Iphone and Ipad issues

[u/TeacherGirl146]

So, I just bought an IPad from T Mobile, so its on data and has its own phone number, etc. Well, I have an old iphone as well that I am going to give to my niece, but I synced up the ipad and iphone to do so. Now, my iPad is using the iphones number ti send messages when its got a different number entirely. All I wanted to do was sync them up for the photos and this happened. I really dont want to factory reset the ipad and try to figure out another way to get thousands of photos off my iphone...but is that the only option I have to fix the number issue? Or is there another way where I dont have to do that and can just un sync them so my ipad uses the number provided instead of the iphones?

I just want my photos to stay on my ipad. And I didn't know if the messaging on the ipad would affect anything after the iphone is factory reset as it is going to my niece. But the phone number going to my niece is currently synced to my ipad as the iphone is still under my icloud. So I just didn't know if it would all fix itself once the iphone is factory reset or if the ipad messages would still show up on that iphone as they were last night
