Question S22u snapdragon US unclocked very slow 4g speed(10Mbps) in europe.

[noelbisha45]

Hi i got s22 ultra sd variant with model number SM-908U1 its unlocked.

I live in europe my phone carrier is Vodafone but my mobile data speed has problems.

4G only goes to 15Mbps with full bars i tried to reset the network settings still the same results.



I can think of a way of fixing it by changing software region to hong kong beacuse it comes with sd but i will wait till june cause i dont have much time now.Maybe samsung will fix it id they dont i will try this method if anyone else finds a fix or tries this method feel free to share the results.

EDIT:i checked vodafone bands and it uses B3 and B7 which are supported checked in samsung band selection app.
I think it might be a software bug

That's why I stay on Exynos. The SD model doesn't support all the bands we have in Europe.

 

[Abaddon]

Only if we could unlock all the disabled/hidden bands

Im pretty sure it does support many of them

Did you select those bands from the all to see if there's a difference in speeds

Yup selected b3 b7 first the speed was the same and then I tried with other bands some worked some not but still the speed was the same.

I have the same experience. bought US unlocked U1 but used it outside europe. now, wont even detect 5G. was hoping could find a way to flash it into global firmware with local csc supported.

Your firmware should be for sd otherwise the phone wont boot.There are a lot of countries with sd you can try to flash them.

why do u need more than 15mbps speeds? youtube streams take 2-3 mbps only

use wifi for more speeds

Same carrier, Vodafone, same problems in Italy but I have a fix.

I got an ATT sim, if you flash the U firmware with the sim in the phone you'll get the ATT branded software which, for some reasons, supports even 5G (tested over 600mbps).The problem is that the U1 firmware is designed to be "optimised" for the carrier of your Sim. Unlikely since we are not using an American carrier, the system doesn't know what bands enable, so it sets all to some ****ty default values.

You can buy a pre-paid ATT sim here in Italy for 30-40 euros.

I hope this helps!

Thanks anyway but we dont have ATT sims here in Albania.

I was lucky enough that the same persone who sold me my S22U had an ATT sim so he just sent it to me for free. Still, prepaid sim can be bought via various sites, Amazon ecc. Maybe you can search if one those ships to Albania

I think it may be a sim card issue right now it just went to 40Mbps

I also get sometimes 60mbps, the problems is that here in Italy we have 5G which doesn't work in U1 firmware. Also, ia had an itlain s22 Ultra for comparison: same sim, same place, the Italian S22U did 170mbps Download while the US one only 10mbps.

After i flashed the ATT firmware they both got the same speeds (1-5mbps difference)

It depends what bands vodafone uses search the bands online or ask them and try to use samsung band selector to choose those bands it may work

You need to use a latched version of odin that lets you flash an U firmware over U1 and viceversa. That versión can be downloaded here in the attachments.
