HTC one with Three uk - Data connection issue

Hi Guys,
Been searching the forum about this but cant find anything so i have registered myself to open this thread.
So, i have recently bought the HTC one from Three (Moved from o2) on the unlimited one plan. The only problem is that I cant get the internet to work, the phone says i have 4 full bars of signal with 'H' connection but the pages will not load at all. When it does work, it will work for 10 mins and then would just stop working again till it decides to stop being moody again.
I have tried switching off the phone, re inserting the sim card but the problem was still there. Therefore, I have called up Three customer services and they said that ' THIS IS A KNOWN ISSUE AND THERE IS NOT A FIX' he also agreed that I can cancel my contract (employees in the store have different opinions all together). I now have a phone which cant get online (95% of the time) and a data plan that i cannot use!
So can someone who has this phone with three network UK please tell me whether you are facing this problem? If no one is facing this problem then i am happy to put it down to the handset and get it replaced if not i will leave altogether.
Please note, web browsing on wifi is fine and when i have this issue wifi is switched off.
Thanks,
Mareen
It's do to Three being too heavy congested... I get this sometimes on my LG fone. I have 2 different APN's that I use for Three & they both do this. Try, going into Airplane mode & then back on to reset the data connection. Sadly, this will happen due to more people using Three & they can't support the amount of bandwidth.
This is what happens with Unlimited data plans. The more people use unlimited data, the more likely you will have problems connecting at peak times... thus, meaning whats the point in Unlimited?!.
IMHO, network providers should be making sure they have reliable data connections rather than aiming for 100+mps data speeds!.

Thanks for your reply but this is not just peak time issue. I face this problem all the time and the customer services person also said it's a known issue and possibly there won't be any fix. He also stated the phone gets stuck in this mode due to all the apps installed by three but if that is the case then surely more people would have flagged this up.
I just don't know what to do. This one plan is so good and everyone at work are mostly on it but how can they connect and I cant from the same location same time if it is what you are insisting about congested network?

Wow a lot of hate for 3. I am using the one on the 3 network and do not have any problems whatsoever. I get consistent good speeds between 3 - 10 mbit/s without any of the issues described.
I am in London which is very congested. I am using an unlocked htc one and not a phone provided by 3 so it is possible that it is something to do with 3s Rom. But i think it is much more likely just a bad device and you should get it replaced.
It is definitely not a "known issue" with the phone or we would have heard a lot more about it on these forums.

Exactly! Hence this thread. Im also based in london and this issue happened in any locations i been too! Im torn between staying with them or getting it replaced.
If getting it replaced i will lose the 7 day cancellation period.

& tbf, mine doesn't just happen on peak times either. When I worked for O2 in Pay Monthly, I used to advise customers thats why they have a fair usage in place to prevent data connection issues. Unlimited Data on O2 used to be around 2GB/3GB & anyone who used to go over a lot used to get a text to let them know of cut off there data connection for that month. I left O2 a year ago after working for them for 2 years in Customer Services in Pay Monthly, so know a fair bit about signal & data & why there's generally a fair usage in place.
Three are VERY good at marketing themselves as All You Can Eat but as more people jump onto Three's network, the more you will have data issues. What Three have said is complete crap as my fone is sim free with no bloatware & its all due to there network & NOTHING to do with what fone you have.
I am on Three's Pay As You Go £15 300, 3000 Texts & All You Can Eat Data which Includes Tethering. Soon, Three will have to either cut back All You Can Eat or build more on there infestrure...
i would suggest its a problem with the '3' device. I am on a sim only plan with '3' and using a sim free device i purchased from phones4u, the phone works fine with only the occasional slow connection which i personally put down to congestion. I am in Wiltshire and generally get around 3 to 15mb download depending on time of day and amount of traffic on the network.
Never had a problem with my one on 3! Although in Milton Keynes today it went to Roaming!!!!!!!! Still worked (roaming was turned off) off to London next week so will see what happens with mine. Still mega impressed with the phone...
No issue with my 3 device in Essex and London, although do have issue 40 floors up but I expect that!
I'm on a SIM free device with Three. Never had a data problem yet and have excellent speeds.

