[Discuss]How to Creat a QR-code to register new carrier profile - Samsung Gear S3

I had read some articles about eSim
and got the below Conclusion.
Only for docomo(Japan), but I think it maybe same to other countries providers!
1. eSim default has a limited profile.
It's initially stored in the eUICC when it is shipped. It is a limited-application communication profile used only for downloading and switching Operational Profiles for connect to the carrier.
The parameters are:
ICCID, MSISDN(sounds tel-bum), IMSI
2. The profile that be download to eSim, is generated on the server by staff of carrier, and if it's has been registered, it will be deleted.
So, if you want to register to GearS3 with another device's eSim number, you need to ask the carrier to generate profile again.

Many app support to create QR code.
I scan a Germany Carrier's QR code that use for activation,
Got the below URL.
Of course, it lack many parameters that contained by default profile in the eSim.

The URL OF ESIM server(docomo) is this.
From My asus d01j tablet, I plan to use this esim to register my SM-r765f
https://usmdp-001-prod-muc1-eb.venyonservices.com

Au, Another carrier's eSim, xml
It likes all of them use same site,
venyonservices.com

Many Thank you guys!
Plz refer me more info to creat QR-code to those carriers who don't supply QR for their Lte internet plan!

Another question!
Any guys know how to export an activated eSim profile?
Maybe We can make a dummy profile to download to gear3
A COPY eSim!

1.
Your SM-R765F is allready arrived?
2.
I can upload old/obsolete Firmware from SM-R765F for study...
Maybe you can find which files are eSIM related...
We have also SM-R765T and SM-R765A Firmware for study...
3.
German?
Du kannst nicht aus Versehen mich verstehen?
Best Regards

Dear brother ad free
Yes I receive the sm-r765f ,
buy from a Singapore girl who was luck for hit it in lot, and sell it on BBS.
It's amazing that I got a total brand new one and no registration for esim. Of course the ICCID is Singapore number dummy number(Singapore country code is 525, but this is 033!! ****The first digit of the mobile country code identifies the geographic region : 0 - Test networks***). See attached file.
So I think if can't replace it, maybe I can add necessary parameters to QR-code to overwrite.
Any way to export 765f's firmware? Tell me plz if know.
Thanks a lot.
I'm not Germany,
Even I like Germany's culture and products. ^^

It's much appreciated If you guys upload your own QR-code to study together!!!

Is it possible to change network name?

Hello.
First I want to say thank you to everybody, because I learned so much with this forum, and specially to all "ROM cookers".
Because I don't know very much about ROM cooking I want to ask if it is possible to change the network name that appears on the HTC Universal, because it is an old name, it shows as "UMTS Xfera" and the comercial name for that network is "Yoigo". I don't know if it so much work or if I can do it myself, but I don't know which file I should change.
And one more thing, I have been looking to create a .CAB file with my operator settings without luck because I only get some of the settings (I used a .CAB file for an other operator changing the settings) but no the full configuration, is there a "how to" to create the file?
Thank you in advance.
Regards.
yes, i just cant remember, google it.
Thank you Midget_1990, after a while I found how to modify it, you have to add an entry to the registry with the operator and network code (CCCOO) and the name you want to be shown on HKLM/Software/Microsoft/RIL/OperatorNames.
I have posted it here for anyone who needs it.
I will continue looking for a CAB file with GPRS & MMS settings for my operator.
Regards.
Ok so How you do it ?
Here you have the instructions (from Modaco Wiki):
-----------------------------
Customize operator's name
To show specified operator name set
HKLM\SOFTWARE\OEM\PhoneSetting\ONSDisplayRule=0 (DWORD decimal)
And then at
HKLM\SOFTWARE\Microsoft\RIL\Operator Names
add the code and the name to display. The value is 5 digits "CCCOO", where CCC is 3-digits country code, and OO is 2-digits operator's code. For example:
"25099"="BEE LINE"
For country and network code, go to wikipidea for [mobile country code|http://en.wikipedia.org/wiki/Listofmobilecountrycodes] and [network code|http://en.wikipedia.org/wiki/MobileNetworkCode]
To show operator name based on the SIM card used (eg for cases where dual SIM adapter are used), set
HKLM\SOFTWARE\OEM\PhoneSetting\ONSDisplayRule=1 (DWORD decimal)
For my dual-SIM adaptor, when I switch between SIMs, the phone with default settings showed always one and the same name, until I reboot the device. Then, it was not able to retrieve operator's name from one of the SIM cards I use. Probably it is an adaptor fault. But anyway, after I changed ONSDisplayRule to 0 and set more up-to-date names for operators that I use, I now always see the name of the operator of the chosen SIM.

