Well after much deliberation, I caved in and upgraded the iPad Air 1. I've got a cellular iPad Pro 9.7, it's a beast! I was just wondering if anyone else had trouble getting the sim in? The tray just didn't seem to want to pop out and I was worried about using too much force on it! I got it out in the end and was it seems fine, sims in and it works. Also checked it came back out again and it did! Just curious if I'm the only one who had problems, perhaps I was a little scared! Lol!
