iPad Air Wifi+Cellular: No Cellular Data Button
Hi!
I recently recieved an iPad Air Wifi+Cellular (without a SIM card in it) from a family member. After a few days of using it I decided to buy a SIM card (with a mobile internet plan) to use the cellular data network. However, when I inserted the SIM card and loaded a few gigs of mobile surfing on it, nothing happened. And the strange thing is that in Settings, the only alternatives in the first group of options is Airplane mode, Wi-Fi and Bluetooth. In other words, no menu for Cellular Data. So far I've tried restarting the device, re-inserting the SIM card, resetting the network settings, and resetting the entire device. Nothing has worked so far. Any ideas?
Model Number (on the back): A1475
Model Number (in General / About): MD794KS/A
Thanks in advance!
