So I flashed a rom(samy deluxe) and suddenly i see I can't use mobile internet. I have good signal but still I couldn't use internet. So i did a full wipe and went back to stock rom. Now I still have the same problem. I notice my messaging and calling doesn't also work properly. I can send messages and recieve messages . I can call I can recieve call but sometimes it doesn't . Like someone sent me a message at 10 pm but I recieved it at 3 AM so I was confused. But Mobile Data never never works. I tried flashing a new modem. I tried setting the APN but it just doesnt work. I see the mobile data letter(H+or E) but it just doens't work and I really don't know why.
