Contact your network for a proper replacement micro SIM. Cut down sims will cause problems so it's always best to use a proper micro SIM.

Re: no sim card detection in nokia lumia 520

You just need to tell the network operator your SIM card has stopped working. It happens from time to time even if you haven't cut it down. I'm not sure about India but new SIM cards in the U.K are all convertible, they come in the standard size but the micro SIM can be popped out if phone takes micro SIM

Is it that your phone is locked to one Network and you are trying a SIM from other Network ?

to help isolate the problem if its the sim or the fone.. you can pop in a known good sim (perhaps of the same network as yours). if it works, its your sim that has a problem. if it doesn't work.. your fone may have a problem.

also check / wipe the sim contacts. make sure the try is inserted properly n snug.

Re: problem of forbidden network...in nokia lumia 520....how to overcome it?

Could you get this "SIM error" problem rectified? If so, could you please share how to go about it? I have similar problem with new Lumia 520 (bought 1 month back). Suddenly call gets dropped and shows SIM error or some times, this message pops up and stays for long time. Is this phone H/w issue? Or SIM issue...I got my new micro SIM obtained from Vodafone store after deactivating earlier mini SIM.

Check if your SIM is working properly on another phone. If it is then there could be a problem with your SIM card holder. Have it checked out at Nokia Care.

Re: no sim card detection in nokia lumia 520

habila - Though you tested the SIM in another phone, it would be a better idea to try another SIM in your Nokia Lumia 520. Preferably get another SIM which is a ready Micro SIM and not one cut from the regular Mini SIM ..

@trulite

As usual, please make sure that your SIM is a proper micro sim and not a mini sim. Also if you can definitely rule out the sim as the cause then you should get the phone checked out for possible hardware defects.

Re: no sim card detection in nokia lumia 520

Hi Adarshkulkarni,

 

Welcome to the forum! :cathappy:

 

Is this for a Lumia 520 as well? Aside from the micro-SIM not being detected, are you getting the same 'forbidden network' error mentioned by some users in this thread? If this is for a 520, are you using a standard micro-SIM card or a cut up regular SIM? Most Lumia phones (excluding the 1520) use standard micro-SIM cards.

 

As suggested by @farby, try using other SIM cards on your phone and see if they'll work. If this won't help, provide us more details about your issue so we can further check for other possible fixes.

 

We'll wait for your response. :cathappy:

Re: no sim card detection in nokia lumia 520

I bought Lumia 520 one year earlier,&my network provider is Vodafone. Suddenly, my Phone started showing a message 'SIM error' or 'Invalid SIM' . Initially i thought its network problem so i rushed to Vodafone Store and Exchanged my old SIM for a Standard Micro SIM, But my Phone still showed the same message. When i inserted my SIM to another cell phone it was perfectly working, and when  tried putting other SIM cards (IDEA and Reliance) in my Nokia Lumia 520 they too showed the same problem. This means there's no Network issue, its the problem with the Handset.! Plz help..! Have attached the screenshot of the message.!
