Xperia Z Mobile Data Issue

[ss15ss]

Guys, I've faced this issue before, but it’s been instantly solved by the last update. At that time data is stopped at all. But now its blinking!! Appear and disappear, and the arrows are come and go many times.!! So I can’t browse the internet, is say: connection error. But whatsapp is working fine!! what’s going on? Is it a software issue, shall I wait till I get a new software update?

I'm confused.!! Tell me if you have the same issue.

I have a similar challenge an more. I cant connect via 3G and the data connectivity is intermittent, users of other phones are fine hence the conclusion it must be the phone. Please help

1.

Restart

Restart your phone to turn off all running applications and to free up memory. Press and hold down both the volume up key and the power key for 10 seconds. After your device vibrates three times, release the keys. The device turns off automatically. After the device is turned off, restart your phone.

2.

Update Service

Update your phone for optimum performance and get the latest enhancements. Regardless of whether you have the latest software, it’s a good routine to run the Update Service to improve software stability. Also, if you experience problems with your phone this may be solved by a software update.

Which build number and android version do you currently have? 

Check if your network is experiencing coverage issues?

How old is your SIM card?

Hi Shihs, thank you for response. Actually I did as you said in first part but nothing new ... and about the update service, unfortunately I can not do it right now as I'm using Mac, and no update service software for Mac.

Ninefive, Thank you so much.

It works fine!!

I wasn't think that the issue May regarding the internet configuration as the Whatsapp was working fine. But I tried to get internet & MMS Configuration then its back to normal!!

Guys... Partially, the issue is still when I keep the data running all the day. But thr deference, that its stop "no connection" at all, even for Whatsapp, and the way to let it back is by rebooting the device.!! I think I should do a service update as per Sihstoutch advise, and if its not working,,, I'll move to note3.
