- CELL2JACK - Cellphone to Home Phone Adapter, Make and Receive Cell Phone Call on Your landline Phone Free - Cell Phone to Landline Dock - Cell to Landline Converter

The Cell2Jack works really well and does exactly what I needed it to do. Setup was straightforward, and I love that it has command codes available in case you need to troubleshoot or adjust settings. That feature alone makes it feel more reliable and user-friendly. The call sound quality is pretty decent — voices come through clearly, and I haven’t had issues with distortion or major delays. I can leave it plugged in without any problems, and it stays consistent. One thing I really appreciate is that it’s not limited to standard phone calls. It also works with audio calls from social media and messaging apps like Instagram, Snapchat, Facebook Messenger, TextNow, TextFree, and others. That flexibility makes it much more useful than I expected. Overall, it’s a solid device that does what it promises and adds convenience if you’re looking to connect your calls through another system.

I could not be happier! I got this to move over our expensive landline service to a cheaper mobile one, and this was the perfect solution. It’s everything I hoped for and more. Very easy set up, quality sound, and the cord being short is a non issue since telephone lines are typically long. It even works with a hub that you can connect multiple landline phones to! Every phone rings. Initially, there were loud static sounds, but it resolved after reconnecting the telephone line to both the phone and cell2jack adapter. My set up is: iPhone 7 with homepage Shortcuts configured to dial a contact with their photo set as the “app” icon. This is a good solution for seniors, kids, or anyone illiterate.

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!

Works. Setup is pretty straightforward, just follow the instructions. Works well for one old phone at a time. You're cell phone works as usual. If you answer on your cell you wont hear anything as all the audio is switched to your phone line. You can answer on your cell or your old phone and talk on the old phone. I have it connected to my house line so I can plug in extra phones like I used to have it with my land line. We used to have 'conference calls' which different people on each hand-held phone. I can pick up on either phone but if I pick up the extension, and then pick up the phone closest to the cell phone, it will cut off the extension. If I pick up the phone closest to the cell, then the extension, I can hear on both and use it like I used to. I noticed that the quality of my extension phone is much better than the phone next to the cell. Oh well. There is some noise when using both old line phones at the same time and it is a bit hard to hear on one of them (the cheaper one) - wish there was a volume control to get more volume. When using any one phone, it is fine. The background noise is not really noticeable on either of my phones although my extension phone's background noise is nonexistent and the volume is higher. It is a better phone though, one from an office. I like it and am glad I got a good working cell2jack so I can pick up my phone in the other room instead of running where the cell phone is. Would definitely buy again. Edit after a couple of months: Not always consistent. Sometimes just gives silence when picking up a call and the other person gets silence also - no contact made. Recently, did not trigger the answering machine but went to voicemail on the cell phone so did not know anyone called. Also, most times now, does not connect call when pick up extension. Not reliably working.

Wow works so well, I love it. I love being able to use old school phones and just have it connected to my mobile. When I’m at home I can leave my mobile on silent in another room and know my rotary phone will ring if someone calls. Great idea

I don’t often write reviews but this product really works. Setup was effortless (using old iPhone and Panasonic cordless phone with 2 base stations). Call quality is acceptable, what one would expect from earlier generations of Bluetooth earpieces - relatively clear but not exceptional. There is a slight lag before the recipient’s phone rings when calling out but less so when calling in. Overall, very much value for money.

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.

Sehr gut

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.
