[Q] SHW-M440S & data roaming with European SIM card?

Hi,
I wonder if anyone else had the same issue. I can't seem to get my SHW-M440S do data roaming in another European country. I have the M44SKSJLI3 firmware installed. I have the correct APN settings for my SIM card (T-Mobile Hungary), and when I select 'data roaming on', it will warn me about the high charges, but then no data connection is established. (internet doesn't work, the 'data traffic' icon is not showing on the top bar)
I wonder what the issue is? did anyone else encounter the same problem?
best regards,
Akos

[Q] Disable SIM option missing

Recently, I used a Moto G and a Lenovo phone (both are dual SIM phones) and I found this Menu called Sim Managemnet in Settings. There is this feature by which you can disable the GSM radio of either of the SIMs. The entire communication of the particular SIM is disabled and not just Internet(as in the case of Sparkle V-by disabling Mobile Data).
I want to know whether everyone is devoid of the SIM Management feature or is it just me(as I haven't seen anyone else using Android One and Googling didn't help me). Is this some kind of hardware feature(my logic says not)? I've skimmed through android.developers site to find whether any function can be made use-of to disable GSM radio. But couldn't find one.
If anyone has found any solution for this problem then please respond.
I need to have this feature as I'm using my second SIM only for data and I rarely use data connection as for most of the time I will be connected to Internet over WiFi.

WiFi Calling only, deactivate mobile

Hi all,
I have a Samsung Galaxy S10e and was wondering if it is possible to use WiFi Calling but restrict the phone from logging into the mobile network.
Background: I used to live in Germany and am now living in India. I do have an India SIM Card in Slot 1, which I use as my main card. A SIM Card from Germany is in Slot 2. I am using WiFi Calling with it, when I need to place or receive call to/from Germany. To avoid accidently using the German SIM Card via the mobile network in India (which would be very expensive) and also to save a bit of battery power, I would like to restrict the SIM in Slot 2 from ever connecting to a mobile network, but still be able to automatically use WiFi Calling, whenever I am logged into a WiFi.
Is there any configuration to achieve this behaviour?
Thank you!
Fabian

Cellular data problem (SM-G998B/DS)

Hello,i'm having a internet connection problem with my Samsung s21 ultra whenever i'm using cellular data(not Wi-FI).It randomly lose connection and the only way to restore connection is to turn airplane mode on and off.First i thought it was problem with my carrier,but then i tested another carrier's sim card and the same problem occurred.After inspecting a little bit,ive noticed that my Service provider version is set to another country other where im currently living,and i was wondering can this be the reason why im having problems with connectivity and if it is ,is there any solution to that?
