SOURCE: phone showing invalid sim

Is it a new handset? If so it will be locked into the network it was intended for, and if you are trying to use your old sim from another network/operator in this new phone, it will not work until you get the phone unlocked.

If you are saying the sim that came with the phone is saying "invalid", then you need to speak to the mobile provider about this.

If you have used the phone successfuly before & this has just started happenning, the only thing I can suggest is to take out the card, make sure the metal contacts on the card & inside the phone are clean, replace it & try again. If still no joy you may have been disconnected by your network.

Hi can u help with my iphone 3g. it is stuck on invalid sim and emergency mode. how can i get this off? and is there a way to unlock a iphone 3g 3.1.3?


Here is what you have to do. Get a friend that is on the same carrier as the sim card that is in your phone.

Next take your sim card out and put a friends (same carrier) sim card in and restore it. When it is done it will still be in emergency mode. When it says invalid sim put your original one back in it and after about 30 seconds it will go back to normal.

This solution just fixed my iphone 3g so this should work.

Best of luck, Michael Proctor

A message pops up saying: Invalid or missing sim card. You can still make emergency calls if your service provider supposrts it. I have a sim card in their but i guess it doesn't read it?? HELP ME PL


Is this phone from the same service provider as your simcard? If not, not all phones are unlocked to work with the sim cards of rival companies. If both the phone and sim card are from the sam company, then you can have the company replace your sim card. They usually do this for free as a courtesy as long as you explain the problem to them. Hope this helps

Emergency calls only


hello sir,
this emergency calls only is seen only when ur SIM is not activated or ur cell phone dosent catches the signal. Well it shows the signal full but thats the FAKE signal.
If ur SIM is activated try the MOBILE NETWORKS in the SETTINGS option  >  Connectivity
U will search for new networks and u will find ur NETWORK Operator

If ur SIM is invalid u wil continue receving the same message  "emergency calls only"
