Can't any old cell phone, even without a sim card, call 911?

Yes. The selling point here is the shelf life of the battery and the price, not the ability to call 911.

Unfortunatly, Cell phone contractors do not use SIM cards for their contract phones. It is really annoying

I had the same phone, CDMA and I did not use a sim card. It only has a spot for the memory card.

I do not think you can make make a call without the phone. That would be like trying to make a land line phone call by plugin in a headset into a wall phone jack.

This unit only dials 911. Other, more expensive models can be programmed to dial multiple numbers.

you mean "From cell phone"? what ever it is, I believe this model need a land line to work.

I bought mine in a straight talk box, but it works off Verizon towers so I don't think it used a sim card.

You can find the information on the manufacturer's web site (http://blog.obihai.com/2011/11/calling-911-with-obi-devices.html). It is on Obihai.com

You don't *need* to use the phone feature. It's optional. But it does need a landline. Cell phones will not work.

The phone has nothing to do with life alert. You just need a land line, or VOIP.

Alas! That is the system's sole deficiency. It will dial only 911. I utilize a new system, made by V-Tech, that gives you a couple options. The new system has a pair of programmable buttons on the back side. Plus, the pendant responds to a handful of voice commands. And, you can answer the landline from the pendant.

You need the base phone in order for this system to work. It does have call waiting.

No, As the US Cellular rep. told me that the phones that are 4g lte need sim cards. So an older model phone does not require them. But you still need to have it activated and linked to your account by US Cellular.

Believe you can assign 911 to a specific number key following "Speed Dial" instructions in manual. Then pressing that number key and holding it will dial 911.

I have a local regular (mini?) sim card in there now, but it has slots for two sim cards. I'm also using a thumb drive that I load 'time' onto for my internet here in the Philippines. The thumb drive uses a sim card as well, it encases a micro sim card, which I have to insert into the cellphone to receive the load, so long story short, I guess it takes both. Hope that wasn't too confusing!

you cannot directly connect a sim card. You have to connect your phone via usb cable to it.

You have to be able to push the button which dials directly to 911. They can communicate with you through the call button. Haven't convinced my mother it should be hanging around her neck & not in her pocket, A key is hidden outside. Good neighbors are also an asset!
