Not connecting to international network - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys. I'm having a problem with my gt-i9505. I flashed a custom rom a few weeks ago (Paranoid Android), and last week I traveled to Spain. I live in Portugal and everything works fine, but in Spain I didn't get any network or data roaming. I went to the network selection panel in settings and no network was found. I was 3 days in Spain with no data/calls, and as soon as I got back to Portugal, I got my signal again and all was fine.
Does anyone have any idea of what might be wrong?

Hi ,
I guess you checked that Mobile data was enabled also data roaming?
Did you tried different bands like GSM?
Do you have roaming in your contract in Portugal?

Yep, both mobile data and roaming were enabled.
Different bands I don't think I tried... may it have been that?
As for my contract, I called them and they say everything is ok on their side, and roaming should work fine.

Hi ,
Is strange if roaming was available ( data and calls) you should had been able to connect , one thing that does not sound ok is that you did not have any operator available , even if you do not have roaming you can still see them.
Did you ask in your rom thread?

Same issue here with gt i9505, only get signal when I'm very near to a high frequency tower and not at home, and when I'm at home searching for network it just stops searching and doesn't find any network operators

Forcing G1 to Roam

I'm going camping this coming weekend to a place in the mountains that tmobile has very poor coverage in. I was there last month and discovered my friends at&t phone had full service while my g1 showed service, just didn't show any bars and other times only showed one bar. Calls with my phone were flacky and dropped out, his worked perfectly. Is there a way to make my phone switch to roaming on at&t?
I have a national plan on T-Mobile.
I'm running Cyanogen 3.9.5
Thanks!

Should do it automatically. I saw my phone do this the other weekend when I was travelin. My phone showed ATT, Corr Wireless, and some other service and certain points.
The tmobile signal is just strong enough to keep it from roaming there. I was hoping it would switch automatically but it never did. I know the phone does have roaming ability, i've seen it switch to roam and work fine.
I would assume then just change your APN settings.
you can try manual operator selection, by going Settings > Wireless Controls > Mobile Network Settings > Network Operators > Search Networks then select whatever network you want to use
Hi.. I'm using CyanogenMod 3.6.8.1 on my HTC Dream and I've got the same issues with roaming. I've travelled to 3 countries last month and I had issues with connecting to GSM network.. There was error message that my sim card cannot work with specific networks.. I've tried to use auto connection and I've tried also to connect manually to specific networks, but with the same result. I've tried also rebooting and removing the battery... Problem disappeared after few hours... I had this issue in Austria, Hungary and Turkey so it's not operator/country specific. Problems doesn't exist on different cell phone (Nokia). Everything works fine after powering on the phone.

serious issue on SGS-2 and 3g internet

i own a samsung galaxy s2 ordered from uk,
everything working fine except for this serious issue that i have been trying to resolve till now.
i have a monthly internet subscription from my carrier and it always been working fine on my iphone ( i mean here connecting through the 3g network ). but in the S2 .. i have to use Edge to be able to access the internet ( the mobile network mode must be set to GSM only ). whenever i switch the network mode to GSM\WCDMA auto , the 3g icon appears but when it tries to connect to internet, the phone automatically switch to Flight mode and i loose the network signal. and this happens all the time. till now i am only able to connect to the internet by switching the mobile network mode to GSM only which only uses Edge network .
i have tried every possible thing to resolve this issue but nothing worked for me. please help
What country are you in? What carrier are you on? What bands do they use?
location location location.
Where are you from?
And what frequency does operators in your region operate.
just curious, have you tried hard/factory reset?
i am from saudi arabia and i am using Mobily network.
mobily is using HSDPA network as well as Edge network.
i did a software reset and still the same issue.
phone information:
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
crazy idea - is there any blocking going on in SA or with that carrier? Have you used another not carrier supplied smartphone successfully on that network?
I have been always using their 3g network on my iphone. And still there network only on edge connection on the s2. What i have noticed is that the saved apn sometimes shows up and sometimes disappears

Hi, very similar issue here.
For this four days since I have got my GS2 everything was just fine. The data connection and 3G speed was great. Yesterday, all of the sudden all got crappy. Could not display any web pages. It starting to display page but after few seconds pop-up window appear which say "Data connectivity problem. The server failed to communicate. Try again later"
Interesting that my gmail, market, xda app working fine as normal.
I'm in Ireland on O2 now.
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
Can someone help to solve the problem, please. Is it possible that something with the hardware is wrong? Broken?
I'll perform the factory reset and will let you know.
i just managed to flash my device with the latest EXE1 dated May 3.
and i am still facing the exact same problem.

I have same issue, and for Ihrrob, your other application are working fine because what i noticed on my mobile that 3G & 2G connection is there but not permenant that's why WIFI hotspot always disconnect and VOIP applications are not working.

