The phone is blacklisted by the network. You will need to call them to remove it from the blacklist, the phone will not work otherwise.

The SIM card will need to be replaced. Contact your cellular service provider and request a new one.
Note: Some Pay-As-You-Go type phones like Net 10 have the SIM card flashed when the phones operating system is first installed. As such, the SIM cannot be transferred to another (Net 10) phone - for example.

If this is the case, you may be better off purchasing a new phone to keep from experiencing the headache of replacing a SIM in a Pay-As-You-Go phone with propriatory software.

I want my tracfone activated.

Select "Activate Phone" from our website and follow the instructions to Activate your TracFone.

Why does my phone display "SIM card registration failed/Unregistered SIM" or "No Service"?
When your TracFone is turned on you may receive the message "SIM card registration failed", "Unregistered SIM", or "No Service" because your phone has not yet been Activated. Please disregard this message, it will disappear once your phone is Active.

I bought optus prepaid mobile 7 month ago its working well bt suddenely 3 days ago its show unregistered simcard wht i have to do plz help me

If you did not insert a different SIM card in your mobile phone, then the SIM card may have developed a fault or the SIM card has run out of credits and needs to be re-charged.
I suggest you contact Optus to sort out this problem.

My i465 tells me to insert the sim card. why? It is already inserted!

These phones are ****! Absolute ****! I have had my clutch for about 8 months now and have had it in to the nextel store at LEAST 4 times. I continue to get the "Insert Sim" message with no warnings what so ever. They have replaced my sim card like 3 or 4 times and they even replaced my phone once. I am currently having this issue now and plan to go back to nextel and give them a piece of my mind. These phones were also NOT built for texting. They are slow in receiving/sending messages and they lag behind while you are typing a message. I am very unhappy with the Clutch.
