Problem roaming

Good evening all,
Hopefully someone can answer my question.
Sunday I took a road trip. I noticed that my phone had no service. In the past when I left the t-mobile area my g1 would automatically connect to whatever network was available and the roam indicator would show up.
I tried to manually connect to at&t through the network operators menu. My phone said "Your sim card does not allow a connection to this network.".
I have a rooted g1 running the official t-mobile 1.6 rom. Is this a problem with my rom or my phone or the network. I've tried searching and I haven't found much of a solution yet.
I am in the usa. A lot of the google search results I got were from Europe.

might not have been a ROM issue; just a bug...
Did you reboot or force radio off then back on?

I have the same problem and yet no luck to resolve this.

I did reboot and enable/disable airplane mode.
Today I switched to the Cyanogen Rom. I'll see if that fixes the problem. I tried to manually switch to at&t, but it still says that the sim card does not allow that. I am in the t-mobile coverage area; t-mobile probably does not allow the use of a different network when their network is available. I'd like to test it out to see if roaming works now, but I'm not taking a drive out to the countryside just to see how my phone works.
I guess this one might be hard for me to test because I am rarely out the the t-mobile coverage area.

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.

Maybe we should ask for replacement...

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

3G connection issues

I'm having random 3G connection issues on my Samsung Focus.
At radndom times 3G connection is lost and the only way to get it working is to turn off and on the phone.
I tried putting the phone into airplane mode, turn off/on data, turn 3G off/on, nothing works, only a reboot works.
Today I checked my email on my phone and it says;
Last updated 4 hours ago
We're having a problem connection to exchange.xxx.com. Try again later.
Last tried 2 seconds ago
Error code: 80072FA8
This error shows up on all 3 emails I have setup.
IE doesn't work, Zune, any app requiring 3G connection.
And this happens at random times, at least once a day.
The phone has the lastest updates and is jailbroken.
One other thing to mention is, the phone is now having the 3G connection issue but i have it theathering to my computer and the internet connection is working while theathered, cause i'm posting this email.
I have no idea what's happening or how to fix it.
Thanks

same with me. are you using another carrier ???
Mine is unlocked AT&T Focus, when I'm using indosat (IM3) carrier, I'm having this issue. I downloaded Network Profile from Samsung Zone. After reboot the device, the network profile still pick AT&T, and I can't change it to my carrier.
Then I tried change my carrier to 3, after reboot the phone, the network profile changed to 3 INA. And after that I haven't got that issue till now.
Not sure what caused this. But when I looked at the registry there's a bunch of duplicated APN settings.

I had a similar issue, Focus AT&T on EU network.
Chevron unlocked and enabled the 3G toggle.
From time to time, I couldn't download from Marketplace or use the 3G connection. That was before I updated to NoDo. I haven't experienced this again since I updated.
To fix that, I used to toggle 3G off and on again after 15-30 seconds.
Sometimes, even that didn't work and I had to leave 3G off. Any lower data connection was working while 3G wasn't.
Speaking of data connection, not everyone is aware that after updating to NoDo, HSUPA is disabled on AT&T.

I'm having the same issue.
I´m using an unlocked at&t samsung focus at my local carrier.
I have this issue a few times a day, and the only way to restore my internet connection is rebooting.
I have noticed that this happens when my phone changes to Edge and goes back to 3G again. The issue doesn't seems to happen every time, but sometimes I lost connection.
Did you managed to solve this?

Same here
Using it with mtvmobile italy
Have to reboot everytime

I was having the same issue, being unable to connect to 3G. Just go the first page after Googling: set att apn. AT&T users should put in the APN, username and password. Hope it helps! It worked for me. =D

I´ve the same problem, here at Costa Rica with my focus which is not unlocked nor jailbroken

[Q] Mobile Data not working

Hello all,
I have resorted to posting here as i have trawled the web for a solution without any luck. Here is my problem hope you can help.
I have a nexus 4 and am currently in Spain. After traveling abroad and not using data roaming i came back to Spain to no mobile data connection. The usual tricks of restarting, toggling mobile data airplane mode didn't work. It was quite frustrating. I went as far as to cancel my contract and go for a prepaid card - Lebara as they have a decent data tariff - but the problem persisted. I have configured the APN, gone through all the restart procedures, even factory reset the phone twice and nothing helped.
Mobile data is switched on. I have the APN set up as needed. However, the H E H+ never appear next to the bars on top no matter what i do. I have ordered another SIM card from a different operator in desperation but it might not be here for another week.
I really hope it is not the phone but now I really don't know. I am taking suggestions...
Thanks
PS one thing I just noticed is that if I download apps from my browser the device is listed as vodafone nexus 4 although I have never been on vodafone. This might have some relevance

Go to the dialer, press*#*#4636#*#* this brings you into new menu. go to the phone information to see to what network you are connected. if you scroll down you can force the phone to use 3g (WCDMA only) see if this work. this seting will change when the phone goes into reboot.
also if you happen to have the "3g bug" connecting to a wlan might help as stated by some users.
For me starting the hot spot function does the trick.

Thanks for the advice endet. I have done this but to no avail. When I switch to WCDMA only in the field GPRS service it says connecting for about a minute and then disconnected. After restart it is directly disconnected. I have toggled between GSM only and WCDMA only and restarted the radio. Played with the other settings in this screen and nothing. Only once did I get brief flash of the H on top but trying to replicate the steps didn't lead to anything.
Starting tethering didn't help either...
Could be something with my IMEI? Or CellInfoListRate?

Note 4 - Not Registered on Network and Doesn't work properly when registered.

Hello,
my note 4 - n910G recently started acting weird. It would register to the Vodafone AU, but if i try to call, it would show "Not registered to Network"
Also, sometimes everything works fine for like few minutes. 4g, calls, sms, everything sim related works. and then it would stop working again. it will still be connected to the network, but nothing works. the mobile data sign on status bar shows that Sending is green, but Receiving is nothing when this happens.
EDIT: Sometimes it wouldn't register at all too.
I have tried, factory reset, changed sim, and even done Device Initialization from Smart Switch, because for some reason, ODIN with re-partition pit was not deleting the data in the phone.
Thanks in advance.

UPDATE: so I can use 2g all the time. it's only 4g or 3g which is not stable. 4g network gets registered fast, but doesn't work most of the time. 3g takes way too much time to register, and works a for few minutes before going down.
Is it the network cable or something else? please help.

Same with me when I am in low network coverage area. In the same place same sim card works no problem in another phone.
I did:
1. Restart device and switch on/off airplane mode
2. Change different sim cards
3. Factory reset device
4. Installed root and custom rom (LineageOs). Problem first time occured on stock rom, without root, knox 0x0...
I am not sure, since I am first time using Note 4 in this area, but I think problem might happend sincet latest update...
I was thinking to buy S8 or Note 8 but after this I am not sure...

Some more update:
When 4g sometkmes works, it switches off the phone completely and have to replace the battery to turn on the mobile. Cannot just press the power button to turn on the mobile after it switches of

So, did you fixed this bug?? I have same thing time-time.... ((

The issue is because you have a US Carrier variant of the Note 4, which isn't designed to work on GSM networks.