You are right the 3G/2G connection is there but not permanent.
If I press the Internet icon the home page, which is 'Google' appears (sometimes) immediately. I think this is because the page is very light. If I try to open a regular page it loads 1/3 of the content or nothing.
i just hope it is a software bug not a hardware problem
Type on the dialpad *#*#4636#*#* and force the phone to HSDPA only on the dropdown menu. This is a hidden menu on the phone.
Isn't this carrier related?

Unfortunately not.
I have spoke to the rep in the store. They reset all settings for me but it didn't help.
Just to double check if he wasn't wrong I've put the sim card in to my N900 and all data worked fine.
Bad, bad...

I'm on Mobily network in Riyadh, and 2G/3G is working fine for me. I stay on 2G most of the time to save battery, but have tested 3G and got around 3mbps.
I have the same Baseband, Kernel and Build number (rooted)
Are you using "Market Enabeler"? It can change your APN settings, and you need to restore the provider setting.
just rooted my device.
still same weird issue.
issue again: simply whenever my device tries to connect to H+ , the device automatically enters flight mode and automatically disable flight mode so that the signal bars come back without H+ and when i check back the saved APN i see nothing there ( thought i was there before ). and this strange behavior disappears when i switch the mode from GSM/WCDMA auto TO GSM only .. after i do this the device connects regularly to Edge network and i can browse the net.
so basicaly for me i will be only able to use the device on Edge instead of HSDPA or 3G.
im really hoping for help from here because i don't think i will find any help outside of this expert community.
regards
try to make it on obligatory 3G (WCDMA only) and check if the problem still there ..
still same problem juffo
i have noticed that another post are poping up talking about almost the same issure.
i hope a new firmware will fix this

No 4G/LTE with SM-G935FD

I have a new SM-G935FD purchased in the UAE. The software version is MMB29K.G935FXXU1APD1. The phone has a "United Arab Emirates" section in the About page.
I travel a lot. I generally use a local SIM when I am in a country for some time. Right now I am in France. I am using a SIM from Bouygues Telecom but I have no 4G/LTE service at all. The phone is connecting at H+ and also at 3G, but it is not showing 4G/LTE at all.
I will be in several other European countries as well as the US soon. I specifically purchased this phone because it has all the LTE bands for the countries I spend time in. This same SIM does give me LTE connections on Bouygues when I use it in my old phone (a Motorola X 2nd Gen). I had expected this phone to just work on LTE everywhere that I typically go.
I have looked through these forums and see a thread or two about others with LTE problems. But no clear solutions.
I have tried various apps such as LTE Discovery (no luck) as well as 4G LTE Switcher - using that if I set "LTE only", I get no service at all, and then have to reboot the phone before I get service back.
Is there something I need to do to get LTE?
Thanks.
Have you put the SIM in the correct slot?

Yes, the bottom slot. The SDcard is in the top slot. The SIM is showing in the phone as "SIM1".
Strange. I have a G935FD and it works with LTE no problems. I've used it in Singapore and Indonesia, with different SIMs and all work.
In Settings - Mobile Networks - Network Mode, it's set to LTE/3G/2G?

Yes it is. I've tried changing to one of the non-LTE modes and back, but no change.
In the About device / Status / SIM Card status page, I see Mobile network type as UTMS. Shouldn't that have LTE and, if so, how do I change it?
Mine says the same, but I'm only connected to 3G at the moment, so I don't know if it's normal it not. I have a 4G card in, but I'm out of my area's 4G network range.
Edit: Actually I was connected to my wifi. Now I'm connected to my 3G and it says HSPA+ now
Edit again: Ok, so my phone is jumping between 3G and H+, which is what's changing.

Ah, mine is doing the same. I see Mobile network type jumping between UMTS and HSPA+ if I watch for a while. Obviously that field is a status field, not a setting field.
Thing is, I am in an area with full LTE coverage.
At least you seem to be confirming that this should work. Still need to figure out what the problem is.
I have the same Problem in Spain. With a Vodafone Card I dont have 4G Connection (The same card in a the Galaxy S5 of my wife works with 4G). But with a Yoigo Card I have 4G Connection. The software version is MMB29K.G935FXXU1BPH6. The phone has a "United Arab Emirates" section in the About page too. Any Idea?
Thanks

LTE does not work anymore (G600K)

