The Signal Booster DUO (Band 12) is made of UNOBTANIUM

I contacted T-Force who did some research and discovered that the Booster Duo that covers Band 12 and announced in a massive press release has been 'out-of-stock" since late December with no restocking date.  Looks like this unit is made of UNOBTANIUM.  I don't understand how T-Mobile can still post a web page with the details of this unit if they have no intention of making them available.  I REPEAT, PER THE PERSON I SPOKE TO AT T-FORCE, THERE HAS BEEN NO UNIT THROUGHOUT THE COMPANY IN STOCK SINCE DECEMBER.  Anyone have an idea of a way to contact the right person at T-Mobile who would honestly explain T-Mobile's future strategy on whether they will actually make these units available.  Going through the normal customer service channels just winds up with an out-of-stock answer - no explanation of why a newly announced offering last November stocked very few units in December and hasn't restocked any in the past FOUR months.

  • @duhmel​, I understand you're frustrated with getting the run around and we want nothing more than to help out. I'm sending you a private message within the next few minutes. You can check your inbox aquí.

  • Can you check my reply below...I finally believe I got the correct duo booster. I download the Cel Fi app and it shows the 700 mhz being found, but not boosting?

    Your experience is very similar to mine.   Using Field Test on my phone *3001#12345#* I found that I had LTE coverage in my house is between -110 and -120 that changes between Band 2, 4 and 12 depending on the time of day.  4G coverage is usually pretty good.  The Cel-Fi usually locks to a strong Band 2 signal that is listed by the Cel-Fi app as T-mobile 3G CDMA and is always boosted.  Sometimes the booster will lock to a Band 4 LTE signal if that is the strongest one near the Window unit - otherwise it will stay lock to the 3G/4G signal and not boost LTE.  The Band 2 3G/4G signal is always boosted.

    I sent the log into Cef-fi and started exchanging emails and yesterday spent over a hour with tech support (Evelin) on the phone (858-485-9442, Option 1). I discovered a few things.  She claimed that the strong Band 2 signal that was being boosted that is labeled as 3G CDMA could actually be a 4G T-Mobile signal.  Also - even though the new unit can boost Band 12, T-Mobile has decided to set the software to not boost B12 signals if there is any B2 or B4 signal available.  So even if B12 is the strongest signal received, the unit is set up to not boost it if a weak B2 or B4 signal is present.  However, the weak B2 or B4 signal may be too weak to be locked on by the booster and will not be boosted so the net result is that no LTE signal is boosted.  Evelin told me that Cel-Fi can send a signal to the Booster to allow the B12 LTE to be boosted but that should be the last resort if you are not getting any other band coverage,  I am fiddling on disabling LTE on my phone at home to get it to lock to 4G and see how that works first or to use Wi-Fi calling as a backup before asking for the software change.  I would suggest that you do the Field Test check to see what Bands are in your home and then give Evelin a call.  She is very patient and helpful.  Looks like you have a similar situation as I have.  Let me know how it works out.

    Hi!! I am experiencing the same run around regarding the band 12 Signal Booster duo. They want to send out the rs3 to me. But I am pretty sure that is the old model. Am I correct in understanding this? How did you contact the Senior management. Did you just tweet them and message them telling them all of the problems that you are having with getting the right one? I hope you can help me. Gracias.

  • Hello, I'm having the same issue as you, would you mind forwarding me the info to use band 12?

    I found this post in a quest to find the elusive T-Mobile band 12 signal booster. Here it is almost a year since the last post, and still, T-Mobile support doesn't seem to be aware of the existence of the booster and it is still unobtainable. I'm on my third booster, still the same as the original booster. None will support Band 12. About all I can receive in my area are bands 12 and 71.

    THIS IS THE STUPIDEST EXCUSE I HAVE HEARD IN THE TWO MONTHS THAT I HAVE

    BEEN TRYING. FANFARE LAST NOVEMBER - WE HAVE A NEW UNIT THAT COVERS BAND

    12. NOW I AM EXPECTED TO BELIEVE THAT THERE IS NO WAY TO SPECIFICALLY

    ORDER SUCH A UNIT. NO COMPANY CAN BE THAT STUPID, ONLY PEOPLE WORKING AT

    SUCH A COMPANY WOULD BE THAT STUPID, I HAVE EMAIL YOUR CEO LETTING HIM

    KNOW ABOUT THE RUNAROUND I HAVE BEEN GOING THROUGH AND HAVE LET HIM KNOW

    THAT YOU AND NIC HAVE GIVEN ME THIS ABSURD REASON.

    Today is 10/22/2022 and the extreme incompetence and ignorance displayed by the corporate decision makers with their policies and dysfunctional methods of training and supplying information to the call center staff and customers, is still alive and well unfortunately. Various reps I have spoken with over the past week have no clue there are 2 Cell Spots, one that is 1 unit and works off Wifi, and another that is 2 units, called the Personal CellSpot 4G LTE Signal Booster, and works off the tower signal by placing the antenna unit in the window and the receiving unit at the other end of the home.

    The model # for the 2 unit device from the side of the box is NXT CELFI-D32-21266 with a date of 01/07/19.  I had to dig the box out of a plastic container in the shed so I could research what bands it uses. I had to beg repeatedly for this second unit to use after hurricanes.

    I also have the other unit that works off Wifi which I normally use since we are in a rural area. But Hurricane Ian just went through here on 9/28/22 and the cable/landline phone and internet infrastructure was decimated. Centurylink told NBC2 here in FT. Myers Fl that the projected date for complete restoral of the internet and landlines could be the end of February, 4 months from now. So I am researching outdoor antennas so I don't have the indoor antenna unit of the Personal CellSpot D32 hanging outside{did this 3 days ago} on a PVC pipe/pole, inside a metal base pole, under an umbrella, on top of my 6 foot above grade septic hill, the only place I can get a signal on my 5 acres on a regular basis, pre or post hurricane without the Wifi CellSpot. The Personal CellSpot D32 window antenna unit does not work well inside my metal mobile.

    Hopefully the $1000 plus Cel-Fi GO X 100dB booster with the Long Ranger Antenna will provide some decent service since I am not interested in it taking 8 minutes to log into my bank and then have a bunch of empty rectangles where the accounts are suppose to be, never mind all the can’t load the page errors, or having to wait until 1 a.m. through 5 a.m. to be able to have usable internet access with the Personal Cellspot indoor antenna.

    I have been using the internet through a hot spot in my Samsung S8+ TMobile Tablet that is no longer fully functional, can't make calls and texts with tablet through my S22+ phone, and can't add blue tooth devices because Samsung turned off the features until I signed their new privacy policy they issued the day, 9/2/22, they notified us about their Breach, I finally accepted the policy some days ago after talking to a few lawyers and the features still don't work. Added this info in case others are having the same Privacy Policy blackmail issues with "calls and texts on other devices".

    The worst part of Hurricane Ian has been dealing with humans.

    T-Mobile has by far the worst customer service I’ve been on the phone with them for 2 hours it’s this is ridiculous.
