesn't work in either SIM slot.
  • If a SIM card doesn't fit or is bent.

If the primary or secondary SIM slot doesn't work with more than one SIM card, remove the SIM card that works and insert only the SIM card that isn't working. If it still doesn't work, contact Apple Support
