Second sim is not available, when you are using the first one (when answering/making a call).

...and if I am surfing on socials like Facebook in SIM #1 does it work receiving call on SIM #2 or is it stopped?
EDIT: solved

Similar to the Huawei Mate 10 series, the P20 and P20 Pro can support dual-SIMs with dual 4G and dual VoLTE running at the same time. This provides the best dual-SIM experience as both lines are connected to the best network possible. It also supports download speeds of up to 1.2Gbps with 4X4 MIMO over a 4.5G LTE network.

This all depends on whether you have the dual sim version of the P20 Pro. Most UK versions are single SIM only. Allegedly, these can be converted to dual sim using a guide available on this forum or using the funky huawei paid service. I am still looking for full verification that this workaround is fully functional or not. Goes without saying that, you will also need to buy a dual sim tray for these UK versions of the P20 Pro.

Oh, I'm in Sweden, and my dual SIM works like a charm. Have my work sim and private sim running simultaneously without any issues at all. I opted in the settings to run the surf on sim 2 since I have more data on that one even.
I do wish I could set one number at "do not disturb" at a time. Or change the ringer to vibrate or silent for just one of the phone number.

Still only dual sim standby and not dual sim active so it could be better

@OP
What this guy said is 100%
The only way to obtain dual SIM from a single SIM variant is to essentially lose bootloader unlocking ability by using the funky Huawei method.
It's up to you to decide which you think is more important.

What's the difference between active and standby? Plus, did you rebrand your phone after network unlocking it? Did it affect the network unlock at all?

Uhm, well. Mostly here in Sweden the phones are unlocked and unbranded. So, I just smacked my work sim and private sim in the phone and activated the "dual active 4G" option.

You dont. Try to make a call from sim2 when sim1 is engaged in a call. Or be on a call on sim1 and and get a notice when someone calls you on sim2 and change to that call. You cant do that and that is the difference of dualsim standby and active. The last Huawei device to have dualsim active was the Honor 8. After that they have stopped supporting it, cheaper with standby than active

Yeah that works. If I'm in a call I can add a call using the second line without the first call dropping out. The first call can't hear me tho, unless I switch back. But, both are connected, just the the speaker and mic can only be connected to one at a time. I figure that's a software limitation tho.

Strange that your phone can make it but not mine. And since the phone just supports dualsim standby and not active it should not work. Thats why there are an option to forward calls to the other sim when the the first one is engaged in a call as it is not possible to have both sims active at the same time as the phone just got one radio part.

I actually just tried after the last comment to make sure. And it works. It might be because both of the cards are on the network provider "3" and they do the calls over 3g and 4g since they don't have 2g access. And as my earlier screenshot shows, you can have both of the 4g's active at the same time.
But if you're right about that "one radio part" shouldn't that also be impossible? I'd think it's weird to build in two 3/4g antennas and just one 2g.

Sorry I have to revive this dead topic.
Is there an updated list of DSFA smartphones (dual sim active, two radio modules)?
I know DSFA can somehow be "emulated" using VoLTE /dual VoLTE or VoWifi if the device and carrier supports it.

please help me for enabling volte setting in my device to use volte service provided in my country india

Go to your network provider shop and ask them if they have enabled it for you .. You MAY BE need different packs .. or deals from Your OP
I just put EE-uk into Mate 9 (right) and it automatically showed option wifi-calling.. If I would remove EE sim it will goes away..
And there is calling over WiFi or 4G.. It is little bit weird that 4g network is packed in to wifi calling.. Which clearly is not
It should be separated option.. But it is just the way how wronlgy EE operator did it..
On the left it is P9 but I did it force way as it was patch applied because I was rebranding P9 to China and flashing oreo so patched VoLTE option.. It wasn't there previously in android 7

Dial *#*#4636#*#* and see if you can enable it. If it is grayed out, it is not supported.

Technical department from Orange Romania informed me that Nokia didn't developed the software yet to support VoLTE and VoWIFI on their network.
"Am luat legatura cu colegii din departamentul Tehnic, iar acestia ne-au spus ca producatorul Nokia nu a dezvoltat un soft care sa aiba acces la VoLTE sau VoWi-Fi, asadar, acesat este motivul pentru care telefonul Nokia 8 nu se afla in lista de pe site-ul nostru."

