I have a iphone 4 and it constantly goes between 3G and 1x (small x)... its very annoying. what's the fix for this. there's too many replies in the thread to read thru all of it. please advise.
Simply turn your wifi off when you want to use cellular data. With wifi on, the phone is continuously looking for a wifi connection.
I had the same problem for over a week, but only when I was at work. I eventually turned off my LTE and my 3G clicked back on and everything works fine now.
