i have an iPhone 8 on my plan. The mobile data, cellular data, is not working. It appears to be on, showing the bars and within my settings it is ON. My phone is not on airplane mode. I can send “Text Messages” I haven’t tried calling out yet. But my data is not working. I’ve tried shutting it off multiple times, I’ve tried removing the SIM Card and putting it back in. Any help or advice would be great. Thanks.