Have you tried
1. Check the APN settings (try to delete and add again manually)
2. Set mobile network to 3G only (as opposed to the 2G/3G/LTE option)
Here I get barely 200Kbit/sec down and a megabit up, HSPA+ 21.6Mbit
In the next town I get 15+Mbit down and over 2 megabit up, again HSPA+ 21.6Mbit
Massive difference, and consistent with both places too. Three acknowledge the congestion issues and claim engineers are looking into it, but its been months.
Same speed on T-Mobile here so it's probably a MBNL site...no idea who to complain to tbh!
I get 10-20 mb dl speeds on Birmingham, never had any issues, don't really get the three hate. Been with them for 5 years.

Oh wow!
I'm getting the exact same problem but couldnt find anyone mentioning it so thought I must be doing something wrong!
I'm on EE (Orange) and I get cut outs quite regularly even though it shows full signal. Usually turning it on and off again or switching to airplane mode resolves it but it really is starting to pi$$ me off! :crying:

with ee its a totally different problem, there is a thread on it somewhere, its basically when you switch between 3g and 4g its cuts off,
have a look for the thread
I'm on Orange (although the phone usually shows EE) and I'm seeing this too.
If I leave my house, quite often as soon as the WiFi disconnects, I don't get a data connection. Again, I have the little "H" or "3G" displayed but I need to hit airplane mode on/off to wake it up.
Starting to wonder if it's a handset issue... I'll see if I can run some logcat next time I'm moving around. Doesn't do it all the time, if I leave work, then the wifi > H transition seems fine.
Thanks for the info guys. I used to be with three when they actually entered UK and their service was really good back then in my area. So i think this problem lies with the handset i think. Im going to pop into store and see what they say. Im just worried that if i do get a replacement it will have gap and power button problem reported by other users.
no issues at all, oldham
OK, decided to stay with three but they have promised me to replace the handset. So nice of them. I can only do this Monday as I dont have all of the paperwork with me.
I will keep you guys updated with how my new phone gets on.

Droid Turbo on T-Mobile. Need Help!

So I've had my droid turbo for a month now and I've been using it on T-Mobile and it has worked fine, no issues whatsoever, until yesterday when the service just stopped working. I have no signal at all. I took it to T-Mobile and they couldn't fix it and then Verizon who also couldn't fix it. I tried At&t and Verizon sim cards and they work, but for some reason T-Mobile sims don't work anymore, I woke up and it just had no signal. Also, whenever i put in my sim, i get the message "Restricted access changed voice service is blocked" Please help!!

I've been on T-Mobile with my Turbo for a little over a month now. Delete any APNs if you have any, reboot and test.
If no profit..
Turn wifi, Bluetooth, nfc, anything that connect to any kind of network off and run it dead, then charge it to full and boot back up then turn what you need back on, should have signal again.
If not..
Try another sim from T-Mobile, yours may be damaged if you frequently take the tray out over and over..
The Last possible solution would be to reset the phone entirely, so make backus f what you need beforehand. Then set it up from last backup saved to google if you have one and pop the sim in, let it sit 2-5 mins, reboot, then give it ~2 mins and you should have signal recovered.
If not, then may be an update gone awry or if you have it rooted and such, maybe something you used broke it.
Last problem would be a bad antenna, so try all the above before trying to replace the antenna.
Hope the best of luck for you :
Only Problems I've had on my Turbo was it turning wifi off randomly here and there, making me do a reboot every few days.
Dropped signal once, but that during initial use, so not much to blame on it there
I've been using a Turbo on tMob since 2 wks after release. That said I've run into the same thing a couple times over the past yr. Out of nowhere it just acts up & stops working. As suggested above I'd say about the smae things. So to no repeat it all my first suggestion is try getting a new Sim card from tMob. First time it happened to me it was my sim, other 2 times it was not, sim was good. Only option to fix it on my end was a factory reset of the device. On the resets tho I made sure to use tMob sim, but i also did not start the process until the msg pops up on the turbo saying its " Not a Verizon sim card" i'd clear that and then start the process of resetting it. So far so good as of late, been at least 3-4 months since the last time i was having troubles.

