if I purchase 2 systems for a side by side duplex. will they interfere with each other? Does it come with a sim card, if so how is it activated?

I don't know for sure if it will interfere, though I don't think so. It does not come with a sim card, you have to purchase and activate one with your mobile carrier then simply insert it.

No you have to buy the duplex stuff to install it, it's about $ 90.00 on EBay. I hope my answer did help you in your decision making.

The duplex function is automatic. This link from HP's site should point you in the right direction if you need: http://bit.ly/1iHUJs6

In the Settings Menu you have the option to activate either SIM 1 or SIM 2, the SIM activated will be the SIM (phone number) you'll use until you choose to activate the other one. Even though it can hold 2 SIM cards at once you don't need two, if you have 1 ISM card you can still use this phone.

It can use 2 sim cards at once. It works fine with just one though. It is supposed to be able to work worldwide but we haven't tried it yet.

Yes. That's absolutely right. Currently, I utilize two sim cards from two different providers at the same time. Both sims (with their respective numbers) are active at the same time and I have had no problems making or receiving calls from either.

No it doesn't need two sim card to work, you can install one or two sim, if you have two diferents cell phone number

yes. it installs with duplex enabled by default. I had to turn it off after installation on our units, since we don't utilize duplex

It is a dual sim so both sim can be in at the same time in different slots. Dial the number u are calling and it would ask which sim, sim 1 or sim 2. Select your required sim and that is it.

The one I bought was a replacement for a friend who had one go bad. I switched his sim card over from the one he already had. And it worked fine. I imagine you would have to obtain an activated sim card from your provider if you do not already have one. Sorry that is all I know about it.

No. There is no interference with mine. NOTE, however, that the GPS location described in the specs does NOT work. The manufacturer said they couldn't afford to include it at this price but they put it in the specs and send a GPS antenna with it. My antenna is installed and that does not cause any interference with the radio either.

These intercoms require that both buildings' electrical systems be tied together. My recommendation is to use walkie-talkies. That is the solution I chose for a similar problem.

Yes. Simultaneously. You can activate two in the same region for different numbers. Or if you travel you can have one domestic card and the other dedicated to an international provider where you travel. Pretty nifty!

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.

Not unless you also have the dupleximg module. But, they are expensive and hard to find.

No, you just need one. :) It has a spot for two SIM cards but you only need one. I was confused about that as well.

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.
