AHHHHH I GOT MY NEW PHONE!!!!!!!!

So I got my new phone!!!!!!!!! My carrier is T-Mobile and I'm under my moms plan. I had a iPhone 6 but the touch screen hasn't been working for months. The weird thing is the touch screen worked sometimes but moistly not until recently it didn't work at all. Due to my parents being busy and pushing it off i had no phone. But on friday my mom had a meeting with T-Mobile and throb sorted everything out so all we had to do was come one saturday to transfer everything from my moms new phone to her new phone the iPhone x. So then i got her old phone and logged into my icloud all of that. I didn't have cellular so i said lets switch the sim card from my old phone to my new phone. My dad took both sim cards and said "oh as you can see thgi9s is a smaller sim card" i told my dad he was wrong and he told me that i was wrong. Long story short i was right I switched the sim cards got cellular and i have a working phone. I have the iPhone 7 rose gold!
