I Have a Jelly Pro, it works ok, with the new Updated Android 8.1.0
The phone can't work on both SIMs on 4G (neither 3G), I can set only one SIM to 3G or 4G, the other SIM works automatically on 2G.
Is ther a solution?????
Do ATOM Phone is better and works on 3G on both SIMs???
In my country (Uruguay) this is not a problem, because I'm lucky and there are so many old phones that all the providers have antennas with 2G, 3G and 4G (LTE).
I thought that it was the same all over the world, but I was wrong.
In other "civilizated" countries is different, like in USA (I tried with T-Mobile SIMs and AT&T), that my phone only works in 3G or 4G, there's no more 2G antennas (I tried in NY, and in Florida).
I also TRied in The BAhamas and I had the same problem, NO SIGNAL ON 2G, So, the "DUAL SIM" don't works, I Can only connect One SIM or the other, not both at the same Time.
I don't need mobile data on both SIMs, I only want to make calls and receive calls on both SIMs
EXAMPLE: If I set "mobile data" to SIM 1, I can set SIM 1 to 3G or 4G, and SIM has no Signal, because there is not a 2G Antenna in the area,
If I set "Mobile data" to SIM 2 is the opposite, I Acan make calls with SIM 2 in 3G or 4G, But SIM 1 has no signal.
Is ther some solution to that?
