Convert DBK to BBB

Converting Sony Ericsson Backups to Blackberry

Unfortunately, a straightforward conversion of Sony Ericsson .dbk backups to the .bbb format used by Blackberry devices is not feasible. A more effective method for transferring contacts involves exporting them from DBK to a CSV file and importing them to your Blackberry device.

Both phones are old and obsolete, and there is no further support.

Simply put, it is impossible to convert DBK to BBB directly.
Thus, there is no so-called dbk to bbb converter or a free online dbk to bbb converter to be found.
