I have just ported my previous number to koodo and everything works fine but in my Android phone settings (in SIM info.) my previous number still appears. I have turned my phone off and turned it back on several times but it is still there!
Sim cards store one number and that number cant be changed. If you still have the old sim card in your phone it will still show that number even if you have ported it. Simply take your old sim card out and this should dissapear.
