AC Question
I have recently bought a Galaxy Note 5 Duos (model SM-N9200). I decided to get this one because it was dual sim and to make sure that I could use my two sim cards in Japan, (one is English, the other one is Japanese). I bought it in Hong Kong, and they confirmed me at the Samsung official store that it should work just fine in Japan with both SIM cards.
Unfortunately, I don't seem to be able to enable the 'Dual SIM always on' option. I got a message that Call Forwarding and Call Waiting failed for both SIM cards.
It also seems that only one SIM card can be active at a time, the one that I specify to use 3G/4G. It makes sense to have just one active data connection, but I don't understand why I can't receive calls in the SIM card that is in 2G only. If I change 3G/4G to be enabled on the other one, then the first has no signal. They both operate on the NTT Docomo network, but not concurrently.
Could anyone explain how this works and why I can't enable both SIM cards to make and receive calls?
Thanks
