got the same problem with iPad 4th gen, IOS 7.1.
I tried:
nothing works.
I tried switching the sim between my iPad and two iPad2, one having the same carrier,TRE , and one with VODAFONE. My sim card work flowlessly onto the iPad2 but mine is showing the carrier logo and a normal connection signal (3 - 4 dots) but drops the connection or is very slow.
The speedtest with the iPad2 and my sim card scores between 1.4 - 2.1 mb/s download and 0.7 - 2.0 upload and a PING of 30 to 70 ms
On the other hand my iPad 4th gen hardly get a connection and scores a PING near 200ms, 0.06-0.21 mb/s download 0.03-0.01 mb/s upload (mb/s stay for "megabit per second")
It seems to me there is a software problem.
iPad 4th generation loses 3G antenna constantly
