Cellular data not working even though fully connected
This problem has been going on for months now. My phone is fully connected to my network (lebara) and shows that i have LTE coverage, but won't really work. I can send and receive imessage, but if there are any pictures or videos involved they wont load. I will also receive Messenger notifications, but then i cannot load the messages or send them back! This happens with almost every app; I'll receive a notification for it but nothing loads on it at all. I was on the phone with Lebara for a while and they found no problem with it at all, so im beginning to think its a phone problem. Their records show that i am connected and use small tiny amounts of data. Ive had an XS Max for about a year and 8 months now. This is super frustrating and i've gone in circles now about this. hope someone can help!
