I have a Samsung Galaxy SIII Mini (I8190). The version i have supports HSPA 900/1900/2100 Mhz.
However, in Jamaica the 3g/4g frequency is 850MHz.
How can I modify this device to access the 3g/4g out here in Jamaica?
Please help...

Hi guys.
I didn't know where to post and I have few questions on my Galaxy SII I bought from Korea and brought to USA.
I have KT's 250S galaxy SII and I'm trying to use it for At&t. I tried to put my At&t sim card in and looks like it is getting some connection. I was able to make a call.
However, looks like it's not getting any 3G connections. I heard there is some modification on the network I need to change to get 3G. Could you please let me know what should I do?
Thank you,
Andy

Go to the miui thread in development section and use the apn from there. That should theoretically fix your issue...

From the third post down:
Code:
<< Korea Galaxy S2 Network support >>
Double band UMTS 900/2100
Triple band GSM 900/1800/1900
<< EU Galaxy S2 band Network support>>
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
AT&T and International (I9100) GSIIs support the same bands, which is why I9100s work perfectly in the US. Your device is completely missing support for the 850 MHz band (first device I've seen in years that wasn't quadband GSM other than dumbphones) and also missing support for 3G in the 1800 MHz band.
So you will not have 3G coverage anywhere, and you will completely lose coverage where AT&T uses the 850 MHz band.
I'm going to assume this is the same variant at AT&T in the US, I know the frequencies for 3g and LTE are the same in most other phones...
Hello everyone,
I am thinking to purchase at&t or T-mobile samsung galaxy S3, samsung galaxy s3 mini, iphone 4, 4s or 5 immediately before I go back to my homeland. I know these samsung galaxy S3 and iphone support HSDPA network. My homeland has only WCDMA 2100MHz network. My question is will these galaxy S3 or iphone works on WCDMA 2100 Mhz network. Thanks in advance.
HSDPA is the data connection protocol for 3G networks. WCDMA is what 3G is called, and 2100 MHz is the frequency. You need to look at a full specification list for the carrier variant of the phone you want, and check that it supports 2100 MHz frequency band. You'll see this info and supported 2G and 3G bands right at the top of the specification list in GSMarena. If the phone supports 2100 MHz, then it will work in your country. HSDPA/HSUPA is to WCDMA as GPRS/EDGE is to 2G GSM networks. They are just data protocols. You need to look at the bandwidth specifications.

Hello, i have samsung galaxy note i717 att lte version. I live in europe and my operator only accepts 800 and 1800 mh lte frequencies. How is it possible to enable those lte bands on my galaxy note phone, as it has lte antenna, it should be somehow possible to make phone operate on these frequences. P.s thanks in advance. I will make donation if someone will solve my issue.
