Whats up with Tmo network ?

Both of my phones cycle from 3G to EDGE to weak signal.....this is MA in full 3G area

1- Different Modem or Kernel
2- Change ROMS
3- Your phone sucks bawls.
either of those.

Are both Phones running the same rom, same modems etc?
If yes, then its probably a network issue from TMO themselves, and you should call them to ask them if anything is going on, and if nothing is, they'll either:
1) give you instructions on how to get better signal
2) give you a little modem thing for better signal that you connect on your PC.
i have the little modem thing, its like a little cell tower i was part of the BETA program.

interesting seeing this thread because bout an hour ago I lost my data connection and camt get it back. not this first time this has happened. l

Then for sure its a TMO problem, not yours.
Call them up, ask them whats going on, and get a answer.
It's perfect here in Texas for me.

I had the same problem too, but i went to mobile network via settings and switch network mode to gsm instead of gsm/wdmca or something like that. worked for me.

looks like they fixed it now.....now get all bars

At around 9-10 est I had the same problem. I had full bars but the data was slowed. Its better now though. Maybe some work being done?

Here the past few days, my data, which is usually around or about 2-3mb down and .6mb up has been at 5.8-6mb down and 1.5-3mb up

I have to set my network settings to wdcma only to avoid constantly switching to edge. I only switch to auto mode when im traveling.

Here in Puerto Rico it has been hell on all of my family phones.Starting with call not wanting to go out,many times i get a message saying all circuits are busy.And then something incredibly weird,i call some one and all you hear is like a bunch of sound like they are from an old PC dial up modem but not quite in that patter and fast and you hear like some one is breathing at the same time.
Like some estrange sounds use in movies to simulate Alien voices or some sh** like that,i tough it was my phone,i am running Toxic Fire,but my wise have also heard it and his Vibrant isn't rooted and doesn't have any custom rom,and also my friend which is on AT&T hear it when i call it a few days ago.
And yes Data rates had been to low at times.

Im in florida and had some bad reception issues from like 5pmest Friday till 12pmest Saturday. Don't know if its related or not.

Its spotty. 3g is fast where I live in Framingham, but I noticed in other areas in Framingham 3g is as slow as EDGE, and some places in Newton and Brookline only have EDGE.....I mean its 4G era and we should have almost 100% 3G coverage by now. I dont see the point moving on to 4G, I would be MUCH more happy with full 3G in MA

It happened to me a few times this week (DC Area) and I thought there was something wrong with my phone. After rebooting my phone for a few times, and playing with network mode, and lastly checking my wife's BB, I realized it must have been T-mobile network.

I've had this problem for a while and finally after numerous calls to T-Mo i figured it out.
I live inbetween a crappy Edge tower apparently in the boonie area about a mile away, and also a 3g tower about the same distance in the other direction in civilization.
It constantly switches on me when i'm at home to whatever it feels like, usually edge... I think just to get under my skin on purpose.
When i finally realized that I went to settings - wireless and network - Mobile networks - Network mode - then put it on WCDMA only. Boom 3g all day.
If you happen to go into an area and you lose service, do the same thing, but instead of selecting WCDMA only, put it on auto and you will be able to use edge service as well again.

HSDPA Problem

Hi, not a big problem as I am normally on wifi but I've noticed that my GSII is constantly dropping of HSDPA every few seconds and if I do a speed test it only gets around 300kbps.
Now I have an LG Optimus on the same network, same room and that stays on HSDPA and gets around 1800kbps on downloads.
Any idea what would cause this?

Don't have another phone here right now to test against but just did a couple of tests with speedtest.net app
Download/Upload
2500kbps/1967kbps
1422kbps/2967kbps
6192kbps/2883kbps
2896kbps/2608kbps
Seems to work just fine here at least. Granted this is at a place with good HSDPA coverage.

Sorry to tell you that but it seems like a bug in the phone, i do have the same issue, i surfed the couple of forums and the problem is spreading, hoping it's not a hardware issue.

goes down to 2mbps when it's lower signal.

Yes I think it's a phone issue as my HTC Desire and LG Optimus are both working fine.
Hmmm. I hope this can be sorted with a software update.

mine too, infact wont go over 1900 had like 3500 on my iphone 4

Just updated to the newest firmware using Kies and it made no difference to the problem with HSDPA :-/

I think it's a network restriction. People in another thread were having similar problems with buying the handset and the contract separately meaning the data plan they were on was only at 300kbps.
If you've got another handset that gets a higher speed, switch the sim cards and see if that changes anything.

My phone will only download around 360kbps but will upload at 1mb, so puzzled as to why it would be a network restriction (hoping it is as I'm not happy and still within my 14 day cooling period) ringing o2 later...

