[Q] Network problems with I9000 bought in Singapore, using in Canada

Hi everyone,
I bought a Samsung Galaxy S GT-I9000 (16gb) in Singapore and was using it fine on Singtel's network (signed a contract with them). Now I have moved back to Canada and brought my phone with me assuming that all would be ok to use it with the network here. However I'm having big problems with this one network I just signed up with (Virgin Mobile).
85% of the time I cannot connect to it: voice calls and SMSing won't work nor will the data work on it, the only thing it says is "Emergency calls only". Then at other times everything will seem to connect and work fine - I can make calls and use data.
Virgin Mobile will not support me much because they're thinking it's the phone's problem, if I use the phone they gave me (a lower-end model) it works fine.
Here are some details of my phone:
Firmware version
2 2
Baseband version
I9000DXJPA
Kernel version
2 6 32 9
root (at) SE-S604 #1
Build number
FROYO DXJPA
If I check out the status, it usually says this:
Network
Unknown (switches to VIRGIN when it does work)
Mobile network type
UMTS (switches between that and HSDPA and GPRS)
Service state
Out of service
Mobile network state
Disconnected (switches to connected when working, and even when it's not working sometimes)
I have Network mode set to auto mode (GSM/WCDMA). I've tried to switch it to GSM only but that didn't seem to change anything.
I'm wondering if there's some kind of configuration settings I still need to do with the phone? I'm also wondering if it is the network I'm with right now? Virgin Mobile isn't one of the bigger telcom companies here and I'm thinking that if I switch to one of the bigger telcoms, will it work better?
Something else to add - before I signed up with Virgin I was using my phone with a pre-paid service (called Chatr) for voice only and it was working fine.
I'm sure this phone can support the GSM frequencies here.. can't it?
I also still have the Singtel customizations on the phone. Will it help if I remove it?
Any help would be greatly appreciated!
Thanks a lot!

sorry, wrong category..

[Q] can't switch to 3G :'(

Hi all
I've got a problem with my Verizon S III device
I live in a country that doesn't have any 4G networks ( 3G only )
so i went to "settings">"more settings">"mobile networks">"network mode"
there i tried these:
Global witch doesn't connect to 3G
LTE/CDMA witch gave me that my SIM have "no service"
GSM/UMTS witch didn't connect to 3G also
so if anyone would help me on how to connect to 3G network I'd appreciate it

Galaxy S6 Duos Network Issue

I need to solve an issue pertaining to my Galaxy s6 duos. The problem is that sometimes my phone's sim 2 wont work, although it is registered on the network but it won't make a call or send a message neither would it receive a call or message. After i put the phone in airplane mode and switch it back online,then the sim2 starts working. Please help me in solving this issue. What could be causing this problem?

Hmmm set sim 2 only to 2G network and check if it losse connection... (I suspect when phone leaves a 4g area and it has to connect to 3g sometimes stuck at searching ...)

I have an issue that whenever i use mobile data on sim 2 it connects to 2g. I need all the time to go and change from 3g/2g to only 3g then back again to get 3g working. Also noticed that if 3g is not in range it switches to 2g but when its in range it does not automatically take 3g.

HELP!! 3G Mobile Data not working. Somebody please help..

By default the Network Mode is on LTE/WCDMA/GSM (Auto) mode but when I switch on mobile data, nothing shows up, no data connection. And sometimes even no voice service, it shows "emergency calls only".
But when I switch to GSM only mode, EDGE connection shows up (which is normal), Internet goes normal but very slow with EDGE connection (Sometime GPRS).
I tried to swap SIM with my friend, and their SIM works fine with my phone under LTE/WCDMA/GSM (Auto) mode and I do get HSPA and HSPA+ Signal. (Network provider setting changed to their network provider)
I contact my network provider and they said my SIM has no problem, they did insert my SIM into their device and found no problem with my SIM on their device, they get HSPA+ signal with my SIM. And they ask me to take my phone to check for hardware failure.
I checked the APNs and network provider setting, reset back to Stock ROM and clean install my ROM several times, still have no luck
My subscription do have HSPA connection and has been using it for months at the same location, but now it just stay at EDGE and GPRS only.
Is that really a hardware problem? Or could it be SIM problem?

I have exactly the same problem! Same ROM as well. Update to various CM13 releases, factory reset to stock kernel and rom but nothing helps.

Network Issues

Hi guys.
I have been using the Honor-8 for over 6 months now. All of a sudden i am facing this really unexplained issue with my network.
I am able to make calls, send sms, use data 4G etc. but not able to receive incoming calls or sms. Sometimes calls get through but most of the time it says my number is not reachable or out of service.
I have shown my phone to my service provider. They did a network reset from their system for my number and on my phone too. It did not work. Then i did a factory reset on my phone and still it did not work. Later i even replaced my sim with a new one on the same number. This too did not help.
When i put in my sim onto another phone it works perfectly. Also when i use a different sim onto my phone then i dont face any such issue.
Can someone help me solve this issue please.

Before this i have two nova 2i that sudden no service and couldn't to connect to any network at first.. without any online and google search for a guide i strugle at first but then i found a way to connect my mobile data...
1. first if u are using sim one for data switch it up to sim 2 in setting and disable ur mobile data
2.u must switch the sim 2 network to gsm only in mobile network setting
3.now swipe to ur notifications bar and enable ur data connection after successfully connect to 2g network click on the 4g icon at ur status bar .. walla a internet connection successfully been initiated...
4.Repeat all the step after that for sim one if u want to use sim one as ur data sim
5.install huawei tweaker apps from playstore then enabled 4g network only from the apps do it for both sim if u want ur sim to never lost signal permenently.
***Important note if u are changing to other simcard or u format ur phone to factory settings u have to redo all the step again****
