Problems with Vodafone UK - General Topics

This wont affect many of you, but i thought i would post it anyway.
Basically about 1/10 of Vodafone's UK customers will find that thier phones are behaving very unreliably:
The main problems are when someine is calling you it says that you're number doesn't exist and when dialing out it says the same to you, Also sms seem to sometimes get 'lost in the void'.
This is an intermittant problem and is caused by one of thier main switches malfunctioning and isolating itself from the rest of thier network randomly. Each episode will only last a few minutes and there is currently no ETA on when the problem will be fixed, thier engineers are working on it.
Just a heads up.

T-Mobile network disconnection

Hi all,
First time poster, long time lurker I'd just like to say thanks to everyone in the community. You guys rock.
That said, I am having a minor issue with my G1. I have T-Mobile & my phone is SIM unlocked (I don't know if that would make a difference) and currently running JFv1.5 with the latest radio (2.22.19.26I). The problem is that when I disconnect from a wireless network, my data connection to T-Mobile doesn't pick back up. When I go into Call Settings / Network Operators I let it search for networks and sometimes my phone will have to Re-Register on T-Mobile and other times it will say that its already registered to T-Mobile but the data connection still won't work. The only thing I've found to solve that is a reboot of the phone.
This has happened a few random times when I was on RC33 and one of the Haykuro builds but it has become more frequent since I've updated to JFv1.5. Also, I dunno if it helps to mention but I went to a T-Mobile store earlier this week & swapped out the SIM card with a new one and have gotten the same results.
Is anyone else having this problem? I've searched to no avail and was curious. Thanks.
dissconnect
That's just typical crappy T Mobile service have the same prob here since I'm not close to a T Mobile tower when it loses web access it dumps the connection to reconnect
So that's it? I should chock this up to my carrier's signal being ****ty in random places? No one else has had this issue at all?

I am having this issue. Never had a problem until I updated the radio to the latest version
I have had the new radio since the JF build with cupcake. My signal was great until yesterday. It will go from the lowest to highest in the case of the bar. When I reboot my phone it takes much longer to connect to the network. BUT I think my issue is with the fact my market (Columbus, Ohio) was rumored to get 3G by this june. So I am guessing its just TMobile doing the upgrades and whatever they need to do to impliment the 3G rollout.
lately ive been having horrible service. dont know if it has to do with the new LX being released.
Hi,
I am on 5.02h and was having random disconnects on .26 radio.
I went back to .22 saffaire radio and my connection is more stable now.
I am not sure if others have experienced this as well.
I have flashed my phone yesterday with latest from Haykuro with CUPCAKE. (NO SD APPS)
Phone is running a little slower and I started having the issues with the DATA connection.
In the middle of the Web page loading, the phone looses data connection and I am only left with ability to use voice. The data connection comes back in a few minutes and same thing happens as soon as start using the data connection again.
I do not know if previously stable connection at my location all of a sudden became bad or the new build is causing this.......
just to add
Not to dissenlighten people here but t mob has crappy serivce to rural areas. I myself live in brunswick md usa. I have had. 2 bars since I first got this phone with rc30 with constant dumps to no signal all the time when it upgraded to rc33 still the same thing. Then I rooted my to jf rc33 still the same thing. After that I used jf 1.5 and it still craps out. When I go 20 mins to the north to frederick,md I get full bars and no dissconnects so if it where a radio issue there would have been some kinda difference between radio updates. I myself am a ham operator so I should know how radio signal works so when I chock it up to t mobs crappy service I do not do this lightly since the nearest tower is 20 mins either way from me. People need to stop blaming other peoples builds for this issue since the radio update is from google. If I pop a att sim I get full bar and no dissconnects cause the tower they use is closer that's how I know it's a t mob problem not an issue with the radio. Remember troubleshooting is the best way to see where the problem is. Till t mob puts up more towers and fixxes the packet loss to the phone to remedey this then we will all have crappy service which does not seem to be in the near future for anyone.
I had a similar problem when I was on stock RC30. I called in to tech support and they set up a new APN on the phone so it would switch back to EDGE faster if I lose the wifi connection. I would suggest if you're not around stable wifi, just turn it off.

[fixed] Internet problem on sensation?

