My Phone Number unknown

[Guest Camobat]

Hi All

Can anyone hlep me with this issue :mellow:

i have just moved to GiffGaff network , and if you go to settings about phone "MY PHONE NUMBER IS UNKNOWN " i think be cause the Sim doesnt contain the number it doesnt show up in status

i have just tried My Phone Number by Lytsing ( marketplace app ) no joy !!

(ZTE Skate- SKatie 2.4 by Ceco )

I have attached screenshot of issue , any help would be great ! :D

Hi

I get that as well, but if you dial *#100#

you will get your number in a popup box.
