Hello.
I have an OP7T HD 1900 Chinese version. I flashed an EU ROM.
I have a little problem. One of my SIM cards does not have its services that are detect.
In fact all services associated with it / visual messaging / VOLTE VOWIFI etc ... are unavailable.
If I do the key combination * # * # 4636 # * # *
to access the developer mode, I read that it was possible to change the radio band by pressing the 3 small dots in the top right. But the possibility of changing the region of the radio band is not available.
My IMS (SIM card services) is unregistered.
In fact my SIM card and the services associated with it are not detected.
I put my SIM card in my old phone (redmi note 7) and everything works perfectly.
Hence my question is it possible to change the Chinese radio tapes to put it in European version. Or manipulation to force the services to take into account my SIM CARD?
Thank's

What operator are you on? I use Bouygues (B&You) and I can't even find the setting for volte or vowifi. Visual messaging works though, through integrated visual messaging app (phone app).

Hello.
I am on SFR network. I can access SMS calls. All the rest nothing works call transfer (unexpected network response ...). With the other operator it works. Only with this operator, the problems mentioned above.

Do you have the proper APNs listed for that network? If they're not listed, you may have to add them manually. You should be able to Google for the APNs for your network.

Dears,
Am in the process of researching/buying an HTC M8 dual SIM phone, can someone please advise if it is feasible to STOP Mobile DATA on a certain line (Ex: Line1) and ENABLE Mobile Data on the other line (Ex: Line2).
Thanks for all your help.

Bad dual sim management
Better late than never, right?
You find "dual sim management" in the phone's settings.
This is where you can activate and deactivate each sim and where you set the preferred sim for mobile data.
So, yes, you can easily switch the sim that's being used for mobile data.. However, the BIG restriction is, that the sim 2 radio only supports 2G (up to EDGE). So, in order to use high speed internet from the provider whose sim is located in slot 2 you actually have to swap the sim cards. Also, there's no way to automatically switch to the other network's mobile data in case you lose mobile data coverage on the preset network . You really have to tell the phone manually which network to use.
Another big issue for me is that I can't preset the network I use for calls. So, my sim 1 is for data only. sim 2 is for voice calls and texts. Remember: it has to be this way because only sim 1 supports 3G/4G. Now, when I initiate a call via voice or via my car's bluetooth unit the phone automatically tries to use sim 1 as the default for calls. I can't set it up to use sim 2 as the default call handler and there's no dialogue asking me which sim to use like when I dial manually. That's really bad, all other companies that offer dual sim phones have better management options in their software's settings.
I tried using alternative phone apps which give you the option of choosing a default sim for calls but this only works for voice-dialing; bluetooth still overrides the alternative dialer and always goes with the stock one.
I hope this helps - so actually I'd advice agaist the M8 dual sim despite it being beautiful and having really good hardware.

This is likely because the provider doesn't support enhanced features, or doesn't support enhanced features on your plan. I didn't have the enhanced features available with AT&T, after switching to T-Mobile the Enhanced Features section then became available and I was able to enable voice over wifi and volte.
I can't see Enhanced features... TR Turkcell and Vodafone TR?
There's no thing as "Enhanced Features" in 4.0.2. Once you select Jio as your primary data sim, you can see the option of "Use VoLTE when available" and you just have to turn it ON.
Selected Jio as primary data sim
Even though I selected Jio as a primary Data sim I am not able to see use VoLTE when available
Change Sim Card from 1 to 2 or vice versa...??

Is your default sim for cellular data set as jio sim. Plus checking sim options like data roaming and checking apn settings seems to be the only option, before full wipe and refresh

Yes... my default sim is Jio only, i am getting the internet but not getting the VoLTE option to make calls
Ok, and advice appreciated.
Have just put a SIM in the second slot in my G5. Am running a Vaya SIM (voice, data, sms) in the actual primary slot and a Telstra (voice only) in the second slot.
If i select the Vaya as primary SIM for all three (voice, data sms) in settings it works fine.
But using an app (Dual SIM Selector) to select what SIM on a call by call basis, it wont send or receive calls on the Telstra SIM and tells me mobile network unavailable for voice calls.
If i go to settings, and set the Telstra SIM as primary for voice, data and sms (needs to be set for all 3 regardless no data plan on that SIM) then i can make and receive calls from the Telstra SIM no probs.
So both SIMS are active, and both SIM slots work with a 3 or 4G card. Have swapped SIM cards in the slots and all as above. SIM cards are good and slots both work.
What i was hoping for with a dual SIM phone was for the Vaya SIM to be active for making / receiving calls, SMS and data as normal, but for the Telstra SIM to be "listening" , be able to receive calls , and make calls when selected on a call by call basis.
Now,being in Australia and having had the 2G network shut down late last year (3 and 4G only now) i am wondering if that has something to do with this??
Anyhow, wondering if there is anyone out there who knowing more about this dual sim thing than i has any ideas??
Hmmm........did some checking and think my problem with the dual sim thing is due to the 2G network on telstra and optus being shut down.
Seems under the software on the G5, whichever SIM card that is NOT set to handle mobile data, tries to default to 2G as preferred network (under Settings / More / Mobile networks) and the "Preferred network type" button is greyed out and inactive.
Of course no 2G network when you try and make a call it tells you no network available. Sadness.
So, unless Motorola come up with a fix, or deal with this in their next update for Australian phones, i think i'm stuck on switching between SIMS, and NOT having the second SIM able to listen out and receive calls, which even if both SIMs share a radio seems a no-brainer capability to have to me. Have sent a begging email to Motorola asking if they have a fix / workaround and would they consider thinking about this for next update? Pretty much all i can do, although if there are other Australian users with similar issue wouldn't hurt for them to contact Motorola support as well??
Anyone know how to set up a "shortcut" direct to the SIM config page in settings?? App or widget for that??
Am hearing on the G5 Whirlpool thread that there is an update / fix in the works and maybe on the way from Motorola to deal with the dual sim issue (defaulting to 2G) on the Australian G5.
Got the below from Motorola support today. So, fix is on the way.
Good day!

