Buying a different version device. No other way.

you can activate by contacting your provider, and asking them to activate your 5G capabilities. A $10(per month) charge will appear on your bill. The 5G display on top of phone will appear when the area you are in an area(only a limited number of cities) that has 5G. Your phone will automatically change back and forth.

On the KOO version you MUST use a korean usim, otherwise you will never enable 5G network.

EU VoLTE on SM-G7810

Hello!
Did anyone manage to get VoLTE and VoWiFi to work with any EU carrier and SM-G7810? I have the options enabled in settings, but, unfortunately, I think the phone does some sort of carrier check(my carrier is Orange RO). As it seems that many people in Europe bought this phone as it has 8 GB RAM and it tends to be rather cheap, has anyone been able to get VoLTE to work? The bands are okay, and in my case I know it's not a carrier issue(I had Xiaomi phones which were also not supported officially by the carrier but I called them once and told asked them to just enable VoLTE and VoWiFi for me and from that point on it worked after I disabled the carrier check on the Xiaomi phone). In my area I have poor 3G and 2G reception, but very good LTE band 20 so VoLTE is quite important for me.

Hi, do you fix it ? I have also the same problem.

After clearing Carrier Whitelist VoLTE is working for me on DiGi and Vodafone Romania . IT also works Digi 5G that doesn't have extensive coverage .
What strangely doesn't seem to work is B3 2CA on Vodafone , strangely it works B3+B1 but not B3 intraband.
Also the good thing about the phone is the existance of B20 that really works even the phone is HK, China model

Hello. Can you please tell me how you cleared Carrier Whitelist? I can't find any information online. Thank you.

Search XDA as it is in the service menu and it is used generally for 5GCarriwr Whitelisting.

Question No 5G

i cannnot get 5G with my X3 pro ,
only 4 G +, i have global Version , i am from Austria (Magenta) ,with my iPhone 12 there ist no Problem with 5G, what can i do, regards Nico

Ask your carrier. Your phone might not be yet supported by the carrier when it comes to 5G. Usually carriers support firstly iphones and samsung phones....then over time the compatibility is extended to other phones.
In addition double check if you have 5G enabled:
Settings -> sim cards & mobile data -> choose SIM -> Preferred network type.
You can also get a SIM replacement (even if 5g was working on iphones it might not on other phones due to some SIM incompatibilities)

thank you for your Information

ich found it on Reddit
i have 5G now , I am very happy now

Thanks very much. This helped me, too!!!

I envy you, I am very often in the countryside, father is a farmer. Therefore, my maximum is 4g.

Does it also enable 5G SA (Standalone)?

@nico1885 what did you do to enable 5G?

I have a similar problem, I have a dual sim UK BT + Vodaphone although my issue is with the BT sim (standalone or in dual sim). I can get 5G on the BT sim when I swap the sim in and install the APN, sometime later 5G goes away and 4G is all I can get. Strangely this happens on my Find X2 too, I have no problem with 5G on the (many) phones I have. Vodafone seems to get 5G all the time. The BT sim is 5G ready.
Not sim settings have the 5G/4G/3G setting......but once 5G goes away it doesn't come back until I provoke it by say swapping sim1 to sim2...but it will go away at some time

Does it enable 5G STDNOL???

STDNOL, do you mean SYMBOL?
Yes it does show the 5G symbol for the time 5G is on, then 4G/4G+

5G network can only be enjoyed if it's available in your region. Kindly contact your Mobile Operator to check if 5G is available.

i am oppo user but my country have no sppoted 5G technology: Minecraft

Question Mi 11 ultra no 5G cellular network [ stock global ]

Hello everyone,
I've just upgrade my plan to have 5G support, but the phone does't pick it up ( the carrier says it's ok )..
I also searched manually for networks and I find every network even from other provider but NOT a single one with 5G.
obviously I am in a 5G area, center of Milan, and sim slot 1 ( but I recall that was dual 5G, no? )
It's a bug, broken or I played with some setting disabling 5G?
thanks
EDIT: SEEMS LIKE THAT switching preferred types, airplane mode, while outdoor made the phone to connect t o a 5G antenna...
funny note, it's slower that 3g: 5.69mps/0.59mbps

Might need to enable it

you mean preferred network type? always been in 5G

Try to reset apn configuration and all kind of connection, then switch off the phone for 1 minute and reswitch it on

If you have the chinese model (not EU or global) you might have some 5G band limitations, and it's also to be taken into consideration which bands your operator is using in your area.

Question SM-G998B no carrier aggregation, help needed

So i bought a sm-g998b (s21 ultra) from australia (telstra) and came to estonia, and here i dont have any carrier aggregation, volte, vowifi, doesnt work, no 4.5g, no 5g, i tried switching bands to european but it says unsuccesful with all of the bands, is there a solution for my problem? eg changing out the firmware or something else?

Everything is absolutely normal - a quick Google search would have told you the same.
Estonia doesn't have a 4G network (*country coverage is approx 2% for 4G).
- You'll have a few 4G cells in the center of Talinn
- Since 3G doesn't have VoLTE (LTE=4G), everything is in order.
- VoWIFI won't work either, because *most* of the time, the wifi network must be on your carrier broadband box.

You're wrong. Even your link shows, that the coverage percentage is definitely higher than 2%, in addition to the fact that this map only contains community-provided data, which might not cover all areas.
All 3 telcos in Estonia have about 99% of coverage of the whole country, two of which (Telia and Elisa) also support VoLTE for certain phones and Telia (also building 5G using DSS) supports VoWiFi.
You can take a look at CellMapper [1] and see, how many 4G towers there actually are in Estonia.

To OP: Are you roaming or using a local SIM card?

you are completely wrong, estonia have had 4g+(lte-a) since 2011-2012 and coverage is 99.9% of the whole country, i have had volte and 4g+ work on my xperia xz3 since 2012-2013, i have local sim btw, i am from estonia, 2% can be for 5g rollout but thats not the issue right now, issue is i dont have any carrier aggregation on my s21 ultra and on my gfs s20 ultra, i have mine flashed with odin to SEB latest firmware but that did not resolve the issue, when i go into mobile data service menu it only shows one tower connected there and i already talked with my service provider they said that i should have at least 13 masts covering my location with perfect visiblity + all bands covered so i should be getting at least 6-800mbps (according to their test they ran on my location, yes my isp is doing tests on actual on site locations to help clients), so if anyone has any ideas as what could be wrong or should i flash any other rom on it or something? i am out of ideas, i though firmware flash would fix my issue
