Hi guys

I have an issue with the Google+ on my phone. (Android)

I login to see my profile and it shows me details including my mobile but I cant edit it nor is it correct (missing a digit)

Where do I edit this? is it online or on my phone? I tried on google+ profile but it adds another entry for my mobile (in addition to the one showing already).

I dont know where is info is from.

Could someone please assist?
