Why does my iPhone say SOS?

Hello! That means that you have no cellular reception. The "SOS" means that the Emergency SOS Satellite feature is still available in case of an emergency.

If you find that you're in an area that has cellular service but you still are not getting a signal on your iPhone, I would recommend making sure cellular data is enabled.

1. Open Settings
2. Click Cellular
3. Make sure that in the ESIM section, "Turn on this Line" is enabled. (This is only applicable for iPhones with an ESIM, international iPhones still use SIM. In that case, make sure it's inserted correctly.

If these steps did not help, I would recommend restarting the phone. If you're still having issues, I would recommend taking the phone to be seen by a professional. Hope this helps!

If it doesn't help, remove and reinsert the SIM card.

If it doesn't help visit your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.

Ask also to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.
