Why doesn't data always work

If you see “No Network” or “Searching” on your iPhone or iPad

If your iPhone or iPad (Wi-Fi + Cellular) says No Network or Searching, or you can't connect to a cellular network or use cellular data, follow these steps:

Check network coverage area

Make sure you are in an area with cellular network coverage. Then do the following:

  • To turn cellular data on or off, go to Settings, then tap Cellular Network or Cellular Data. If you're using an iPad, you'll see Settings> Cellular Data.
  • If you travel internationally, make sure your device is set up for data roaming. Go to Settings> Mobile Network> Data Options> Data Roaming.

Restart the iPhone or iPad

Check whether the network operator settings have been updated

Proceed as follows to manually search for and install the update of the network operator settings:

  1. Make sure your device is connected to a Wi-Fi or cellular network.
  2. Tap Settings> General> About. If an update is available, an option to update the carrier settings is displayed.
  3. To see the version of the carrier settings installed on your device, go to Settings> General> About. The relevant information can be found next to "Network operator".

When you insert a new SIM card into the iPhone or iPad, you need to load the carrier settings for that new carrier.

Remove the SIM card

After removing the SIM card, reinsert it. You may need to contact your wireless service provider in the following cases:

  • If the SIM card is damaged or does not fit in the SIM slot, please contact your wireless service provider for a new SIM card.
  • If you originally used your SIM card on another device, check with your wireless service provider to see if the SIM card can be used with an iPhone or iPad.

You can find more information on how to remove your SIM card here.

Reset your network settings.

Go to Settings> General> Reset> Network Settings. This will also reset all previously used WLANs and passwords, mobile network settings and VPN / APN settings.

Contact mobile operator

Problems with the carrier or your account can affect the service. Contact your wireless service provider to make sure that:

  • your account is active and there are no arrears.
  • your area is not affected by outages.
  • Your device can receive mobile services and has the correct data plan.

Only your mobile operator has access to your account and can manage it. If you need help finding your carrier's site, see the carrier support article or use an online search engine.
