How To Fix iPhone No Service Issue After iOS 13.3


No service error on an iPhone usually occurs when no network signal is detected. As a result, the iPhone won’t be able to process network-related operations like sending and receiving of SMS messages. Your iPhone will also not be able to receive and can’t make calls at this moment. There are many possible reasons as to why this error transpires. In many cases, temporary network problems such as network outage or scheduled maintenance are found to be the underlying cause. An iPhone no service error can also occur when the SIM card, SIM tray, or any other network component is damaged. No Service error that is attributed to a damaged iPhone component typically requires service. This is when a technician’s aid is needed.

There are also some cases, when the no service error is tied to account problems. Software-related No service error on the other hand can still be remedied at home by some workarounds. The procedures I’ve demonstrated below can be deemed among the possible solutions to pertinent issues on an iPhone. Read on to learn what to do if your iPhone keeps prompting a No service error and unable to make and receive calls and can’t text.

Before you begin, check and ensure that the date and time settings on your iPhone are correct. The date and time on your phone must be based on your current location’s time zone because this is among the requisites for network-related services to work as intended. For example, time stamps for call logs and SMS received on the device are based on real-time date and time. Thus, it’s recommended to set the iPhone’s date and time to automatic. That way, it will be updated based on the current location’s timezone.

Another thing to consider checking beforehand is your account status. No reception, can’t make calls or can’t text error may have something to do with the status of your account. Talk to your service provider to check and ensure that your account and network services are active. If your iPhone still prompts No service error, then here are your next options.

First solution: Reboot your iPhone/soft reset.

A simple reboot can do a lot of good things to your iPhone. Aside from dumping junk files from its memory, it also corrects minor software errors and fixes common symptoms tied to random app glitches and firmware crashes. Network-related errors that are caused by minor system crashes including No service error, no reception, can’t make calls or can’t text can also be remedied by a reboot. Thus, this is one of the first recommended solutions you should to try on.

Restarting or performing a soft reset may vary depending on the iPhone model. If you’re using an iphone x, XS, XS Max, or XR, follow these steps to soft reset:

  2. Drag the slider to power off your iPhone completely.

  1. Press and hold the Top or Side button until the Power off slider appears.
  2. Drag the slider to power off the phone completely.
  3. After about 30 seconds, press and hold the Top or Side button again to turn the phone back on.

Allow your device to finish booting up and gets to the Home screen. Then see if the No service error is gone.

Second solution: Reinstall your SIM card.

Errors related to cellular or network including No service error on the iPhone can also be attributed to a bad SIM card in use. Your iPhone may be having trouble reading the SIM card or the SIM card system might have crashes. This therefore yields to a No service error or no reception problem. To rule this out, reinstalling the SIM card on your iPhone is recommended. By “reinstalling” means that you will have to remove and then re-insert the SIM card on your phone. Whenever you’re all set to give it a try, then here’s how it’s properly done:

  4. Remove the tray from the phone.
  5. Then take the SIM card out from the tray. Check and ensure no signs of damage (liquid traces or scratches) to the tray or SIM card itself.
  6. If everything looks good, place the SIM back into the tray in the same orientation before you removed it.
  7. Secure the SIM card in place then push the SIM tray back into the phone.

After ensuring that the tray is locked, turn the phone on and see if the No service error is gone. If it still appears, then you’ve got to try other methods to rule out other causing factors.