No, it's not a network restriction. Not on Three anyway. I've just taken the PAYG SIM out of my LG which is getting around 1800kbps and put it in the Galaxy SII and it now only gets 64kbps!!! It's constantly flickering between 3G and HSDPA. It's definitely a phone issue.

i had posted in the other thread about how it switches down to 3G when it's not being used and instantly switch over to H+ when in use. There were no performance issues
Also on AT&T network, when it's first started/activated it took a little bit of time before network performance improved both on day one and when i switched over to an unlimited data plan

Oh I forgot to mention. I reported this issue to Samsung yesterday but don't hold your breath!
The man I spoke to didn't seem to understand what I was saying and when I advised him that there were many similar problems and issues being faced by people on this forum, he simply stated that he had never heard of the site. I gave him the web address but doubt they will ever look in to it.
If your facing this issue, then I would ring them and report it. That's the only way they are going to find out about the issue.

Normal behaviour for it to sit on 3G, only switches to H+ once it's in full flow.
This usually impacts speedtests and such.
Best way to test is to download a file off a fast server.
Same thing use to happen with my Desire.

I have numerous 3G devices here and none of them cuts of HSDPA so erratically. If I start to stream AudioGalaxy on my LG Android, the HSDPA stays on as does my Huawei MiFi. The Galaxy S II is dropping connection every few seconds.
It doesn't make sense for two Android phones in the same room with the same network to get completely different speeds. Maybe a small difference but to get one having 1800kbps and the other 64kbps shows there is a problem.
I've just updated the phone to KE2 and it's made no difference. Will have to wait to see what Samsung say.

How strong is the signal in dB or just bars whe nit switches around between 3G and H/H+?
That last sentence - did you contact Samsung with the problem and are waiting for their reply? thanks

It's around the -100 dBm mark with 2 to 3 bars. Yes I contacted Samsung yesterday and am now waiting for a reply.

SLOW 3/4G DATA SPEEDS bell i9100m

just picked up my new phone, however 3/4g data speeds are crap. speed tests come out at less then impressive (when i can do them) but real world performance is far bellow what the speed test says. i am pulling about 1Mb/s down and about 1Mb/s up (usually less but im rounding), now the fun part, if i try to pull up a website, it is slow as hell or times out. google market also times out 70% of the time. downloading a 1mb app can take upwards of 7 minutes as it pauses while doing this, facebook app usually times out or works for a few minutes and then stops receiving data. all this said, my battery died at noon today because my phone was constantly trying to sync with gmail, FB, google+, etc. if i watch the data activity icon it looks as if my phone repeatedly sends off requests but does not receive data back. i have seen that some at&t users with an unlocked i9100 are also having the same issues, but they seem to mainly be a apn issue. others are using root explorer to change some config files. am i alone? is my phone defective? or is this just my new galaxy s2 ruined by bell?

If I am correct, I think you should be able to experiment with the different modems avaliable for the SII.
For me the newest euro one has the fastest speeds, but that depends on the network and country you are in!
Best,

Weird.
I did not have any of those issues so I think you have a dud.
Take it back before you start trying other fixes etc as that's what the return period is for.
I've used it since yesterday (Thur/21) and didn't notice any issues/problems with WiFi, or HSPA+ speeds.
Hrm... mind you I didn't actually use it on Bell, could be their network.
As soon as I got the sucker I rooted / unlocked so I could pop my Rogers SIM in there and it's fine on Rogers.
Actually there is one thing you could check before you return.
Do a *#0011* and make sure your WCDMA says 850 Band 5, if it says 1900 it will be as slow as *[email protected](.

How is it that you change it to 850?

My baseband version changed to XXKG2 when it was originally UMKG2. This is probably why I'm showing as 1900 band when I do *#0011#*.
I'll have to wait for someone to post the UMKG2 modem file.

Could be Bells network. I thought maybe the custom ROM I am currently using was to blame but I am experiencing everything you are with my sgs1 and have been for about a week now. I'm in Calgary.
Edit : Also I get the best speeds on 1900, 850 is only useful out in the mountains here.

Dude you do realise that this is quadband GSM and quadband hspda phone. This means if you are on 1900 currently blame your provider or maybe you screwed band selection which is easily corrected. I usually turn off euro GSM and 3g frequencies and leave only our 850 and 1900 bands to save battery so it does not keep searching for 2100 for example.

Bell throttles their upload speeds, haven't touched their download speeds as far as I know.
Speedtest gives me 800kb/s but downloading I get 1.2Mb/s.

