Can't use 3G after unlock - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I've rooted/unlocked a Samsung S2 i9000, everything is perfect but the top 3G (data access) on/off button won't do nothing.
Even If I go to the wireless&network configuration and activate the data access, I have no access at all.
I'm using a pre-paid card (and was working ok on another mobile) from Lebara in the Netherlands
Anyone knows something on this?
Thanks

Which is it, S2 or I9000?
Questions do not belong in general.

I9000 is Galaxy S
I9100 is Galaxy S2
Which one do you own ?

Did u try reset APN in settings?

APN app for Honeycomb

As mentioned in this thread (http://forum.xda-developers.com/showthread.php?p=16244994), I am unable to save APN settings on my Samsung Galaxy Tab 10.1v, which is why I am looking for an app for Honeycomb where I can insert APN-settings (like APN Manager for the phones).
Nothing on the marketplace, so can someone maybe port it to Honeycomb?
Thanks in advance
i just purchased my Galaxy Tab 10.1v, and got me a data-only mobile internet SIM
but now i can't save the APN :/
so i would be interested in this as well!
something like this you mean?

Yep, but my Sim is stuck and I can't remove it, so this thread has just become useless for me

Can S5830 be used in canada with FIDO ?

Hi all,
i bought a unlocked Galaxy Ace S5830 via amozon.ca for my friend in Toronto, and the phone has current following firmware: (it seems to be for region european)
Pda: s5830XWKPT
Phone: s5830XWKP7
Csc: s5830OXFKP3
Android 2.3.3
GINGERBREAD.XWKPT
Kernel 2.6.35.7-perf-CL469288 [email protected]#1
and my friend has a sim card from fido in the phone. And he has activated his data plan with Fido, but the phone just can not use 2G/3G.
Fortunately the phone works fine with voice phone, WIFI etc. except mobile data network. I'm afraid that the firmware of the Phone and CSC
are not fit for canada. As i searched in this forum, i found the information about Galaxy GT-S5830D with firmware S5830DTLSKI4,
So my questions are:
1: is it really not possible to get mobile network working in canada with current firmwares ?
2: can then the GT-S5830 be flashed with the firmware S5830DTLSKI4 of GT-S5830D?
3: Is the firmware S5830DTLSKI4 only for Network of Koodo/Telus, or it works also for FIDO?
thanks a lot for your helps in advance ...

only data is not working??
have you activated data in settings and checked apn settings??
settings might not be properly recognized
Yes, only data is not working. So i'm not sure now if it is modem issue or just APN setting issue. Does anyone here use S5830 from canada? which modem firmware do you have?

Hi, I am not sure if this will help you, but I have a Galaxy Ace GT-S5830D originally bought on the Koodo Network, but I unlocked it and am now running it on Fido with a Fido SIM card.
I too had problems connecting to data with Fido after unlocking, but you must enable data roaming for it to work.
Settings > Wireless and networks > Mobile Networks > Data Roaming
Also ensure your APN settings are set right.

Thread about enabling data roaming... seems to be a thing about Fido being on Rogers network:
http://forums.fido.ca/t5/forums/forumtopicpage/board-id/Smartphones/thread-id/3502/page/1
Enabling data roaming fixed it for me, but I am not sure if this will help you since you have a GT-S5830 while I have a GT-S5830D.
Hope this helps.
Hi, thank you so much for your helpfully information. With your information my friend can use the data networking provided by FIDO now with his GT-S5830! THANK YOU, THANK YOU, THANT YOU!
But only connects with 2g right?
I use my SGA with the Rogers networks and I can only connect with 2g data. My understanding is that 3g is only possible in Canada with the SGA on the Mobilcity and Wind networks due to the limited frequencies the SGA can use for 3g.

I was told my Unlocked SGA couldn't run on AWS networks like Wind and Mobilicity.
As for only 2G? Umm... who told you that? I honestly don't know about the frequencies and such, but my 3G icon in my status bar lights up all the time and honestly, my SGA downloads speeds are faster than my Nexus S which was bought from FIDO.

[Q] how to select network operator manually?

yesterday i brought AT&T's Samsung galaxy s2 SGH-i777(locked) and i unlocked that mobile through cellunlocker.com to pay 11$ for unlock code..they sent 8digit code..its works perfectly...after that i put my IDEA cellular INDIA SIM card on it..its showing some signal..but i am not able to make a calls..its saying network not registered.....after i restart the mobile it took "T-Mobile" network for a moment and lost..after that nomore connection.
when i go to wireless and network/ mobile networks/ network operators only thing which comes written is "DEFAULT SETUP" and that is greyed out. (when i tap on nothing happens).
also when i change back to my old AT&T sim, i am not able to access that greyed out area.
can someone please guide me through it..??
i am new to android phone..currently ia m roaming with T-mobile network in USA-Oklahoma.
my nokia e-5 working perfectly when i switch back SIM on it.
Please help me to how i got signal on my galaxy s2.
trouble shooting done
mobile not in flight mode...wifi working fine...2nd time i removed battery for a while and restart.it tooks network for 2minutes ..i make a blank call to other mobile...after that no signal...
below is my mobile information:
Model no - samsung-sgh-i777
android version 2.3.6
baseband verson- i777uckk6
kernel verson - 2.6.35.7
build number - gingerbread.uckk6
STATUS-
Signal strength- -101dBm 6asu
mobile network type- GPRS
service state- out of service
roaming- not roaming
mobile network state- disconnected
IMEI- 35805504356xxxx
IMEI SV- 03
First thing's first: never post your IMEI. You should take that down ASAP.
Secondly: I have no idea what's wrong with your phone, but our phone is free to unlock. As in, you didn't have to pay anything, all you had to do was root and use an app from the Play Store.
Thirdly: I believe you cannot select the network operator while on a stock ROM (either 2.3.4 or 2.3.6), no matter what you tried. You'd need to flash a custom ROM to do that (not entirely sure, someone correct me if I'm wrong).
Fourthly: Note that the I777 doesn't have the hardware to use T-Mobile's 3G/4G services. You'll only be able to run on Edge, period. There are no workarounds.
Lastly: To fix your problem, I would recommend starting over. That is, wiping all data/caches and flashing back to complete stock 2.3.4. Then root it, and use the app I mentioned before to unlock. Flash a custom ROM after that if you still want the ability to select the network operator.
Read all of the links in the sticky if you want to follow any of the suggestions I made. And I mean, read all of them before you do anything to your phone. You need to fully understand everything you are about to do before you do it.
P.S. Please hit my thanks button if I helped you. Good luck!

Read only posts and threads here. Other websites have outdated info. No ROM is best, try them all yourself. You need to better understand what a ROM is, so search for that. Keep reading, I told you it will take you several days. I won't spoon feed you forever.

[Q] Unlocked Koodoo SGS2 no data on Fido

Hi,
Not sure if this has been posted, but I did a search and was not able to find any thread on this.
I have a Koodoo Samsung Galaxy S2 (SGH T989D) that I rooted and unlocked. When I put my Fido SIMin, I can only make voice calls and no data connection, none of my cellular data app./browser can connect to the internet, WIFI is working fine. I used both the APN drawn from the SIM card and manually set them according to the Fido forum, and both doesn't seem to work.
I've enable Data Roaming and still no luck, has anyone sucessfully unlock a Koodoo Samsung Galaxy S2 and got the data to work on the Fido network?
Any help would be much appreciated!!
Thanks in advance.
did you talk to your provider, they may have enable settings on their server.

Thanks
