5G or dual 4G - Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans

Anybody encounter this? When I try to select 5G as preferred network. It says I have to disable dual 4G which effectively made the phone single sim... I wonder if other phones are like this as well. This could be due to 5G is still NSA now which means phone has to connect to both 4G and 5G at the same time.

I think this phone is not advertised as dual 5G, check Redmi 10x pro 5g, it says first dual 5G phone.

I got my Poco today and was surprised at this. I assumed I could have my data SIM set to 5g if available and my other to be still available...

This is stupid, and obviously a software limitation since other phones with the same cpu and modem can activate both sims simultaneously with 5g on one of them. Poco should fix this issue with a software update.

I'm not expecting it to be dual 5G.i just want the other sim to work when I activate 5G on the other one. At least 4G on the other sim will be good.

That is not true, the Snapdragon 865 can use 2x 4G or 1x 5G, only the new MediaTek can run both with 5G (800, 820 and 1000).

It is true and was working on my S20 ultra and also on mate 30 5g, MediaTek is not the only chipset that does it

On the user manual it says that the Dual SIM with a sim in 5G will be activated with future updates. Do you know anything about the activation date?

Nobody knows that... For now only few Xiaomi devices are capable to work on dual 5G standby (Mi 10 Lite 5G and Redmi 10x 5G as I know).
But that was the same problem in the beginning with dual 4G... On most devices this has been enabled with update...

Jio Sim not working with Galaxy S6

intimateangel said:
Yup its working flawless with iPhone 6s+, they had a full fledged testing to get it Apple certified as well.
But don't confuse it with "Reliance" this is a different company. Reliance Communications is a company in loss with sad networks and cheap rates!
Jio is a different company. They also have apps like Jiochat, and other beta apps like Jio Play.

Hi,
I am trying to use Jio 4G Sim with Galaxy S6 but not working
The sim only works with LYF handset which I have to buy to experience Jio 4G

Something else might be wrong.
I have tried Jio 4G in many handsets like
Galaxy A8
Motorola G3
Xiaomi Redmi Note
Oneplus 2
Oneplus X
So yours is an isolated issue.
You already came up to the conclusion that it only works with LYF handsets !

Even with the new jio free offers sim does not work with s6 verizon. I think it is due to the fact that verizon 4g lte band uses a different band (probably 13 or 18 )and jio uses band 40. Verizon locks the other lte bands.That's why jio might not be working on s6

Poco F2 Pro or K30 Pro/Zoom for Vodafone UK?

hi guys & gals,
currently using poco f1 and tempted to upgrade but was wondering from any vodafone uk users, which would you recommend? My sim is 5G enabled but currently using 4G. I know Band 20 (800) is missing from the K30 pro but have any users had any issues with 4G reception? I found a price of £370 for the K30 pro (8/128) or the pro zoom at £422. tbh i dont really use the camera much so missing OIS is not that important.
I would check what 5g band Vodafone uses. Specially if you want to use 5g. You may have problems with 4g cause Vodafone uses bands are missing from the k30 pro.
I think if you would have a different provider, probably wouldn't even notice the missing bands but Vodafone is the most affected on this.
On the poco however only supports 2 5g bands. I would do my research before purchasing if I was you. GL

Get the Poco f2 pro instead of k30 pro, it has band 20
It's basically the same phone, except network bands. Got mine from AliExpress for 420 but now it's about 380£. It works fine with EE
According to this site https://kenstechtips.com/index.php/uk-network-frequency-bands Vodafone uses N78 which the Poco f2 pro has.

K30 Pro Zoom is better with OIS and same price than POCO F2. I dont have problems using it without band 20 in Spain, I have very good 4g signal and I use same bands than vodafone UK (B1, B3, B7). Also If you have 5g enabled I would prefer K30 Pro because it have more 5g bands than POCO F2 and, if im not wrong, next year companies will add band 1 (n1) support to 5g and only chinese K30 Pro have it:

I have Poco F2 Pro on Vodafone (Voxi) in the UK, no problem with 4G - same reception as my pixel 3a. I don't have a 5G plan though so can't comment on that.
so been playing around with network signal info for the past few days, even though 4g band 1 was being used (80%), it would still fallback to band 20. as i also travel to thailand quite regularly, 5g band n41 would have been useful so looks like the f2 seems to be the one. the zoom would have been nicer tho
took the plunge and got the poco 8gb for £325.99, just waiting on dhl

