Hey everyone, I am thinking about buying a used ATT SGSII. From what I have read this phone will work fine on Tmobile (except 3g/4g). Will there be any problems with reception or text/mms messaging or does this phone use all the same Tmobile bands? Finally, will I have any issues unlocking this phone for Tmobile without an ATT SIM?
Thanks

Hello Friends,
I bought a SIM Free unlocked S6 Edge from Amazon UK, but it came locked and the box says it needs to be activated using a EU Sim for a first call for 5 minutes. today I tried it using it with an Indian SIM card but it says SIM not supported etc. As I am in India and want to use it here, want to know how to use it in India?
Since, I am a novice please share the steps involved to start using the phone in India. Thanks.

Yup! Tried with airtel, idea and vodafone
I never tried them, I'm using Jio 4g only.
i found a seller in chennai (india) who sells Snapdragon 845 editon of the galaxy s9 plus my main concerns are as follows
1. will it work without the 5 minute phone call required initially?
2. will it support volte (jio) in india without changing the firmware?
3. are indian bands supported especially for airtel and jio?
4. will warranty be covered in india?
5. will there be any issues that i should be concerned about?
thanks in advance

1. Yes
2. No. Jio VoLTE will NOT work.
3. Bands may be supported, but if there is 4G+ (LTE-A) in India, that may not work. And if you use a Jio SIM, only data will work, no voice calls due to lack of VoLTE.
4. No it won't.
5. Aside from the fact that VoLTE / LTE-A will not work on any network. Not really.
Regarding the band compatibility;
The S9+ USA model supports the following LTE bands (source: https://www.gsmarena.com/samsung_galaxy_s9+-8967.php)
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 14(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 29(700), 30(2300), 38(2600), 39(1900), 40(2300), 41(2500), 46, 66(1700/2100), 71(600) - USA
India LTE bands (source: https://m.gsmarena.com/network-bands.php3?sCountry=India)
LTE 850 (5), LTE 1800 (3), LTE 2100 (1), LTE 2300 (40), LTE 2500 (41)
So you should be fine regarding LTE compatibility (not sure about VoLTE and LTE-A).
Regarding warranty only the local Samsung customer service will be able to answer this 100% accurate (most likely no warranty).

As far as i know
1. No. You need to insert a country specific sim to activate/unlock the device.
2. No.
3. Yes. But in the first place you need to unlock the device which is not possible.
4. No.
5. You cannot root the device because bootloader is locked in snapdragon version and No carrier aggregation(LTE-A) support because the ca combinations are country/CSC specific.
Hi,
I have US bought tmobile unlocked s9+ device..JIO VOLTE doesnt work .. is it not fixable at all ?
Or is there a way out ?
Thanks
Bharat
M too facing same issue.
I researched a lot in last 2weeks on same but of no luck, found our that regarding volte the issue arising in many countries,
Small positive info got day before yesterday in s8forums Tgey said it was due to CSC in the firmware . And now a days all firmwares are multi CSC loaded, but since we used the phone in usa CSC from there was loaded, so I order load indian CNC we have to do the below.
if they just activated the phone after hard reset using indian sim they were able to use usa version with jio.. But I tried that too in vain no luck for us.
You may try above but.. you may lose data.. advise smart switch feature to sd card... if willing to do hard reset.
Please update if any luck
You may find ref link https://forum.xda-developers.com/galaxy-s8/help/how-to-install-indian-firmware-csc-inu-t3624953
I have not played with these before ..like installing firmware and all..mine is SM G965U model .. not sure the method mentioned would work ! 965F us international model ? And tweaks to this model only work not US models ?
I checked with Samsung too.. they said its country specific .. i dont know whether to try this method or leave as it is !!
Thanks
Even I got stuck over us CSC, and all samsung pay rewards which were only for us citizens..
Mine is G965U1, VOLTE doesnt work in india.
Since snapdragon not yet unlocked I had no options for VOLTE.. even If I do I may have to let go the Spay...
My advise don't Buy.. during deals we almost get similar rate e commerce sites in india...

Hey,
I am facing a similar issue. I got a unlocked USA S9 SM-G960U1.
I am using it in India but VOLTE does not work.
I am looking for a workaround. Any help will be appreciated
Thanks in advance
I have a S9+ snapdragon from T-mobile. Recently visited India. Jio volte does not work which was expected. But Airtel had bad reception and the internet would not work even intermittently when the 4g symbol was in display. However, in the same location, side by side, another airtel number on moto g worked flawlessly.
Even though the S9+ specifications shows all the network bands supported by Airtel, i did not expect to face the above problem. I am planning to sell the phone in the USA and buy a oneplus from India.
[SOLVED] use JIO SIM card on S9+ US Version in India
I purchased an S9+ ATT in December 2018, tried to use JIO SIM in India but no luck , then I wanted to get rid of ATT logo, which comes up every time I reboot my device. Did some research then and came across this forum https://forum.xda-developers.com/galaxy-s9/how-to/how-to-flash-u1-firmware-to-device-t3765200.
Was able successfully flash my device to US Unlocked version from ATT version 4 months ago , now I can see VoLTE toggle. Again tried to use JIO SIM , didn't work . Since then my device gets regular OTA updates :angel:.
AIRTEL network in my area sucks, Now 09/2019 again I tired to use JIO SIM and it works flawlessly.
HELLO I HAVE GALAXY S9+ U.S. VERSION. my jio sim is not allowing voice calls, and messages in this . Can anyone transform the trouble shoot method please
Like wise it is not working apple ( us version) 6 too
please

download the firmware for your carrier from www.sammobile.com/firmwares and flash it via Odin. If its the same android version, br sure to use the HOME_CSC file when flashing vs the normal CSC file to avoid an unnecessary factory reset. Flashing the HOME_CSC vs the CSC will allow you to keep all your stuff on your phone, CSC will factory reset it.

voLTE wont work unless you flash the CSC for your carrier on the device. voLTE is a carrier specific thing and requires the carrier specifc software to be installed which happens when the correct CSC file is on the device and the corresponding sim is entered

Hi everyone,

Thanks!
