I have a Nokia 6230i. One week ago I lost it and reported to my supplier (Cellcom, Israel) about it and got another one from the insurance. Yesterday I found the original one but I can't use it anymore in my network because somehow, my supplier disabled this phone. Now I can use it in other networks(I unlocked it) but not in mine. Is there anything I can do to make my supplier not to identify this particular phone so I would be able to use it again in my network? Thanks
They might have blocked your IMEI, which is unique to your phone and in read-only memory. I'd probably avoid using the old phone all together, as your insurance company might send around the collectors to try to recover their money. I don't think there is any such thing as being truly anonymous to the phone companies, they know where, when and what phone is making every call. The other companies probably allow you to access the network as they don't have an up to date database on reported phones.
