Update 5G bands - Samsung Galaxy Note 20 Ultra Questions & Answers

Last week I broke the display on my N986B DS 5g, I found a new one on the bay and last night I did the "surgery". After I opened it I discover that 2 5g antenna was missing and they are probably what i need to get 5g here in the us!
I found the spare parts online a d my question is: If I install those 5g antennas, the phone will be able to receive those frequencies or the 986B hardware is not capable? Could be a question of software?
Thanks for anyone who wants to reply.

Possible to convert 5G variant to 4G variant??

So after searching around the internet and forums and discovering the 5G model is basically not receiving the same attention as the 4G I was wondering if any developers could answer me this, is it possible to convert the phone somehow? Of course I aren't expecting to use 5G if it is possible ( it's the only model EE offer) so had no choice but after reading that updates are none existent and there is no custom ROM support nor are we eligible for android beta programs ??*
In short: No.
I've seen it smart 5g but modem is the question best to ask a Dev who builds kernel 5g has a ways to go by next OnePlus release trade up is best way
Not really, no. AFAIK (I've done zero research on this so I can very possibly be wrong), the SOC in the 4G version is different from the 5G version because the SOC of the 4G version (System on Chip/Card, basically the CPU etc) does not support a 5G modem and antenna.
As I understand it, the difference between the 4G and 5G variants is similar to the difference between a Snapdragon and Exynos Galaxy S8,9, etc.
Again, I could be wrong about this and it's just how it was explained to me prior to the phone being released when I asked if it's possible that the 4G version could have the hardware for 5G and just not be enabled until 5G is available in your area, because there was a time when OnePlus was making a blanket statement that the OP7 Pro would be 5G, and said nothing about a 4G variant even being a possibility.

Will a Chinese market Mi 10 Pro and/or Mi 10 Ultra work with UK Vodafone?

Hi there, hoping someone can help with an answer;
I'm considering buying a Chinese market version of either the Xiaomi Mi 10 Pro or Mi 10 Ultra but just wanted to make sure that I'll continue to get decent 4G coverage (and hopefully even 5G coverage) on Vodafone UK.
I realise the CN version of the phone doesn't support or have band 20 which from what I've googled so far is 800Mhz.
I have no idea how phone signal actually works, so with this missing band, will I still get full coverage from the remaining bands the phone does support; B1, B3 and B7?
Does it mean that with 75% of the bands, I'll only get 75% coverage? Do certain phone masts only broadcast in B20, meaning I'd get zero 4G signal if the masts my phone uses fall into that scenario?
I'm a complete Layman with all this stuff (as I'm sure you can probably tell from the above ) so was hoping someone could help me out before I commit to spending a load of money on a phone that wont work here in the UK.
Thank you.

I don't know how Vodafone compares to Three here in the uk, but I've owned quite a few Xiaomi phones , and haven't really noticed any difference in ones that have B20 or not.

Thank you for the reply,
So some of the Xiaomi phones you've had have been Chinese import ones?
And there was no difference in 4g performance Vs global Xiaomi phones? (Just asking coz global versions do have band 20 - 800Mhz)
Thanks.
Incat said:
Yes, but I'm on Three and it might be location dependent too, but I've never had a problem getting 4g on phones with no band 20.
Check what bands Vodafone use compared to Three.
You can buy a global Mi10 Pro with band 20, though the non pro seems easier to get hold of.

That's great, I'll double check the differences in bands used between Three and Vodafone.
Finding a global Mi 10 Pro has been impossible so far, but fingers crossed......
Thanks very much again, really appreciate it.

Already did and still not getting anything. Tried even resetting the mobile data settings and messing with APN and still no 5G. I checked my T-mobile account and it shows that my device is unknown to T-mobile and it says that it's not 5G capable. I think the answer is in T-mobile's own system.

Went to T-mobile store and they told me my SIM is fine and the reason for not receiving 5G or 4G LTE was because T-mobile was unable to recognize the ROG phone 5 in their system. They gave me a phone number to their customer service and asked me to explain to them that the phone is 5G capable and hopefully they can fix this problem.

Yes they couldn't help me as well. The tech support said the phone was not in their system as it's not a t-mobile phone and therefore not possible to get 5G. And for the record the phone is not even receiving 4G LTE. The only thing the phone is receiving is 4G.

This is nonsense why is Asus lying and selling this phone as 5g. With only 4g working this phone is worth only maybe 400 dollars not 1000 dollars plus. Really mad, planning on returning this phone back. Any suggestions guys what latest phone is good apart from Samsung with good speakers and battery life?