Same boat. On Rogers network and only getting ~1.5mbps.

ok, i am running on the 850 band 5. i did notice a slowdown on my sgs previously but not the timeouts/drop data connections/etc. i just finished a factory reset and lost all mobile net access for about 2 hours but have it back now (kinda). popped my sim out and back into my sgs and am having similar problems with the sgs but not as severe. i guess i can chalk it down to network issues that started up within 5 hours after buying the new phone. talked to the place of purchase and they are saying the network is loaded do to "rib fest" which in all reality only pulls maybe 1k to 2k of people that are already up here cottaging so i have trouble with there theory that the local towers are loaded as really its only one tower thats loaded more than normal. love the phone, wifi speeds and page rendering is retarded fast. i was watching a 720p video streaming from vimeo through the phone and scrolling around the page, it stayed smooth as butter. i just want my mobile internet to work. past that, when i have been able to do a speed test i have got no more than 2Mb/s, a far cry from what the technology can do. I hate you bell!

I have by Bell Galaxy S 2 running with telus, I am getting between 2-4 mbps download, and 1-3 mbps on upload. I an only getting up to maybe 1mbps on wifi, download or upload. I am using a 2.3.4 custom Darky Rom.

I'm getting 3 to 7mbps download on 4g and 1.5 to 4mps upload. Purchased from bell. On bell network.
On my home wifi 16mbps to 19mbps down, 1mbps up right next to the router.
I am using KF3 modem(radio) and it has improved the speeds and reception.. slightly (5 to 10%) but i do find the wifi signal doesn't crap out anymore which as my problem.
Try KF3 modem, put the file on your phone and flash with CWM http://www.mediafire.com/?fnkld9swo6u99
keep in mind there is no official ROM for bell yet so if u flash custom roms you wont have warranty until stock firmware is released for it.
maybe u gusy are in low 4g coverage ares? im around the don mills and lawrence area in toronto.
first one is 4g, second is wifi

Its probably most likely bell. Its nothing but corporate ripoffs. If this was the U.K they would be out of business. I dont see anywhere near 2mbit in newfoundland either.
*#0011# showd 0 HSPA+ connections so im guessing either bell doesnt have hspa+ here or bell has severely crippled the provisioning in favor of their internet sticks. But even then when a person pays nearly 60.00 a month for an up to 42mbit connection, it states that average is only something like 5 to 8mbit.
I share the same slowness and timeouts as you.

It seems they have bad coverage there. Why don't you get people in your area to sign a petition for Bell to install some antennas in the area and send it to Bell... worth a shot.

I am on Sasktel and the data on the Galaxy S II is quite poor. I have been getting aroud 2.5 Mbps Up and 2.5 Mbps Down max, this is including build.prop edits. I have tried KH3, KH1, KG3 and KG2 with KG3 yielding the best results. These numbers are about the same as my Nexus S but the Nexus S yielded much more consistant results.

2.7Mbps down and 1.5 up with KG6 on Telus

8 Mbps down & 1 Mbps up - On Virgin Mobile, HSPA+
Try flashing the KH3 modem using Odin, it's said to work extremely well on the Bell/Virgin network.

Just put the KE7 modem on my phone, pulled the best numbers I've got yet and I have tried MANY modems. 6012kbps up and 2633 down. Will continue to test and report back if there is a change. This is on Sasktel with a KH3 based rom.

Decent speeds for me in Guelph on Rogers.
*edit* After seeing some of the above posts maybe it's not so decent after all. Maybe I'll try some other firmwares for kicks.

Aaaargh fecking signal!!

Why does my phone show full signal yet all apps that use mobile data either run shockingly slow or not at all!! My steam app is constantly reconnecting yet signal is constant! In BBS it's showing i have good signal for a matter of minutes and is mostly showing poor or unknown signal nearly the whole time the phone is on!

Could be you only have full bars of 2G data speed. You are either being throttled for excessive use from your carrier or your carrier only has 2G speeds where you live. Where I work the entire county only has 2G Edge speeds from AT&T even though their coverage map shows 3G for the area. Check your data type and speeds with an app like Network Signal info.
https://play.google.com/store/apps/details?id=de.android.telnet&hl=en

Happens to me a lot as well. I show full 4g and yet everything times out and wont load because data is so slow. I'm also in a good coverage area where i get 12-14 Mbps speed with other phones and when this one is acting normal.

