Help Internet connection stops after a while, when using 2 sim cards

[danezeq]

..To restore internet connection i have to enter into flight mode and then stop it (or restart etc..)

My phone is Redmi, android 10.
Im using 2 sims. the secondary is a prepaid without outgoing calls and data.
The internet is defined to use only first sim.

if i eject the secondary sim the problem stops. if i use another secondar sims from a friend, the problem stops again.
What can cause this issue?
