sim issue with aqua m4 dual sim

[joelenvoyage]

Sim1 and sim2 don't seem to be the same. With the same sim card I can get data only with sim 1 whatever the tuning. This I tried with 2 operators, namely, free in France and mobilis in new Calédonia
Is there a way to resolve this issue?

I think it is due to the tech used, afaik, they support DUAL STANDBY as opposed to DUAL ACTIVE, https://en.wikipedia.org/wiki/Dual_SIM
