iMessage and Facetime incorrect number
Hi guys, I have an iPhone 6 and I'm running both iMessage and FaceTime. I recently went to the UK and inserted a UK sim card in to my iPhone and still used iMessage and facetime. The problem is my number remained on the UK number and now I have my old sim in but it won't use my regular number (Keeps displaying my UK one). The number in settings > phone is the right one but iMessage and facetime displays the wrong number.
iPhone 6, iOS 9.3.2
