Data Connection

I seem to be having some problem with my HSDPA connection on my desire. I'm wih Three UK and I can't tell is it is my network on the phone.
What happened is for some reason it just wont work anywhere I go. For the first few weeks its worked fine and then towards the end of last month they sent me texts saying they would cut my internet off if I carry on using it but I can't see that having anything to do with it as it is a new month.
The phone is rooted and I've flash the new DeFrOsT Rom (2.0a) and it started working again but then when I logged into the Facebook app it stopped working and went to R (also the wholetime I'm connected to a wifi and when I disconnect from wifi I still get the no connection).
I tried uninstalling Facebook and logging out and no luck
I was wondering if anyone had any experience with this or it is happening to them or you know a fix.
I also attached some screenshots of the message I get, I can't actually read the full message as it cuts it off and then when you select it, it just takes you to the homepage.

the R is for roaming
how is the signal strength where you're located?
go into settings -> wireless and networks ->
tell me what roaming settings you have enabled
untick the box to allow data roaming
data roaming will take place when the signal strength is very low and you are therefore using other carrier's networks (this might also incur high data costs!)

Data roaming is disabled and the signal in my area is usually quite good. Also when I go into a city around here or anywhere nothing changes it still sticks on R.
Plus before I started to flash it with roms and rooted it, it would nearly always have HSDPA connection.

so although data roaming is disabled your phone is roaming...
can i ask why it is that 3 told you that they will disable your internet? this seems to be the main problem...
have you tried flashing a different radio?
this will definitely have some change

They sent a text I was reaching/reached my data allowance for the month (so called unlimited =/)
And yeah I've just flashed the new radio that is needed for defrost 2.0a however it did happen before I flashed it.
For some reason it has got proper signal and HSDPA for the time being and as far as I know I did nothing to make it any better.
Got a feeling it will go again but I'll keep you updated.
I'll have to ring three up tomorrow if I can't get it sorted as I'm going on holiday and I'll be screwed with out it,

sounds to me like you have a data cap where if you exceed a certain limit your internet is stopped.
the fact that you are in roaming makes me think that it is a trick so that 3 can charge you large amounts so be careful.
glad the radio update worked for you
let us know if the problem persists
although there's not much we can do unless we know it's been sorted with your provider.

Thanks for the help.
The thing I don't get is the roaming bit as when it says I'm roaming I can make calls and text fine and there is no charge or anything on my bill it just uses normal minutes

honestly it sounds to me like a problem with your provider
does it still say roaming with the new radio?
if it does then phone your provider because they can charge you a large amount for roaming

Three only run a 3G network in the UK. To provide coverage and data connectivity (mainly EDGE) in the areas between their masts they partner with Orange. Your Desire will roam onto the Orange (and possibly now T-Mobile since they merged on Monday) network when it has a weak or no 3G signal. To allow data in these circumstances you must have data when roaming enabled.
There is no additional charge for 3 customers to use data roaming while in the UK. It is part of your monthly bundle. However, please remember to turn data roaming back off when you travel abroad or it'll cost you a fortune!

+1 for the above, roaming is all well and good but of you leave it on when your on holiday youll definately remember it!

Thanks I didn't realise I could use data roaming as when I clicked to enable it it said I may be charged so I didn't bother but now I will as I wont get charged
I was just about to say that the original problem had gone but it's decided to happen again just as I tried to log into ebay and download something from the market. However I think it has started to use data roaming as there is now an R in the signal box but a G next to it where the H would be.
Think I'll be ringing them up today

[Q] Radio 3G issues

This one issue - I will lose data connection even though i have 5 bars - I pop in and out of airplane mode - then have service back. It happens more than a few times a day. My G1 never had this problem. (I don't know if it happens with a voice services)
This issue happens with any program requiring a data connection. Anybody else having this problem - would it be a hardware or software thing? It is not a "deathgrip" thing - since it also happens when its sitting in my car, not in my hand.
Thank you.
Update. Changed battery manager to performance. Noticed that data was only affected. Voice calls still worked. I just want my slacker to work at night.

Well, USA or "other" phone? Reason I ask is because the USA T-Mo version has a wifi calling app that can fiddle with your "preferred network type." At any rate next time it happens you might check that setting for the heck of it. *#*#INFO#*#*, (*#*#4636#*#*). Otherwise maybe your SIM is NFG?

