If you've added a SIM card to your device and you’re seeing this message, you can try one or all of the following:
- Restart your device
- Take your SIM card out, wipe with a clean, dry cloth and re-insert it
- Try the SIM card in another device to ensure it’s the card and not the device that’s faulty
- Ensure your device is not locked to a non-Vodafone network. If your phone is locked, you'll need to contact your current network provider to get it unlocked.
- If you’ve recently activated a replacement SIM, your old SIM will stop working. Try your new SIM card instead.