WorldCallPlaceAndTime

Hi! Let me introduce a tiny app, available in English in the moment.
This program shows a small info window during incoming/outgoing call. It contents country, region, city (or mobile operator) and LOCAL TIME in that place (worldwide)!
See latest comments and screenshots on cyrket (I'm not allowed to insert links)
Detailed popup customization is supported
The phone base I collected and created (many errors there were fixed by hands) was only available in Russian, but today I released English base, made with help of Google Translate
I know, such translation is buggy (but still much better I expected). I hope you'll help me and other users to have a complete and accurate information about calls - just email me right from the program menu about any issues or comment here.
World time also changes (for example, Russia lost two time zones this March) and if you find any error - post here or email me
You don't need to download phone base. You may download its latest version from the app, but if you want to do it manually, unpack the zip to the sdcard's root
How accurate does it get? I don't get many international calls, but might be useful to know where a landline call from within the UK is coming from?
What happens with mobile calls from with the UK? I assume no detail at all then?
it covers both landline and mobile network all over the world, where it is possible to distinguish between numbers by area codes. just try =) there are more than 25000 records in the base

Hi. How do you set this up?
I have placed my Country Code (00351) and set GMT to +1 and when I call from my desk to my phone, it says it's a call from India ...
afaik, country code cant starts with zeros. Please, provide full number (you may hide last four digits) and right country for you I'll check and write settings here
Erm, I think techinally it either starts with two zeros, or a + but you're asking for a single number?
For example, UK is either 0044 or +44
wow. That is new for me. I know that with one leading zero start local calls. And you say two zeros replace + . hmmm. try left country code blank, that may help, I think. and if not, please, type whole number without four last digits
Not sure if this is already obvious but as there seems some uncertainty. AIUI the correct way to state an international number is to prefix it with +. To make a call, the plus sign is replaced with the two (or sometimes three or four) digit international access code which depends on the country one is placing the call from. For Europe this is 00, for the States, 011 etc.
I'm in Portugal, and my number is +35193233xxxx. I have tried leaving it blank, but by default leaves a 7... tried with 00351, with 351 and when calls are incoming still stays it's from India.
I'll wait for further clarification and if nothing happens I'll un-install it.
By the way, it doesn't let me use the +.
Thanks
okay, and what was the incoming number? what it was looking like on the call screen? country code preset replaces leading zero or eight digit. so it doesn't interfere number detection in you case I think
Sent from my T-Mobile G1 using the XDA mobile application powered by Tapatalk
The incoming number was looking like this: 91811xxx
It's a mobile number from Vodafone.
Just got a call from Germany, and it identified the Country and city allright. Seems that it doesn't work for calls inside Portugal only...
i see eight digits and no country info in this number. if there are seven digits program says local call and do not provide any information (because there is no trusted information) in eight or more digits it tries to detect country code. it replaces leading 8 or 0 with country code from the settings - for example local russian mobile calls may look like 8916xxxyyzz - we replace 8 with country code 7 and identify it with MTS - the program even say region or city based on x or xx or xxx in the example above. but in your situation I have no idea how to detect that the call is local and country code needs to be put before the number =( I've never heard that income mobile number may be in the format you wrote - it should start with plus sign and country code or 8 or zero (Ukraine, Moldova). I'm whirled

