blocked blackberry bold 9900

I have a blackberry bold 9900 and it has been barred by its network provider as i thought i lost it and claimed off insurance and i think the IMEI has been blocked i cannot make or recieve any calls on it however as i have relocated to the UAE it works perfectly with a UAE sim card. is there anything i can do in order for me to use it when i get back to the UK? someone please help

No, if the IMEI is blacklisted you should sell it to a user from a country where it can work.

so you are using a stolen phone then, since the insurance company now is the legal owner of the phone.