Hi,
To be clear: Internet is not the app, not over Wifi but over 4G/3G/H etc..
I got my sensation 3 days now and there seems to be a issue with the internet connection.
Mine keeps requesting data but it doesnt get any data back.
Apps like internet browser sometimes work and sometimes they dont (loading google), the weather app says there is no internet connection and manage to sometimes get the actual weather.
I tried restarting it serval times but no success..
Internet does work on my HTC Hero.
Edit:
Found the problem, had to enable data roaming..
Odd thing that it works sometimes without roaming tho..
4G internet issues
I am having the same problem with my internet, though enabling data roaming did not correct my problem. Internet and web based apps work fine over WIFI, but will randomly work over 4G. Is anyone else having a similar issue?

I get a severe lag now and then when connected to 4G - seems to take a while for the connection to initiate. I've tried the "fix" posted in another thread, but that only seemed to resolve the issue temporarily.
It seems like location may have something to do with it as well. The tower closest to my home is where I experience the most issues. Though my G2X or my fiance's vibrant work without any issues.

That could contribute to my issue. I seem to live near a cell dead zone.
Theres a few threads open on this issue. There doesnt seem to be a permanent fix yet, but it is extremely annoying.
Same here, my connection would send data but winter recieve sometimes. Kinda annoying. Hopefully, htc addresses this problem soon.

Same issue - across multiple handsets
Hi, it's been a while since I posted in XDA but this issue has been a regular one with my T-mobile service, across multiple devices. I have searched far and wide for anyone else seeing this exact problem, and finally here you are. I hope this helps other users:
1) Purchased the original myTouch 3G; approx 1 year with zero connectivity issues. Loved it, exceptional for its time.
2) Purchased (upgrade) myTouch 3G Slide at launch. Following 3-5 months saw This issue with outgoing data, but no incoming response. 60/40 the internet would respond or not in any application (web, streaming, podcasts), it was a real crapshoot. Assumed the problem was isolated and performed a few master resets. Zero apps installed and continued to see the same issue. Decided it was either software or radio related and called T-mo for advice. They suggested a replacement unit after standard troubleshooting (re-seat SIM, master reset, check that you have substantial signal).
3) New MT3G Slide, same outcome. Called back. Finally received a reasonable suggestion: get a new (free) SIM from T-mo as the one I currently had was slightly older. Was sure this was the issue as the rep sounded very confident when I explained the situation. Received new SIM!
4) No change, issue persisted. Following day called T-mo and had a 'ticket' escalated to engineering dept. Was assured I would receive a call from eng. dept, but no such luck. Bothered by this whole mess and lacking in answers from T-mo, I sold the Slide and upgraded to the G2X.
5) The issue once again reared its head! If the stars were aligned and I did get In/Out data, it was 11KB/s (90kbps) tops. Ex: 5MB podcast would take 0.5-1.5 min (30-90 sec) to download prior to issue, now 10-15 min. This was with no apps installed, 4 bars of signal, 4G status icon, across multiple geographical locations, and fingers on both hands crossed. It was about this time I suspected that somehow T-mo's network was throttling my account. But, I had never used more than 1GB in a month, and they assured me I was not being throttled. A serious WTF was had
6) Realizing there were bigger problems in the world and finally at wit's end, I returned the G2X and am waiting patiently for my contract to expire in July, while using an old Nokia candybar in the meantime for calls and text only.
7) July: move to new carrier or stay with T-mo (if we can figure out what this issue is). 8 year customer, need internet on a smartphone though.

I am having the same issue, and have gone through the same steps. New Sensation (exchnaged mine twice now) followed by new SIM, tried the *fix* posted, turned on data roaming, and still nothing. I have talked to Tmo several times, and they are supposed to be checking the towers in my area, an engineer is supposed to contact me in up to 72 hours. The Evo 3D comes out before my 14 day return period, so I may just jump ship if this problem persists. Hoping to find a fix though, as this phone is amazing when it's on Wifi

