Windows 10: Can the Microsoft Administration change a current landline number to a mobile, so text...

I am simply wondering if Microsoft Administrators can edit in a mobile number to replace a current landline number, so that text security can become workable?I have a friend with a Bitlocker key being requested but signing in to her account on another device gives her security telephone number in her account as her landline, which cannot be used to verify and thus obtain the key.So, is my initial question workable?My friend has two other Microsoft accounts, but these are secured with her mobile number, which is fine.I am wondering if she substitutes her landline phone unit with a model that ac

N8 does not recognise my home landline number

I have a contact for my home landline number, and the number is correct (i.e. it works when I call home). The contact also has a picture, and a custom ringtone.



When I phone the N8 from the home number, it doesn't use the custom ringtone, it doesn't show the picture, and when I look in the log, it hasn't recognised the call as coming from my contact, but it has got the correct phone number (proving that I'm not
masking the number on calls from the home landline).



Is there something special I have to do to persuade the N8 to accept UK landline calls, and match them up with my contacts? I've checked my contacts, and only one contains the home landline number, so the N8 is not finding the wrong contact.



My wife's mobile works just fine, so the basic mecanism is OK. I just needto persuade the N8 that 01420555555 = 01420555555 (I changed a few digits, to hide my actual number, of course, otherwise you'd all be phoning me with helpful suggestions, I'm sure).



I'm on Anna, by the way.

 

Microsoft account security has 2 phone numbers How to change one?

Both security phone numbers on my Microsoft account are the same landline. I can't see how to change one to my mobile so I can read text messages. As usual my questions seem to have led me to the wrong place.
