I phone 7 network error

Hi supun18,

Welcome to Apple Support Communities. I understand that you're seeing No Service and Searching in your iPhone status bar where your cellular data signal should be. I know how important it is to stay connected; I'd like to help. I'd recommend using the steps in this resource to troubleshoot this behavior: If you see No Service or Searching on your iPhone or iPad

If you're seeing an "Update Failed" alert in addition to the messages in the status bar, use this resource instead: If you see an Update Failed or Apple Pay Not Available alert after iOS update or restart

Best Regards.

Hi supun18,

Thanks for getting back to us with those details. I'd recommend reaching out to your cellular provider to see if they can offer service for your device.

Alternatively you can select the "Other Asia" option from the following link to locate Authorized Resellers or Authorized Service Providers closest to your country: Find Locations

Best Regards.
