Frequently asked questions
Why won't the bank change my mobile number over email?

How soon does it take effect?
Often within a day or two after verification.
Can I edit the wording?
Yes. Download the Word file and change anything you like — the layout stays intact. Or print on your own letterhead by choosing "Leave space" under Date, place & style.
