C2 01 doesnt accept the sim card, the pops out the "sim registration failed' message. the sim card is just fine, it works perfectly on other cell phones

1.Bad SIM -if it wasn't unlocked you'd get a message asking you to enter a PIN.Get the pin from an online vendor like .
2.With a warning that you have 10 attempts to enter the correct PIN code or it could be locked forever ,if you don't get that message it's "mostly likely" unlocked.BUT find a phone with a known working SIM and see if it will work and connect to the network.
3.May be a hardware problem try flashing with a custom rom.
4..This has to be a problem with the SIM card slot, which is soldered down to the logic board. It's possible that it's a mechanical problem , you might be able to open it up and discover that the card-detect switch is failing to detect SIM card insertion.
5.The os system has been updated and your phone is not being recognized with the right settings , this happened after a update a year or two ago..

I had bought nokia E71 from nokia store and now after 1 odd month it has started showing sim card registration failed followed by insert sim card message on white screen...what could be the problem and i...

Sim card registration failure means that the card in the phone is not being recognized by the service provider as a valid or current account. The service provider is denying service based on the sim card that you are trying to use in your phone. If you have a current and valid account with your cell phone provider then you need to contact them to remedy the problem because something in the registration process has failed. They need to update and/or correct their records to link your account to the sim card in your phone so that your service will work.

Phone says sim card registration has failed

When the message sim card registration failed comes up it is usually as a result of one of 2 things the first being that the phone has not recognized the sim card due to an improper fixing or the sim card has become faulty. Simply try the sim on a different mobile device to determine if the sim card is still good.

I can't use my Nok 5230. I get a message: SIM card registration failed. I tried the SIM in a different phone and it's worked and I tried an other SIM in the Nok 5230 and didn't worked too. What can I...

this is most common when your phone is a branded phone that has been unlocked(branded being it was made to work with a particular network but was unlocked and can now partially work with other networks). in this case, the phone may find it difficult to recognize your sim card, the way the phone is made is in such a way that when a sim card of the network it is branded to is inserted, it would register it straight away but in a situation where it does not recognize the sim card, it is unable to register it. this brings about the sim registration failed.
sometimes you may lose service on your phone too depending on the level on your sim card.
if it happens that the mobile phone was not branded to any network before, then you have to change your sim card to a more developed one(maybe you get a replacement from your network provider because they produce sim cards the previous ones may not have some features or have a high level of attention and therefore needs to be changed with a more recent one)
hope this helped you? please rate

Factory resetting the phone will do absolutely nothing with this problem

There are 3 causes of Sim Card Registration Failed, when you first turn on the phone, the sim card attempts to connect to the network if it can not do this it gives a message like Sim Card Registration failed.

1, The sim card is turned off (is it Orange) if you have had the sim card for a while and it hasnt been used they will turn it off, you need to contact them from another phone to get it turned on or get a new sim card.

2, The phone has a hardware reception problem, when it attempts to register itself with the network it can not... There is a reception problem and it requires repairs, this isnt really an easy diy job on this handset.

3, The phone is blocked, i.e reported lost or stolen. Some networks when a phone is reported will allow it to get reception but will not let it make calls, however other networks will not give it reception at all and hence you get a Sim Card Registration failed message.

I hope this helps, these are the causes of the message.