Either we wait for Asus official US release maybe they will push an update to fix this or if you have to return it I say go with One plus 9 pro as it seems the most compatible with T-mobile plus it's sold by T-mobile themselves.
There is a reason that so many of the sellers tell you to check the bands before purchasing the device for a specific carrier. It should also be noted that you cannot change the bands with a software update.
You can find the bands on https://www.gsmarena.com/asus_rog_phone_5-10715.php and then head over to T-Mobile and check https://www.t-mobile.com/support/coverage/t-mobile-network#tech to compare
5G bands1, 2, 3, 5, 7, 8, 12, 20, 25, 28, 38, 40, 41, 66, 71, 77, 78, 79 SA/NSA - Version 1 1, 3, 7, 8, 20, 28, 38, 41, 77, 78, 79 SA/NSA - Version 2, Version 3
5G​
Frequencies that can provide 5G:
Band n71 (600 MHz)
Band n41 (2.5 GHz)
Band n260 (39 GHz)
Band n261 (28 GHz)
Version 1 supports 5G just like any Samsung device out there. Versions 2 and 3, on the other hand, only have LIMITED support for 5G and SA cannot be used (Settings -> Mobile Network -> 5G SA Mode)
What this means, in the simplest possible terms, is that you CAN get 5G if the specific tower where you connect provides the band that your device supports. Not to throw salt on it, but Version 2 and 3 also lack 4G band 12, which is the extended range band for T-Mobile.

I appreciate your help. The biggest question I have is how to tell which version of the phone you have. Mine at the time of purchase was listed as I005DA. I think Asus's biggest mistake was not releasing the phone in the US to begin with.
I am sorry for off topic.
I am planning on buying a ROG Phone 5 Tencent Games Editor phone, as this is the only version available to my local stores.
My question is, will this phone get OTA updates in international / global rom?

No it will not as far as I'm aware. But updating it is extremely easy. Just download the WW updates from Asus website and put it in your phone and restart the device and you should get a notification saying your phone has an update press on update and wait for it to finish. Your phone doesn't need to be rooted or anything at all.
I ended up returning it guys, not getting 5g is highly unacceptable in today's world. I got a Sony 1 ii for now it's quite good and gets 5g. Will get the Sony 1 iii in few months once it comes out.

Excuse the rant for a minute, but there are a whole bunch of eBay and other sellers out there passing off their reflash devices as new, which makes it really hard for anyone to know what they bought because you get a Tencent device with a WW ROM and a manual in Chinese with the global apps.
The easiest way to know which device you have is to look in the box where the case and SIM pin were located. There should be a wax paper sheet with two black stickers on it. That will give you the exact model number.
If you got anything higher than 12GB RAM, it's Chinese. The European 16GB release isn't until the end of May and the Pro / Ultimate will come after that. The US was estimated for Q2, but it will also be the 12GB in the first release. If you got one claiming to be US, it's probably European (or Chinese).

SM998U1 does not recognize 5G band in France

Hello, can an expert helping me. I have a sm-G998U1 s21 ultra I paid via Rakuten site.
My concern is that I am not able to get 5G signal, only LTE, knowing that my operator is FREE with 5G in France. My SIM card has no problem because when I install it on an other mobile phone I receive the 5G.
Questions to the expert:
- Is this s21 ultra model compatible with 5G European bands and if yes, how can I customize my phone to receive 5G?
- Taking into account that this model is an US phone, do you think it's possible that I change the firmware via ODIN by replacing the current version SM-G998U1 (US) by a SM-G998B (European) and will this solve my 5G problem?
Or this is impossible even with different firmware because it is due to the mobile hardware, the antenna is different on US models.
Thank you for your help.
Hello, exactly same story with rakuten and SM-G998U1 s21 ultra
No way to get 5G working in France (with Free mobile).
I contacted Samsung Customer service. They told me the product was for American market, so don't expect it to work outside the USA.
The seller says it is compatible but in fact it is not.
I talked with the seller and they tried to explain me that it was 5G even if it is written LTE in the connection icon...
I also tried the tool ForceLTE to restrict to use only 5G (and no LTE) and I never get connected. I show them the screenshot and they realised there was a real problem.
Hello,
I have the same problem in Spain. All work fine, but It can't connect using 5G...
Were you able to fix the problem by installing some firmware or ROM?

Question 5g on ROG Phone 5

I am having trouble with 5g on my ROG Phone 5 I have verified and reverified that I have 5g coverage with t mobile, that it's turned on in the phone, and that all the imei info on my phone is right. Get 4g but no 5g. I am rather new at this so if it's obvious I'm sorry but I didn't see this in any threads I searched for so I'm at a loss.

Are you in a 5g zone? Do any of your family or friends have 5g in that same area?
Even if all of that is a yes, the RoG Phone 5 only has two (out of 4) 5G bands on tmobile (n41 - 2500 and n71 - 600) so you would only be able to get 5G if the cell tower is using one of those bands in your area.
If the tower is using one of those bands and you still dont have 5G then I am at a loss. You can check tower info by using an app like "Network Cell Info Lite & WiFi" or something similar.
The 5G SA/NSA support for TMB and other US carriers are not good due to the lack of bands supported by phone itself (2 out of 4 for US variant, 1 out of 4 for EU and None for CN). had the same problem. No quick fix for it as you'll likely have to swap to a US version to be semi-fully compatible.
Sometimes you'll also need to enable SA in settings for it to have reception.
Another deep hole: even thought both regarded as WW, EU and US var actually have different supports and it's really hard to tell the diff

Yea ASUS is really weird with their versions and one of the hardest phones to figure out. Assuming OP has the US versions, he would have better luck with 5G on Verizon (5 out 7 bands). The global versions and even if you converted a CN version to WW will practically have no 5G.
I have the RoG Phone 5S Pro which has the same version issues as the regular Phone 5 and 5S. I have the US versions and use Verizon so I get pretty decent 5G service in the US.
