3G Radio activity

Hello all,
I am having some issues with the 3G connection with my Dream that started a few weeks ago. There are times when it works just fine and I am able to use apps/maps/browser with no difficulty what-so-ever. Then out of no where it will stop working. I will have 3 or 4 bars, and it says I am connected at 3G, but only outgoing ('Up') arrow on the status bar lights up, while the incoming ('Down') arrow will not light up at all. Then finally after various wait times (2 to 10 minutes) the '3G' will disappear and light back up as if the radio is resetting and will work again for a few minutes before repeating the same process over again. If I enable the 2G only connection it works just fine. I do not see any pattern or correlation to this disconnect. I have tried wiping, reformatting the SD and re-flashing my phone with no help...
Any ideas? TIA
ROM: Cyan 4.0.4 Stable

Try airplane mode when this problem occurs.

You mean enable airplane mode and then disable it again to reset the connection? I just tried it...did not help. Still sending information out but not downloading anything in return...

it could be your phone
but also it could be 3g service in your area.. it could be unstable or weak..
i.e. i get terrible 3g service in my nearest mall,but 2g works fine.
but in my house my 3g service is almost perfect.

R u using a datasim or not??
Check with ur telecom operator. Sometimes u need to be using a data only sim to be using 3g on the g1. It happened to me. Otherwise there might be some apn settings wrong or missing.

Thanks for the reply guys. I thought it could be the 3G in my area but I have had my phone for well over 6 months now and it has worked great at my house. I know t-mobile is still working on their 3G roll-out so it could be that as well. I really hope it is not my phone but with my luck...who knows...
As far as the datasim, I am not sure. Like I said, I have had my phone for 6+ months and 3G used to work just fine. Is there any way I can tell by looking at my T-mobile SIM to see if it is a datasim or not?

My G1 is doing the same thing!
I am in Atlanta and i have been noticing the same exact problem. I am also noticing that i am suddenly getting mobile versions of websites that i usewd to always get the full web version. I am on cyan 4.1.7. Not sure if it is the rom or the service but nonetheless i am experiencing the exact same problem.

Weird stuff... I am in Los Angeles in case people are wondering.

if you want to take more precautions..
u can go to a corporate tmobile store and ask them to replace your sim card. its just something basic. some sim cards go bad. i had to replace mine twice.
if you go to a booth in the mall or whatever they may charge u $25. in a corporate store,its usually free.
or you can call tmobile and ask them to take off your data plan and then add it cak on again.. this again is a basic troubleshoot for data related problems..
and if it is your phone(i assume you bought ur phone from tmobile) you should have a 1 year warranty. tmobile might exchange or call htc... all you really have to do is pay shipping.

Awesome, thanks for your help. I have had to replace my SIM card a couple of times as well with previous phones but that was due to MMS problems. I didnt think of 3G/SIM problems but I hope that is it. Thanks again!!

I went to the T-Mobile store today and they said that a lot of people have come in with the same problem. So apparently it is a problem with the 3G network here in Southern California (at least the area I live in). I am grateful it is not my phone or the ROM but still kinda ticked off I gotta deal with it until the issue is resolved...

Ask them to reimburse you for the downtime

i too have been having the same problem as the original poster!
out of nowhere my 3g starts acting really funky and only the up arrow flases but it doesnt download anything. i hope this is a problem with the 3g network in los angeles otherwise idk what ima do.

whenever this happens.. it usually means that ur in an area that has weak 3g. i.e. i get weak 3g service in my nearest mall.
or ur areas 3g network is bugging up. but most likely its the first one ^

im having the exact same problem. been having it for a week or so. i thought maybe it was a bug in cyans roms but its not. i will lose 3g connection but i have a full connection and only the uplink arrow is on. this is really pissing me off. i live in los angeles and its been having 3g for a while now and i have never experoenced issues like this with 3g

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.

tmobile experiences?

