  • Issues with your carrier or account

    If the carrier suspects you have a fraudulent activity or your device is blocked from receiving cellular services, it will affect your service.
  • SIM card Damage

    If your SIM card is damaged in some way, it may not be able to access your network carrier and as a result, your iPhone may be unable to find.
  • Poor Network

    It is also possible that there is poor network coverage where you are. Your network carrier may not have covered all areas hence your iPhone may be unable to connect in certain areas.
  • Software Problem

  • Check Cellular Data Settings: You may also need to check your cellular data settings to make sure they are not causing the connectivity error. Begin by checking to ensure that cellular data is set to "ON" You can do that by going to Settings > Cellular > Cellular Data.