[Q] Android or HTC Wifi Issue

Hi all,
I have searched the threads as best I can so I post this...apologies for the legnth...
It is assumed that the wifi adapter in the Sensation will connect to the strongest signal to give us all the best connection experience possible, however with the proliferation of open wifi signals now on offer in the UK (Openzone and BTFON etc) it is now causing havoc when I don't have BT as an ISP.
The problem:
Currently the priority of the Sensation's wifi radio software seems to be connecting to an open signal first. The strongest is second.
Unlike an alternative Apple product, I haven't found any settings to set a preference for remembered wireless networks and to only apply the other default rules AFTER those preferences.
The Apple product also never connects to a network without the okay from the user. The HTC/Android software connects irrespective. Finally the "forget network" option doesn't work either, as it rescans, picks it up again straight away and because it's "open" connects again.
This always happens in my home as the BTFON signal from next door's BT router is actually stronger at the front of my house that my own router signal from the back. Before anyone says "get another router or position it somewhere else", I can't without spending at least £60+ for a SKY ANYTIME+ wireless receiver (which I refuse to do).
Is there another hidden option for "stock" phones? or perhaps there is a ROM?
What I want it to do is:
1) control which discovered networks I allow my phone to connect to automatically.
2) set a flag to ignore other found wifi networks, regardless of signal strength.
I know these fly in the face of the original idea of the Sensation and HTC, which was to produce a phone that connects to any network as silently and quickly as possible. HTC's "Watch" app and service launched specifically with the Sensation wouldn't have been so great without it.
Has anyone else spotted this with BTFON signals out there or fixed it?
EtA
(Vodafone stock Sensation on 2.3.4)
I've got a stock O2 (2.3.3) Sensation and the Forget Network works with BT Openzone, which is good as I've never been able to get past the "enter your phone number" registration page with BT Openzone. Mine also doesn't automatically try to connect to open networks.
If BT wasn't such a scummy internet provider they wouldn't have their home broadband routers broadcasting as BT Openzone providers.
On stock as well and yes the phone automatically detects the network again after "forgetting" it, but does not auto connect unless I go and tell it to connect again. Not to sure why you're auto connecting after forgetting the network...
You know, this sounds like FUD to me. One post and a non-existent problem no one ever reported.
Forget network works just fine. The phone wont' connect to an open network at random.
If this is real it's got to be be user error.
More than likely just another PEBKAC error...

I'm laughing my socks off at your attempts to belittle me and my issue.
So you both think you are experts do you? How?..based on the number of posts or thanks you have received?
One post of a problem no one has heard of before is how a forum starts off.
Trying to be "clever" with acronyms is childish.
I have posted my issue to HTC and rec'd a sensible response. It is now being looked into.
But then you don't care because its just operator error.
I suppose you never knew that you couldn't input British postal codes into the 'people' app until the bug was spotted. I wonder you raised that first to HtC and then it got fixed...That's right...not you guys either. Too busy belittling members.
Sent from my HTC Sensation Z710e using XDA App
Wish more Vodafone users had posted their experience, as I mentioned my O2 2.3.3 only auto connects to known networks and once connected to openzone I can't get past the page asking for my phone number
As an O2 customer don't you have free Cloud membership?
I used to with my iPhone...Go to McD's and whilst sitting inside connect...I'm sure it's still foc after popping in your phone number.
I thought I could use BTOpenzone as it is offered with Vodafone, but I have to pay seperately otherwise I can't get past the screen you mention either.
I do remember though that even with Cloud coverage my phone would at least download email. It was only browsing that would require passwords etc. Not sure wy this happened really though...seemed to be offering a cherry to tempt buying the cake I suppose.
BTW ...HTC have responded again saying that they are aware there are issues with Wi-Fi connectivity, specifically with baseband (radio) 10.56.9035.00U_10.14.9035.01_M and software 1.45.161.1
They say they will issue "stability" fixes in the next release to vodafoneUK customers (and others UK carriers I presume) in the coming months...

Thanks for this.
Trouble is, that I don't have this application on my phone, although I confess I did at one time but that was two restores ago although it could I suppose have residual data on the SD card. I will check.
I have had a call from HTC Customer Support today as I gave my call experience a bad customer feedback score.
The issue will now be raised further for investigation the developers and they are going to inform me as to when the next update will come out...or at least that is what the guy said...I run a Helpdesk myself at work, so I realise the situation...but we'll see.
HTC have been honest and fair to me in the past so I have good expectations.
I'll report back...
BT Openzone issue
Had this problem myself. If you are on Vodafone then go to the "My Vodafone App", Click the WiFi Finder tab, press the menu key (next to the home button) and click settings. Untick "Enable BT Openzone" and your Sensation will properly "forget" BT Openzones.
Let me know if this helps.
@jengla Thank you very much! This worked perfectly. Been driving me crazy for months

Wifi Calling - Crackle?

