how do you change the language settings on the nec e616v back to english?

language settings on the nec e616v phone

How can I find out my own mobile phone number?

I have a second-hand NEC e616v and I am with the network 3G. With Nokia (on Vodafone) there was a network command - *#100# - anything similar for this phone?
BTW. I cannot make calls from this phone (incoming calls only) so I cannot call someone else to display my number.