Since apparently people can get this phone working on tmobile.. I was just wondering what your experiences were.. does it work easily/effortlessly? (I would likely use reseller lycamobile) and sometimes use Verizon reseller page plus

I am not sure what you mean by "easily/efortlessly". It takes a bit of work and patience to root and modify the phone. Once modified, the phone is usually back at the new phone state, so you have to reinstall all of your apps and some of the setting. If you install the wrong settings, it messes up the phone, so it is best to only use Titanium Backup to reinstall the downloaded apps and the update and restart the preinstalled software. I was not able to use Titanium to reinstall my text messages, but it did restore my WiFi passwords.
Once the sim card is installed and running, I get an occasional "toast" message about a UI error, but none of my apps seem to be shutting down when that happens so I just ignore it (I think I may have missed a step that fixes that). Some apps are no longer available because they were tied to Verizon Service (Smart Actions had trouble so I left it off).
I seldom get more than 2 bars of HSPA signal. However, that gets me about 7 MB/s download when I am stationary (about a good as my home network on a cable modem and about 1/2 the speed of Verzon LTE) but the power consumption is much lower. I can expect my extended battery to only use 30% by the end of work vs. 40-45% with LTE active (both on WiFi). Off of WiFi I get just over 50% longer life than I did on LTE.
I have no issues hearing or being heard on a call. I get signal almost everywhere I did with Verizon in the Metro Indianapolis area, but I seldom have a good Data signal on I-65 between Indianapolis and Gary (voice works).
I hope that covers the questions you had in mind!

I take it after you do all this.. you can't just flip the phone back onto verizion.. after running say "tmobile" (you have to re-rom the phone or something right?)
I also assume you can switch to AT&T though without much trouble?
Does the phone have a external antenna port.. I would assume "no" ?

It is not so much "re-rom" as you have to wipe the data cache clean, which means all or your apps and messages are erased.
I have not tried switching between t-mobile and AT&T (I don't have an active AT&T SIM card) but I don't think that will be a problem. The boot looping is caused when you change the settings in the build.prop file and you would not need to do that when switching between GSM carriers.
I can't remember if the Bionic has an external antenna port (my wife has one, and my daughter the other - I am on an old iPhone 3GS until I replace somebody's handset).

There is an antenna connector or the phone. Pull the back off and it is visible between the battery and the lower microphone.

Why am I randomly losing mobile data connection / failed text messages?

Background:
-I've had my galaxy s6 since May 2015. I had no problems with mobile data at all until about 4-5 weeks ago when we upgraded to the At&T family unlimited data plan.
Problem:
-My data connection will come and go. I'll completely lose connection for lengths of time throughout the day ranging from 2 minutes to a 3-4 hours. I've been keeping a log of it this morning and it's been ranging between 5-20 minutes intervals of no connection/connection. Sometimes it will still show bars, other times it will have the circle with a slash through it icon. This happens everywhere, location doesn't seem to matter, at all times of day. It's not a slow connection. It's either fast or completely non-existent.
-I also lose the ability to send and receive texts when this happens. I'll get a "send failed" type message.
-Other people on my data plan, with different phones, will have a perfect connection standing right next to me while mine is down.
-When I lose connection, the phone also gets extremely hot while trying to regain a signal. So hot that it will literally burn me.
What I've done so far:
-Read many articles/forums throughout the internet trying to find a solution / troubleshooting.
-Contacted at&t's live chat and gone through extensive network troubleshooting with them (twice).
-Gotten the SIM card replaced.
-Factory reset / Data wipe.
-Left the phone at a local repair shop where they looked at it and changed some settings and told me it was fixed. (It wasn't)
Question:
-Is anyone knowledgeable enough about the hardware components of the S6 that could tell me if this sounds like a part may need to be replaced in the phone? Could the antenna or sim card reader have been damaged or gone bad? Any other ideas?
I've also read some things saying it could be a software problem, but wouldn't something like that be a big issue with the entire At&T galaxy s6 community?
Thank you.

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.
