Samsung galaxy s duos 850mhz 3g - Upgrading, Modifying and Unlocking

i bought a phone recently model samsung galaxy s duos GT-S7562 FROM INDIA. UNFORTUNATELY IT SUPPORTS ONLY 900/2100 MHZ 3G CONNECTIVITY IN MY AREA WHERE WE HAVE ONLY 850MHZ 3G CONECTIVITY AVAILABLE . i wonder if there is any means through which i can have access to 850mhz 3g network using the same phone.

I would love to know this as well.. Is there a way to change 3G bands on these phones ?
EDIT : I found that there is a 850/2100 variant which known as the GT-S7562L.
Firmware for this can be found at http://www.hotfile.com/dl/185519733/98e5342/S7562LVJALK1_S7562LZTOALK1_ZTO.zip.html .
Would flashing my phone with this firmware change the 3G bands to 850/2100 ?
How likely is it to brick my phone ?
Thx guys.. hope someone can help...

I'd like to know this too

Can N7105 use Canada LTE?

Hi All,
I am using a N7105 on Bell Canada network. Seem my phone only max. on HSPA+ not LTE. Base on I am reading some information from internet. Bell is using 1700/2100/2600 Mhz for LTE. My phone only able pick up LTE 800/1800/2600 Mhz. My question is shouldn't my phone work on Bell LTE network on 2600 Mhz?? Also does anyone out there use N7105 and able to use LTE on Rogers/Bell/Telus???
Thanks
PC
wow really no one use N7105 in Canada???
It will work but generally performance would be poor inside buildings or in areas of interference, due to having only one compatible band instead of two.

I have tried even outside on the street still not getting LTE:crying:
7105 is international, international usually mean European, Australia etc, ie NOT north American region. They will have carrier specific versions for bell, telus, robbers, wind etc

This is stupid they don't follow the other country
So which model name/number is the Canadian Bell one? I'm thinking of buying one in Calgary, but I wanted to monitor ROM development before I got one, so which forum should I follow for the Canadian one? I just guessed it was an N7105, but apparently it's not!
Edit: Nevermind, found it on Wikipedia. It's SGH-i317M and seems roughly same as AT&T, I guess I'll go to that forum!
Although I don't know anyone that has a N7105 on LTE in Canada, I've seen people use LTE with a I9305 (with the same LTE bands as the N7105) in Vancouver at least, so technically your phone should work. It may be that your area doesn't have the 2600Mhz spectrum.

Ah so i called Bell they told me they have 2600 Mhz but you never know. Cause Bell tech. support sucks
N7105 supports 2600 mhz radio frequency, but a respective modem file need to be flashed for it to work on LTE network.
I had Note LTE i717 which supported 1700mhz lte of Rogers, and yes it worked with wind and T-mobile network using 1700 mhz frequency only after flashing tmobile modem.

Lte will not work out of box, unless some developer gets you modem file which can make your N7105 to recognize 2600mhz as Bell LTE.

Yeah me too hate .....I was in long dilemma to buy N7105 , but when I found this then i just bought it outright from Rogers.
Also to let you know that even after flashing 2600mhz to work as lte radio, you will only get lte in 2600mhz lte available areas only, bcoz lte in NA fluctuates many frequencies from 700/1700/1900/2100/2600.
Good luck and enjoy your Note2.

I just bought a N7105 international version from Hong Kong and yes it work on Rogers here in Vancouver. Make sure you get a LTE compatible SIM card. My old SIM card did not compatible with LTE so I only got H+ or 3G. Now I changed and I am on 4G.
The reception is only 2 bars most of the time though. Sometime I got 4 bars. I tried data speed using Speedtest.net and still got at max 52Mbps DOWN and 34Mbps UP even I am at 2 bars so I guess it isn't too bad.

Hey rcyh same here i got my phone in HK..... I heard a lot people able to use 2600 Mhz on Rogers only ... Do you have any friend is using Bell and you can give it a try and see u are getting LTE there?
Woooooo comfirmed N7105 does work great with Rogers :fingers-crossed: I am getting 47Mbps down and 10Mbps up with 2 bar signal :angel:...... I think Bell just locked the LTE 2600Mhz band to public

you go the N7105 from where? Wind's SGH-T889V? Did you do anything (unlock/root/flash radio/other) to get LTE on Rogers?

