Hello,Could I get nano sim with my number,because I have new phone and this sim wich I have is too big.my telephone number is XXXXXXXXXX.My adress isXXXXXX

You can do this yourself - see here:
Change my SIM
Choose the "swap" option and pop the required size SIM out of the trio SIM that you get and then activate it as a replacement.
Hope this helps.
