EG25-G MPCIE with SIM adapter and MINI MPCIE EVB KIT

I bought an EVB KIT for mpcie modules and an EG25-G with sim adapter on the back.
The evb kit has a sim holder too.
I was wondering if there’s a way to use the both of them as a dual sim device.
I’ve tried with two sims but I get a connection error.
Is there a way to enable dual-sim functionality with my setup ?
Thank you upfront for any information.

Dear 37TS,
Thanks for your inquiry in Quectel forum.
Please note that EG25G module just support one USIM interface, cannot use both of the two SIM holder. Thanks!
