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

Major network access problem

I don't know what happened, but I can no longer access MediaNet. I was using Wifi this morning without issue. I then turned off Wifi and tried to use Skyfire and kept getting "could not connect to isp.cingular" message. Go into settings and MediaNet is my selected network for both settings, so I don't know why programs are trying to connect through isp.cingular. When I go into the Connection Manager and try to manually turn on my data connection nothing happens. If I click on it to bring up the settings all I get is the ActiveSync dialogue (which is below Data Connection in TF3D settings). It appears that changing my connection settings is doing nothing, it is stuck on isp.cingular somewhere and ignoring the fact that MediaNet is selected. I am now without any data connection on my phone!!! I don't tether and I don't use MediaNet much, so I don't think AT$T wouyld have suddenly blocked me. Soft resets do nothing. I really don't want to do a hard reset and lose all my customizations and have to reinstall all my apps. What could be causing this?

Just spent 45 minutes on the phone with AT$T and after first trying to convince me that the issue was my not having a smartphone plan (I politely insisted they were wrong) they conceded that there is an outage problem in my area. Anyone else in SoCal having problems getting on MediaNet today?

If it is trying to use isp.cingular for what ever reason... unless you are paying for a laptop connect plan, that access point name is turned off in your account. MEdia Net connection profile should be using the wap.cingular APN.
First check under the "network management" page. Where it says "Programs that automatically connect to the Internet should connect using" and make sure that is where you are seeing MEdia Net selected. If so, try the "restore proxy" cab in: Start/tools/Proxy Manager/Restore Proxy

OK, I have the exact same issue as of last evening. I am in Miami with a 305 area code. My GPS, Google Maps, eMail are all down. However, I am able to use PIE to get to the internet. My settings are all correct. ATT suggests a hard reset on my device. I do not believe it is an issue with my device and am not going to do a hard reset so that ATT can figure out what is wrong on their end.

I have MediaNet selected in both drop-down boxes, but when I try to do something like update my weather tab or access the internet I get a connection error referring to isp.cingular or it is blank. I don't know how long it has been out because I have push internet disabled and I mostly use Wifi. I just happened to notice it was out this morning. I tried to update the weather tab in TF3D and kept getting connection errors. It did finally update after repeated tries, but not again since. If anyone else is experiencing problems with MediaNet please post your location.

As I said in an earlier post, Miami (305) and having same problems over last 2 days.

My outage issue spontaneously resolved this morning. All data services on the device are now working again. ATT has no explanation but I knew that a hard reset was not going to be the answer.

No such luck for me, I'm afraid.

Oops.
Turns out I am still "down". Wierd thing though. If I have the phone plugged in to the USB at my office desktop, the communication and data issue goes away. If I unplug it, the problem is back.
I tried charging the phone from a wall jack and the data and communication problem still persisted.
This is very odd.

That's because when connected to a PC that has internet connection the phone uses it as a passthrough connection. I created a new connection on the phone using the wap.cingular access point and I have network connection again, but MediaNet is still a no go. AT$T is supposed to call me tonight to try and figure it out. Can't imagine I did anything to mess it up since MediaNet is a preconfigured connection and can not be changed/edited or even deleted.

OK, finally got the word on why I can no longer access MediaNet on my phone. Apparently, AT$T did some server upgrades recently and they now have the means to identify users on regular data plans who are now using smartphones and they block them. I have had a $15 a month unlimited data plan since February 2009 and have been using it first with an LG Incite and now with my Tilt 2, both smartphones. I originally did this by signing up for the data plan while my SIM was still in my RAZR. I guess in order to better serve their iPhone customers AT$T is now going after us casual users and screwing us out of our unlimited data plans by any means available. The joke's on them, though, as I can still access the network using the wap.cingular connection. Looks like I'll be switching providers when my contract is up in January.

Well, that ain't my deal and I don't think it is yours either. With my sons phone I did the same thing as you describe but when ATT discovered it they just charged me full price for the data plan.
In my situation, I spent another hour on the phone with ATT today and they finally kicked me to HTC technical support. HTC is telling me to do a master reset on my phone and just to reinstall my apps and programs. I really don't want to do it but I am not sure I have a choice, unless someone has a better idea.

AT$T can not change any part of your plan without your consent, period. You have a contract and they would be violating it by changing any terms without your permission. This would allow you to cancel your contract without having to pay any early termination fees.
Let me know if a hard reset fixes your problem. I may do it just to see if it fixes mine. What a freaking hassle, though.

whatever the problem is, both ATT and HTC are recommending a hard reset. I am not happy about it but I may have no choice.

I'm tempted to do the same just to see if it works. I can't believe they suddenly cut me off from MediaNet, but not wap.cingular. I think Tech Support is full of it.

