Roaming Issue - Galaxy S III Q&A, Help & Troubleshooting

I am on 3 Ireland and i visit the UK quite often and the phone automatically defaults to 3 UK, but ive noticed when i return to Ireland only in certain places for example in work the R (for roaming) letter shows beside the signal bar in the statusbar and it wont connect to the Internet, when i go to settings > Mobile networks >Network Operators > select automatically it doesn't always reset it to what it should be whereas sometimes it does, this only appears to happen in certain places too and it's a bit annoying to be honest, pointless talking to 3 Customer service too they keep saying "you must be in a bad signal area" right since when was Dublin City Centre a bad signal area then.
Does anyone know why the phone is doing this, as i said it only appears to happen in a certain area, my SGSII never gave me this problem at all.

Bump..
anyone have any idea as to why phone behaves like this?

Mine shows the R when I don't have very strong 3 signal so it hands off to whichever network 3 have their network sharing agreement with.
Do you have the data while roaming box checked in mobile network settings?

No always have that unchecked as im not roaming and only use WiFi or my UK SIM card when im outside Ireland.
It's bizzare because it only happens in a certain place in the Dublin 3 area,i haven't seen it happen anywhere else, it's a bit annoying actually as i cant access the Internet then off of a sudden the R goes away and im back to normal.

Well check that box because even though you are in Ireland it is still considered roaming because you aren't using 3's network when the R is there.
I'm given two choices on my galaxy nexus, national roaming and international roaming, but on my S3 its all lumped into one checkbox.
You'll need to have it checked to get Internet connectivity when the R comes up.

Vodafones network is bigger so they don't need to share.
3 share network towers with someone (02 I think) to help boost their national coverage percentage.
You can't get 3g data while the R is there, only 2g.
But Vodafone don't have unlimited data and where I live 3 hspa+ is faster so there's the trade off.

that is strange alright but cheers for the heads up i will check this box,i assume i need to uncheck it when im outside Ireland too.

Roaming not working at all
I got to both UK and Germany and I got a strange behavior: I was connected to a network with full bars but notification bar was showing "emergency call only". No way to both call, text or receive.
It worked intermittently for the 10% of time only.
No luck switching to 2G only, selecting an operator manually or rebooting the device.
I'm on AFL6 fw, but it did not work on previous two releases as well.
My home carrier is 3 Italy.
When I got back home I had exactly the same issue when moving out from flight mode, a reboot solved it tough.

Sweden 3 and gets connectivity lost due to roaming every time I fire up wifi

Fixing Signal Issues (3G/H Switching)

Hi
Does anyone know how to fix this issue? I am in a good area for signal and with previous phones am consistently on H. With my S2 it frequently switches between 3G and H even if it stays in the same spot. It will do it every few minutes.
This is causing havok when I try and tether and my Transformer and laptop keep getting signal interruptions.
Does anyone have a fix? I have Fast Dormancy disabled and I'm aware there may be some other engineer menus that have signal settings in that might work?
Thanks
Paul

Interesting.. And I thought it was just my network vodafone
Mine also switches between G/H/H+ all within 5 secs... yeah 5 seconds and it is kinda annoying.
Are you on GIFFGAFF as stated on you profile? or other network? cause I thought if might have do to something with vodafone..
Otherwise may be its something to do with the hardware settings, I too would like to know the answer
I've kept mine to use WCMA all the times...

Yes, I'm on giffgaff.
Glad its not just me. Maybe the antenna is a little too sensitive.
Anyone know the secret code to get to the GSM/UTMS bits?

Now, for me wouldn't 3G and H/H+ both be considered as WCDMA under Mobile Network Settings? G and E would be GSM right?
If that is the case, staying on WCDMA wouldn't fix the problem.

Your phone shouldn't lock onto a H/H+ signal unless it has started to download data. That's how the protocol works.
If your phone is sitting idle it should be on 3G.
You should only get H/H+ when your phone is actively downloading.

