Hi Ibby. Did you follow the instructions on activating the reserve tank? I did get your reply saying the option may be removed. I have just checked and the option to activate reserve tank is there. It's number 450 then option 3 after that it's option 2 and finally option three again. If you are still having problems then I'm afraid the only option is to apply credit to the phone. With some NOkia series 40 phones which I believe the Nokia 2610 is you would have to go in to the main menu and then select contacts. The my number would have been in the list of options displayed.
