| | Re: Cannot connect new mail
you had a phone with a BES and a BIS account, and, you changed the operator.
If you change the SIM on a phone already activated on a BES, it it not neccessary to reactivate the handheld. just change the SIM.
If you have a BIS account on a phone, and change the provider you have to delete the email account the the providers blackberry portal, and, also tell your old operator to remove the handheld from his system. Afterwards you should be able to add a new BIS account at the new operators BIS portal.
Restoring the phone from the backup might restore the contents of the inbox etc., but will not enable the BB to receive mail.