I searched everywhere and haven't seen any reports on this.
Does anyone else have serious call quality problems, only when using WIFI calling on T-Mobile? I get a terrible crackle/static fairly often.
I thought at first it was the built-in earpiece but I don't have this problem as soon as I switch off WIFI calling (and call over the 3G network).
What I also thought was interesting, is that when in WIFI calling... I can use my bluetooth headset or speakerphone and have zero interference/cracking sounds.
Let me know if you have any tricks, or if I should get this thing repaired by HTC! Thanks
WiFi Calling Crackling
I'm having the same issues with WiFi calling. I experienced a couple times and thought it might just be a bad connection, but apparently it's more than that. Hopefully the MR update (whenever that is) will address this
Yeah I don't think swapping the handset is going to help this one, hopefully an update comes out soon to address the WIFI calls. And hopefully Skype comes out with one too, because its static as all hell too.
I have the same issue. It was delayed as well. Odd.
Sent from my HTC VLE_U using Tapatalk 2
I am also having that experience with Skype calls and really bad with video calls and GTA 3. Could it be beats integration?
Sent from my HTC VLE_U using XDA
Don't think the beats affect calls since its coming through the earpiece. Guess we're going to need some software updates. T-Mobile mentioned there will be an update to address Wifi Calling battery life, maybe they'll sneak a fix in. I've reported it to T-Mo and HTC... You guys should too.
Overall I'm pretty happy with the phone, minus the pain in the butt power button! Its so flush with the case, it is difficult to press.
yea i also heard about a update rolling out looking forward to it
+1
Getting a slight / medium crackle during conversations on wifi. Crystal clear on GSM.
I get the crackle too, any word on a fix?
Just a reply to say I have the same issue on two One S phones from tmobile. I had to set wifi calling to use cell when available, as opposed to using wifi when available. The crackle was so "sharp" and pronounced that I was about to return my phones because it really sounds like a hardware issue/loose speaker parts in the earpiece! Thankfully, it works great with GSM, so it seems to be software only. And, if I need wifi calling in a pinch, I'm willing to put up with the crackles. If I had to rely on it (due to low signal in my house), it would be very frustrating.
Also on wifi calling sometimes callers could not hear me, or I them. That only happened a couple of times to me, but was a major reason I demoted wifi calling.
By the way, this phone is absolutely amazing! Fast, fast, fast, great screen, great battery, great metal shell... would love to remove Sense because it buries all the Google App integration and favors everything else, but that's a personal opinion.
Skeeboe
Yeah the feel and speed of this phone are just incredible. It just seems like there is some software kinks that need to be worked out.
Another one I've run into recently is YouTube links directing me to the mobile site rather than the native app (which is another problem with the 3 dot menu lol).
I hope they don't rush the first update and work to address some of these quirks.
Yea, I had the crackle issue on my first handset (kept having it randomly reboot) but haven't tried on the new handset since it seems they now have to enable the wifi calling feature on the account and my account is to old to enable it...or so they claim.
Wait so is the wifi calling crackle you t-mobile guys in the States get the same as the crackle I get when using Skype on my One S in the UK?
US t-mobile here. skype's crackle is much worse, impossible to deal with. wi-fi crackle is sporadic and annoying.
I'm completely confused about the whole crackle thing now. I've seen and read about your US T-mobile wifi calling which I now understand and skype crackles a heck of a lot for me. So I assumed that it was a VOIP calling problem but I used Viber to call someone over wifi last night and there was no crackle at all on a 30 minute call. Oh well I won't complain about that, would be nice if skype was working for video calls though
I am experiencing the same issue with WiFi calling too, which is a pain because I primarily make my calls over WiFi. It was so bad on a conference call today I had to switch phones. Anyone know if this is a known issue for T-Mo yet, don't want to call into care if they are already aware of it. Also, out of curiosity does anyone know if this was an issue before the most recent firmware update?
Thanks!
it's hard to say if T-Mo knows about it but they didn't acknowledge anything regarding this issue, only the battery drain related to wi-fi calling. all T-Mo US HTC One's suffer from it.
I have reported it twice to TMO, first time I was told they didn't know about it. The second time a few days later, they were aware of the issue but couldn't tell me if/when they were going to push an update out for the crackle issue. If I were u guys I would report it so they may push something quicker rather than having horrible comments about their flagship ICS device!
Sent from my HTC VLE_U using XDA
Just purchased an HTC One S today.
I talked with T-mobile earlier today and showed them the link to the t-mobile support forum thread created for the Wifi calling quality issues (crackling/delay) on the HTC One S.
They told me that they are aware of the problem and it's a known issue. I didn't press them for a timetable to fix it or anything.
Everyone who's experiencing wifi calling issues should at least take a moment to call in to tech support or chat with a t-mobile tech rep.
We need to make sure they address this quickly. I know a lot of people rely on wifi calling on t-mobile in spotty/bad signal areas. I sure do.

