Sim 1 and Sim 2 (How the 4g work?)

Inanimado001

Good afternoon, first at all sorry for my bad English writing, is not my first language.

I want to ask the community if the is a different in the reception signal between the SIM 1 and the SIM 2 with the LTE

I went into the engineered mode and the system only shows LTE information for the SIM 1 and not for the SIM 2.

I just want to know if there is a possibility that the SIM 2 does not work with LTE and if that is the case, Does there is a memory that fit in the slot two? which type will be?

Thanks in advance, and again sorry for the bad English.

With Android 6 ROM,  one slot can be 4G, the other 2G. But:  Not all operators have a 2G network.

Nougat is supporting up to 3G and other 4G on standby mode. Both slots are supporting 4G but not in same time. You need choose from system option. In marshmallow is 2G and other up to 4G.

Hi there,

for me LTE works with SIM2 as I use a SD-Card in SIM1. But SIM2 does not support all bluetooth features as RSAP.... (look at my other posts)

By me, LTE works with SIM1 and SIM2 comparable.

When I have one sim in my UMI Super in slot #2 (the one nearest the inside of the phone), then 4G works - everything works fine with one sim.
If I put a second sim in slot#1 (outermost slot), then slot #1 works on 4G but I can't use slot #2 for messaging, because it seems to revert to 2G
If I swap the sims, it comes up as 3G on slot #1.
WTF?

With Android 6 ROM,  one slot can be 4G, the other 2G. But:  Not all operators have a 2G network.
I have two networks,  (Telia and 3 in Sweden). Telia has 2+3+4G. 3 only has 3G and 4G frequencies. So I must use my 3 SIM as data SIM. If I set my Telia SIM as data SIM, the 3 SIM switches to 2G which 3 doesn't support.
If I've read things correctly the upcoming Nougat ROM allows 4G on both SIM slots simultaneously.