Any chance you can convert the database into something human-readable? I'll be glad to cross reference a bunch of Southern California area codes and prefixes so that you can get some more accurate data there.
Also, a program similar to yours got hit with a cease & desist a few months back by some patent trolls because they supposedly hold a patent on this very thing. You're in Russia though so I dunno if their reach extends to you. Just thought I'd give you an FYI.

and yeah... i've read that stuff and even contacted the author...
But, my program is better now, I think =) And I will hit 10000 downloads, I hope. That will be enough, I think, for my efforts and hand-made db =))

How do i uninstall de database, can't find it but i takes 3 mb of internal memory. Anyone has a suggestion!!

Just remove the DB app. There is no way to leave DB app and remove the DB, android OS restriction (can't modify signed apk on the device)
uninstallation
So when i uninstall WorldCallPlaceAndTime.apk than de database will be removed from my internal memeory?

What do manufacterers need to enable VOLTE on devices

Not having VOLTE is quiet an annoyance when you have been using it previously on other handsets.
what are the specifics regarding enabling volte by both carieer and manufacterer?
what information do they need to enable the service?
Manufacturers have to include the proper configuration for VoLTE/VoWifi in their devices, e.g. ISM, Gateways, etc.
VoLTE/VoWifi has to be configured a little different than the usual VoIP like e.g. SIP.
The GSM Association has a Device Settings Database (where telco's can provide the needed information for handset manufacturers/OEMs), into slides can be found here: www gsma com/futurenetworks/wp-content/uploads/2017/02/Device_Settings_Database.pdf (insert dots after www and before com)
Sadly, I guess the database is for registered vendors/telcos only..

is it the responsibility of the MNO to liaison with the phone manufacturer to provide the VOLTE / VOWIFI settings? (or atleast make available) and thus the manufacturer would update the settings via an update?
is it possible to get the settings manually via a device that already has volte?
what im trying to figure out is this
i have two phones. a huawei p20 and a oneplus 6
they both support the same bands so no issues there
volte works on my p20 and not my oneplus 6 - this is confusing.
my operator clearly favors huawei (as they sell it in store) so they provide the required information (or do they add configuration to the network) to get the volte working
my p20 was not purchased via my telco so there is no telco based firmware required to get it working.
if possible can we pull the information required from the phone / telco and make available for others to enable VOLTE?
From what I think I read: MNOs: At least the three big players here in Germany whitelisted tested handsets until about beginning of 2017 - then I guess they decided they tested their networks enough and now you can read on their pages that it's (solely?) the OEMs part of work to include the correct config tu support VoLTE/Wifi in their Firmware (e.g. Android release).
In principle, the MNOs should send the needed details how to configure for VoLTE/VoWifi to GSMAs database, where the phone manufacturers could access it to implement in their phones - so there's no contact between MNO and phone OEM necessary at all.
Of course, if a MNO sells a branded phone, they make sure that phone had that specific MNOs VoLTW/VoWifi settings embeded (and maybe ONLY for that MNO ) .
Maybe if we find a Qualcomm Snapdragon 845 based phone we'd be able to copy the configs for other providers. Seems the OP6 currently (5.1.8) has these configs included:

The files seem to have a digital signature, so it's unlikely that we'd be able to edit them, even if we would just know the correct parameters. Also, not everything is for VoLTE/Wifi.

It seems my network three uk is included, however VOLTE doesn't work for me.
See my last sentence in my last post
Those modem configs seem to include seperate config files for selecting the correct bands, etc.
I'd guess that mostly the directory entries with "volte" contain VoLTE settings

CellBroadcast and Emergency Warnings on Android - is it a mess?