[Q] wcdma 1700 band

the n7100 does not support 1700 band correct? i was looking around in the *#197328640# commands and noticed in debug>phone control>network control>band selection it gives you the option for wcdma 1700 is that an option that doesnt really work or could it be set to 1700 and possibly work on tmob also noticed 2100 as an option im just a noob when it comes to this so sure if it were an actual possibilty someone woud have said so by now
Unfortunately the N7100 does not support tmobile's 1700 Mhz AWS bands, the N7100 operates on the 1900 UMTS band in the U.S for tmobile for 3g. But there may be hope as there are some people in the AT&T Note 2 section that have found a way to enable AWS on the AT&T/ Rogers Note 2, and hopefully the same mod can be applied to the N7100 as they have the same chipset minus LTE support

[Q] i9082l what's the difference??

guys,
Whats is the differente between i9082 and i9082l?
I can flash android 4.2.2 in i9092l?
Thanks!
One is dual sim one is single sim. That's all I think. For custom roms based on stock Rom, I don't think they will work on i9082l due to different framework as the i9082 has dual sim function. Better ask the Dev before flashing any of the roms.

To be more technical:
Galaxy Grand 9082
3G Bands: HSDPA 900 / 1900 / 2100
Galaxy Grand 9082L
3G Bands: HSDPA 850 / 1900 / 2100
3G Bands are only available on the SIM Slot 1.
SIM Slot 2 on both devices run EDGE Only.

Wrong, SIM 2 can also can use 3G, just cannot use 3G for both SIM cards at the same time.

I guess then you are lucky, for I have 2 Data SIM cards, same operator, and when I switch to SIM 2 for data, only runs on EDGE. Then I searched the Technical Specifications of the device, and its reads exactly as what I posted. Hence, I copy pasted it from GSM Arena.
Perhaps some will, but atleast Mine.....doesnt.

Wrong again. You can't use 3G in SIM2 simply because SIM1 is the dominant SIM in 3G. To change that, just go to System Settings > More Settings > Mobile Network and in SIM1 tab check "Use only 2G Networks" box. A popup will show up "Current SIM card will be changed to 2G. Change other SIM card to 3G?" Choose OK and that's it.
i agree with henrispc013,
i can also use 3g/WCDMA with both sims, but not at the same time

No 4G connection

Hi,
I bought my N7105 from france, I moved to Dubai later on. Carrier supports 4G (du) but my phone mostly connects to H+, rarely 3G but never 4G.
I'm running a rooted official firmware 4.1.2, I searched on xda for same with issue it was there on Vodafone/AT&T in US and most solutions were a change in qualcomm's something!
In dubai they have GT N7100 but N7105 is not sold anywhere in middle east for some reason.
Please spare me the "buy a GT N7100" comments!
Would be great if have any suggestions.
Thanks.

Supporting 4G doesn't mean you'll GET 4G. They have to use the same frequency bands as supported by your device or it won't work.
According to 4g-map.info uae supports 1800 anf 2600 mhz so there is no reason why the n7105 wouldnt be comptible. What baseband do you have? Im running h3g nedma1 and I can see all three currently active 4g networks in the uk. So maybe try flashing that baseband check out the n7105 flashable modem collection in n7105 android development

Also check with your carrier. You might need a special APN for 4G access, you might need your IMEI added to an approved list.
There's much more to it than just the handsets physical capabilities.
Yes.. You have to check whether you device support the network frequency or not.
I am from Malaysia. Study in US currently. I am using my N7100. And T-mobile network.
T-Mobile doesnt support 1900mhz frequency (except san jose, san francisco and certain area). When i go out of these area, i only get 2G in my international version note 2. So, do do some research and get a carrier than has your device frequency. You can get the answer from Wiki.
Ask from your operator what frequency they are using for 4G. I think Note II supports 800, 900,1800 and 2600mhz for 4G. If ur operator uses other frequency which is not supported by Note2, then u wont get 4G on your device. In my operator, they use 1800mhz for 4G, so I can use 4G on my device.

If you look at my previous post you will see I have already told him what frequencies they use in uae. Plus the fact that the n7105 supports these frequencies

Sorry, but it's not going to work with this phone.
Orange Dominicana uses the 900 band frequency for 3g (WCDMA). On this phone that band is locked for being used with 2g (GSM). That's why you're getting Edge.
Unfortunately, the T-Mobile version of this phone also locked the 900 band for GSM. That means the NV data hack won't work for you either.
Sorry. Hope that explains it, and I hope they at least launch LTE service on a compatible band for you.
