This is a EROM problem. Take you phone to service centre, if they know what they are doing it will only take them about 60 sec to fix it.

I have just found my mobile phone LGCE0168 after losing it 6 months ago. How can I restart the Tesco PAYG sim card


I am wondering if you have tried another sim card in your newly found phone?

In theory there should be no problems just put your sim back in and make calls.

I am wondering If Tesco have changed service provider in the last 6 months? If they have it could explain your problem.
Asda mobile changed provider about a year ago from Vodafone to EE and my phone stopped working because it wasn't an unlocked phone. As it turned out I had to replace my phone for one that was unlocked because it wasn't worth the expense and trouble of having the old one unlocked. The old one still works fine on Vodafone and O2.

Just a thought. Another thought is perhaps it developed a fault while it was lost or maybe someone has been fiddling with it in that time.

There are lots of aftermarket phone shops around with specialists to give advice. The Tesco helpline might be able to help.

Good luck!

Globe sim card PUK CODE?


there is no globe sim card puk code each sim card has it own puk code you need to contact the sim card company you are trying to unlock and give them the number that is on the sim card. if the sim number as been put in wrong 3 times it will be blocked and the only way to unblock it is as said before. they can ask you the last place or number you last phoned to confirm you are the owner of the sim or were you were when the phone was last turned off and on etc so try to remember.

I changed sim card, now they both display ''Insert SIM''


try taking out both cards and popping the battery on the phone.

Wait a few minutes and then turn the phone on with no card in it.

Turn it back off when it says no card found and insert the newer card and power it back up.

It seemed to keep a memory of the blank card.

Security code for 6133


Open phone, don't go to any menus. Dial *#7780# and press green send button. It will say if you would like to restore factory settings and say yes. Then it asks for a code. This is when you put 12345 and then press OK. This should help because it did for me.

GOOD LUCK!!