Not able to make/receive calls when connected to LTE - UK EE network.

Network provider is EE UK.
Sorry for the long post​
I’ve had the 1+ since 2014 now, I am rooted and have used various Android 7 and 8 (recently) roms on the device until recently (probably 7 months ago) my 1+ started playing up. I would not get any signal whilst at work; although the building I work is generally poor with mobile signal however I use to get just enough signals to receive a call.
About 7+ months ago this started fading and I would get 0 bars, at first I thought it’s a modem issue so I tried all the different modems and made notes on which one was the best but in the end none of them helped with the situation. I then did what most people do and googled the issue and found that there are lots of other people with similar issue with the oneplus one not working on LTE, many suggested to make sure I visit the engineering menu *#*#4636*#*# and change the connection to LTE/GSM Auto (PRL), however this was already set and yet it was not making any difference. The main issue was not being able to make or receive calls when the device is connected to LTE.
On the odd occasion I was able to make/receive all on LTE when leaving the building but it would be not stable, at times I would get a call but people could not hear me, then sometime I would dial out and the screen would be stuck at “dialing” and nothing would happen. Then I would try few times and it may work or not work at all. So I switched to GSM only (via the secret menu) and the phone would work perfectly, no issues calling out at my work desk or outside and getting all calls without any issues. The issue with this was that on a reboot the settings would go back to LTE/GSM so it was a constant change. On top not being able to use 4G Data speeds was making life harder.
Even when selecting 3G in network settings the phone would not switch to 3G only. I also tried different network provides like 3 UK, Vodafone but still the same issue.
I’ve now come to a conclusion that this is something software related (perhaps?) as the device is failing to switch to 3G when making/receiving calls. When I check the secret menu I see that DATA and VOICE connection is LTE. Now I know this device does not support VoLTE so I thought it would always first aim to connect to 3G signal?? NO?
As a result i’ve moved to Pixel 2 device because I tried everything from different roms to modems, going back to kitkat, CM12.1 and 13 as well as Oxygen OS but was still getting the same problem.
I’ve also come across posts (on google) that people with different oneplus device are suffering from this so not sure if something has been switched on/off on my phone when flashing different roms to have caused this issue or is this a hardware problem?
I’ve spent numerous hours trying different things suggested by many on google but haven’t got anywhere. I have given up trying to get to the bottom of this.
If anyone is out there who have had this issue and have found a solution please let me know, I still very much like the oneplus but with this issue it’s hard to use the device.
Thank you for reading…..

I can relate to you. have similar issue and also tried most of the things you have done. don't know what to do. if you have found something, then reply.
I think I have the same issue here in Italy too.
I tried all modems in the list and downgraded to kitkat but with no luck.
same issue reproduced on lineage os 16.0 India /Airtel

No calls incoming/outgoing over LTE network lineage os 16.0, when changed to 2G network calls works just fine
while LTE no issues with Data connectivity .
any luck for anyone.
Thanks
I don't have the phone anymore (in fact, the same issue made me get a new phone), but maybe try updating the modem?