It's not exactly Nokia fault, but network provider.
For example.
On my ta-1012 with EE card in, all of the options are highlighted, apart from the bottom one.
With three network sim inserted all of them are grey out as three offers their own solution for WiFi calling by additional app.

I don't know who to believe. Orange Romania blames Nokia for not developing the needed software, Nokia says that it is carrier depending.

Being on Vodafone, model TA1012. I do have VoLte and VoWiFi.

TA-1012, Vodafone Australia
VoLTE working is working for me.
So it would seem that Nokia's side of things (at least the core functionality) is already in place.

I don't have vowifi or volte indicator but i have wi-fi calling and changing it from wifi preferred to mobile preferred changes the vowifi to volte

"VoLTE provisioned" is off - Mi 9T Pro

Hi team,
This is a Global Mi 9T Pro, Miui 10.3.2, bootloader is not unlocked.
LTE 4G works, however no "voice over" - it reverts to 3G for voice calls.
*#*#86583#*#* results in "the number you have called is not connected", using both SIM 1 and SIM 2, have tried 2 different SIMs that show "VoLTE" on Reno Oppo Z and GS8. 4G switcher app shows "VoLTE not provisioned". Any suggestions on how to enable VoLTE? I have tried a factory reset once...
Thanks
(I can't add links - it's on imgur slash YFFWVNu )

I'm in Brazil carrier Tim, unfortunately there's no specific MBNLoader file for this carrier, so I selected the generic Brazil MBNLoader, it wasn't enough to turn ON VolTE in calls though, it reverts back to 3G or 2G
any other ideas?
PS found a post on another forum that says the Malaysian MBNLoader will be fully compatible with the carrier TIM on Brazil. I tried it and it worked perfectly, now I have VolTE. GG

If you are "roaming", does it switch by it self to proper MBNLoader? (if my question make any sense?)

I think what you're asking is if the MBNLoader changes automatically depending on geolocation or when a new SIM card is inserted. TBH I don't know. But if I would have to guess I'm guessing it is a setting that you select when turn on the device for the first time, and that remains selected even if you insert a new SIM card. Lemme know if i've misinterpreted your question.

Here also. As a workaround you can disable VoLTE Carrier check (*#*#86583#*#*). This works at me.

For me it appeared in the settings with the update, but still cannot activate it

For my case, VoLTE was operational before the upgrade (using 10.3.11 international version on my Mi9T in Vodafone GR). An icon was displayed for VoLTE on the carrier signal in my mobile's screen when it was connected in 4G.
Now it does not work anymore (upgraded yesterday to MIUI 11.0.1 international version, no icon when connected in 4G networks and actually drops to 3G when performing a call so it gets circtuit switched and not IP based via IMS). Of course it is not a matter of settings to disable carrier checks (as already done/undone several times, reboot etc, since it was in disabled state already and the settings are there to enable/disable VoLTE and VoWiFi).
VoWiFi still works but only when using Vodafone's application for WiFi calling.

Contact Vodafone GR (even their website and use chat to request VoWiFi/VoLTE service for your mobile number), they will handle it. Meanwhile you can also use *#*#VOLTE#*#* and *#*#VOWIFI#*#* settings to check that are in disabled state. You should be able to see VoLTE and VoWiFi settings (enable/disable etc) in your Sim cards & mobile settings (pick your Vodafone SIM settings then).

Edit : VoLTE is activate...but don't work.....

Hi, I got a Mi 9 SE. I activated volte and wifi call with the codes under MIUI 10 some weeks ago. Volte and Wifi Call worked like a charm.
Now I received the Miui 11 update some days ago. Unfortunately Volte and Wificall stopped working.
Reentering the codes worked, but with enabling Carrier check again ...
Strange thing is that in settings the option to enable Volte and wifi call is still visible and activated - but I can't see the volte logo und it obviously doesnt't work ...
I read in another forum to do a factory reset might help --- but it got a lot of installed apps etc and I am not willing to reinstall everything ...
Anyone an idea how to reactivate?
Thanks for help!
