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

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.

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.

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.

Yeah so T-mobile doesn't actually have 4G. It's just a rebranded fancy 3G that they call '4G LTE', meaning Long term evolution. The 3G CDMA was most likely either verizon or sprint.

Hi Amanda - I am having the exact same experience where I need to get a band 12 Duo+ per the manufacturer given the location of my home, but no one at T-Mobile support knows what I am talking about or how to put in an order for that specific band 12 Duo+ device. Can you please help me?

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.

Its crazy that there are so many folks having the exact same issue getting these magical devices... T-mobile!!! Don't advertise something you can't deliver on! I have been through 4 or 5 of the old devices sending them back as soon as I open the box... PLEASE! Get your system updated, or stop lying with your coverage maps...

Hi I also need signal booster duo + Model D32-21266 i have already recieved 3 of the rs3 regular duo model and they did not work because of band 12 is there any to get Model D32-21266

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

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.

Marty...

You are the only one to get the bottom of this issue that I know of; so glad I found your thread. You are correct, all my issues are the same pretty much. When I first saw your message I did contact Cel-Fi, and it was actually Evelin that contacted me. I had sent her a log from the Cel-Fi app and it did show I was getting Band 12 (but not boosted) but also a week band 4 signal but so week it couldn't be boosted. Long story short, Evelin told me that the band 12 wasn't repeating so she had her tech person send me the software change info to only allow the coverage unit to use band 12 only. Once I use that information and hooked up my laptop up to the Cel-Fi coverage unit, I reset the software to only use band 12. That's all it took and it worked great, got full coverage in house now. I wish the T-mobile tech personal were aware of this w/out all of us going through all this trouble. Did you get your issue resolve? If you need the info she sent me regarding setting the unit to use band 12 only, just let me know, or you can probably ask her and she will do it (if you haven't already). Thanks again for getting back with me in this thread. Let me know you if it works out for you as well.
