Few Carrier (Cellular Service Provider) does not provide Carrier Settings in full but they offer APN settings for example

  • Google FI which has APN to be entered manually as h2g2
  • MTN Ghana which provides APN pin to be updated manually as the internet
  • BSNL in India which provides APN pin to be updated manually as bsnlnet (Watch teh GIF below)


Settings > Mobile Data > APN [under Mobile Data APN] enter the APN pin


View and edit your APN settings

If your carrier allows it, you can view your APN settings in one of the following locations: Settings > Cellular > Cellular Data Options > Cellular Network. Settings> Mobile Data > Mobile Data Options > Mobile Data Network.


View and edit your Access Point Name (APN) on your iPhone ...




Use the APN pin based on your carrier. Ask them (Your Carrrier) or search using any search engine.

I too had the similar issue on my iPhone 6 after updating the iOS, tried all the possible solutions. Airplane mode On/Off, removed the SIM and put it back in, reset network settings, Power On/Off but nothing helped. The only solution that fixed my problem was to restore the iPhone via iTunes. Did that today and now got the cellular network and phone is working perfectly fine. Make sure you take a full backup before proceeding with the restore option.
