how to enable 3g on sim 2

[dariodip89]

Hello, this is a great community and I really love miui rom,
I have bought a jiayu g4 and I have successfully flashed miui rom on it,
the only issue I have is 3g option doesnt exist on sim 2,
I have 2x H3G sim ( here it is called 3ITALY), and they work only in 3g mode
so right now sim 1 works sim 2 cant.
Ive read that other custom rom does the job but I dont want to remove miui
(I know that miui 3.9.20 was able to perform this thing)
any help is appreciated, better how to guide.

I have to admit, I can't get any data at all on sim 2 but I thought it was me not doing settings properly!
I don't need to use any data at on sim 2 though, sorry I couldn't help
