If you get one that is not defected meaning both sim slots work Yes both will work at the same time meaning you will have two sim cards in the phone at the same time but different numbers. You can receive calls and make calls from both you only switch from sim1 to sim2 each time you want to make calls its your choice now depending on what number you want to call from. It is very easy and nice if both sim cards are working but one of mine didn't work.

Dual SIM feature allows you to operate 2 separate phone numbers from the same hardware. They are both usually active to receive call. Of cause you can only answer one line at a time.

No, this is a draw back of this phone. also duel sims only one can be used if you want good connection to server. if you have two sim cards in the phone is very slow and signals are weak. i only use one sim and works ok. not the reason i bought but it works.

If you meant mobile sim, then the answer is yes. However, I was only able to use one sim card as the phone was not recognizing the second sim. A Samsung dual sim phone I brought is however recognizing two sim cards at once, and works really good.

It is dual sim, one card slot is normal and one card slot is micro sim like use galaxy s3 o s4.

Based on the defn of both, I will say this phone has the dual active sim feature. I can easily switch between sims for making calls and texting, by pressing the desired one I want.

The way it was explained to me is one SIM slot is just the GSM bands and the second SIM slot has both GSM and HSPA+ bands. This same person told me, at T-Mobile, that I had to have one GSM SIM for phone and text and the other would be for data. So this is what I was told this is what the dual SIM slots are about, but truthfully I do not know except the N9002 if extremely popular and sell a lot of them. By the way he never got my data to work and finally I too my phones to another T-Mobile store where the guy said, ""why do you have two SIMs?" After he took out the GSM SIM card out the phone's data worked ever since. so like I said I'm really not sure only that lots of people want the N9002.

Yes you can use two SIMs simultaneously. I have an AT&T and a Philippines SIM card in the phone and I can receive text and calls in both SIM without doing anything. It is dual active SIM card phone.

You don't need two sima just put one sim and you are good to go just select sim one or two depends on which sim slot you put your card .

No need to restart, both SIMs are active so you may send/receive calls on any of them.

One sim card does mot enhance nor interfere with the other. I use the second slot for a more anonymous pay as you go service when I do not want to be traced or bothered.

Advantage wise both sims can be installed and use at the same time with greater speed network wise
