iPhone SE 2020 slow cell service
Hi there. Recently, I've noticed that my iphone se 2020 has been painfully slow whenever I'm not on wifi. I can barely load anything, and most of my apps are so slow to the point that they time out and won't load. I've tried everything I can find to fix the problem, but nothing has worked. My storage isn't anywhere near full and I'm not near the limits of my monthly data. I'm updated to the lastest ios update as well. The only thing I can think of that might be affecting my connection is that my icloud storage is full. I'm in the process of moving pictures to free up space, but I don't see how the two things are related. Does anyone else have this problem or know how to fix it?
iPhone SE, iOS 14
