Hello,
I normally live in Germany, and use a pre-paid Vodafone SIM in my XDA there. I am in France for a while, and because my SIM is pre-paid there is no global roaming. So I bought a local pre-paid SIM, but it doesn't work in my XDA, can't find a network. But the new SIM works fine in my friend's Nokia... And my XDA is not locked, it was locked to O2 when I bought it but I used the tool from this site to unlock it...
Does anyone have any idea why it can't find a network, even though the SIM works in a Nokia? I thought maybe the band switching tool could be useful, but I think Germany and France use the same band so that won't make any difference... Any other ideas?
Thanks,
Suzie
Hi Friends
please help me
I'm from India and Im planning to buy RN3 but I want know that this mobile support CDMA sim?
If so how about the battery life in CDMA network?
Thanks in advance
Hi,
Today I received my New RN3 32GB Gold (snapdragon)
and I can confirm that Reliance CDMA is working in Both SIM slots with CDMA2000 EvDo
but have to add the APN settings manually
i also use CDMA MTS with Rn3
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

Hello, I would like to know if people have 4g with t mobile or at the with the mate 10.
I've used this phone in France and I didn't have any 4g issues
But in USA I only have 3g?
I've rebrand from alp l00 to l29
Thanks
Carriers in us is problem... I am now in Poland and 4g working perfectly. Last week same firmware in Chicago only 3g
Yes, i gave to my brother the phone, he lives in New york. (I've bought a pocophone)
He has one AT&T sim and one french sim
AT&T sim's got 4G
French (SFR) sim's one not
It's seems like roaming issues ?
i have mate 10 alp-l29 rebranded to c636 and LTE works great on Tmobile. LTE+ works too. you can get voLTE working as well if you want, though it doesn't work very well
Are you in roaming ?
VoLTE ? He doesn't have the option.... He is on .141 without root
When i own it, i've root the phone to get VoLTE in france but without root, no voLTE option...
Hi
received my Mate 20 Pro 256GB Dual Sim from Trading Shenzen.
So far great device, but missing Wifi calling.
There is no option to activate in settings.
My phone details:
Modell: LYA-AL10
Build Nummer: 9.0.0.161(C00E155R1P20) GPU Turbo
So maybe i had to switch to another firmware.
Wondering in hiSuite: Got information there that i have the newest Developer Version?
So can some assist / help to get wifi calling?
Or is it possible to flash LYA-L29 to this device?
thanks
I've never had WiFi Calling on any Huawei phones running EMUI or Xiaomi phones running MIUI but I am in the United States. MIUI doesn't have any option for WiFi Calling but maybe EMUI does depending on region.
You have the Chinese hardware version so I don't think you will be able to flash any international firmware on it but your best bet to find out would be to contact FunkyHuawei.
In case you haven't heard of them FunkyHuawei is a paid service many Huawei owners use to flash firmware updates, rebrand their phones to different regions, obtain bootloader unlock codes, etc.
I'm not personally endorsing the service (although I have used it) but the person who runs FunkyHuawei would probably be in the best position to answer your question since he reverse engineers the software on Huawei phones and owns Chinese and international variants of the Mate 20 Pro.
Can’t go from China to Non-China
Hi I have the same problems (want to move from Chinese LYA-AL10 to a non-Chinese version such as LYA-L29 for instance).
I ask FunkyHuawei and they replied to me «*cannot go from China to Non-China*»
If someone still manage to do it, please let us know !
Cheers
I have the lya variant I picked up in Malaysia on vacation. WiFi calling does not work with my T-Mobile (US) SIM card. However it does work when I had a Malaysian Sim card in it. The option would show up in the sim settings. From what I read WiFi calling does not work outside of Asia.

It does work outside APAC...I'm in Canada and while my provider (Videotron) has NOT enabled VoLTE and VoWIFI for this phone, I borrowed a Rogers (other CDN provider) SIM and VoLTE and VoWIFI were available. The provider has to enable these features for a particular phone.
