USA model vs. Int'l model

Hello everyone,
I am on T-Mobile in the USA. I have an LG G4 currently which I am looking to replace, probably with a 7x. I know the Int'l version has 4GB of RAM, while the USA model only has 3GB, but the USA model would have all the correct bands for T-Mobile USA. Does anyone have any usage experience yet with the USA model and could tell me if the RAM difference is noticable or if the extra GB RAM is worth not having true 4g LTE bands here in California? My previous LG G4 was an Int'l version and could get HSPA, but not the LTE 4g. I can get LTE 4g on this LG now but the phone itself is so slow I'm not sure I am able to appreciate the speed that is available to me. Thanks for any advice.

It's pretty cheap so, if you're going to use it for only scrolling through social media or web browsing then this phone is fine. FHD+ Screen with minimal lag for 199, it's pretty hard to beat.

I just got the phone yesterday and I live in California as well and have T-mobile.It works really welly.I don't think the ram would be much of a difference,great mid-range budget phone in my honest opinion

Does the 7x support VOLTE and wifi calling work on Tmobile. Thanks

Some reported that volte work on T-Mobile

The international version doesn't have cellular radios that support T Mobile or AT&T 4G FDD bands. If you buy an the international version, you'll be limited to slower 3G speeds when using cellular data and possibly less network connectivity. There's no formal support for Volte.
Before buying an unlocked phone to use on a US GSM network, you need to research the 4G FDD radio bands used by the carrier and make sure the phone you want supports those FDD radio bands. (Verizon users, even when Verizon abandons CDMA in 2019, you won't be able to go out and buy any phone with the correct FDD bands and that supports VoLTE to use on their network. Verizon has made it clear that it will only provision phones that it has tested and certified.) Here's a link with US and Canadian carrier bands. https://www.signalbooster.com/pages/...-in-usa-canada

Galaxy S9 LTE support

Hey guys, currently live in the UK and am looking to purchase the S9, the model that catches my eye is the SM-G965FD*(Asian Model) as I've read the dual sum variant supports dual sim LTE/4G (Both sims can connect to 4G) and hopefully this is simultaneous like the Mate 10 Pro is.
Now I have a question, I know the phone will work on 4G here as I've checked the bands, but I'll be visiting Argentina soon for a month or so and I am wondering if it works there. As I've read that North and South America uses a type of LTE called AWS, I don't believe this is used in the UK or Europe.
Just wondering so I don't arrive there with a local SIM and be dissapointed. Also can someone confirm this variant does support Dual SIM 4G/LTE as the global variant is 4G/LTE in SIM slot 1 and only 3G-2G in SIM 2.
Cheers!

S20 (0 - Hong Kong variant or F/DS - Dual SIM international) in Canada

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.

A505F Mobile Network in the US

Hello,
Just wondering if anyone has experience getting LTE/4G data working on their A505F in the United States?
I unfortunately bought the wrong model without being aware of different variants for regions on ebay, and while everything works great (mms, voice calling), I can't get my LTE/4G data to work probably due to the lack of LTE bands that my carrier requires. Just wondering if there has been any workaround this....or any positive experiences, if that's even possible.

Questions about G9880 and T-Mobile

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?