Hey,
Germany is implementing EU-Alert (ETSI TS 102 900 [1]) at the moment and referring to the local News, it is a huge mess [2].
But let's start at the beginning.
CellBroadcast is a core component of each mobile network generation (2G,3G,4G,5G,...) and part of the 3GPP spec. CellBroadcast basically allows the network to send a simple SMS to all mobile phones connected to a specific base station. Thes SMS-CB are sent with a Message Identifier (aka Channel, aka Topic) which gives them a special purpose by convention. e.g. ID / Channel 50 is often used for area related information [3], while channel 207 might broadcast local weather information. Since not all Channels are standardized, there is also the option to broadcast an Index that lists all channels with a description. And since users probably don't want any message broadcasted, users have to subscribe to these channels.
Since decades now, CellBroadcast is also used for public Emergency Warnings. This means that, by definition of a country, a specific channel is used to broadcast Emergency Warnings. Long time ago, in many countries it looks like Channel 919 was used for this purpose. For this to work properly, mobile phones were instructed to subscribe to channel 919 by default and also use a special ringtone (even if muted) to alert such a message.
Later - over 12 years ago - additional channels from 4370-4399 were standardized in ETSI TS 123 041 [4] for public warning systems like CMAS, EU-Alert, KPAS. All using the same channels which is beneficial for global roaming.
Android of course supports these public warning systems specified in ETSI TS 123 041 [4] since at least Android 4.2.2 [5]. And nations that use these systems already, like CMAS in the US, report very high and reliable coverage.
However, referring to German news [2] and government, not many phones that are currently on the market will actually support EU-Alert in Germany, despite already supporting EU-Alert in Netherlands or CMAS in the US.
How is this possible when exactly the same SMS-CB is broadcasted, just in a different country?
Golem [2] says that Samsung and Google already confirmed that EU-Alert is currently not supported in Germany, but updates will be rolled out to recent devices.
This strongly suggests to me that OEMs like Samsung and Google actually added country specific filters/configurations for these public warning systems to their phones without deploying a reasonable fallback. Public warning systems based on ETSI TS 123 041 [4] thus may only work in countries that were known to use these systems when the phone was released.
Isn't this an obvious issue?
Google said, starting with Android 11+ it will be possible to update the CellBroadcastReceiver App via Google Play. So devices with Android 11+ will likely receive an update to support EU-Alert in Germany. For Android 10 and older, OEMs will have to supply updates.
What also confuses me is the fact that all Android Phones I own (Nexus 4 with Android 5, Nexus 5X with Android 8, Pixel 3a with Android 12) here in Germany do actually offer the setting for Emergency Warnings and they are already enabled by default. So I assume they would work? Did Google actually deploy a sane default configuration here already?
But if they did - why isn't it working on ALL Android 11+ Phones already? I'm pretty sure my Pixel 3a uses Googles CellBroadcastReceiver App which is provided through the Play Store. So all Android 11+ phones should already use the exact same App?! Or am I wrong here? So what is this update Google actually needs to provide?
And does this also mean that with Android 11+ OEMs are not allowed / cannot implement their own Emergency Warning CellBroadcastReceiver?
This topic is really confusing to me
Shouldn't it be really simple?
All phones, regardless of the OEM, should have a proper SMS-CB Application which allows you to subscribe to custom channels, view the index, and manage your SMS-CB Messages.
Phones should also be aware of special channels to apply special ringtones etc if needed, but they should have a sane fallbacks!
A phone that knows about NL-Alert and CMAS may call messages on Channel 4370 received in the Netherlands "NL-Alert". But when it receives the same message in Germany, it shouldn't just drop it! It should display it as warning and call it whatever it wants. And if it doesn't know about CMAS / EU-Alert, it should just receive it as regular SMS-CB.
Can't be that hard?
Interestingly enough, Samsung phones allow you to subscribe to custom channels. Google phones do not :/
Should there be a better / more enforced standard, so that a country that wants to implement CMAS/EU-Alert in the future doesn't have to rely on OEMs help?
And finally some technical Questions:
I found zero Apps for Android that would allow me to subscribe to custom CellBroadcast Channels on my Google Android phones. Is this even possible?
Also, is it possible to test these CellBroadcasts somehow? Is it possible to write an App that can inject SMS-CB into the system?
Sorry for the long post, but I think this an important Topic.
Let me know what you think
Do you have experience with these Emergency Warnings already?

