Hi rx.prabhu,
It sounds like you have two issues that may be related to cellular data - 1) apps close automatically and 2) outgoing calls get disconnected. Without more details about your issues, I would suggest these initial troubleshooting steps:
- Check your coverage area to make sure that you're in an area with cellular network coverage.
- If you can't connect to a cellular network on your iPhone, make sure that cellular data is on in Settings > Cellular*. On your iPad, go to Settings > Cellular Data.
- If you're traveling internationally, make sure that your device is set up for data roaming. Go to Settings > Cellular > Data Roaming.
- Restart your iPhone or iPad.
- Check for a Carrier Settings Update.
- Take out the SIM card and put it back in. If the SIM card is damaged, or doesn't fit in the SIM tray, contact your carrier.
- Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
- If you have another device, see if you can connect your carrier's network with it in that location.
- Contact your carrier to:
- Verify that your account is active and in good standing.
- Make sure there are no outages in your area.
- Check that your device isn't blocked from receiving cellular services and is set up with the right data plan.
- Update your iPhone or iPad to the latest version of iOS.
If you still can't connect to a cellular network, and have confirmed with your carrier that there isn't an issue with your account or network, try restoring your device.