Z Fold 2 not showing 5G

So I had a Note 20 Ultra which always had 5G everywhere I go but today I changed to the Z Fold2 5G and its not 5G at all. I get LTE+...
Any idea whats happening?
Are you using unlocked version? If so, I have same issue. Never seen 5G logo on AT&T
Sent from my SM-F916U1 using Tapatalk
I have the same as you... SM-F916U1
You never had "5G" on your previous AT&T branded phones. You had 5Ge which is AT&T marketing speak for LTE+. Google it. AT&T's premature declaration of 5G caused quite an uproar. AT&T branded phones display the 5G icon when on LTE+ because it's baked in to the s/w. Unlocked phones see LTE+ for what it is. If you're in a real 5G market the correct icon will display. I left AT&T for T-Mobile and my unlocked phone displays the 5G icon because my market is 5G.

Your screen shot shows you connected to Wi-Fi. The 5G (or LTE) symbol will pop up occasionally when I'm on Wi-Fi but the majority of the time my phone looks like yours. T-Mobile has low-band (~40MB - 50MB) 5G by my house and mid-band (+100MB) near my office. For some reason the mid-band towers near my office stopped working and I only get LTE+ there now. With the Sprint migration T-Mobile is doing a hella lot of network (re)configuration so maybe that's why you're on LTE.
Here's my phone from home so I know it's picking up 5G when it's there to pick up.

I am on AT&T unlocked, it shows 5G icon in status bar with no problem. Upgrade your sim card and pay for 5G data plan.
Would I have any problem using the unlocked version with Verizon and their sudo-5G? My Note 10+ won't get 5G anywhere but my wife's S20UW does due to the UW radio. Honestly it isn't any faster than my 4G yet, but I expect it will eventually.
Also, is there any reason to choose a carrier specific model vs the unlocked?

Sorry that the answer does not suit you but it is like that. Access to bands is blocked by Xiaomi. If it were possible, we would all have bought the K30 pro which is cheaper.
https://cacombos.com/device/M2004J11G Good also check Poco F2 support also EN_DC and CA combinations used on your country. I don't have K30 Pro combinations on my site but global model often better.
Combinations are defined to modem firmware and compiled. There is no way change combinations without recompile modem firmware.

The missing bands are not due to the software but to the hardware (modem).
The Xiaomi eu roms remove 5GHz(wifi) region restrictions not 5G.
For phones for the global market with their equivalent in China, if you flash the global rom on the Chinese version the missing bands will still be missing and if you do the opposite you will have the same bands as on the global version.

Update, Well I got excited today for about 5 minutes. I tried a PureTalk sim in my 12S and bang it showed a 5G connection. PureTalk in the USA is a MVNO for ATT. ATT shows 3 5G bands that are supported on the 12S.
Unfortunately I ran a few speed tests and was only getting about 50-60mbs download speed ugh... Worse speeds then I was getting with T-Mobile LTE...

PureTalk use N5 (850MHz), N77 (3.7GHz),N260 (39GHz) but you were surely on a N5 which emit far enough unlike the others.

So being on N5 does that explain the slower speeds ? Is there anyway to tell which band I am connected to?

The N5 is far-reaching but does not offer higher throughput than 4g or 4g+.
You will find on the play store (I don't remember the name).
In France the B700 5g +/- 60mbs, 4g +/- 120mbs ,5G 3500 +/- 300mbs****
****Provided you are less than 1km from the antenna.
Note that MVNO often provide the least.
5G 3,5 GHz

So for another test I took out the Puretalk sim and put it in my iPhone 13Pro, and what do you know triple the DL speed on 5G then on the 12s. So I would assume that the iPhone supports more 5g frequencies then the 12s?

Thanks that's what I thought. Oh well so much for "true" 5g support in the USA... Kind of bummed about this. I finally unlocked my 12s installed the .eu rom which at least for me transforms the phone into something quite usable now. i.e Android Auto, much better integration with google services... Basically just works now..

only LTE in USA on google fi (which uses t-mobile) but download speed seems twice as fast as i was getting on the mi 11 ultra, i usually get about 600/50 on devices with 5G in my area. I really don't have a need for that much speed on my phones.
