Sim contacts may be dirty, either on the card or phone.
remove sim card and GENTLY rub a pencil eraser on the contacts to clean, then test. If you can access the contacts on the phone, do likewise. If not, then you'll have to use an Ether based cleaner, Like electrical parts spray ( available from your local auto parts store) .
be careful not to spray too much into the phone, as once the spray gets inside it takes longer to evaporate. You can counter the time by using compressed air to speed drying of the phone interior without taking it apart.
Hope this helps!!

I'm not sure what the question is you are asking concerning a "sim card" but if it's How to put a SIM card in your cell phone you need a pin to put in the hole and it will pop open, However if your question is that your phone keeps telling you to insert a SIM card then you need to turn off your phone first and then go into the place where it's at and remove the SIM card and then put it back in and then turn your phone back on.

Bend the paperclip so one side is pointed out.

Press the small indent on the SIM cover at the bottom of the phone.

This causes the SIM tray to pop out.

Place the SIM card in the tray with the writing facing up.

Insert the tray back into the phone and wait for the phone to reboot.

Apple iPhone 4 uses a Micro SIM which is 15 mm × 12 mm in size while the standard Mini SIM is 25 mm × 15 mm in size. To insert a SIM in iPhone 4, follow the steps below:

1. Take a simple paper clip and make it straight.
2. Check the right side of your iPhone 4 to locate the SIM tray on the Right side of the iPhone.
3. Insert the pin into the small hole and push it slightly until the tray pops-out. Now pull out the Sim card tray with your hands.

First, make sure you have the SIM inserted in the phone correctly. If you do - and the phone still doesn't recognize the SIM card - you may need to replace the SIM card.

This is a common problem with some phones especially when the SIM has been transferred from one phone to another.

Just about the only way to correct it is to replace the SIM card with a new one.

You can purchase one on eBay for a few dollars instead of paying $25 at a retail outlet. Once you receive it, carefully pop it out of the card it is attached to and correctly insert it into your phone.

Put in your battery and turn your phone ON. You should see a 'No Service' message on the screen. If you do, then your phone can now recognize the new SIM card.

Look on the larger card you removed the SIM from and get the SIM number from the card. Then call your service provider and inform them you have replaced a defective SIM card with a new one in your phone. Give them the new SIM card number and in less than 1-minute your phone will be working again.

When it does, the message on the screen will change from 'No Service' to the name of your cellular provider.

it might b sending a service mgs.....reset ur phone mgs setings

try taking out both cards and popping the battery on the phone.

Wait a few minutes and then turn the phone on with no card in it.

Turn it back off when it says no card found and insert the newer card and power it back up.

It seemed to keep a memory of the blank card.

To insert the SIM, insert the end of a small thin paper clip into the hole on the SIM tray.

Press firmly and push it straight in until the tray pops out.