Hey! I was just researching something about this. Thanks for your detailed post.
I am from Chile and, in my case, my operator had subscriptions to two channels: 919 and 920.
In order to see the Cell Broadcast menu in the Messages app, I had to override a CSC setting (I use a Samsung device), particularly "CarrierFeature_Message_DisableMenuCBMessage") because it seems some Chilean operators ordered Samsung to hide it.
Even then, the Google Cell Broadcast app would not let me modify settings other than test alerts.
In my country these emergency alerts are quite unreliable and are often sent by mistake or to the wrong place (i.e. sending a tsunami alert to an area more than 100 km away from the coast).

Can you explain how you disabled this CSC setting and on what samsung phone/os?
You can see Googles/Androids latest default configuration for Chile (MCC 730) here:
https://cs.android.com/android/plat...apps/CellBroadcastReceiver/res/values-mcc730/
The config.xml really has some restrictive features enabled :/
Thanks for your reply!
Please note that all the following information assumes you have rooted your device. It's impossible to override this configuration otherwise.
My device is a Galaxy Note20 Ultra (Exynos version, SM‑N985F) running Android 12, One UI 4.1.
As you might know, Samsung devices include several packages named “CSC”, which define settings according to a sales code matching with a region. For example, a device sold in Chile without a carrier uses the sales code CHO, while one sold by operator Movistar uses the sales code CHT.
In the Galaxy Note20 Ultra, the CSC packages are stored in /optics/config/carriers/single (older Samsung devices might use /omc/).
Once you find the sales code matching with your current configuration, you can grab two files: cscfeature.xml and customer_carrier_feature.json. Taking CHO again as an example, the files would be /optics/config/carriers/single/CHO/conf/system/cscfeature.xml and/optics/config/carriers/single/CHO/conf/system/customer_carrier_feature.json.
These files are encoded, but OmcTextDecoder can take care of that.
In the case of CHO, customer_carrier_feature.json has the value "CarrierFeature_Message_DisableMenuCBMessage":"TRUE", which hides the cell broadcast menu in the stock Messages application. Just replace “TRUE” with “FALSE”, save the file and push it to its location. The next time you reboot your system, it will be applied.
Regarding the link you sent, I think we could get around that configuration by decompiling the GoogleCellBroadcastApp.apk through Apktool, modifying the restrictive values, and then pushing the APK to the device, replacing the original version.
Thank you!
Let me know if you managed to patch your original CellBroadcastReceiver.apk!
I actually tried using Runtime Resource Overlays (RROs) which is described on the official docu about CellBroadcast in Android.
You can find the result here: https://github.com/xsrf/android-de-alert
However, I didn't quite get these RROs. It looked like in Oreo you can use RROs to overlay any resource of any app without any permissions or matching signatures, which is quite a surprise to me?!
On my phones with more recent OS, I get signature mismatch errors and also it looks like apps now have to define what resources can be overlayed ...

Question Canada Bell QR Code Activation for GW4 and GW5

Hello everyone,
I tried to activate my GW5 (LTE US Version) on Canadian Bell network by scanning the Bell's "generic" QR Code, and it was successful (getting the QR Code option by tapping 5 times on "Galaxy Wearable" in its "About" section of the app).
However, I just got a new number which I wanted to transfer the service and I had to re-do the activation, but this time it keeps saying "the code is not valid anymore, or it's been used" which is technically true because I already used that generic QR code once to activate before. The problem is that Canadian Bell Mobility doesn't generate unique QR Code vouchers (i.e. getting a new QR Code is not possible as they only have one general code which should be used for every scenario). Is there any way to bypass this and reuse the code via the Wearable app?! Anyone encountered a similar issue?
Any help is greatly appreciated!