OK. So how can I stop it flicking between the H and 3G. For instance when I am trying to stream it will get interrupted, or if I'm wirelessly tethered?

i'm from tunisia and have the same pronlem here.
Please developers help us to get rid of this 3g/h issue.
Guys,
I got the same problem here i n Brazil using a VIVO carrier.
I set in CONFIG -> WIRELESS AND NETWORK -> MOBILE NETWORKS -> NETWORK MODE -> WCDMA ONLY
I don`t know why it worked but now its working fine.
Could you test?

No problems to report in Amsterdam.
I'm biking through the whole city to get to work, no disconnects using TuneIn or Google Music. Provider is Vodafone, HSDPA+ all along the way.
Its Android issue
Think when iPhone, Windows phones have not had this issue, wat else other than Android. I have tried 3 different handsets. 3 different network - 3, O2 and Vodaphone. All has same problem. Android is the only thing common. I have been scouring the internet and posted everwhere possible since Dec 2010 from when I became Android user. There is no solution. Everone seems busy making their own Android versions and apps. Result there is no basic data and voice stability on Android. Have been relying on my decade old treo to receive n make important calls. Wonder where this is going. My heart n soul seems to sway to the iPhone lately. Atleast wat they give works well.
Its Android issue
BTW those config settings are useless too. I have even used the code to get into hidden menu and change config but no use. It's the same issue. From H to 3g and from G to E I gsm.
Sorry for the question, but whats the problem with switching? I have the same thing but is not a problem for me.
Sent from my GT-I9100 using XDA App
Nobody should get worried about that switching, THIS IS NORMAL!
H/H+ is an high speed 3G protocol.
Basically:
1. 3G means DL 384 Kbps tops. The modem is under 3G signal most of the time. Whenever something on your phone starts checking/d-loading it communicates at THE BEGINNING under 3G protocol. Also, long ping time> 210 ms.
2. HSDPA max 14 Mbps/HSDPA+ can go as high as 42 Mbps ( topped only by cell tower). If there's need for large packet data or shorter ping time, IT AUTOMATICALLY SWITCHES TO H/H+(IF AVAIL). Hsdpa consumes more power and it's a communication protocol. When connected under H/H+ error correction bits are transmitted along data stream. It's like switching your home wifi on b/g/n. ...or like the automatic gearbox going to overdrive.
If you see a lot of this switching it means there's a lot of downloading/uploading going on.
I have it switching too between 3g and h on o2 and its making the internet so unstable you cannot do anything at all. This is certain not normal as the switch happens every second and continues to do so until phone is off
Mine is also switching to 3G once connection is idle for about 3 seconds. So far no problem and it uses less power than my SGS1 for browsing since my SGS1 doesn't switch to 3G when idle.
Mine is no problem between this signal switching, check your area or check your country maybe too much communication devices there so that's why it is distorted. Just use the common carrier with plenty of cell sites for a good signal of your phone.
What do i need to dial to fix it to 3g only from 2g?

ATT customer here. Is there a way to set up Roaming on this phone?

Just like the title says. Some areas where i drive i dont have any signal at all, and i was wondering if there is a way to set this phone up to roam on T-mobile or another gsm network if i am outside the coverage area. I know the phone is capable of using t-mobiles edge network according to specs.
It doesnt work if you check the data roaming under mobile network settings?

Display Carrier Name in Status Bar

Is there a way to display the carrier name beside the signal bars, my Note offten times goes in to emergency calls only but still displays signal and I will not be able to tell until I locked it and take a look at the lock screen to see if I am on a network or not.... (for anyone wondering why I want it displayed)
So question.. is there a way to display the carrier name in the status bar on the home screen?
If it is often going to emergency calls I'd suggest you get it replaced. If you're on att we still have a few days left just bring it back where you got it tell them what's up and they will swap it out. Just for ****s get a new sim card I'm on my third card for this phone cause of little issues we thought might be solved with a similar swap. Should be free, was for me
I know this isn't what you are asking for but what you are seeing should not happen and most likely is a phone defect.

The thing is. .. Its related to LTE and i live in a fringe area if i set the phone to hspa it stops doing it so i was wondering if it was possible so i could see how offten i actually lose my LTE connection.

It might is possible if rooted or on custom Rom. But as far as i know it is not an option in the stock settings so can't be done unrooted.

