Parents looking for less screens for your kids. THIS.IS.IT
This is a fun and cool way to tech your children how to have phone etiquette if that's the right word. We have a toddler they love to talk to Grandma Aunts ect.. but the screen is a DISTRACTION. This was an attempt to see if my toddler would stop trying to touch the screen or scroll and see of they actually have the ability to talk on the phone. When it was just my cell phone, my toddler would sit in silence as Auntie or whomever would talk and then just try and look at the screen. I got this and it's been really fun. They know when the phone rings it's someone calling,and they actually talk and have well a toddler jibberish conversation but they found it fun. It's the first time I have seen my 3 yr old actually try and converse on the phone to someone. I am using it to teach important phone numbers and dialing out as well as just simple phone etiquette when it's appropriate to answer a phone around meals, and use it ect.. its a great tool. So to me as a parent this is a win to me. I needed to lessen my screen time. I now have with this being hooked up in our home. My child sees that I dial out (you don't have to you could just use your cell phone but I'm trying to lead by example) it's one less techy screen distraction in our home and I believe it's making my child a better communicator. I am going to attempt to find a Jack splitter to see if I can hook up 2 different types of landlines and still they all ring and work ect.. Will update once I do. I viewed the cost as much as a typical Bluetooth so it seemed reasonable, I think it is a good value. You still may have to purchased a landline (we goodwilled ours) and a RJ511 phone cable. It's durable and not cheap feeling in weight and how it was packaged and put together. Fast to put together once you have all your cords, and yes it's corded tech so you have to organize that but the appearance isn't ugly or gaudy, it's just a small white box the size of an average palm I would say. I 100% recommend to anyone searching for a tool to lessen screen time or teach phone use.

Great Little Device!
I will start out this review by saying I do still have landline telephone service at my house. But recently I took possession of an old landline telephone that belonged to a family member, and wanted a way to use it via Bluetooth with my smartphone. The cell2jack does exactly what I need it to do. The phone I tested this with was a 1970s touch tone desk phone (I do NOT currently own any rotary dial phones with modular (RJ11) jacks, so while cell2jack says that this WILL work with those phones, I don't have a way to test that (yet)). Pairing is simple: just plug the USB cable (which is admitting short) into a wall adapter like the one you use with your smartphone (they do NOT include one in the box... you have to supply your own, which isn't a big deal, and while the included USB cable is short, you can swap it out for ANY USB cable if you need a longer one), plug your RJ11 cord into both your phone and the cell2jack (also not included, but that's expected), and then take your landline phone off-gook, and dial #*# (a voice prompt will tell you to pair it to use it). Then just select it within your smartphone's Bluetooth devices, and connect to it. The cell2jack essentially turns your landline phone into a Bluetooth headset for your smartphone. One thing I will say about the cell2jack is that I believe there is supposed to be a dial tone emitted from the landline phone connected to it (just as if you were using a regular landline), but I got no dial tone when I picked up the receiver. However, the touch tones still worked, and the calls were patched through to my smartphone immediately. This may cause confusion for some. Receiving calls works well, and the mechanical bell ringer on my vintage landline phone started ringing at the same time my smartphone did. In both cases (making and receiving calls), when I hung up the handset of my vintage landline phone, the cell2jack disconnected and ended the call on my smartphone almost immediately, which is great. I haven't yet connected the cell2jack to a landline phone with built-in Caller ID, so I'm not sure if the CID information from my smartphone would pass through to a connected landline (I will be trying this in the near future). You can apparently also hook the cell2jack directly to an RJ11 telephone jack in your house, and ALL landline phones in your house connected to other RJ11 jacks will work together as if you had landline service. This is also something I have not yet tried, and don't have any intention to, as I have landline service as well. Another feature I haven't tried yet and would like to try is the built in pass-thru for a smartphone's voice assistant (i.e. Siri or Google Gemini). I will have to try that soon as well. Finally, I love how small the device is. I'd assume that, if you had enough space inside the casing of your landline phone, you could put the cell2jack right inside of it and hide it, although sitting behind or right next to your landline, it still looks good. Whether you're a vintage telephone collector, or just want to keep your landline phones hooked up after you disconnect your landline service, the cell2jack delivers. Sure there are more expensive devices like this out there, but the cell2jack delivers on what you'd expect one to do for a great price. Highly recommended!

Perfect It’s great sounds authentic
First of all I almost did not buy this because of the reviews. I am please with my purchase. I bought a phone from Amazon to go with it. I just got it today about 2 hours ago and I slammed the phone down on my daughter 3 times already. So in the reviews people spoke about the static. Ok so yes it has some air that a cell phone does not. That’s is normal if you ever had a real landline phone back in the day you know it sounds just like this. My calls were clear and I am very pleased with this purchase. I let the phone ring and I listened to The dial tone over and over. Memories this was the best purchase for me this year. This is the closest to an authentic phone line you are going to get. It comes with instructions but my cell phone paired automatically no issues with cell2jack. I love it you will love it. Oh and ot has an old school ringer Í promise of you are in doubt do not be. Put it in the cart right now and do not take it out buy it. You will love this.

