A corrupted, dislodged, or damaged SIM card can also be the main reason why your phone is getting this error. To rule out SIM card data corruption and displacement, removing and reinstalling the SIM card is the last recommendation. And here’s how it’s supposed to be done:
- Turn off your iPhone completely. This is highly recommended to avoid damaging the SIM card components or your phone itself.
- While the phone is turned off, insert the SIM ejector tool into the small hole on the SIM tray located on the right side of your phone.
- Gently push the tool until the tray ejects.
- Remove the SIM card from the tray. Also care to examine the card for any visible signs of damage like scratches and liquid traces. If there’s none, insert the SIM card back it into the tray with the gold contacts facing down and the notched edge on the upper right

What to do if your iPhone 11 still has no service error?
Performing a factory reset and restoring your iPhone 11 in iTunes can be considered among the last options if none of the given solutions worked. Persistent symptoms and errors are usually inflicted by complex system flaws. In this case, it’s possible that your phone’s cellular network system has been corrupted and therefore needs a full reset. To deal with major system errors, a factory reset or iOS restore is usually needed. If a factory reset reset doesn’t solve the problem, restoring your iPhone in recovery mode or DFU mode will be your next options. These iOS restore procedures usually render positive outcomes when it comes to resolving major system errors but you have to note though that these methods will also wipe all your saved files on the internal memory. Creating a backup is therefore recommended beforehand. You may opt to troubleshoot your device further or just escalate the problem to your network carrier.
If you prefer the latter, then you should now contact your network service provider or carrier to verify your account status and make sure all your services are active. As mentioned earlier, account-related problems can also be the underlying cause. If everything is good with your account, ask your carrier to make further assessments with your SIM card.
SIM card issues from SIM data corruption to physical/liquid damage could also be the main reason why your iPhone is unable to obtain cellular network signal and just prompt a no service error on the status bar. Inserting the SIM card into your other phone that supports the same type and SIM card size can also help you to determine whether or not the SIM card is working. If it still doesn’t work and your other devices shows the same no service error when using that SIM card, then the problem is with your SIM card. At this point, you can request for a new SIM card replacement from your network provider/carrier.
