Does anyone knows in depth diff between this versions? As usually samsung don't list the full specs of the US version at launch. Just a generic world wide FAQ which is innaccurate when we talk about localization. SM-G998U vs SMG998B vs SM-G998DS
Solved! Go to Solution.
To those of you mentioning how the S21 does not have MST, SD card slot, eSim, headphone Jack, Charger, headphones, LED light, pencil sharpener, heart rate and SPo2 sensor, please re-read the OP's question. They are asking for DIFFERENCES BETWEEN S21 models, not the difference between the S21 and other phones out there. The S21 of ANY model does not have any of these things (at least in the US).
@MisterySmile sadly, the TOS for this site prevents linking to other pages so anyone who links you to such pages will have their post deleted. Try googling S21 vs S21+, etc, and I am sure that you will find a page that actually answers your question.
The reason for that is simple: US model doesn't have the dual sim or eSIM. If I go with the LATAM or European model, what should I expect? As a fact. LATAM is advertised 5G. Nevertheless because of 5G bands enabled not being covered in US is not getting any 5G signal but only LTE and that's weak.
In contrast to Apple which enables all the bands on their phone, more or less, you'll have to dig in for information when it's about Samsung. Shame on them.
Here's some bottom line on the dual sim topic for the S-21 Ultra 5G model. I can use two SIMS in my phone perfectly. I'm on TMobile and I'm using two TMobile nano SIMs in the two-card tray. I bought my phone in Cambodia. The model is international, unlocked, will all frequencies active. Model SM-G998B/DS. It also has the Exynos 2100 processor with 256mb ram. Probably like you, I saw to many specifications sets with conflicting data regarding the Dual Sims. So today, I went to TMobile and I bought another line and added the 2nd SIM card. It works great.
I have the SM-G998DS which is the Intl Version. I am having a hard time getting decent data speeds on AT&T, only getting 3G speeds 3-5 Mbps at most.
My understanding is that this is a compatible GSM phone for AT&T, I live in a 5G area, how come I am only getting this speeds? AT&T says this phone is not compatible with their system going by the IMEI number.
What is the cause of this? Is there any recourse? Is there any solution?
