Intermitent network connection

[johanc]

I have an xperia SP and my network is getting disconnected a lot of times more than 10 per hour, thought it was problem with the network but tried again with an xperia z1 and samsung s3 and the network had no problems at all.

What version you are in? Cause 4.1 is famous for network drops... Should move to 4.3 to get stable Wi-Fi connection sacrificing the ram management..

It will be wise to get a brand new SIM card
