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

Odd connection issue

It started yesterday and I don't know why. Go to check my weather, hit update and after about 10 seconds I get a bubble telling me that an unknown connection error ocurred and to try again later. I can make phone calls, send and receive texts, but can't check my weather. If I soft reset it works fine. Today, go to check my weather again and same problem. Been making phone calls and texting all morning without issue. Soft reset and again it works fine. Obviously, something is going wrong with my data connection over time, but what could cause it to just shut down completely requiring a soft reset to fix?

More weirdness. I tried manually turning on my data connection in the Connection Manager and as quickly as I turn it on it turns itself off. WTF! I haven't done/added anything to the phone in a week. Is this something on AT$T's end, could they be blocking me from using data for some reason?
About 2 weeks ago I did some regedit to have the data connection turn off automatically after 5 mins of non-use. It was working fine after that and anytime it needed a data connection it would make it. I don't remember where the setting was to change it back, but I doubt this is the problem because this issue just started yesterday.

I'm on AT&T also, on the new leaked ROM, and I have exactly the same issue. It started about 2-3 weeks ago, and I noticed the connection drops overnight (during the day I have no problems), and it'll only come back after restart or reset. I think it's AT&T's network...

Maybe they work on improving their towers and network lol

T-Mobile does that also.
i get a Could not coonect bubble,and have to manualy enable my data conection.If you guys are Tethering our providers automaticly drop our priority level...Unlimited my ass,they tried to cap me at Edge speed and all i had to do was disable/enable the data conection to blast 3g...

I found the problem, but I still don't know what caused it. I'm leaning towards something done on AT$T's end. I have always had my phone configured to use the AT$T ISP in network properties. Apparently, it no longer likes this setting. Switched back to MediaNet and all is working just fine. Problem is that when I first got the phone I did speed tests using both settings and AT$T ISP was faster, so that's why I set it that way. I can't test it now because it won't stay connected with that setting. Can AT$T block users from a particular connection? I don't tether and the most data I've ever used was 280mb last month. Hardly a reason to block me.

I'm not thethering either, my usage is roughly 600 MB/mo and my network is already set to MediaNet. This problem started recently, didn't have it before.

Looks like it is something going on with AT$T. A number of my friends from different states have reported issues over the past 2 weeks with several having severe connection issues the past few days. These are people on varying devices including iPhones, Blackberrys and smartphones. I hope it is due to AT$T finally upgrading their network and not overload from all the new iPhone users and abusive tetherers.

[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] Network Mystery (to me anyway)

Sorry if I'm stepping on another post here - but any help would be appreciated....
I have a Tmob M8. 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?

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?
