Hi, this is my first post on here so iim sorry if I use it incorrectly. For the last 7 days my mobile data (or cellular data as it is otherwise called) on my Iphone 5C hasn't been working although it had been working perfectly for a year. I'm running ios 9.0.2 and i've been on this firmware for a while, when I turn on mobile data an "E" appears in the top left of my phone next to the carrier name but if I try to search something in safari it says "Data roaming is turned off. You can enable Data Roaming in the mobile data section of settings" if I turn on Data roaming and retry it says "Safari can't open the page because you are not connected to the internet" also, if I go to Settings>Mobile data>voice and data it says "2G" if I try to enable 3G it won't let me select it, the blue tick just stays on the right side of the 2G option. Safari is turned on in the mobile data section. I have tried resetting network settings, restting all settings, phoning my carrier and they replaced the sim but it didn't solve the issue, turning on airplane mode, turning off SIM PIN and restarting device, I really don't want to update my device or restore it so I was just wondering if there are any other options I could try.