[Q] Losing Network is Making Me Crazy

I've had Background Data set on restricted on a number of apps for several months with no problem. Specifically, Play Store and a few others. Recently, I've started getting error messages when trying to launch Play Store saying that Background Data needs to be enabled. This is even when I'm on both strong network and wifi signals (and also set on network preferred). All of this is intermittent and if I re-enable background data it might - or it might not - connect. Until I reboot.
Also, (and this has nothing to do with background data restriction) when I'm in an area with strong network coverage, if I try to launch a web browser, it will often pop up with a bunch of ISP icons ( ATT, Comcast, etc.) saying that I need a wifi connection. This is outside with no neaby wifi and a strong network signal. And - my wife is standing right next to me with the same phone and none of these issues.
Phone is not rooted and no weird apps.
No problems with voice or text
Did a hard reset. Spent Waaay too many hours on the phone with Tmob. Got a new sim card.
Tmob agreed to send me a replacement but it's on like a twelve day back order.
Anyone have any ideas on what's going on with this phone? - Thanks

Anyone? Please?

Messaging service seems to be an issue for me on Tmo.

No Mobile Data

Hi, its my first post on the Z1C forum.
I just got one yesterday to replace my Nexus 5 and am accounting a few things I need help with since I am new to the xperia line of phones.
So my phone looks like this (for data) however I can't browse anything. I have mobile data enabled, national roaming and preferred network being 4G but nothing is working. With my Nexus 5 my data just worked so I am unsure why this is happening here. I can send texts and make calls just fine. Phone is on lolipop 5.0.2
The wifi signal in my room is terrible and its constantly dropping and when that happens I can't do anything with it.
I am on tesco mobile with a 2GB 4G plan.

Edit: So I looked around I went into mobile network and scanned, found tesco and registered. So I have 3G data now, but 4G isn't registering. Maybe I need to phone up Tesco and ask them.

Or maybe it's just not a 4G mast where you're connecting?

Is problem "no mobile data at all" or "no LTE connection" ?
Can you transfer data on 3G?
If so - check twice if your SIM card is LTE compatible.

I had to adjust the APN on my phone when I first got it as the one it autodetected wasnt correct. Try that out.

Hi so i just got a z1c and this happened to me. I could send and get text/calls even get notifications and updates. I called sony and t-mobile, nether could help me. Then i found a option under "more" in settings to update "Internet settings" find your server and hit ok. Try it out, i hope this helps.

In my case I needed to contact my carrier to enable 4G. Tried it?
Not sent by me.

settings.>>other>>>internet settings>>>download internet and mms settings...
this should do the trick...

Inconsistent Connection
I got my Z1C a few days ago and updated it to Lollipop yesterday. Ever since the update, the phone has been dropping data connection. I don't know what's the initial cause yet but as it stands, in order to get it working again I have to take out the SIM and reinsert it multiple times. I'm watching it carefully tho because it seems to happen whenever I start Candy Crush. Is there anybody else having this experience?

Mobile Data stops working

Hello,
I live in an area (like many of us) there T-mobile service isn't that great. I daily drive through areas with zero service and I have almost no service at my house so we utilize WIFI Calling.
I have been finding for the past few months that when I return to an area of good service (phone showing full bars of 4G or 4G LTE) that I cannot move any cellular data. If I reboot the phone then everything works again for a while. I have tried to toggle into airplane mode and back but this does not help, only a full reboot helps.
Does anyone else get this? Its very annoying to have to reboot the phone when I need to use cellular data. Appreciate some input. Phone is NOT rooted and running the latest available software from T-mobile

It happens all the time for me. I've not been able to figure out why it happens, but I've seen some speculation in other threads where people think it can break when switching between H+, 4G, LTE, etc. Some people have reported that switching to airplane mode and back fixes it, but it doesn't work for me. Only a reboot will fix it for me.
Here is another thread with some discussion on it:
http://forum.xda-developers.com/galaxy-s6-edge/help/mobile-network-data-connection-drops-t3097605

Thanks for the response. I'm not happy to hear it appears to be happening to everyone. I wonder if any of the carriers have reported this to Samsung?
I cleared the cache partition on my phone 2 days ago and I've been good since...that doesn't mean it fixed it but its been a while since I had 2 good days!

THIS HAPPENS TO ME OMG!!! I thought I was going crazy... it happens quite often in NYC where we travel by subway underground... Switching to Airplane mode then back indeed fix it majority of the time, but it doesn't work sometimes...
Also, this happens when i am on Wifi for extended period of time, and then leave WiFi, the phone will show 4G LTE but wont' push any data.
Going into Phone status will show that you have no IP Address...
edit: btw, i've done an exchange with Tmobile, and still happens on the phone, Swapped SIM card as well, doesn't solve the problem. T-Mobile ran diagnosis, and found nothing wrong. I suspect it might be T-Mobile's network configuration...
Also, I can almost 100% reproduce this when I am playing a game that requires periodic connection (like loading acount info), and then playing in the subway while doing data connection between subway station (we have internet at the station, but not in the tunnel) will break my 4G LTE data connection...
