I buy one resdmi 1s to one of my colleague (sigh) because I have a redmi first version with which I am comfortable.
I installed miui 36 versions in Ita and the multilingual one, but in both version have the same problem with the dual sim.

My colleague uses two sim: one for browsing and one for phone.
If I insert the two sim, however, the navigation is be very bad even with perfect reception. In practice it seems that works but then after a few seconds it stops, then works again, etc. ..
If I disable or remove the sim to 'call' the navigation works perfectly.

I tried to insert 'only 3g' in the settings without any benefits.

What to do?

One other italian user has the same problem.
In his opinion problem occurs when it switch from h to h+. How to solve this? Other users hasn't this behavior. What we can do?

Bug correction: We can hope that more users report this, so that Xiaomi and/or MIUI developers priorities this issue and finally solves it.

Internet service providers: We can also try with other Internet service providers. I have tested with Swedish providers:
  • Hallon and its network originates from the provider Tele 3.
  • Tele 2 and they have it's own mobile network.
  • Universal: I have also ordered a new SIM from a provider called Universal and its network originates from provider Telia.
Phone: I have also ordered a Redmi Note and it also have dual SIMs. Hopefully it works better on that phone.

I had a Note and it worked without problems. The same sims on 1s has more or less the same problems you had.
