Does it need a land line. I only have an AT&T cellular

No land line is used at all. This product brings in the cellular signal outside and replicates it inside and vice versa.

You do not need a landline, just a cell tower signal. Read the info on this DB Pro...it says it works with most cell services I think. My service is Verizon.
648437
No. Just a signal from AT&T; where you install the antenna and an electrical outlet where you install the amplifier.
648438
No, it is not connected to a land line at all. It is meant to boost the cellular signal from outside to inside the house.
648439
No, it doesn't. The way it works is that it provides antenna for better reception and then re-broadcasts to your phone. So in short, it's a signal booster, not an alternate signal path.

In a word... Yes. Works great with a land line. The best thing about this phone is its ability to use your landline and connect to Bluetooth on your cell at the same time.

I am not sure how that would work exactly, but the only smart phone this works with is the iPhone 4S and with an adaptor the iPhone 5. I never tired it without the land line but it should work because I can call and receive calls on my iPhone.

This and the base unit are single line phones - the product description on Amazon clearly states this works with single line phones. If you meant to ask whether you can use the land line as well as one or two additional cell phone numbers with it, yes.

I think it still requires a SIM card from AT&T.; I am using my phone with StraightTalk and I had to put a SIM in it, but once the card was in it worked great! (Note: since this is an unlocked phone, you may have to enter the appropriate APNs (access point names) for your service.

Yes you need a landline in order for the alarm to be able to call you. However just to soun an alarm it wll work. If you don't have a landline I would also get the outdoor alarm. There could be a new adapter out there somewhere to plug a landline into a cell but I don't know. Let me know if so! Mark

Thanks, I have Internet via AT & T, I would think it will work, I do not have a land line phone?

No. If you connect your cell phone through Bluetooth, you can use your cellular plan to talk. No need for a landline.

You need a smarter phone. I am sure that Amazon should have a product for your landline phone.

Yes of course it's works without land line, but you won't receive calls to your land line on this device in this case

I do not have an active landline. i have a dsl connection and a filter on an old phone jack that i left from when it was active. Not sure if it is necessary.

I only use land line. But the product instructions manual said that you can setup with mobile phone. I have never tried to use the mobile phone feature.

It requires a cell phone plan. You have to put a SIM card in it. I was able to add it to my T-Mobile family plan for $10 a month. This was far cheaper than a land line option for me, which is why I went with it.

Yes. A land line is not necessary for this product to work, but the sub-stations must be properly wired for complete use.

No. It works without the landline. You can link the line with 2 cell phones. Works just like having a landline. Great sound quality. Definitely happy with my purchase.

You do NOT need a land line to use this system. We don't have a land line. You will see a message on the handsets (on the bottom of the display) that reads "Check tel line." Just ignore that. You can connect 2 blue-tooth cell phones.
