I read on reddit, some were able to get dual sim working on Duo by enabling dev mode.
Do you have dev mode enabled?

Hi,
I own a Surface Duo and was wondering about its Dual Sim capacity. In my case I need to manually switch (via settings) between the SIM's (one eSim, the other being a physical Sim in the tray). The Sim not selected is not active at all. So calls to that Sim will not arrive.
My Pixel accepts an eSim and a Sim card as well but in that case both are active in a Dual Sim Standby mode. I can get calls on both Sim's but when I make a call with one, the other one it not for the time I am using the first SIm. The Duo, in my case, does not offer this Standby mode as far as I can see.
Can anyone help me out ? Is there a way the Duo can have Dual Sim standby mode ? Are there Duo devices with that option ? And maybe.....will Android 11 bring us that option as I know the Duo 2 does offer it ?
Thx !

2022-04-05T16:27:00+00:00 I believe the functionality for dual SIM operation is in the System on a Chip, which in the case of the Duo 2 is the Snapdragon 888 which provides this functionality (Multi SIM, true Global 5G Multi-SIM capable). The Duo 1 SOC is the Snapdragon 855 and this (DSDV) phone can keep two 4G or 4G VoLTE SIM cards active in your phone in Standby configuration, not Active, simultaneously. So DSDS is not a capability of the 855 although you can have two SIMs (one physical, one software) -- they just can't be active at the same time.
The SOC descriptions are from the Qualcomm web site.

Have you updated your Duo to latest update?
