It is not simlock you simcard reader is not reading properly you either need to clean the contacts on the simreader or take the phone to a mobile service center and have them service the phone for you

To activate your iPhone use iTunes on a PC or a Mac with your sim card inserted on the phone. Set it as a new iPhone, enter your iCloud account and follow the remaining steps. *Internet or Data connection is required.

My samsung corby txt always said to insert my simcard even my sim card is already inserted.. i tried diffrent simcards but still the same.. i try to insert my sim card in different phone and its ok.....


It means that your mobile is locked with particular network..to overcome this problem you have to unlock your mobile..there are many ways of unlocking of that unlocking via codes is the safe and best way of unlocking..you can try unlock codes from your provider or can get it from online providers..one of my friend got unlock code for his mobile from mobile-unlocker and unlocked his mobile and you can too try getting codes from them and get your mobile unlocked safely..but before that check whether unlock codes are available for your country and provider..

Want to change my sim card in my phone , but when i insert the sim card the phone does not recognise it and says to insert sim card


Hello there,
If your phone is not accepting any other sim card, then it means the phone is sim card secured lock or protected, there are some phones that do not accept any other kind of sim card apart from that which they are made for.
For instance a phone made for vodafone purposes cannot accept etisalat sim cards, it will only accept vodafone sim card. Therefore that is what you are facing with the phone.
Take not, if you insert similar kind of sim you were iniially using, it will accept it.
That is why you cannot use another kind of sim on the phone.

My j20i sony ericsson cannot read my sim card..how can I overcome this problem??


Hi,
Is there any error messages appear when you insert the SIM card?.
  • Try to clean the metal surface of Sim card with a piece of clean cloth and try it again
  • Try to insert the Sim card using different phone ( If it works. The problem is the phone)
If you can use the simcard using different phone then the sony erickson you are using is locked up to a particular network. so all you have to do is to call your service provider hotline to request for unlocking of the phone.

My phone is not registering when you insert the sim card?


1. If it is a new sim card wait till the service provider registers the sim.
2. If it was already working previously insert another known working sim card. If same message comes clean the contact points on the cell phone.
3. If above 2 dont work your phone IC is corrupted and you need expert help.

I have a nokia cell phone and when i insert a vodacom sim card it says the sim is not accepted. so is it locked for the sim card or what can you help me?


Three reasons for this:

1) If you have just obtained the phone and have used your own sim card, your phone is more than likely locked to a particular network. That means that it will only work with a sim card that matches that same network. If you try to use a sim card for a different network, the phone will tell you the card is not accepted. You can obtain unlock codes for most cell phones so that any network will operate.

2) The phone, sim card or both are on a lost or stolen list and the phone has been blocked. If this is the case you can do nothing unless you are an expert. My advice would then be to take it to your local police.

3) Or the sim card is faulty or has poor contacts. You can try gently rubbing the gold coloured contacts with a cotton bud.
