Hi I recently changed from an IPhone 5 to an iPhone 6s. On the iPhone 5 I had an app installed for an international bank, and when making transfers etc. I got a code by sms or within the app. On my new phone I've installed the app again and the phone now ask me to update my digital signature by "associate digital signature with this telephone" and when I press activate it comes up with requesting a confirmation code which should be send be SMS. But I never receive this sms, and I think it could be some old data from my iPhone 5 which has been transferred over to my new iPhone 6s? but I cant find out where to see or change this on my iPhone 6s?