No Mobile Data

Hello everyone maybe you guys can help me out since my warranty with my Note 5 expired a couple months back.
My data isn't working on my Note 5 Duos, SM-N9208. I've tried both sim slots and also selected the appropriate sim for Data connectivity through sim manager. I only use one sim at any time. All functions on the phone work without any issues, wifi is strong but of course when I am out and about my data is useless.
I have a post paid plan with LTE 4G. My Phone will connect and show 4G/4G+/H+/H but receives and uploads absolutely nothing. I've done resets, I've formatted I even downloaded latest firmware for my country and telecom from Sammobile. Any ideas?
I know this is probably a stupid question but did you make sure that Mobile Data is turned on in settings?
yes it is and it registers the networks.
Update! After another firmware install through Odin I got Data to work but it only works with Auto Connect 4g/3g/2g. It registers to 4G+/4G and the device gets INSANELY hot with MASSIVE battery drain. Only Mobile Data is switched on using facebook. No other apps. If I try setting to 3G Only it won't even work, this is crazy.
I literally watched 87% to 54% in not even 10mins on FB and the device got super hot. Could this be a hardware issue? Looks like I need to bring my device to service center.
The firmwares I install are all for my country+telecom provider.
Device has been formatted several times as well to try to fix it.. never rooted etc.
it does sound like there is a hardware problem, I would take it to your providers service center ASAP and do not use it ( as experienced with the N7 fiasco, I think that you have a definite battery issue, how that relates to the no data I dont know maybe the overheating battery is affecting the software preventing your mobile data from working properly
Yep 100%! With data off and wifi using all normal apps and games it runs normally. I'll have to have it serviced.

[Q] Keep loosing Data Plan

For over a month I have been having trouble Keeping my data plan active (ie Phone,data and anything related to signal) I am on a Virgin 4G sim but my phone can only use 3G, Every time I activate my Mobil data everything works perfect for about 15-20min then it just stop dead... the signal bar is still showing 3 to 4 bars, I then try look at my Access Point Names then try Network Operators,And then Search Networks,It douse a 2 sec search and comes back out,Selecting Automatically douse the same, I cant phone out or receive incoming txt,phone ect.. nothing running in background. it dont matter if Im using Facebook,Explorer or any data plan program on my phone...
I then have to shut my phone off 2 times then everything come back,
Here is my Phone Details & screen image after loosing data plan.
Thank you for looking at this post...
Samsung Galaxy Note GT-N7000
As a last resort I got in touch with Verginmedia who told me that they had sent out a faulty batch of Sims.. they replace it the next day and the phone is now working perfect, Thanks VM

Have Wifi and 4g. When I call, sims disconect and phone goes crazy

Hey everyone, I'm currently having a problem that I thought might be a persist issue. I have Wifi and 4g, but every time I call with any of my 2 sims, they go offline. Phone has a few random restarts, sometimes it doesnt detect the sims or wifi disconects and I have to restart to get it back I found this post:
https://forum.xda-developers.com/showpost.php?p=82346409&postcount=76
by @tsongming and did the flashall.bat option using the "dipper_global_images_V11.0.3.0.QEAMIXM_20200118.00 00.00_10.0_global" image provided
Still get the same thing. I'm starting to wonder if there's a phisical issue with my phone. This started after changed sims and installed Pixel experience.... so I dont know which one is the chicken and which is the egg
Help!
