How to figure out my phone number

I really wish this phone had something in one of the menus that told me what the phone number associated with it was, then it would be useful to bring to the US while in Boston/Cambridge/Somerville

Update: It seems it is in my contacts, as opposed to my settings. Not where I would put it, but there you go.

OK, so if I bring this barely used but previously activated Nokia on a T-Mobile pay as you go account back into the USA, can I just call up the "add funds" number and expect it to work or are there other hoops to jump through seeing as I haven't touched it in 7 months?

Well, that was almost entirely terrible.