My bedroom is a fringe area depending on where I move the phone it gets hspa (wow my note auto corrected that to hepatitis haha) and I don't see the emergency call issue you are seeing, but do get the network time problem but only in my room. That's just really strange behavior.
I'm just saying if it could be a phone issue replace it now while you can still get a new in box replacement.
Maybe there is an app to count the handoffs or something. Is the difference in 4g icon not satisfactory?

Plus are you not seeing the circled icons? I'm just rooted with the OC kernel and see this.
Sent from my SAMSUNG-SGH-I717 using xda premium
Yeah my lock screen shows me the carrier name not in the status bar like yours but rather right below where yours is. .. The funny thing is i work for the carrier and i know my area is very poor for LTE and handoff is not occuring properly which is more related to our simcard and a PLMN issue.
This wont be fixed for a.while so i juat have to get creative. ... I dont mind rooting it i just want to make sure i can do it before i root it

Need H+ to download?

Hi guys. I noticed today that on my rooted T-Mobile Phone, I cannot download anything unless I have a H+ connection. G/3G/H doesn't let me download or upload anything. Can anyone help with this? I'm using the latest Jelly Bean leak (NOT the official one)

Hi im also on T-mobile and can download when on anything from 3G and above.
Try changing your Modem until you find the right one for you.
Also does your network name show as just "T-Mobile" or "T-Mobile Orange"

Both, really. I think mine automatically changes. And as for modems this seems to be the fasted for me as of yet.
Sent from my GT-I9300 using Tapatalk 2
Well the reason why it keep swapping between the 2 is because of poor signal.
But if you goto SETTINGS---MOBILE NETWORKS---NETWORK OPERATORS then wait for it to search then a list of networks will appear.
Select T-MOBILE and it will register you on that network and should find things much quicker.
Be warned though that once your in a lower signal area you will drop to sowing both and will need to do the process again.
And may be worth doing this process everytime you reboot the phone even if its showing as just the one.
I personally have to do this and find that when my network is showing as both then i get browsing speeds only. But when i register it on just T-Mobile then everything like download and streaming are perfectly fast
Damn. Do you think when tmo and orange become ee that it will be a permanent solution?
Sent from my GT-I9300 using Tapatalk 2
Yeah because Orange and Tmob will be gone and only EE in its place so yes i can see signal stregth becoming stronger and stable. Rather than swapping between the two all the time.

Signal loss on EE UK S3s?

I'm based in NE England and work in an office with 5 other S3 users all of which are on EE. 2 bought Sim free phones and use an originally Orange Sim, one has a branded Orange phone and one has a branded TMobile one. The other person has a Tmobile 4G phone. The only one that isn't stock is one of the Sim free phones (mine)
All but the 4G phone lose signal several times a day but show 3 bars. There is no data connection and the phones cannot make or receive calls. If they are reset or toggled between 3G & 2G then they work again for a while.
This behaviour happens at work and at home. No other phone user has this problem - there are a few iphone & non smartphone users who gloat constantly
Anyone else suffering as badly as us?
All fine here. Sim free phone under TM contract.
Under carrier it says either TM/Orange never EE for some strange reason.
Exynos SIII; CM10.1
why not post in the help section?
Try different modems and make sure ril/modem match
Here's your answer: EE sucks!!
Lots of people reported signal loss on many different devices, I'll blame EE not S3s.... I've got one of my phones on Orange and since EE showed up, I'm experiencing signal problems as well. Many times people trying to call me, my phone shows full reception but is unavailable and voice mail kicks in!!!! It's annoying but this behaviour is a Network fault. Nothing to do with phone imho.
The only thing you can check is Baseband version (modem) of all phones and compare to the one which works fine. Maybe all except one have wrong modems installed. Unlikely but can happen
Next time use Q&A section to post your problems or questions..

Has everyone changed their APN to 'everywhere'? No signal problems here in the south - getting four bars, H+ and 12Mbps data speed.
I'm in the south also, no problems here, in fact excellent!
I get bandwidth issues and signal drops. Been on orange & tmobile for years and it only became an issue with the arrival of EE.
Most of the time the signal/speed is great tho.
I'm north west UK
Worth trying one check correct network settings and two try different modems .
