It sounds like you are having trouble connecting to your cellular provider. I recommend these troubleshooting steps to help you resolve the issue named:
- Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
- Turn iPhone off and then on again.
- Remove the SIM card and verify that it's a valid, carrier-manufactured SIM. Also verify that it isn't damaged, worn, or modified. Then reinsert it.
- Check for a carrier-settings update. Connect to a Wi-Fi network. Then tap Settings > General > About. If an update is available, iOS will ask you if you want to install it. If Wi-Fi isn't available, connect your device to iTunes.
- Update your iPhone to the latest version of iOS.
- Reset network settings by tapping Settings > General > Reset > Reset Network Settings. This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
- Restore the iPhone.
If you're outside the United States, please also follow these steps:
- Go to Settings > Carrier > Automatic.
If the phone registers any carrier network, Settings > Carrier will be present. - If the Carrier option is missing in Settings and you're outside of the Unites States, please contact Apple for support and service options.
- Set the option for Automatic to off.
A list of potentially available carriers appears after about two minutes. If the device is locked to a carrier, it may connect only to the carrier network to which it is locked. If the device displays carrier networks, then the device is working as expected. - Set Settings > Carrier > Automatic back to on.
If you're still experiencing No Service issues, contact your carrier to check for any network or account issues that could cause these symptoms.

Aug 19, 2014 9:02 AM in response to sterling rby Keith6,I'm in the UK with an iPhone 4s with the latest iOS and have a similar problem with 3G , the phone has the 3 G icon and shows good signal strength but apps can't load data, I've tried toggling airplane mode and turning off wifi and these sometimes help but I always seem to eventually have to perform a network settings reset , the 3G then works super quick until the next day and of course I have to enter my wifi password every time for my home network.
anyone got any ideas as this is a right pain?
