Dual SIM support in ROMs

Good morning,
I have a simple question : are any of you using dual SIM with custom ROMs ? I heard LineageOS/CM has support for it but I don't know for K5. Have you experienced it ? Any issue ?
Thanks.

I think all the ROMs has dual sim support.

I used A6020a46 flashed LineageOS/CM 14.1, both sim working fine, but not yet trying VoLTE. Im not own sim with VoLTE supported

AOKP
Using AOPK in l36 variant, dual SIM works fine.

That has been asked hundreds of times already. Whatever happened to search first before asking?

Volte is not supported in lenovo p2 on linage is 15.1

I am using custom ROM linage OS 15.1. Having two SIM. Fist SIM slot holds JIO SIM and second holds Vodafone. I am not able to make Volte calls. Please help.

I m also on lineage os 15.1 official treble version. Volte works just fine. Check your apn settings. Try adding ims to your apn type. If nothing works try reflashing stock s251 followed by lineage os.

Need help - SM-G960U1 Jio VOLTE not working

Hey Guys,
I am from India. And I got an S9 gift from USA.
Jio volte doesn't work on the phone.
After intensive research I concluded I need to flash a stock indian firmware for Jio Volte to work. (There could be a better way I am not aware of)
My phone model is SM-G960U1 and on SAMmobile No Indian firmware is available for this model.
This is a Snapdragon Phone. Single Sim.
Please guide me. What firmware/process should I follow to have Jio Volte work on the phone.
Thanks in advance

I am facing the same issue since a few months now. I did try a few different firmwares without any luck. Were you able to get a solution to this?

I am also desperate to make my T Mobile US S9 work in India with Jio. I don't see any detailed threads for S9. I see steps given only for S8 to enable VOLTE in a US snapdragon based phones.

Apparently, there is no solution available to this problem so far. Sadly we can't flash any CSC outside of USA just yet. The problem is two fold, Indian S9/S9+ variant is a dual sim version with exynos processor whereas, the US variant is single sim, Snapdragon based device. Moreover there are only a bunchful of users like us so the likelihood of getting any future support from Samsung devs is very less

Can provide more details and links to the build.
I'll try and work something around and see what happens

Until or Unless we change salescode.dat to INS and flash indian csc file , we cannot get volte in our phone. i had same issue with my s8 us variant but with engboot i had change my salescode to "INS" but for s9 it has patched and we cannot change country code without any additional permissions

To get on to this build you need to be on oreo ARI6, u have to flash it via odin and then flash zrj7 wjth recovery

There is no INS for snapdragon when i went through csc list only GCf was working through which i could get volte working for airtel service provider

Any custom rom for Oneplus 7T HD 1907 with dual sim support

hi i have successfully converted T mobile oneplus 7t to global firmware dual sim variant. OOS 11 shows dual sim.
but when i try any custom room like pixel exp or yaap etc then only show single sim not dual.
is there any custom room with dual sim support for hd1907?
thanks

I’ve tested LineageOS 18.1 and it doesn’t support dual-sims, not sure about any of the others.

I tested LineageOS 18.1, too. It does not support dual SIM for HD1907. It is shown as HD1905 in "About phone" settings. I guess this has something to do with only one IMEI in this model. Normally a dual SIM phone has two IMEIs, one for each slot.
