Hello, asking for my daughter, her phone wont receive calls and she cant place calls


First of all make sure the SIM card is active and you have network signals, secondly try to find out if the fone is kept in offline mode or airplane mode.

If you find everything proper, try to insert the sim in another device and make sure the SIM is working correctly

2.Your mobile is restricted by some network.So try to unlock it.

I need assistance my nokia 6270 is showing no network coverage and i cant dial or receive call,no network signal on the phone..


Hi There,

There are two possible reasons why this is not working.

1). The SIM card that you are using is no longer valid in the system of your mobile provider.

2). Your fone is faulty and does not make contact or recognise your SIM card whether or not it is inserted into the fone.

Saying no sim card inserted in my nokia 6111, but my sim card works in other fones


hi im josh in cebu phils. may i help you? As a mobile phone techinician, Friend i will say that the problem centers on your phone and not on the sim card.
You phone is locked to the network of that SIM or commonly mentioned "not open line" thats why the software or the phone doesn't recognizes the SIM you are using because it is locked. To solve this problem you may go to your network provider and ask for assistance of opening the line of your phone so that you can use any sim cards you wanted. and your phone will now be unlock or "openline".Thats all friend hope i helped you good luck

I can't insert other sim cards from this certain network


Sounds like the phone hasn't been unlocked properly. I had a similar problem and eventually just changed my sim to the original phones network. This solved all problems but i don't know wether this is the full solution to your issue. I tried to help best as though dude.
Cheers.
