Problem with Internet when they are installed 2 some cards. With one simple card in first slot Internet speed is up to 22 Mbs, when second card is on aswell than Internet speed is up to 12 Mbs. Phone is after service and they replace Internet module. It is little better but still much slower. Maybe someone know what I should do with it?

Ok, now that I reached home I had time to do some tests and the results are interesting:

- On LTE connectivity: One SIM card speed = Dual SIM cards speed

On WCDMA (H+) Connectivity: One SIM card speed = DOUBLE Dual SIM cards speed

So I have the same like you but I can not check lte. You think that is correct? I will ring again to costumer service

So I called them and they said it's not normal. the phone requires service because the speed may be slower but not twice.
