Hello,
I bought an Xperia Z3 Compact on December 10th 2014. I live in Italy and I use Vodafone as my daily carrier.
I got a replacement nano SIM card with LtE capabilities just to get the phone in the new, fast network. The problem that I am experiencing is that since about January 13th 2015 I have got some problems with the data connection in 3G mode.
On that day I was using my phone normally, then I tried to send a Text with WhatsApp and the phone stuck with the little clock icon in the lower corner of the message's bubble. I thought that it was a temporary glitch of the network but I'm not so sure about that.
I live in a little town where the coverage is really good, either in LTE and 3G mode. I tend to use 3G because it uses less battery and it does not affect my 4G data plan.
Th issue is that if I do a speedtest when I'm experiencing that network glitch I get a ping that is higher than 2000ms, but with really good download speeds.
The problem is that I believe that it isn't a network issue because my mother has an HtC One S phone and runs vodafone without problems even when I'm having the glitch.
I tried to reset the phone to factory settings but it didn't help.
In LTE/4G I don't experience that issue. In fact I think that if it is a phone's problem it must be software related because the antenna works fine.
If it does not resolve I will try to contact Vodsfone ad then I will send my phone to the assistance service if Vodafone tell me that the issue is not on their network.
Thanks in advance for your help.
Simone
