Xperia S Mobile Data Network Connection Not Working

[#1]

I have been experiencing this for months already. I am honestly not sure how and when this problem started but I am sure that when I bought this phone last March/April 2012, my data  network was working. And then an update became available (not the ICS update), problems started to happen. Data network became limited to certain apps only. And then the ICS update happened. 98% if the time, the data network never worked. I only get notifications, for example from Facebook,  but when I click on the notification, it always never gets to show me what the notification was about.

I asked my provider about this a couple of times so they can check if their services are running properly and they always confirmed that this service on my account is working well. And I doubt they will disable this or what since I've been using this service since forever! Unless there are any problems with their services, which I am not aware of...

Now, contacting Sony directly seems to be my next (if not my last) best option.

Help, anyone? I'd like to be able to use all features of my phone everywhere and anytime but this problem is preventing me to do so. I love my phone but so far, it's not loving me back.

Would appreciate any assistance on this.

Thanks.

no problem :smileyhappy:, just make sure you don't drain your batteries suring the internet with your device.

I've been searching a lot regarding this problem, and I though my phone is defective. I am having the same problems after the upgrade, my basic applications that worked well with GB such as yahoomail, messenger and almost all of my games aren't working (because they require connection) when I use 3G connection. I am a prepaid user and used to buy data for a month (250GB) as I am using wifi at home. Skype is the only working communication application right now. I would like to go back to Gingerbread, the time when I used to enjoy all my applications. I hope Sony would resolve this soon. I am very unhappy with my phone right now

HI .. i SOLVED the problem

check the pic attached.......

when i bought the phone, i was using SIM card number 1 on ICS 4.0.4 .. 3g was working with full coverage

after upgrading to JB 4.1.2, SIM card number 1 is not working any more because it's not compatible with JB 4.1.2 .. so 3G was not working anymore, and there was no 3G coverage at all

i went to the GSM company, and they gave me SIM card number 2, which is compatible with JB 4.1.2

and now 3G line is working again with full coverage.. like charm

Hi,

I have an issue with GPRS connection on my Xperia SL.It works only in one of rooms in my house but not else where.I have checked the signal strength and its full everywhere in the house.My brother has HTC explorer and my cousin has Samsung S3 and GPRS works for them everywhere in the house.(all 3 of us use same network service provider-Airtel INDIA).

I have also seen that It doesnt work in some places outside too.Clearly appears to be problem with Xperia SL.I have exhausted all options.(settings reset,APN reset,re downloaded the settings but none helped).Let me know if anyone else is facing this problem and has any solution for this.

Thanks,

Ashwin
