phone: Samsung Galaxy Ace 3 (gt-s7272) (rooted)
From the moment that I have bought my phone the speed of internet via mobile data is so weak; other phones in the same location as mine can use the same APN settings without any problem and their net speed is good. But the strange thing about my phone is that I have to turn-on and off mobile data now and then(after for example 10 minutes) to prevent internet speed from dying! after re enabling mobile data net speed is good but as I said just for nearly 10 minutes and I had to turn-on and off mobile data again!
any idea why it is so and how to resolve it?
