Can't see my cellular plan, how can I fix it?

First of all, you need to know what kind of SIM-card is used in your device: eSIM or nano-SIM.

If you don't see your eSIM plan

Configure your cellular plan with eSIM.
Open Control Center and see if both of your carriers appear in the status bar.
Make sure there are no service outages in your area and your carriers support coverage.
We recommend you also check if your cellular plans are set up, ready to use, and don’t have a billing-related blockage.

If you don't see your nano-SIM plan

Make sure that your nano-SIM card is put properly in the SIM tray:

Remove the SIM tray and inspect the SIM cards for signs of corrosion or damage.
Remove your SIM card from the SIM tray, and put the SIM card back.
Make sure that you close the SIM tray properly. It shouldn't be loose.
Open Control Center and make sure that both of your carriers appear in the status bar.

If the nano-SIM card still doesn't work, doesn't fit or is bent or damaged, or if you see "Card is not compatible with LTE" on your iPhone, contact your carrier for a nano-SIM card reissue.
