So I've been having multiple issues with my data, for 2 years it's been working great but in the third year my mobile data has been bad, as in it hasn't been working well in school or outside but in my home it's fine because the wifi is there and shows full bars. As for right now it still doesn't work in school the best, I got a new sim and I'm still not sure what the issue is. I got help again back in January or February and one worker said the t mobile sim wasn't under my name which I found strange but now since that had been fixed she said just out airplane mode and turn my data off which I've been working and, still it hasn't worked the best. What should I do to fix the issue ?
