data network issue

[loong]

hi fellow Z1 users, I just have my Z1 for two weeks, and now I discovered sometimes it cannot connect to mobile network(3G), it happen when I switch off 3G for a period of time and when I switch it back on it cannot find any signal, I need to restart the phone to get 3G signal back, is it the software or hardware causing this? do I need to turn my Z1 in?
Sorry for any bad language.

There might be an issue with your SIM card, but do repair your phone with either PCC or SUS and double check the APN settings with your carrier or google them

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

before you repair your phone id suggest getting your internet settings from your operator again just to make sure the access points are configured properly.

This might be the first step. go to settings > more> internet settings. 

See if this helps. Also make sure mobile data in that pannel is turned on.

If the phone is having an issue connecting to the network, either its the network itself or your internet settings.

My last phone, Xperia Arc had the same issue, but im very sure it was the network, I would spend most the day at work on WiFi then I would head home, when it switches over, sometimes it wouldnt transfer data on the network.

Flight mode reset the network and it worked fine, but sometimes I lost connected for almost an hour.

But as a past consultant for a service provider, get the settings from your provider first

Hey guys, my problem is magically solved, I don't know what caused this but here's what i did:
Restart the device for couple times since it can't find any 3G signal and then the legendary SOD occur, I reset the device by pressing the power + volume up button as the other Z1 partners suggested in forum and it came back to live but the 3G problem still there, after that I've restarted it for couple more times to get online and suddenly the problem solved, now when I turn on 3G it connects instantly, Amen to that