Hi All,
I bought this LG G6 (G600K) from HK a month ago. It was working perfectly until few days ago when the LTE stopped working. In the notification bar I can see LTE, but there is no data going through. E.g.: messenger shows "Connecting...". Basically no 4G internet any more. So I did my research and these are my findings:
If there is no LTE coverage, the phone switches to 3g and it works - so the problem is only with LTE, but LTE is everywhere nowdays
In this Korea Telecom ROM there is no way to configure to only use 3g (CDMA only), not even in hidden menu - this could be a remedy, but would not solve the issue
Wifi also works
I did Factory Reset twice (also Network settings reset), did not help
I waited for an update from KT, maybe contains a fix, but did not help
I went to my operator (TELENOR Hungary), and they have checked my subscription, and they said everything is ok, but they can see that my phone does not connect to the LTE system.
I tried my SIM in an other phone, and LTE works perfectly
So based on these facts, I can't think of other than the phone has a hardware issue. Do you have any idea how can I investigate further?
Thanks for any suggestion.

Have you made sure data roaming is turned on as you have Korean model, I had to enable data roaming to get mobile data as the device thinks that's exactly what it's doing.

Hi, sorry to hear. I could not solve yet. I went to the 3rd line support of the operator, but they say everything is fine from their side. So I'm waiting for a custom ROM, or I will change my operator. If you can, send back your phone.

Well i just found temporary fix for grayed out data roaming..this method worked to me
download quickshortcutmaker from playstore open app and switch to normal search find roaming click on roaming - global roaming - create... you can enable data roaming from there..
And for manual network switch LTE /3G : quickshortcutmaker - normal view - network -networksettings global
Hope that helps
Sorry for my bad English..
Wow, thanks. This is working as a remedy. You are the hero of the day

Any way to get 4G/LTE, Please Help!

Hi everyone. I have a Leeco Pro 3 X727. I am on Firmware 20s I am having issues to get 4G/LTE signal.
First thing, In my City there is 4G signal, even a couple a days ago I went to my carrier and change my Sim for the newset, just in case.
The last Rom where I had LTE signal IICR was AEX5.4 around May's days. After I changed to CDroid, then to DotsOS... Whatever all I can get its H+ signal. Couple a days ago I change to Carbon Rom 6.1 (Oreos) and the first install, in the configuration I get LTE, but after change to Wifi for finish install all apps, I cant get LTE again. I flashed back Dots, Cdroid and I am now and AEX5.7 and I I have the same issue, just 3G/H+, not LTE or 4G. Also, after flashing firmware 20S I get LTE signal for a While so I think that is not the problem...
I tried almost all APN setting and Nothing. Chang Rom, change Recovery, change Kernel... Nothing just 3g/H+.... My friends with same Carrier have LTE signal...
So, is there anything I can do...? Flash any app, setting?
Help please.

Only use the X7272 5.8.20s firmware - Then you should be able to get it with the correct APN and setting
Don't choose Global, you want the LTE/GSM/UMTS/CDMA setting. If you are still having issues, use the program LTE Discovery or Network Guru.
There are Magsisk
What network are you trying to connect to? What country are you in?
Go to Settings -> Backup & reset -> Network settings reset -> RESET SETTINGS

Nothing. Still "Orange 3G" and conexión icon show H+.
Honestly, I'd say something is wrong with your phone or wrong with your cell towers. The only LTE Band that Orange/Altice supports in DR is B3 (sorta strange that there's only one band, but for a relatively small country I suppose it doesn't matter) and the LEX727 and LEX720 both have band 3, as well as the only GSM(3g)/UMTS(4g) bands that Orange/Altice supports (that being GSM:1800/1900 and UMTS B8 (900GSM)) At first my assumption was that Orange/Altice was a CDMA network, but as far as I can see, there are no CDMA networks in DR!
Edit: download the speedtest app, and see if you're getting the same speeds as a phone that shows it's connected to LTE. If you are, there's no issue besides the phone reporting the connection wrong. If you're slower, though...

Maybe the problem is Orange Altice. The 4G coverage its very new in my city. I al ready tested speed and its 3G 5mb/3mb

Oh! I think I know the issue! When I looked at Orange's website (trying to find network specs, which strangely for a network that supports BYOD, they don't have listed, or at least I couldn't find it) I saw that they have subscribers pay for data, as is standard practice in the US (where I live). But the thing that caught my eye is that you also pay for speed.
So... Let me take a guess here. You pay either RD$1499 Or RD$1349 for their 5mbps unlimited plan?
Basically, my assumption is that if you're paying for one of their lower speed tiers, they put you on a 4g or 3g network to save LTE bandwidth for the people who pay more than you.
Tell me if any of this sounds familiar... I feel like I may've found your problem!

Mmmmm suspect ... actually I have an even lower plan, RD $ 580 (USD$12) and I only use the data when I buy additional packages ... Most times I use Wi-Fi and just use Data when I am not at home/job and the 3G its veeeery looooow speed... Thank bro, that could be the problem.
