Loosing data connection - Sony Xperia ZL

Hey everybody!
In the last weeks I often loose my data connection. I only use 2G-Network because 3G isn't available where I live. Sometimes when I pull my ZL out of my pocket, network strength is good, but there's no data type indicator like G or E. I then have to restart my phone, and suddenly I also get data network, and all missed E-mails are shown (via push).
Sms always is possible, with and without data network. I never turn mobile data off, and I don't use battery optimizers like greenify or sonys stamina mode.
Any idea what might cause this or how I could solve the problem myself?

[Q] DATA connectivity problem with ARC

hi people
i'm noticing a problem with my data/edge/3g connection.
it simply stops working at times .. it just shows data being sent but no data received and my internet doesnt work.
This becomes fine after a reboot but again has a problem after a few hours
Is anyone else facing this problem too with Data connectivity ?
Yes, same problem with my german arc.
I am not facing any problem with data connectivity
same problems here, I found that stopping the WIFI and re enabling it is enough to get it back on track but its still a serious issue.
I don't like finding out I am missing e-mails an hour too late.
I only found it happens when I switch from 2G to 3G with data on.
So my work around is to turn data off first before switching between 2G <-> 3G. After that, turn back the data on.
This only happens to me on WIFI, on 3g everything is fine.
I am thinking about flashing the UK build to see if it helps.
I used to have the same problem with my x10. Data just stopped working randomly. I used to have a widget to turn 3g on/off and when the data stopped working, so did the widget. Was strange, and only a reboot solved it.
I have wifi problems,it sleeps after a while,no sleep is selectet.

same here. wifi works fine. til awhile later (evactly how long i didn't notice. will keep track)
After which no matter how i turn off & on wifi, forget the network & re-enter p/w. even off & on my phone. wifi status "connecting.... disconnected....connecting.... disconnected." will drains off a lot of battery if go unnotice.
i found a cumbersome work around... off the arc wifi & reboot modem/router. then can "obtaining ip address". but thing is, all other devices works fine.
so is it arc's fault? since all others can connect to wifi except arc
or
router's fault? i wasn't doing / changing setting on the arc. just reboot router. but wouldn't it be silly to do this everytime i use wifi on the arc?
so still no fix? sometimes it happens to me a few times during an hour...
Guys maybe this will help you out..
Go to wifi settings, press menu button->select advanced->under wifi sleep policy, set as never sleep
If not set the wifi shuts down to save battery.
And wifi is given more priority over 3g or 2g connectivity, so if you have wifi on you may not have proper connectivity to 2g or 3g
Turn on/off airplane mode, if you can't get a data connection. In a german forum some guys discussed about issues with multi-sim-cards, but I guess it is software related.

i changed my number and sim a couple of days back. with the same provider. my arc after being out of signal cant reconnect to the data network. the phone calls work fine. but the data is giving me problems. im still confused as to why this is happening. whenever i activate and deactivate the airplane mode, data connection comes back alive. could it be a problem with my sim or the phone radio?
edit: oh and i also reflashed my phone via sony ericsson update service, the problems still there.

Same problem here. This is really frustrating.
I dialed *#*#4636#*#* then phone info and pressed menu. Then I selected enable data connection (was disabled previously). The data didnt enable then. I went to settings>mobile network and enabled data from there too. Ever since, no disconnections. I dont know if this procedure or the fact that I tried to seat my sim properly worked, but u may try either. Let me know if this works....
Edit2: the above doesnt work.

I inserted my old fat sim and recreated the situation, the data automatically reconnected. The newer sim that's a microsim is causing the problem.

No phone signal yet can use mobile internet

I've got a strange problem that I cannot solve or find anyone else that has had the same problem.
I recently updated to Minco V4 and since my status bar has been showing no signal and mobile standby shows 100% without signal yet I have mobile data. I cannot make any phone calls but can browse the internet. No amount of rebooting, airplane mode on/off will work. I've also gone back to both stock ICS and JB where the problem still exists.
My network is T-Mobile and it won't let me manually connect to it but the phone will occasionally register when I select automatic although it doesn't correct the fault. Anyone have any ideas what has gone wrong with my phone?
UPDATE: It seems I can only get a phone signal when select 2g T-mobile network only or connecting to T-Mobile orange. If I untick 2g networks and it connects to t-mobile 3g I can't receive or make calls.
Does your Radio and baseband match?
I installed the linked radio from the MiNCO thread after flashing the rom and discovering this issue yet it made no difference.
I got a phone signal momentarily about 15 mins ago which allowed me to make a short phone call to test it. I then accepted the JB system update from Google and now have no phone signal, just data.

Issue with wifi and Mobile data

I got my ZL yesterday applied the international firmware with flashtool everything was working fine, but then i noticed that wifi disconnects randomly all the time. Today when I went to work I tried to test the Mobile connection but it also just shows the "E" "3G" "H,H+" sign like 6 seconds then goes blank and i have no mobile data, could this be a firmware related issue or a hardware one?

For the mobile data, i think it is how the mobile data work, when there is no use of data (downloading, syncing) the sign will disappear to save power consumption. When u need the data it will show the sign back.
For the wifi, sony OS for ZL sometime suffer this low connectivity range. You can try to repair using PC Companion if you want. Before this i'm using Incredible S and suffer wifi connectivity loss frequently, i can't finish any download but when connected to other wifi it has no problem, the solution is to change ur wifi modem channel, then the problem solved.
For sony there is solution by altering your build.prop (in Z forum, i forgot the thread) but some user said that it will drain ur battery quickly. I never test it.

Loosing data connection when turning wifi off

Hi everybody!
I'm using 2G network only because 3G network is very poor in my area. When I turn wifi off when leaving home the data connection isn't restored to mobile network. I can't open websites, read mails or something else. I have to turn on flight mode and off again to restore data connection.
Any idea how to solve this problem?

[Q] No network data connection

Hello all,
I got my P6 for a few days and from time to time I had troubles to connect the data network (2G and 3G).
When I switch the data on, it connects to the network for 1/2 seconde and then it disconnects (the H+ symbol stays on though). Switching the data off and on again only repeats the problem.
Restarting the phone allowed me to finally have a stable connection so far but since this morning it doesn't work anymore. Removing the sim didn't help.
I'm on B125.
Anyone encountered this problem and managed to solve it?
Thanks!
I may have solved the problem.
Use tweakker from the play store to get the exact apn details for your carrier (mine is Base Belgium) and put them in the apn settings.
Since that I can connect the data without any issue (except a new bug: switching to "2g only" make the connection bug again, except if the data is switch off before and switch back on after a dozen of seconds). It seems that it is more like a carrier problem but that creates bugs only with Huawei products (source: internet).
It seems that the P6 is a very capricious phone, I love it but I wouldn't recommend it to anyone which is not an engineer!
