Hi everyone,
So I have a Canadian Captivate that I unlocked using the one-click tool that later moved to India. In Canada, I tested the phone with various providers (was originally Rogers, tested on Fido, etc) and it worked fine.
On arrival to India, it refused to see ANY providers. I tried two different SIM cards (from Airtel and Vodafone), and the phone just did not get any signal from anywhere. A phone shop said I need to "country-unlock" the phone, but *#7465625# shows all "OFF".
I even tried flashing to a few other modems to make sure. No luck.
What could I be doing wrong?
Thanks,
-pN

Hello,
in Uk a brought a Galaxy-S (T-mobile) and unlocked it. Now I'm back in Italy and I put my old SIM card. The Phone works, except for 3g, edge or any mobile connectivity. I think there is two options:
- The phone is still locked.
- My sim is very old (from 1999), may be no more compatible with 3g.
How do I find out which is the case and how I solve that?
Thanks guys (girls too).
No network
Hi m8
Could you please check your imei number, I did exactly the same.
I bought my sgs on firmware 2.1 & unlocked it via free unlock tool, I then messed with some new firmwares. Recently tried to sell my phone as unlocked but when buyer put their sim in, It shows a signal but no data network connection.
After messing around with different sims i did a check & noticed my firmware is some stupid 04999????
Regards
Mark
What does that mean?? Is it related to IMEI somehow?? What should I check about it? How do I fix that? I've 2.2 by the way
Hi all, great forum, I've learned quite a bit from just reading all the threads but I have a headscratcher I couldn't find anything on and hopefully someone can answer this as I'm losing my mind trying to figure it out.
I have a Telus Milestone which works perfectly fine with CM7 RC12 on the Telus network in Canada. Every time I travel to Europe or other places it just won't connect to the local network, just emergency calls.
I tried every single baseband in AOR 3.3 but nothing works. I also tried different roms (Cronos X 1.5, FroyoMOD 2.9.1, wiping phone, factory reset, etc.
Even tried the Moto Defy baseband switcher with no luck. AFAIK this phone is capable of 850/1900/2100 bands.
Really appreciate any help!!!
Well, according to this - http://www.howardforums.com/showthread.php/1641030-Does-the-Telus-Milestone-support-2100MHz-3G - Telus Milestone should support European frequencies, but not 2g and it have same hw like MM for Europe.
Some time ago I was a TelusLite rom for Milestone user and it was working well with 2g and 3g after change to Germany baseband (in Poland). Without baseband change it was only working on 3g.
Maybe you need to flash some European-compatible rom (eg. FroyoMod/CM7) and then try?
Thanks for the quick reply.
I tried changing to Germany baseband which should work but it doesn't. In my case I'm trying to connect to Orange Romania which uses 900/1900/2100.
I did try FroyoMod which is Italian if I'm not mistaken, it was developed by 89luca89. Also tried different flavours of CM and Cronos.
It almost seems as if I have to unlock first or maybe Telus is blocking my account from roaming... is that even possible?
I've ordered an unlock code from cellunlocker.net, hopefully after unlocking I can use a local SIM and see if it connects.
Thanks for the help!
Hm. It is strange that it doesn't working on every rom.
Maybe Telus don't have an agreement for roaming with Orange Romania? I think that it is a problem with one of the cell operators, not with your phone.
Good luck with local SIM
Yeah, strange indeed.
I doubt it is Orange RO as I tried it in Paris, France last week and it wouldn't connect to any network there either, Orange, SFR, etc. A couple of months ago I couldn't connect to Cubacel either. I just figured the commies don't like Canadian smartphones. LOL
I have a feeling Telus has my account locked from roaming. I'm praying the local SIM will work.
Thanks again!
Well, just as I suspected, Telus must have the SIM locked from roaming. The unlock code from cellunlocker.net worked like a charm. Phone connects to local Orange RO network, full 3G data connectivity too.
It's good news I'm happy that you managed it to work.
Looks like Telus don't want you to use other operators. But there is no impossible things
Hello guys! I've been reading these forums for a long time, amazing what you guys do in here
Here is my problem: I live in México, and I traveled to USA for summer vacation, my mexican mobile phone carrier uses 850mhz (TELCEL) and when I went to USA it was using ATT's network.
So everything was working fine, but when I returned just before I was about to cross the border, it stoped working!
It has a message that says ''Emergency calls only'' where it's supposed to say ''TELCEL GSM'', so no internet, no calls, no messages.
I was using Froyo on my phone, and thought of doing a reset to restore factory settings on the phone, but it did not work :/
Then I updated my phone to Darky's Rom 10.2 (Gingerbread) and it's still not working!
When I go to Settings>Wireless and network>Mobile networks>Network operators I can see that my carrier is available to select, but when I try to, it gives me a ''Unable to connect. Try later'' msg.
It is really frustrating because I depend on my phone so much, mainly because I share my 3G connection to my laptop for school's work and stuff.
There's one weird thing though, I unlocked my phone, and placed a MOVISTAR(1900mhz) SIM card on it, AND IT WORKS!!!
But the thing is that I don't have internet on that SIM card(is prepaid and it's EDGE, not 3G), and on my TELCEL SIM card I have a contract to complete (still a year to go).
When I put my SIM card on someone else's phone, it works like a charm, but if I try to put a TELCEL (850mhz) SIM on my galaxy; just says ''Only emergency calls''
What do you guys think happened to my phone? I would really appreciate your help.
flash a new modem... one that contains more frequencies enabled.. any bell or telus will do.
UGKC1 modem should fix your problem.
It did not work, should I keep trying with other modems?
you can.. jk4 or jl2 are other modems with 850 and 1900 enabled... maybe your problem is different then I thought... but it sounds like your modem... maybe try unlocking your phone? if you can connect to wifi download sgs unlocker pro (paid app) in the market to unlock, your phone also needs to be rooted. are you using the i9000T? that may be different problem altogether...
edit: sorry I see you said it is unlocked... just doesn't sound like it...
a) modem related (ugkc1) should have fixed that
b) SIM carrier not compatible to phone (unlock phone to fix)
c) Busted SIM card, check in other phone
d) make sure phone option is set to Automatic CDMA/GSM
sounds like you checked everything I would check....
does your 3G work... make sure your VPN is setup to your carrier
maybe imei got blocked...? only way around that is to get provider/samsung to unblock
Hey have you solved this, I have the same problem

