T-Mob connection problems

Hi I've been using HD2 for a month now. But from the first moment I bought it
I had issues with it.. I would have connection for sometime, but after a couple of hours I loose connection and I have reset the wireless connection
then it works.. Don't really know what's the problem,
I got a new Rom, but continue to have the same prob..
Could anyone help me.. I don't know whether its the phone or the T-Mob!!!
Thank you so much guys.. you are my only hope..

Your not the one its been happing to me a lot.....I believe most of problems are with Sense U.I HTC to me is a terrible manufacture now. Supposedly T-mobile is working on a software fix and it should be out and fix all these problems..Until then were going have to deal with it..

WIFI only works with firmware 1.23

Hello people, I have a question: Does anyone know why or how WIFI works for me only with version 1.23. And not with 1.3x or 2.0X?

I guess even HTC does not know why WiFi sometimes stops working.
My Legend got the 1.3x update OTA without any problems. When later the 2.0x update was pushed my WiFi stopped working. It showed no MAC adress in the adapter infos.
I wrote a support request to HTC but did not get an answer for about 2 weeks or so.
I found the thread here on xda developers in which is explained how to downgrade your legend. I downgraded my phone, WiFi worked again. I installed the 2.0x update OTA again and this time WiFi worked.
A few days later I received an answer from HTC. Only boilerplate stuff, not helpful at all. Later I received a mail asking me to rate their service - they received the worst marks in this rating.
When I was on holiday last week I got a phone call from HTC. Too bad I was abroad and had to pay high roaming costs - so I kept it short. They asked me about my WiFi problem. I told them that they were of no help but I solved the problem on my own. They wanted to know how and I told them.
I am sure they have no idea what causes WiFi to stop working after an update. Seems like some randomness.

[Q] Loosing data connection hard

Hi all, this is my first post or thread, i came here cause i heard from ppl this is best site for asking questions about cell phones, i started reading allot this forum and wow did i enter the other world i really like and wanna participate in.
Srry for little intro and lets get back to topic. So i got my first "normal" android and got trouble with it. I am using Samsung galaxy s5 g900F (european) factory unlocked and T-mobile as carrier with 4.4.2 kitkat. I have a big problem with a data connection that keeps going off every 30sec to 5 min if i use option to search and auttoconnect on LTE/WCDMA/GSM option. I read forum but no1 is mentioning this model as problematic 1 so now i post thread about.
Does any1 know what could be problem and how to solve it. Sometimes my data connection comes back and sometimes it doesnt and i have to switch type of network to get back again online. All other options that don't include LTE auttoconnect work just fine, i tried to get another SIM from carrier but same problem, i tried to get another Phone since i work in hardware firm and still same problem on another device, both were same models.
I still didn't put any ROMs but i really consider doing it maybe l8r on, it is stock version.
Pls be genttle since this is first time i post, maybe i did it on wrong place but i did read rules and everything and i think i did it on right place.
Ty in advance.

I did have a slightly similar problem years ago - when in roaming my phone could not connect to anything. What helped was a change of simcard for a new model - after that all was good.
Since you did try your SIM on a different phone (same 900F?) I would advise you to try: first on a completely different brand and phone model - if you can.
If this does not solve your problem do shake your service provider a bit - they could have supplied you with two faulty SIM cards in a row - that can happen. Otherwise - maybe there is a stupid limitation in your service plan which is causing this. There is no - to my knowledge - ready answer to the problem you have described.
Best of luck and if you do solve it come back and post - it will be very useful to lots of people for sure
Cheers!

Too many variables. You haven't observed enough of a pattern yet or tried enough things to narrow it down a bit. It could just as easily be carrier side issues as a bug in the firmware not negotiating a new connection if the LTE signal is lost.
A number of people were having data disconnect issues and that was addressed in the 4.4.3 /4.4.4 update. So that is one option to consider. And you could open a support ticket with your carrier. That is hit and miss as to results, but sometimes tickets actually resolve issues.
There are also a number of apps that may mitigate or possibly even solve your issue. Have a look at 4G LTE Switch and LTE Discovery.
.

Will try it today. Thanks for the help. Really appreciate it.

[Q] Note4 loosing data connection

Dear Friends,
has some who owned note 4 faced a continuous loosing data connection?
I have been facing this issue for the passed one week till now, I have tried to format the device but the problem is still there, I have not done anything to the device.
I called my ISP and they said that there is no problem with your sim card.
please advise if anyone of you had similar issue.
thanks

I've just experienced this today on my 1 day old N910C, I'm on 4G and suddenly earlier today my 4G mobile data indicator disappeared but it still showing the usual signal bars. Tested browsing, no mobile data it said. Tried putting it to Airplane mode then back to normal, didn't bring mobile data back. Rebooted it, then it's working again.

Not yet to see this problem but my friend's Note 4 had this problem. In the end he brought it to the service center and they replace the mainboard. Still wait and see if it fixes the problem.

it happened me before on other samsung devices too. generally an update fixes it but could be hardware problem too.

Hopefully its software related ive seen a slew of note 4s have this issue both variants included.. its annoying to say the least

Hi, I just got my phone, may i know whether you guys have resolved the issues?? i need to turn the flight mode on and off a few times to get the data connection back online

I sent back to Samsung services center, it seems that they said they reprogram the software. Will observe and see how it goes.

Mines all good now few updates and new provider all good ?

Hi guys, I've experienced the same issue, the mobile data connection suddenly drops (H+ icon doesn't disappear but the download arrow is off, meaning that there's no inbound traffic) and the only way to have the connection back is to to disable mobile data and than reactivate it. I've updated my phone, I even tried to install firmwares of other countries (different csc) and to change carrier but I haven't solved the problem (same situation on my friend's N4).

Hi
i had a problem with wifi. weak or no connection.
100% solution for my note:
go to settings=>location=>use GPS ONLY.
perhaps it solves also your problem...

Hello all! Just faced the same problem! Losing internet connection. Did anyone find a solution?

Note 4
Yes this is BS. If I go to a place with no data service, then travel back to a place with data service, I have to first disable then re-enable the "Mobile Data" toggle in the settings. It's such BS that this is happening. My note 3 NEVER has this problem. Starting to dislike Samsung's buggy releases.

Same issues..

----- got same problem here.. keep drop the signal.. until fedup already.. can someone solve this thing? Need answer.. T_T

Any news on topic? I'm facing with internet on mobile connection, even if bars are full and LTE sign is visible.
I've also noticed some lack of signal during usage, even if I'm constantly in city.

[Q] Mobile data problem

I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?

Mate i have exact same problem

I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks

Also experiencing this with Tmobile UK.

Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.

No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.

I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy

Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.

Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon

I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.

Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.

I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?

I think they're not available yet, at least on lollipop...

Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?

All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?

Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!
