I have a Nokia 6802, having gone through two 6600's (same battery on these two phones). When I bought the 6802 on eBay a little over a year ago in summer 2007, it either came with two batteries, or I had two from previous phones. I also got the "sim card registration failed" with this new phone, but -- oddly enough -- when I switched batteries, the problem went away. It was only with _one_ of my three batteries that I had the problem.

Now, my last "good" battery is wearing out, so I bought two more on Amazon from a 3rd party seller. They arrived today, and the first one I put in worked fine at first, but after 5-10 minutes, it gave me the same SIM error, just as I had seen happen with that other "bad" battery. Why is it battery-related? Seems awfully odd.

Well, my suspicion is that it's because on this phone, the sim card fits into a little hinged receiver that is held down against the contacts when the battery is inserted. I tried pressing on the battery and its cover when this came up a year ago, but no luck. Since I had two working batteries, I don't think I ever bothered with trying to resolve it any other way, but I would consider some paper shims or something else to make sure the sim is pressed firmly against the contacts on the phone. I don't know the internal layout of the 6300 with regard to SIM and battery; possibly similar?

I'm just now trying the second of my two new batteries that I got today. Phone booted fine; we'll see how long it stays up.

FYI -- these batteries are model BL-5C, 3.7V, 850mAh(?), Li-ion.

You will need to unlock your phone so that you can use other carrier's sim cards.
simply ring up Telia and ask them to unlock your phone. they should be able to take you step by step and provide you with a code that will unlock your phone. however there may be conditions that are linked to unlocking your phone. in australia, there you usually have to be using the carrier for 6mths in order to unlock it, or pay a fee.
good luck

Nokia 6300 sim card registration failed

You could try cleaning the contacts on your sim card using an eraser and see if that helps.. If it is still not working try using your sim in another phone, if your sim is working 100% in other phone then it is either the imei of the phone is corrupted or the phone is block by the provider!!!

The phone keeps displaying sim card registration failed on phone

The sim card holder is too loose on a lot of new Nokia phones. Place some folded paper (3,4,5,6 times) between the sim card and the sim card holder. It should fix it. I have an E65 and had this problems for two days after buying it. Since I fixed it 3 months ago, never had this problem again. Hope it works for you too.

Nokia 6300

SIM Card Registration failed, means your SIM card serial number does not exist in your SIM provider's Server.

Generally when a SIM not used for a long period (About 6 months or any fix duration by SIM provider), the company remove that SIM card serial number from server.
In some cases if your SIM is new then it might not be activated by company, so you can ask regarding this the customer care of your SIM provoider.

Sim registration failed

most of this nokia phone(the old ones) do often experience such problem due to it's constant falling on the ground.
in such cases after restarting the phone the problem should be corrected for a while...............using a NEW sim card and practically the one of a network with the strongest signal does in most cases rectifies the problem a bit.
all the same i would ask you to send it to a phone technician for more help.
good luck