Works and allows me to avoid my Cell Phone when home
4.5, I like it. Using with AT&T Corded Home Phone ( https://www.amazon.com/dp/B09R1QDLH6?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 ). It works, the Phone reliably receives and makes calls from my Cell Phone. Easy to set up and pair; when I get home, I can put my Cell Phone out of reach. I got these two items to help reduce my in-home smartphone usage. I don't know if it's the AT&T Corded Home Phone or the CELL2JACK causing this, but, the volume of incoming calls is low and there is a constant buzzy humming--I saw in the CELL2JACK directions that this can be caused by the power adapter used, so idk. Overall, I am thrilled with the fact that this WORKS for what I wanted it for. CELL2JACK + AT&T Corded Home Phone together costed less than bluetooth-installed Phone receivers, so I would recommend this combination to someone interested in using a Home Phone as a Cell Phone receiver.

It’s a perfect solution for anyone looking to maintain a landline-like setup without incurring monthly fees. The audio quality is excellent, and the Panasonic handsets perform as well as they did when I first purchased them.Why It’s a Must-HaveCost-Effectiveness: For a one-time payment, I’ve revived my home phone system and connected it to Google Voice, making calls essentially free.Reliability: As a backup to our smartphones, the home phone setup ensures communication continuity, even if cell service is disrupted.Ease of Use: No technical expertise needed—just plug, pair, and play.Final ThoughtsThe CELL2JACK box is a brilliant device that bridges the gap between traditional home phones and modern mobile technology. Combined with Google Voice and a spare Android phone, it’s a fantastic way to create a reliable and cost-free communication setup. Highly recommended for anyone looking to revive an old home phone system or add redundancy to their mobile devices!

GREAT PRODUCT
This is such an Awesome product. It works great with my rotary dial phone 53 year old phone. Everything worked great at first receiver volume was low I couldn't hear anyone. I emailed customer service and they answered in a couple of hours and sent me a settings adjustment and it works great. If you have a old rotary dial phone and you like to use it get this product. The Grandkids love this rotary dial phone. I would send a picture but every time I click on add photo it kicks me off this page. Get this you won't be disappointed..

It Does What It Says But A Couple Issues
Very easy set up and does exactly what is advertised, but there are a couple of issues that prevent me from giving the device a higher rating. One is it's always in Bluetooth pairing mode. That's not an issue if you're just using it around your house, but if someone has their cellphone nearby in pairing mode, they may either accidentally or intentionally pair it to your Cell2Jack. While not a security issue because that allows you to dial using the other person's cellphone (not the other way around) you may need to re-pair it to your device afterward. The second issue is the voice audio quality. While acceptable, you will not experience the same audio quality using your cellphone directly or when you use a desk telephone connected to a landline. I did download a firmware update that slightly improved the quality. To do this, you download a small file from their website to a PC. Initially my PC didn't find the device when I plugged it into a USB port. I used two different PCs and different USB ports. I tried the next day and it worked. I don't know what it wouldn't work initially. There are also some settings you can change in your device from this software. You can experiment to see what settings are best for you. The Cell2Jack needs to be plugged into an external USB power source to work. A USB power adapter, like you get with most cellphones should work. I've been able to use this device with a rechargeable USB power bank with no problems. That should work if you're not near a power outlet. I'm using a 10,000mAH power adapter. I can't vouch if smaller ones may have issues.

Making cell phones easy for the senior citizens!
My dad is beyond thrilled with this setup!! I cannot praise it enough! It’s very small but sets up easy. It doesn’t like to stay plugged in so that’s a problem. The landline phone doesn’t work if this device isn’t plugged in. Once we learned to check for the red light we had better success.

Funciona
El único problema que he detectado es que no permite cortar la llamada entrante no iniciada desde el teléfono no celular. Es un problema menor. Respecto al alcance del Bluetooth para que el celular se conecte al dispositivo indican que debe estar al lado uno del otro pero en mi caso he probado a más de 10 metros en habitaciones diferentes y seguía funcionando. Por lo demás funciona según lo que prometen.

Perfect
Wonderful! Once purchasing the right landline with loud volume the set up was easy. Connects with a mobile and has adjustable settings. Highly recommend for young kids and family. Works as a family mobile that can be taken when going out, then put away and used as normal landline at home ✔️✔️

very good but dialing function does not work in my country
the device provide an amazing and swift integration between mobile phone and old rotary phones (or any other dial phones). no programing is required and ringing quality is good, I used it with socotel 63, worked like a charm. however I cannot use it for dialing. after referring back the problem to Cell2jack support team, they confirmed that in this stage their support and focus is on US market and they are adopting their dialing conventions. currently I am not using it awaiting any further updates to add a leading zero dialing function.

Compatible avec le câblage existant.
Très facile à installer. S'adapte à tout le filage existant si aucun fournisseur ne l'utilise, alors le transfer des appels est fait sur tous les téléphones connectés.
