[Q] Change SGS Vibrant T-Mobile to Telcel Mexico 3G - Vibrant Q&A, Help & Troubleshooting

I search overall forum for a solution and i did not found the answer. Here my problem:
I have a Samsung Galaxy S Vibrant T-Mobile. I root the phone and now i have the ICS Passion v10 BETA from neobuddy89.
I have a Telcel provider with an EDGE connection.
I did the *#*#197328640#*#* "trick" to enable the 850Mhz 3G Band. But it did not work, i still have the EDGE connection.
I have the correct configuration in the access point.
In several threads i read that Telcel and T-Mobile bands are not similar. So my question is Can i use a Captive modem (AT&T model) to enable the band?
How can i do that?
There is a tutorial to do that?
Thanks for all your support.!

A little bit late, sorry i don't have an answer for your question
but i have a question for you:
How did you configured internet EDGE for telcel?
I have a Vibrant in telcel, but no matter what I can't have access to internet

[Q] Custom modem or something else for 850mhz 3G on the vibrant?

Hello everyone i Live in Panama and my provider (Cable and Wireless Panama) uses 850mhz band for 3G, i've been searching on the forums but I didnt found a clear answer if it is posisble or not to use the band for 3G on the vibrant.
Maybe with a custom modem, a i9000 port or something else?
Thanks

If you've got a T-Mobile Vibrant (T959); it wouldn't be possible to get 3g on the 850mhz band. The T959 only has AWS(1700/2100)/1900/2100 for 3g. This is a hardware limitation (radio), so there isn't any software fixes that will allow you to be on anything other than EDGE in this case.
IIRC, the Bell Vibrant (i9000m) would get along just fine with your carrier because it has the 850mhz radio.
As far as I know, the Vibrant doesn't have the hardware capabilities for the 850mhz band. Your better off going and buying an i9000, which should work fine.
thanks
Thanks for the responeses, well it looks like i will have to change the phone/change carrier (most likely because C&W Panama sucks!)
i have a Samsung Galaxy i9000...
With Cable & Wireless Panama (+movil) carrier and cant get 3G coverage!!!
Android 2.2 working great!!!
Any idea???
thanks!
The vibrant does have 850mhz. You just have to enable it by using a code in the dialer to gain access to the band selection menu.

[Q] How to Change the modem of T959 to I9000?

I have seen many Thread about I9000 trying to convert T959 modem to use the T-mobile network. What i couldn't find is from T959 to I9000 to make it to the international version.
I have the T-Mobile Vibrant T-959 unlocked with ECLAIR. I know that the network band of this phone is 850/900/1800/1900. i found the result according to Samsung website. I know in another post it was said that it is hardware issue but the hardware is 850/900/1800/1900.
I live in the United Arab Emirates and the network band here is 900/1800 similar to the European or Asian Network. but the T-mobile uses 850/1900 so i couldn't get 3G or any kind of internet connection here, unless i find a WiFi connection. I need the 3G connection on the move.
I want to know is there any way to change the the modem band to I9000? so that i can use a custom rom like Darky which is Stable according to many users.
I would never be using the phone on US T-mobile or any Network in the US.
You might think this Question is redundant and has already been answered but i search every where but it comes back empty.
Your feedback would be highly Appreciated!!!!
I don't think you can actually change your phone's bands.
However, an unlocked US T-Mobile Vibrant should be working on 3G. According to Wikipedia, the two 3G networks in UAE (du and Etisalat?) use the 2100MHz band, which should be supported.
Thanks for the reply, i tried everything but nothing worked.
One more question to ask, what will happen if i flash i9000 rom and radio on a T-mobile phone. Or should i just flash it with a T-mobile rom without changing the radio, and if the sim gets locked I will just unlock?
this is the final question to ask.
Don't know if this helps but I use my unlocked vibrant in the uk, so if European bands are the same...it should work.
You can change roms and I would recommend you should but you can't use an i9000 modem.
Do you have a Sim with a data plan?
Can you text or make calls?

Yes i can make a calls and send Text but no internet connection. I just bought data plan for my sim.
So i Should get Vibrant custom rom not the I9000 rom?
And thank you Guys for your replay, I hope this tread will help other confused users on XDA
I would like everyone to know that it is not good thing to change there modem from T959 to i9000 your phone will brick never do it.
I just flashed a new rom from Trigger 3.2 which upgraded to Froyo 2.2 and i put in the settings for the Access Point and it works perfectly.
So if you have any difficulty accessing 3g or HSDPA connection on android 2.1 just upgrade it and it will work.
How did you conclude you're not on 3G? Do you get EDGE or GPRS internet connection?
So i need the 1800 mhz how can i do?
Flash a i9000 modem and see if it works.

There is the possibility to brick the phone?

GS2 Korean M250K model

Hey guys,
I have searched throughout the forums but have not been able to find a solid answer. I just got a Korean variant of the SG2, model M250K. I reside in Canada and am on the Fido network which is the same as Rogers. Wondering if this is a software or hardware issue. I am on the stock Korean firmware. The phone is working except I cannot acquire 3G data. Is there anything I can do to let it acquire 3g speeds here, Fido uses the 850 frequency. As far as I have read the korean firmware does not use that frequency hence I am getting edge connections. Are all of the Samsung Galaxy S2 phones built the same ie, GSM phones all have the same abilities. Would flashing to another firmware allow me to connect to the 850 frequency. Basivcally is this a software issue or hardware issue. Thanks guys.

Can You Modify Your Rogers Galaxy S2 LTE to work on aws 1700/2100?

Hello Everyone
I don't know if this has been asked before, but I searched and found no answers. Basically, Me and my dad want to switch from Rogers to Mobilicity (which uses the 1700/2100 frequency), so we went to the mobilicity store and tried my dad's galaxy s2 lte (rogers version) with the mobilicity sim card, and the phone didn't detect mobilicity's network (it goes into Rogers roaming mode i think). So I started looking around, and I found this advertisement on Kijiji Calgary about modifying the S2 LTE to work with Mobilicity's frequency. So, Is there a way I can convert/modify the phone by myself to work with the AWS 1700/2100 frequency? I assume the phone has to be rooted first if such thing is possible?
Thanks!
I don't think so as it's HW related.

i have the tmobile version (SGH-T989) flashed to the Rogers radio... and now i'm able to connect to RoBelLus
and when i'm fed up w/ their high prices, I can just flash back a Tmobile radio and go with Wind/Mobilicity
it works for the ATT Skyrocket & Tmobile version of the S2 ... i'm not sure if it will work with the Rogers one... do some research, you should be able to do it
PM me if you some help researching... if i can't get u the answers, i might be able to guide you to the right threads

International S3 on T-mobile giving only EDGE

I have a I9300 S3 international version. I recently Shifted to the US and am not able to get 3G connectivity. I can see only EDGE network. I know its got something to do with frequencies, because I have the APN etc correctly set up. My only question is will it ever work on 3G on T-Mobile? Is it fixable by flashing any modem?
P.S. I'm using Cyanogenmod 4.4.4.
