I bought a new ipad, the one where you can put a sim card for the internet. i was trying to open the part where you put the sim card in it to activate it and then suddenly the pin that opens the sim card part went in deep and the screen cracked from the inside. i have an iphone and i had another ipad with a sim and this never happened to me. i just bought it maybe 2 months ago so its not old at all and this was maybe my 3rd or 4th time using it. i bought it from paris. i would like to get some answers anf to know what i should do. I still have the receipt and i have a guarantee for a year.

Thank you.