In "Select network type" in "SIM card and mobile network" of my RN 9T, for SIM1 there are only 2 options (LTE and 5G) while SIM2 has all network types (2G, 3G, LTE and 5G). Moreover, VoLTE option for SIM1 is greyed out and cannot be activated/deactivated. I do not understand why my SIM1 has only 2 options and VoLTE is greyed out. My MIUI version is 12.0.5.
Anyone has the same issues? Kindly share how to solve this problem.
VoLTE * # * # 86583 # * # *

Thank you for your advice.
Those codes were already used to activate relevant services. But the problem I am having is not that. Please read my description again. Btw, which version of MIUI are you on now?

Hey there bud, try this *#*#4636#*#* and it will take you to a different screen then select the first phone selection like in my case I'm using 2 sim cards, scroll down to SET PREFERRED NETWORK TYPE and select anything you want from the drop down. Good luck bed.
My MIUI version is 12.0.4 QJEEUXM , for me it is active on sim 1

Do you have or can you borrow a different sim from a different carrier and put it in that slot, then try checking it again? I don't know where you live but sometimes in the USA (where carriers get away with murder) the carries disable/gray out/hide menus, etc.
For example, in the USA, even after using the codes above to disable carrier checking for Volte and Wowfi, only Volte is enabled, because wifi calling must be turned on by the carrier.
It seems very odd that you can't set the preferred network, I know, but I also have this issue on an unlocked by ATT branded LG phone in the USA, so it's worth switching sims to see if anything changes.
Good luck!
You are right.

You are right. I did as you advised and all network options are shown and volte is not greyed out. It is indeed a problem of the carrier, not the phone then.
Thank you very much.

pardon me, you probably know this already, but just in case (cause I made this mistake myself) -- carrier checking has to be DISabled for features to be enabled. (I thought it was the opposite for a very long time).
Before OnePlus 9 Pro I used to have Huawei P30 Pro that automatically switched Mobile Data to SIM card that was used during a call. It gave me an ability to use internet regardless of SIM used for call (important scenario when driving, for instance). It's noteworthy that none of my 2 carriers support VoLTE / VoWiFi. Now for OP9 Pro this mission became impossible and it feels like a downgrade compared to 3-4 yr old phones.
Is there any solution for this? Maybe custom ROM, hack, whatever...
So at the moment you have Sim1 with data and Sim2 without data?
In settings you can set your preferred Simcard for calls, messages and Data.
Does setting Sim1 as preferred Simcard for data not work?

My both SIM can be used for Mobile Data if I select explicitly, and regardless of preferred card (1 or 2) for data, I can't get data working in case I call from the card that was not selected as a preferred one.
The switch in SIM settings that says there must be VoLTE active on second card in order to make data working during a call from first one does not help. Simply because there is no VoLTE available from carrier.
For instance - I have preferred card SIM1 and I call from SIM2 (and need phone to switch to using data from SIM2 during a call), in this case during a phone call I have no data available at all. Very inconvenient in a car (navigation) or just if you have to check some info from internet during a call. Previous phone allowed to use such feature without VoLTE (same cards, same carriers), OP9 Pro doesn't. I wonder if it's a software limitation or hardware.
I am looking forward to change OP9 to Mi 11 Ultra now due to this... ((
My model is LE2120
VoLTE is unchecked in settings?
Otherwise, no idea dude...
Maybe check in Oneplus forums?
Hi I'm in almost the same situation like you.
The only way that i thought it can be done on the op is using tasker.
If you know how to use tasker and manage to do it, please let me know
Tasker will wait for and event like receiving a call, identify which sim the call in coming on, switch active data to the same sim the call comes in on, and viola
I've opted for the most radical way - switched to Samsung S21 Ultra. It was hard to tolerate such caveats like absence of mobile data auto switching, mid-end camera & fast-dying battery in flagship phone...