Define what you mean by MEdiaNet? Because he MEdiaNet section of at&t's service (IE, the MEdiaNet home page) is only accessible via the wap.cingular APN and proxy enabled.
Sounds more like the proxy is not enabled on your phone, IMO.

well, I did check my proxy and the phone was still giving me data issues.
I cleared the phone and went back to factory settings. I reinstalled GoogleMaps and my pop email. Both worked fine!
I then did a full restore from backup. My problem was back. Although I did not make any changes prior to the phone faulting, something that is installed is interferring with the phones data connections and I will have to eliminate one app at a time to see which it is.

How did you 'check' the proxy settings? And of course, all you did was restore the problem with a backup of corrupted settings.
I may be wrong, but I don't think an app caused this problem.

Well, the proxy was checked with ATT Tech Assistance on the phone. Didn't do anything.
I am now selectively adding apps. I restored my PIM so my contacts and appointments are all back. When I added Pocket Internet Explorer there was a problem and so I removed it. Problem resolved. Just added Skyfire and seems ok. I have added back my SPB stuff (PP, Weather, Wallet, BackUp, MS), GoogleMaps. I don't have any more time to dcik around with this so I am calling it a day and will play with it a bit more over the next couple of days to see if I can narrow down the problem.

just so you know, if you have ANY of your other phones that is NOT a smart phone, you can have them make that your primary phone using the IMEI number on that phone. Then it wont matter what phone you put your sim card in, because the plan rates will have to go by the phones IMEI number they have on file as your PRIMARY phone. I have gone through many supervisors with AT&T, and they confirm (without actually saying so) that as long as they have an IMEI number listed on the account that is NOT a smart phone, then they cannot make you change your data plan. Just FYI. They tried to do it to me, and I made them put my plan back, and it was a grandfathered plan, so it was a little bit of a pain, but I have a old plan, that has earlier nights and weekends, unlimited data, unlimited text, etc, all on a family plan. They thought they were slick, but Im smarter than that.

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.
http://imgur.com/GBhJJEW
--------
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?

Not connected to Mobile Network after being on Wifi?

This has been a frustrating issue I've been having pretty much since starting up my T-mobile service about a month ago.
To start off, my G3 is unrooted and on the latest stock software version, 20e.
I use Wifi calling often because I get 0-1 bars of reception at work. All seems to work well until I go outside and try to make a phonecall over the voice network. I'll have plenty of signal bars, be connected to 4G even, yet when I try to use the phone dialer to make a call it will say "Not connected to Mobile Network." or something along those lines.
I haven't done extensive testing, but I believe the other day I toggled the "Mobile Data" off then back on and was able to make calls.
Has anyone else had this trouble? Is it something possibly to do with Wifi and/or Wifi calling?
I believe I could make a phonecall using Hangouts when I was off of wifi, which tells me that the data part is working, but not the voice network.
I contacted T-mobile support, but they just had me do the "typical" things, like shut down the phone, remove the battery/SIM, start everything back up. And sure enough, it worked after that, but I'd rather not have to restart my phone or toggle stuff to get it to work as it should without any hassle.
Thanks!

My wife has the same problem after the 20E update. Her mobile is stock as well. It did not happen on 20B.

Off the top of my head no. I'll dig around a bit and see what if anything I come up with.,

From the digging I did I can't seem to find any help. The only thing I can think of is to factory reset it thing and see if it helps. I am going to do do it on my wifes phone tonight.

Yeah, that's what I was thinking too... I'm not really in the mood to deal with restoring all of my apps and whatnot, so I'll hold off on the factory reset for now.
If you remember, could you let me know the results? If I know for fair certainty that a wipe will fix the issue, I might do it.
Thanks!

It's a network problem and it is worst on Samsung phones. I recently went and got a new sim card and it seems to have fixed it. I read it is because if you live in a area where there is poor coverage it causes your sim to where out fast.

This started happening before my first month of T-mobile service was even up with a brand new SIM. I'm not saying that it's definitely not a SIM issue, just would seem unlikely that it's worn out that fast.

Mobile out of Network-Tmobile - Android
I;m having the same issue, turned phone off and on, checked Network connections everything looks fine, but now able to receive and send texts or make calls.

Data roaming even when data is disabled

I was recently out of the country so I disabled cellular data and data roaming on my 5X phone. When my T-Mobile bill came, I had data connection charges several times each day. I called T-Mobile and they said they were all application updates. How can my phone connect to mobile data when I turned it off? I've seen posts about the same issue but never saw a solution. If anyone has figured out how to fix this please let me know. Otherwise I'L just get rid of this phone,

There was a similar issue they had on Project Fi, but I don't know if it is related to your issue.
https://productforums.google.com/forum/#!topic/project-fi/5Srj2it4iHg

I think mine is a little different. I dont see LTE on at all so it looks like data is really turned off. I have been on wifi almost all the time and yet every single dAy has a data connection charge. I am back in the US so I dont know how to check if the phone still has an issue.
