Question about RIM BlackBerry Curve 8310 Smartphone

Sim Card Invalid

I have been trying relentlessly for hours to find a number of a blackberry customer service number, with no success.

My problem is that my mum went over to London for a holiday, bringing back a brand new blackberry phone which had been used over there without any hassell.
Once the phone got back to Australia I entered my optus sim card, with it only displaying 'invalid sim'.
I tried numerous other sim cards with the same problem occurring.
It seems that it cannot comnnect to the service providers in Australia.
While I understand that this means that the handset is possibly locked to an international service provider (as I have been told numberous times from optus and vodaphone) they have not given me a solution on how to fix it.
I do not know who I ned to get into contact with in London and I still am not sure exactly what the problem is.

What do I do???

It sounds like the device is still locked to the original wireless carrier. What you need to do is have the device unlocked (if it is a GSM BlackBerry) so that it will work with other carriers. There are several vendors that provide cell phone unlocking services. I recommend checking out HorizonWirelessOnline.com.

My sim card invalid


The reason that it's showing that your sim card is invalid is because either the sim card has been deactivated already by your service provider, or the most likely cause is that your RIM BlackBerry Pearl 8100 is locked to another service provider. The only bypass for this would be to unlock your RIM Blackberry, or to subscribe to the service provider the phone is locked with.

Unfortunately you will need to go the AT&T store or call AT&T customer service, your SIM card got corrupt and you will need to have it replaced, good news at least it wont cost you anything.
