With AT&T recently announcing that from Feb 2022, only phones that support VOLTE will be able to access their network. Is there anyway to get a TGY 9810 S20 to have VOLTE? I use dual SIM and the 2md sim is Google FI. I have no problem for VOLTE on that network. It's the AT&T sim that uses UMTS instead of LTE for voice network during calls.
Anyway to change this?

Does anyone know how to use jio SIM on tab 3 7 or how to active engineering mode
Reliance Jio is a CDMA/LTE operator. They do not have GSM or UMTS towers. Only CDMA and LTE devices can work on their network.
You will need either a CDMA capable Galaxy Tab 3 variant (SM-T217S, specifically designed for Sprint in United States and will generally be SIM locked), or an LTE-capable variant supporting India's LTE bands.
Jio does not offer GSM or UMTS services. If your Galaxy Tab 3 variant is a 3G/GSM variant, it can never work with Jio.
As an addendum, you won't be able to use SMS with Jio if you use a compatible LTE device that isn't also CDMA. GSM-based LTE devices can only send SMS over LTE when connected to LTE operators that upgraded from GSM and UMTS, or if both the network and device support VoLTE.
I have just bough Samsung A50. I have inserted a Vodafone SIM in slot 1 and using for a few days now. I do not Get VOLTE on either sim Slots. But if i insert the same sim in my Oneplus 5T , I get Volte network for Vodafone.

It is a Samsung Variant based issue.
I have the SM-A505G variant and US carriers even though the phone is provisioned for VoLTE will only let calls go through on UMTS/HSPDA/HSPUA 3.5G . Only the U variant will work on VoLTE. I believe the G variant firmware will only be compatible with Latin America carriers even though they have US LTE bands. Weird.
I also have the SM-A505G variant and am using it successfully in the USA with VOLTE on the T-Mobile Network.

The U variant is officially distributed in the US so it should work with VOLTE in US/N.A.. Samsung or some carriers probably block other variants from accessing VOLTE through a whitelist. Probably for product segmentation.
Hi,
Does anyone have the 0 or F/DS variant in Canada and do any of the following features work for you? If they do or don't please also post your carrier (I'm on Telus).
- WiFi Calling
- LTE-A
- VoLTE
- e-SIM
Looking at getting the Hong Kong variant since e-SIM isn't even a working function in Canada or the USA for that matter when the iPhone and other phones get it. Every year I push myself closer and closer to just getting an iPhone. Boot loader completely locked down, check. Can't root, check. VoLTE doesn't work unless it's a carrier phone, check. No e-SIM, check. Like what's the point of an Android anymore? All the above features work on an iPhone no matter what carrier (or country for that matter) you bought it from. Samsung is a mush of CSC files, hardware variants, LTE bands...
Thanks,

No such thing as a perfect device, likely never will be. Best option is to list feature priorities then decide. i have the Hong Kong variant on T-mobile USA. Dual SIM which eliminates the need for an eSIM, bootloader is unlocked, can root the device. WiFi Calling and VoLTE function but no Carrier Aggeration (LTE-A). I wouldn't consider the F/DS variant, it has the Exynos SoC. Not an iPhone fan either, not impressed with their devices or ecosystem.
Thanks for the reply, its nice to see at least VoLTE and WiFi calling work (at least on T-Mobile in the USA). Anyone here on Telus? LTE-A isn't a priority considering a single band is typically fast enough for me these days, if I'm on a lower band it's for a reason (like distance). Does your dual SIM phone still support e-SIM? It's nice just to scan a plan and get going verses hunting the airport / local stores for a SIM.
Priority for me goes:
1) WiFi Calling
2) VoLTE
3) e-SIM
4) LTE-A

eSIM isn't available unless you aquire an International Variant with the Exynos SoC. I'm not aware of any Dual SIM devices which support eSIM. IMHO you have to really want the eSIM to sacrifice a device with a vastly inferior Exynos SoC.

No no, dual SIM would be best in that case. Anyone in Canada can comment on the above?
Does Wifi-Calling work on both SIMs or SIM/eSIM on the S2, if they are from a different region?
Both my providers allow Wifi-Calling abroad.
Can anybody please confirm?
I have a Telus S20+ only support VoLTE, no WIFI-Calling. The reason I get this phone because of esim such a big disappointment.
I have Hongkong variant s20 5G (sm-g9810) using in Sri Lanka.
The phone supports physical dual SIM , dual 5G, VoLTE , VolWIFI.
Only disappointment with Hongkong variant is the lack of e-sim support and Call recording feature.
I have a bootloader unlocked, rooted Galaxy S20 Ultra SM-G9880 (Hong Kong version) that I am using on T-Mobile. However, I had some doubts about how it interacts with the various bands.
The phone does not support some of T-Mobile's LTE bands, and it does not seem to support any of their current 5G bands. Is there any way to change this with CSC changes or any other trickery?
Would AT&T be better for any of this?
When I use the Samsung band selector app, I see that NR B41 is supported. This is the Sprint spectrum that T-Mobile is repurposing, correct? Does that mean additional 5G and LTE coverage once the rollout is complete?
Another user was having problems enabling carrier aggregation. Is there a way of doing this?

You can't change to a US CSC on your device. Some users are reporting 5G works only on SIM2. Carrier Aggregation isn't compatible in the US with the SM-G9880. I have the Hong Kong variant on T-mobile and 4G LTE works fine.

Would you happen to know if our imei works with 5g on t mobile? I just switched last month from att. On att, you would have to call and give an att imei in order for 5g to work and I'm wondering if t mobile is the same way or if it works out of the box with our imei.
Also, I have an SD card and seems like I cannot have a Sim on slot 2 and an SD at the same time, do you happen to know if an esim will get 5g?

That's a question for T-mobile. It's not a question of your IMEI, it's whether or not your device's available 4G and 5G bands are compatible with T-mobile. I don't know what model you have but if it's a US model eSim isn't available on S20 devices. Only Exynos devices have eSim capabilities.

I have the same model that's been on topic... The SM-G9880...
SM-G9880 isn't eSim enabled, only Exynos variants offer this. 5G may work, take it to your local T-mobile store and see if they can set it up. Often times information coming from a CSR over the phone isn't reliable. If it worked with AT&T on SIM 1 T-mobile it MAY work as well however many users have stated it only works on SIM 2. Even though T-mobile's 5G network has a larger coverage area they can't match the speed of AT&T's mmWave network.

I know that some people were trying to enable eSIM on rooted Snapdragon S20 Ultra devices. Did anything ever happen with that?

If you root the device I suppose it's possible to override an eSim block on the SM-G9880 but I'm not aware of anyone achieving it. The only Snapdragon variant which offers eSim at this time is the Galaxy Fold. I don't understand what the value of eSim is on a Dual SIM device. Even if you travel to a different country it's a simple choice, keep the SD Card in or use both SIM's and rely on internal memory for storage.
Did anyone try using BRI CSC to see if CA works in the USA?
i have a 835 singapore variant does anyone know of a way to get VoLTE i lost calling with AT&T this month since it only calls over 3G
