Hello,

I'm using Zenfone 2 laser(ze550kl). As u all know it's a dual sim phone and supports 4G on only one slot, the other slot has to be 2G. I'm using 2 SIM cards (4G+4G or 4G+3G)...  I'm facing a strange problem..whichever sim am selecting as  Preferred Network(4G) either sim1 or sim2 in settings... am getting signal on only that slot/sim, am losing signal on the other slot.


if am selecting SIM1 to connect to 4G(preferred data network), on the other slot(SIM2) i'm losing signal, or if m selecting SIM2 as my preferred data network(4G), on Slot1  signal is going down.


I Tried using multiple networks, but getting the same problm on all the networks(Airtel, Idea, Vodafone), another strange thing is am getting signal on both sims(
4G+2G) when m using a Telenor network for 2G slot.

when am trying to manually connect to that particualr network in settings,am getting an error say 'can't connect to this network at this moment, try again later'

i performed SMMI test, it says both sim slots are working fine.

m not able to figureout if it is a hardware issue or software issue. both slots(4G/2G , 2G/4G)  are working fine for one network. I hope somebody will help me.
thanx in advance..



4G on SIM1, no signal on SIM2
