I've just switched network from Orange to O2, and the guys from Orange say I can keep my old phone, do whatever I want with it. Lovely. So I try giving it to my sister who's in France, but when I put her SIM card in it says 'insert correct SIM card'. She's with Orange France.
I figured it was something to do with it being a foreign SIM card. However, I tried my new O2 SIM card in the old phone (SE K750i), and it says the same thing. Is that phone now basically dead? Or is there some way to make it work by resetting it or something?

(btw couldn't think where else to put this... settled on Lounge)

The SIM contains some of the data the system uses to authenticate a phone, but other data, such as the phone's electronic serial number and other important bits comes directly from the phone. So you can put a different SIM in a phone, but unless the system is configured to recognize that combination of phone and SIM, it won't do you any good. I couldn't even transfer my old contact stuff into my new phone by swapping the SIM-I had to get the phone store guy to do the transfer with a SIM-to-SIM transfer box.

Some phones are SIM-locked so you can only use SIM-cards from the company you got the phone from. In Germany those are usually the phones you get with a prepaid SIM-card (since you have no contract they force you with the SIM-lock to pay off the phone).

You have to "unlock" the phone.

Bastard phone operators have locked it to a specific card using modified firmware.

Google will turn up detailed instructions and software on how to do so (chances are, it will then also be able to do a bunch of things that it couldn't while it was still locked down). Might have to do it from Windows, though.

Mobile phone companies here regularly lock phones for their contract time - or on prepaid until x amount of prepaid dollars have been spent.

After this time, you can call them up and request an unlock code - which they will provide for you (for free) to unlock the phone for use on any network.

If it is similar where you live, try calling Orange to request the unlock code.

Cool, thanks for the tips. Looks like I've got an expensive paperweight for the moment.

I wish they did that in the US. Makes sense that after my 2 year contract is up I should be able to use the phone with someone else. I unlocked both my tmobile and cingular phones here though so I can switch them and use them abroad.

I've successfully swapped SIMs before.

I thought that the operator should unlock the phone to be able to use a SIM card from another operator after a while. If I remember correctly they should provide you with details on how to do it after one year (maybe two, not sure) if you ask about it. And it should be free to unlock your phone using their services.

if you head to a local market or something you can usually get it done for about £8 or do it online -- what brand is the phone?
