Samsung S5 dual sim adapter is anybody using this

[Dawse61]

I would like to fit a dual dim adapter to my S5 and i realise only one of the simcards can be activated to make a call or switch to the 2nd simcard. My question is if sim 1 is activated and a call comes in to sim 2 will the phone autoswitch so I can receive that incoming call?

The quick answer is 'no'.

While some dual SIM phones allow data on one SIM and voice calls on the other, the adapter in question operates as a switch - as though you opened your phone and swapped SIM cards.

So only one SIM (and therefore one account) is active at any one time - so if SIM 1 is active, then the phone is only listening for traffic addressed to the account associated with that SIM. The traffic to other account is ignored and it is as though that second account's phone is 'off'.
