3G connectivity issues on Tmo. (not the holding in hand issue)

I woke up this morning and 3g was no longer working. The 3G icon on my notification bar still shows traffic (up/down arrows light up) but I can't connect to any websites, twitter, gv sms, nothing. When I connect to wifi or set my phone to 2g networks only everything works fine. Any suggestions?

Call tmobile ask if there's an outage in your area for 3g? If not i'm sure they'll transfer you to google tech support who can help you out more.
Sounds like this is a tmobile network issue or a potential bug with the latest release (did you upgrade?). If it happened after recently upgrading to the new froyo and especially if you didn't before or after upgrading.. do a factory reset/hard wipe (backup first just to be double safe) see if it goes away.

Same happened to me. Not the build cause my wife's tp2 also had no 3g. Then after 2 hours on the phone with tmobile and no help and all day later they both work now ..
It was definitely tmobile

Yeah there was a bunch of people complaining about data and connecting via 3g on the forums here. Figured it had to be one of the two.

Only using data/internet with 'H' or 'H+', not 3G

Something strange I've noticed with my Galaxy S II is that data / internet will only work if the 'H' (for HSDPA) is in the status bar, but not with '3G' there...the green arrow will appear next to the 3G when I try to connect to something but it will just time out unless it happens to switch to 'H'.
Anyone know why this would be? Is only the HSDPA network working with my phone, but regular 3G won't?

It is possible that the 3G cells in your area are fully loaded with users.

nvm
i didn't read it well

Same problem here, on 3.
Wondered if it was the phone or the network! If it's a problem with the phone it'll be fixable/covered by warranty though, right?

Same here, it sits on 3g then i try to load a page etc and it goes to h like it carnt use 3g , im on t mobile and they have full coverage where i am

I found an older thread that says it's a feature, keeping the phone in 3G mode to save battery until you do something that requires data which switches it over to H. I've kept a closer eye on my phone and that does seem to be what it's doing, usually taking a second or two to switch over each time I use data.
However, there have still been some times where it stays on 3G and is unable to load data.

Yeah i think your right and also it does not change sometimes and kinda hangs, be nice for it to switch over to H abit faster without battery drain.

I have the same issue with my phone to on t-mobile, not working on 3g then working on H.
It is a right pain to be honest.
No way of stopping this battery save? I would rather use more battery.

It's the network. I have no explanation but only Edge and HSDPA work whether on Samsung or Nokia.

Just tested, this does not occur for me, at least right here, right now. Comfortably loading pages on Google with just 3G signal (T-Mobile UK).
It's faster when I stand on my bed upstairs for HSDPA but 3G does work. Stock firmware from T-Mob, no modifications.

Hey mate,
I have the galaxy s i9000, with optus here in sydney. same problem, only switches to "H" when i make some sort of data request (load a page, open an app that uses internet), it takes a couple of seconds to switch from 3G to H. Sometimes, it keeps flicking back and forth between 3G and H like its having problems connecting to H
I complained to optus, they reckon i'm lying. Go figure.

Sorry.. just to add on, i've tried about 13 different modems on my i9000 and it happens with all of them.
The only fix I've come by? dial *#301279# and disable HSDPA altogether thats the only way my phone will actually load any data on 3G

I have the same thing, but as i understand H and H+ are the highest form of 3G, not a different thing. So I am wondering what mode we are in when 3G appears. UMTS?

Its all very annoying to be honest.
None of my other phones have this problem as they always stay on HSPDA

Same problem here to the extent that pages fail to load on 3g and come up with the error then when I refresh the page once its on H it loads straight away.

Actually this problem is making my phone more or less not usable.
I use the slingplayer alot, keeps skipping on the Galaxy S II as it seems to keep switching between H and 3G.
Put the sim card into my ZTE Blade (Orange San Francisco) and streams constantly with no problem with signal staying on H.

With all the threads relating to 3g and connectivity issues..we can deduce that SGS2's modem really sucks big time..and still no firmware update to correct this even though large number of people is facing some sort of problem with mobile internet which is a main function on todays smartphone.

Anyone know who to e-mail with examples at Samsung?
I guess they won't fix a problem if they don't realise there is one.
Some people will prefer longer battery when its on 3G then H, others will want the constant H.

I got mine a week after it released. The first two updates mine did the same thing, but instead of timing out, it would drop all signal and display the circle. After a reboot signal would come back. From KE7, it has not done it again.
AT&T in the U.S.

same problem, mode switches around when using data, 3 australia

Network Issues?

