K8 Note 7.1.1 Unable to use both 4g Sims at a time.

2017-09-07, 10:48 AM

Facing problem with 4g sim slots.

1.am using jio(volte) in sim 1.

2.using idea 4g in sim 2.

3.set preferred network for data is sim 1.

Here i observed issues,

- if I switch mobile data to sim 2(idea 4g) am not getting signal on sim 1(jio).

-if i switch mobile data to sim 1 am getting only 3g network on sim 2 (4g network not showing).

 

Finally if we use jio sim in one sim slot we unable to use data on other sim.if we switch ON data on second sim than we lost signal on sim 1(jio).

So lenovo k8 note not suitable for dual sim if one sim is jio.

 

Lenovo need solve this problem ASAP with updates.

Hi Ravisurspaneni, 

 

4G data will not work on both sims simultaneously and 4G only works on Sim 1 slot.

We can do Reset Network Settings. Go to Settings> Back up and Reset> Reset Network Settings. Hope this helps!

Hi,
Even I am also facing the same issue with jio and idea sim combination.
When one sim is in 4g mode the other works in 3g. So, when you turn on 4g data on jio, idea switches to 3g mode and shows up signal.
But that is not the case with jio as jio cannot work on 3g. So, when u switch back to idea4g and turn on data, jio will be turned on in 3g mode which it won't work,. That's why there is no signal.
I think this device is not a dual 4g standby.
Beware when you buy it

Hi sriganesh16, 

 

This device doesn't support 4G data of 2 sims at the same time. Sim 1 should be 4G and the Sim 2 should be on 2G/3G.

hi,

then you people has to say the specification proper to us. In all the sites they have mentioned that its a dual 4G standby. if you people mentioned it then we me mite plan for other model.
this is the point in amazon "Dual nano SIM with dual-standby (4G+4G)"
please check the below link
