I don't know why not, but the same applies to my UK based one as well - from Germany I have the account and PIN saved with the access number, and 3 speed dials saved on the SIM.

I didn't mean speed dial of the phone keyboard; I meant speed dials set up in the account itself. Thus you don't need to open the phonebook midcall if the complete 3 part number is saved then dialled - eg 08001890116p210xxxxxx65p*5 - some SIMs seem to allow up to 3 up to 32 digit numbers; more would need to be in the phone memory instead (up to 48 characters I think)

In the same way, some callback companies allow setting up of some speed dials. This means it's possible to call home with as little as 3 key presses, one to start the callback, then eg 1#
