If you receive the error message 'You are not authorized to perform this action' when attempting a transaction, it means you are currently using the TDB Online Info plan, which only allows you to view account statements without transaction privileges.

If you wish to switch to a plan that enables transactions, please contact the bank's call center at 1800-1977 for guidance. If you are abroad, you can check if remote registration is possible by contacting (+976) 7016-1988 or emailing [email protected] using your phone number or email address registered with the bank. Alternatively, you can visit any nearby TDB branch with a valid ID card or passport to register.
