XZ2 compact dual sim 4G

[Bakacary]

Does it support having both sim cards register on 4G LTE network? Or is it 4G+3G?

Also if call comes in on sim 2 when data is set to route through sim 1, do we lose network access like the current dual SIM phones?

Yes, both sim cards can register on 4G LTE network.