Hey guys, I am having serious network issues.
3G and 4G are not working at all, when im connected to wifi however the 3G icon turns on and is grey, once I turn wifi off it goes away.
Every now and then I get a blue 1X signal and it is connected.
It does not matter what ROM I am on it still does it.
I have my network set to GLOBAL. Ive tried all of the other ones and still no dice.
Thanks in advanced!

that could be your issue then. if you are verizon like your info shows, then you should be on LTE/CDMA/EvDo. set that, then try a reboot.

A full restore is the only fix.

I'm on that setting for the past 7 hours, restarted and still nothing :/
I also flashed stock 4.1.2 with the Batman utility and started fresh. I'm using Carbon now.
Would the "Network Operator" setting have something to do with this? When ever I go in there it just pulls up an error.

I get "error while searching for networks" - but no FC.
could have been a kernel issue for you then.

Same here...
I wonder if thats what is causing this somehow?

Here is a list of Verizon apns
APNs:
EHRPD - Verizon CBS
(VZWAPP)
EHRPD - Verizon FOTA
(VZWADMIN)
EHRPD - Verizon IMS
(VZWIMS)
EHRPD - Verizon Internet
(VZWINTERNET)
EHRPD - Verizon SUPL
(VZW800)
LTE - Verizon CBS

Tried removing my SIM card while my phone was powered off for about 30-60 seconds, it vibrated many times. Then I restarted my phone and it still won't connect to the mobile network.

No data but shows h+, toggle

Hi all,
Not sure if this is a problem as my network is upgrading to 4g, but recently I have on occasion seen h+ as my data signal but the phone will not connect at all. No Internet. Emails won't sync. Nothing. I have found that a restart seems to sort it out or flight mode toggle. This didn't always work though. This has only happened recently.
Anybody else have this problem, could it be the network upgrading? (Although I have only seen 4g on my phone once in a different location and the speed was not exactly great, I have seen over 20M on H+ and 4g was about 10)

Getting a 4G signal doesn't necessarily give you good speeds. 4G in our country sucks. I get 4G signal often but my speed still hover around 0.1kb/s up to 1.2mbps, but most of the time it's only < 600kb/s. Fastest I get is only 10mbps, that is around past midnight when everybody is already asleep. And yes, I also get H+ and 4G signals with 0kb/s speed.

The speed was more an observation than anything else, the issue is the fact that I have a network signal, I have H+ being displayed but no connection, as it sometimes clears with a toggle it would point to a phone problem surely?

I also experience that, even with my previous S3.

Guys I have the same problem. I just swapped from S3 to S5. I wouldn't like to change s3 but loosing connection was happening more and more often. Usually I was loosing data signal and only solution for that was rebooting the phone. Once I had to restart it 3 times in a row. Now I have S5 since almost two weeks and I noticed that sometimes I have H+ but I can't use internet at all. It's really annoying. Is it a problem with operators or phone? I am with EE now in UK but I had s3 in Orange.

I have saamung galaxy s5 g900f.my phone show h+ on stausbar but no internet in my room but when im on my hose roof internet is back.i have also s2 gti9100 same netwark fast internet on my room and my house roof. Help Help help

[Q] Galaxy S5 only connects to 4g

Hi, I'm very new to this site. Sorry if this has been asked before. I have an At&t S5, and it only connects to 4g and only in places where service is REALLY good. Anywhere else I will have bars but no 4g, 3g, etc. and is not connected to at&t. Ive made sure its set to gsm/lte. Any thoughts? ?

has your phone been rooted and have had a custom rom flashed? Sometimes the custom rom could have a different modem which causes these problems, you could flash a SM-G900A modem with odin and it might solve it, or just flash the stock rom which is a little easier but you lose your data

Hi, sorry for the late reply. I've been out of service area for awhile. The phone has been rooted before, but I've been having this problem since before the root.

hmm thats pretty strange, maybe it's only a 4g simcard or your phone isnt finding or there isnt any different type of networks in that area?

It just doesn't make sense that I would have bars but not have any connection to the network.

So youre connected but you cant access it? Send messages or use mobile data? That happened to me multiple times when I had a incompatible modem..

I will have bars but it doesn't say 3g/2g/H/H+/E. The only time I can text/call/etc. unless I have 4g, which is the only one it ever shows. And in places where my friends have 4g, mine shows nothing. Has to be like a big city.

No. It says not registered on network. I've tried all of the "Not Registered on Network" solutions all over the Internet and none of them work...for me anyway.
