[Q] Galaxy s3 H+ and video call issues

Hi, I've recently bought a Galaxy S3, Module: SHV-E210L from a website it seems to be original i check with some apps on the Appstore.
But for some reason it can only connect to 3G while in my galaxy s2 i could connect to H+.
I tried to upgrade the firmware to 4.3 but it didnt help. Also I cant make video calls i got this weird icon on the status bar that i guess i related and when i try to make a video call i get: Videos Calls not supported in international roaming area.(I attached a file with the icon)
I tried to deselect roaming(althogh my carrier said to keep it on) it didnt help.
Thank you very very much for the support
Your in the i9300 / 305 forum you need help from the e210l community.
The S3 you bought is a Korean model and so its optimised for Korean network bands. By using it in your own country the phone thinks its roaming, hence why a.) You have two clocks on your lockscreen and b.) You can only connect to 3G and not H+ or 4G LTE (that variant is 4G enabled).
Its probably also why you can't make video calls.
Thank you for your replies ill go to the other forum, but can you please tell me if there is anything i can do about it? like a installing some other rom or something?

converting s6 edge G925L to G925F

Hi,
I currently have the G925L version of the S6 edge, (with LTE-A), and I really dont like that there are built in korean system apps, as well as limited development. there are also some options missing like selecting mobile connectivity (it is just set to LTE, no option for 3g or 2g) Is there any way that i can flash the G925F version over it without having problems with the mobile connectivity? because maybe the mobile chip is different.
Any help would be greatly appreciated.

[Q] WIFI Calling for CarHDROM v5.3?

I am running CarHDROM V5.3 on my Galaxy S6 Edge running 5.1.1(OF6). I love the ROM, just wondering if there is a patch for the ROM so it has the wifi calling feature? Only reason I ask is cause I don't get good cell reception at home and the WIFI calling is needed for texting and phone calls.
Thanks for all the work you do!

Fido S6 / S6 Edge Calls go to voicemail when on wifi after 5.1.1 update

I have an S6 Edge that just got the OTA yesterday for 5.1.1 on Fido. My girlfriend also has the S6 and updated to 5.1.1. We are both having issues where calls are going directly to voicemail. I've narrowed it down to this only happening when we are on wifi. I tried calling fido and they weren't much help. Anyone else experiencing this ?
I have the same issue. For now to fix it you can go to settings.mobile networks. Network mode. And select GSM/HSPA
Of course this means you can't use LTE. So this is not a real solution.
Same issue on Rogers. Its sporadic though sometimes calls do come through.
Same Issue with the Samsung Galaxy S6 with Fido. I had that problem the first time they rolled out the 5.1.1 update. I can't receive text messages or calls when it switches between 4G and LTE network I noticed at poor locations where its not a steady LTE connection, But i can still call out and text out. I brought it to Samsung repair shop and they downgraded the version back to 5.0.2 and they said it was a bug. Updated it again on Oct 10 and it had the same issue, i'm guessing Samsung didn't fix the problem the first time. The other solution like mmilani said is to go to settings -> mobile networks -> Network mode and select GSM/HSPA. I guess we will have to ride it out until Marshmallow get released.

Anyone have WiFi Calling enabled and working on T-Mobile US?

I really need WiFi Calling in order to reasonably use this phone for calls from my house due to a poor Network signal. There is no Wifi Calling option in Calls -> Settings or in Settings -> Network & internet -> Mobile network anywhere. Also when I do *#*#4636#*#* and go into Phone information Wifi Calling Provisioned option is grayed out.
Nope. Last time I saw wifi calling available was on the XZP. Wasn't an option for the XZ3, and still not an option for the Xperia 1. Try giving tmobile a call or maybe sony support and ask if they can add wifi calling support.

Option is here for me. Can you not flash a non branded firmware?

Which frimeware is that ? Is that US unbranded
Nope, no wifi calling for me. I originally had the J9110 model (international dual sim, hong kong) but i recently flashed it with the US firmware. No dice, unfortunately. But since changing to the US firmware, I now get VoLTE and group message in Android Messages. It's a start.
Ya VoLTE is working fine and appears as provisioned in the hidden menu. So it seems like I will have to do something similar to what I did on the XZ Premium in order to get WiFi Calling...but I will wait until there is a DRM backup process.

I see the same thing as you. How did you do it on the xz premium?
I had to root it and flash a zip that someone made for it, it might be possible to use the same zip but I'm not going to root mine until there is a DRM backup method. I barely every talk on the phone without LTE service so it's more so just really annoying not having WiFi Calling. I think a bunch of people were using the same zip for the 2017/2018 xperia phones to get it working.
I have XZ premium and XZ1 and wifi calling option is displayed when I use the Jio sim but not displayed when using Airtel sim (using Airtel broadband), so our phones do have wifi calling facility but working only with Jio sim, although Sony is not shown in the compatible phones list. I am in India.
That also stresses me out on My Xperia 5. Don't know If You talked about My Zips for VoLTE and the other Features but i didn't get it to work actually on Android 10. Possible that i just don't have the right Firmware atm (Customized EU / My Devices Firmware isn't Out yet), so i'm using Custom UK Firmware but that should also work... I'm a bit confused so i switched to GSIs which Made it even worse... Looks like we should start making Custom Vendors for our Xperias since the Methods changed over Android 7-8-9-10
Can you flash the dual sim model to work with a single sim firmware and does Wi-fi Calling Work later?
yes, that's what i did with my xz3. volte works with tmobile, but not att.