The towers you are connecting to are probably overloaded. Thin of them as a wireless access point at your house with 1 internet line. If too many connect to and use that line, the connection gets slower. Would be nice if cell providers posted tower stats in your area. Would save a lot of angry calls

Glad im not the only one suffering.. I didnt really have the problem on stock so much.. just since unlocking and flashing new roms.
To the person who mentioned carrier throttling, its certainly not that as one minute i'll get full speed and the next (youtube for example) will just stop and start saying no signal retry and then if i turn the phone off and back on again it will work. How can a carrier throttle you when you only have a 2Gb usage limit and then they charge you afterwards that makes no sense.
Also its not a 2G problem as Signal checker shows 3G and also now EE all around my area. Besides my wife's S3 on the same network is getting full speeds where im not or anything even though im apparently at full strength H
I hope this gets sorted soon as its also affecting calls.. I'll have what looks like full signal while playing a game then suddenly a text to say someone tried ringing me like 3 minutes before!!

probably switching from HSDPA to HSPA+.
did you notice a H on top of your signal bar, that switches to H+ when the lag is over?

I have had this problem for a long time, since I got my Galaxy Nexus and now again on my Nexus 4, and finally got so fed up that I have been testing it all day and getting screenshots ready to make my own post about this so I am pretty relieved to see this post!
I live in Philadelphia and use T-Mobile. I have had T-Mobile here for years and never had this problem before. When they upgraded to 3G I had amazing speed boosts and when they did HSPA+ it got even better but that was on a G1/G2. On my Nexus phones the internet is damn near unusable in center city but what is so odd about it is that in my Google searches about the problem I can only seem to find posts raving about T-Mobile in the city and how Philly keeps getting improvements including the new improved 1900Mhz HSPA+42 but I have never even seen my Nexus 4 on the +42 network the best it goes to is +15 and even that makes no difference because the internet is so slow and unrelaible that unless I am on Wifi, my phone just sits in my pocket useless.
I'm really at my wits end about this and no one, Google or T-Mobile seems to take responsibility or have any advice on how to fix it except the pointless factory reset.
I've seen a brief mention on XDA about a fast.tmobile.com APN and I changed to that and I'd like to imagine that it showed some type of improvements but certainly not with data speeds/latency/integrity of connection. If anything, it may have improved signal 'strength' (used lightly because regardless of what my strength is listed as the connection sucks.
To be clear, I am connected to HSPA and HSPA+ when the connection is being used, like it should, but these are the best speeds I managed to get throughout the day today as I moved around campus trying different spots.
Please, someone have advice!!

I am using the stock kernel, stock radio although not the stock ROM. I am pretty sure I had this problem before I rooted (I say pretty sure to be conservative with my answer since I am not 100% sure but I am definitely 90%)
Is anyone confident about their knowledge regarding APN settings? I have seen like 15 different configurations for T-Mobile's APN and have no idea which one to try and would prefer not to just go through them one by one -- I've got things to do!

Again.. I'm pretty sure i didn't have this problem while on stock but i could be wrong. My GNex was exactly the same. And I'm on orange UK so completely different network to the T-Mobile USA so surely can't be random that we're both having the same problems

Settings for LTE revert to WCDMA every time I lose reception. Also dialer crashes/ force closes if I have an incoming call and sends all calls to voicemail. I can dial out but at the end of my calls when I go to hang up I see the popup that phone process crashed.
My carrier is Bell Canada and the phone worked fine for about 10 days before this started happening.
Any tips or advice to help me out is appreciated. Thanks.

[Q] Data Issue VS980 - Verizon

Basically I have tried stock reset using LG Flashing tool i have rooted and tried numerous roms, but the problem is i boot my phone it has 4gLTE full then 5 minutes in it switches to 3g network. I have called verizon and tried everything they told me. Also i have even tried and made sure it was on the correct network which is Global or CDMA/LTE
I wanted to know if any deveopler can help me here to figure out the issue with why its not staying connected to 4g?

One of two things. There is issues with the towers around u which would be a Verizon problem. Or its hardware related

its sounding like its hardware related before i upgraded to the LG g2 i had .. i even dialed *228 to locate towers my area is all red on 4glte and im right next to the tower

can someone please help me with this issue it is irritating me very much because i pay for 4glte not 3g ****

so no update on this no one having the same issues as me loosing 4glte and connecting to 3g

Have you tried a new SIM card? On some LTE devices dialing *228 can actually screw up the SIM data. You should try a new card.

Have you tried any of the different radios / modems? Might be worth a shot.

Just got my G2 a couple days ago and I can confirm that I am having the same issue. I haven't found any fixes yet. It does seem that as long as I am actively using the data network, I keep 4g. Once I quit using data or go to wi-fi though, I switch back to 3g after a short period. Quick toggle of airplane mode and almost instantly connects back to 4g again, with the same results of dropping shortly thereafter.

I'm in a spotty area, 4G sticks on one bar and rarely reverts to 3G. Signal loss very rarely. Always comes back auto. Faulty modem sw, SIM, hardware, or towers.

I called lg about the issue they say it was Verizon's fault and there radios .. So they sent me the international version works perfect now I would recommend anyone here to drop Verizon they are **** and highly overpriced