I encountered exactly this issue today.
I wanted to test the data speed from another carrier (same band: 850 Mhz).
It did not detect the data network so I thought "never mind", and inserted my SIM I always used (over 10 months).
It now says "emergency calls only", and when I click to check Mobile Networks in settings, it says no SIM detected. When I insert my SIM into another phone it works.
I tried a few other radios, but it doesn't work.
So what to do with an issue like this?
I have no idea i have tried every possible combination of everything from flashing modding but if a manually choose network it says sim not allowed to register on this network if that helps ive rung both three and samsung with no help x

I need for the 850 Mhz band, and so far only 2 are confirmed to work on this band.
I have tried both, and several others now as well. Now I would settle for SIM card detection and GSM signal...
For example I have tried
Telestra-modem.zip
JK3
JPZ
HKC1
JK5
JPE
None work even for detecting the SIM card.

Yep, same here... the zip says JQ2 but the inside is JQ3, which I assume is the latest release Anyway, for me it works a charm.
I just sent my 10 month old Tab for repairs.
The Samsung service center people and carrier staff were all very surprised it didn't work.
Let me explain why. When I insert a SIM card from carrier #1 on 850 Mhz band it works. I then insert a SIM card from Carrier #2 on the same 850 Mhz band, and it does not work.
I insert SIM #2 into another android phones (tested Galaxy S2, S1, galaxy nexus, and a "dumb-phone")... the SIM works.
Then we tested SIM #3 from the same carrier of SIM #2.... SIM #3 works. Very confusing.
Conclusion.... the SIM card slot is "broken". Nobody knows why some SIM's work, and others do not.
Result. 3-5 days wait for a repaired device or a new device.
Edit: And big thanks to every android custom rom developer out there. Your hard work and diligence allowed me to revert back to a Stock 2.2 ROM, including locked bootloaders, before sending back for repairs.
This is bad news...
I got a call from Samsung and they explained to me that they had to change the entire mainboard. Naturally they didn't have any in stock, and had to order it from Korea, and I'm out of a Tab for 3 weeks.
Hi guys, i have just bought a Samsung Galaxy S3 LTE i9305 it was advertised as unlocked and it is to a point but wont get a signal with my Three sim card. i have tried vodafone and EE sims and they work fine. i've re-entered the settings for Three in mobile networks settings but still nothing, just says emergency calls only. can anyone help?
