This could be due to insufficient battery charge. Try taking out the battery and cleaning the contacts then put the phone on charge for at least 3 hours. Then try switching the phone on using the correct button as stated in the manual. If this not resolve the problem then try using another battery or charger (if available) which is suitable for this phone.

Otherwise call us on 089 420 0000 or 1749 from your Tesco Mobile (calls cost 30c per call) or on 089 420 0000 from another phone (costs from other providers will vary) as the phone, battery or charger could be at fault.

You or someone else may have entered your handset PIN incorrectly three times. Don't touch the keypad or press any numbers or you may permanently block your mobile.

You will need your PUK code to unlock your phone. When you first bought your Tesco Mobile phone or SIM card, you would have received details of your PUK. If you no longer have that then call Customer Care on 089 420 0000 or 1749 from your Tesco Mobile (30c per call) or on 089 420 0000 from any other phone (costs from other providers will vary. Calls may be recorded.). Please have your mobile number ready for your unblocking code.

If you have entered your PUK code incorrectly more than 10 times, your SIM card may be permanently blocked. Please give us a call on 089 420 0000 or 1749 from your Tesco Mobile (calls cost 30c per call) or on 089 420 0000 from another phone (costs from other providers will vary) as the phone and we will arrange to send you out a replacement SIM card.

There could be several reasons:

• Have you run out of credit?
• Have you got network coverage? (this will be indicated on the phone’s display)
• Is your battery charged?
• Have you entered the full area code – even for local numbers?

If you have checked all of the above and you are still unable to make a call give us a call on 089 420 0000 or 1749 from your Tesco Mobile (calls cost 30c per call) or on 089 420 0000 from another phone (costs from other providers will vary) as the phone and we will talk through the problem with you.

The first thing to check is that you have got network coverage. If you haven't got coverage your phone will often display a message on screen to inform you that your network is unavailable.

Secondly check that your battery is charged, otherwise you may not be able to receive incoming calls as the phone will not have enough power. It's a good idea to let your battery completely run out every so often before recharging, it will keep it working better for longer.

You have lost your connection to the network. You may be in a place where the signal is blocked such as a tunnel or between tall buildings. Or you may be outside of the network coverage area. Try again somewhere else.

Make sure you SIM card is correctly fitted. If it is, then call Customer Care on 089 420 0000 or 1749 from your Tesco Mobile or on 089 420 0000 from any other phone.

Your previous network may have locked the phone. You will need to give them a call to unlock it.
