T-Mobile rolls out 4G LTE CellSpot V2, 4G LTE Signal Booster Duo devices

tmobile4gltecellspotv2

Recently, T-Mobile quietly released a couple of devices meant to improve the signal that you get at home.

The 4G LTE CellSpot V2 is an updated version of the device that T-Mobile launched two years ago. This new model offers a smaller form factor, better ventilation and vertical stability, and the ability to support LTE on both Band 2 and Band 4.

T-Mobile’s 4G LTE CellSpot V2 gives you a dedicated LTE connection in your home, complete with 4G LTE voice and data. It supports up to 16 simultaneous connections (8 on 4G LTE and 8 on 3G/4G UMTS), covers an average of 3,000 square feet, and can be accessed by any T-Mobile customer within range. It does not support Band 12 LTE (700MHz).

T-Mo will loan the 4G LTE CellSpot V2 to qualified postpaid customers without a monthly fee. (There is no purchase option.) The device connects to your in-home internet connection and a GPS antenna to provide you with a cellular signal. T-Mo says that no existing in-home signal is required, but customers must be within T-Mobile’s coverage area to use this device.

When using the 4G LTE CellSpot V2, your data speeds will vary based on your internet connection, simultaneous voice and data sessions, and other factors. Any data used over the CellSpot will count against your data plan.

Also of note is that the 4G LTE CellSpot V2 supports both T-Mobile-branded devices as well as BYOD devices that support T-Mo’s network.

T-Mobile also recently began offering the 4G LTE Signal Booster Duo. This is T-Mo’s first signal booster that supports LTE Band 12 (700MHz).

The 4G LTE Signal Booster Duo will extend and improve T-Mobile’s network in your home, offering coverage of around 3,000 square feet. To get one, you’ll need to be a postpaid customer with at least one bar of 3G/4G or 4G LTE signal. After a $25 deposit, T-Mo will loan a 4G LTE Signal Booster Duo at no extra charge.

With this device, you place a window unit wherever you’ve got the strongest indoor 3G, 4G, or 4G LTE indoor signal. You then place the coverage unit wherever you need to improve your signal the most.

T-Mobile’s 4G LTE Signal Booster Duo supports 3G/4G and 4G LTE on both T-Mobile devices as well as BYOD devices. The maximum number of simultaneous connections supported with this 4G LTE Signal Booster Duo is 16 voice sessions and 4 data sessions.

It’s good to see T-Mobile offering signal booster devices to customers that need them for no extra charge. It can be frustrating when you get little to no cell service at home, and that frustration can be made worse when your carrier wants you to pay for a device to improve the signal in your home.

Have you snagged either the 4G LTE CellSpot V2 or 4G LTE Signal Booster Duo yet?

  • Given WiFi calling on T-Mobile, why would I get one of these?

    • Trevnerdio

      I actually much prefer the stable LTE signal over the sometimes flakiness of WiFi. The cell signal is often stronger than the WiFi signal as well, since it uses a lower frequency.

      • In this case it’s immaterial since what you’re actually GETTING is a device that is a WiFi Calling “repeater” and connects back OVER YOUR BROADBAND back to T-Mobile.

        In other words if your broadband link is “flaky” so will be this device.

        • enoch861

          I see the appeal of this device.
          Sometimes your router or your phone could have wifi issues so you could have situations where your wifi drops for no reason.
          With a repeater like this, you’d be connected via LTE which a lot of the time is a very stable connection. You also gain the ability to properly hand off calls so if you start a call in your house you can leave without dropping the call while when using WiFi calling the call just drops.

        • Except in this case the first one (The “Cellspot”) actually connects back over your router via broadband, so it’s going to be no better than your home WiFi.

        • enoch861

          It’s not going to be no better speed wise, but the connection will be a lot more stable and you’ll be able to properly hand off calls.

        • Uh, where ‘ya been the last few years? :-) Seriously, if you have VoLTE service on T-Mobile where you are hand-off between WiFi and cell already works in BOTH directions and has since VoLTE showed up on their network. I walk out of my house (WiFi connected calling) while on a call, get in the car and continue the conversation on the car bluetooth adapter all the time; the call falls back seamlessly to VoLTE. Ditto the other way around; come in the house while on a call and it will shift back to WiFi.

        • enoch861

          Hmm… You’re right! I just tried it and handoff definitely works pretty well.
          I’m always conscious about when I use Wifi calling so I’ve never tried handoff for a few years now.
          I guess now the use case of the cellspot for residential use isn’t exactly clear. But it’s good it still exists.

        • Brody

          I’ve had the same experience — handoff (from Wi-Fi to cellular) only fails in areas with poor coverage (3G or worse from my experience).

        • Trevnerdio

          It’s a lot better than WiFi, because it connects via Ethernet. No longer do I have to rely on the high frequency, low output power of WiFi. My broadband connection isn’t the problem, it’s the wireless router itself.

        • Matt Macaluso

          The speed tests show it!

    • Sharti24

      Wifi calling voice quality is terrible compared to a cellular call. Plus its annoying turning on and off wifi calling everytime you use it

      • Get rid of your iPhone. Seriously. So-called “HD” calling on them is horrid compared to Android devices; Apple did some seriously-bad stuff with the voice codec code they’re using in there for that mode. It’s stunningly bad compared against any Android handset.

        I’ve been using Android-based WiFi calling now for the last few years and it’s landline quality. I often do radio interviews over it, in fact, and except when there’s something going on with the Internet there’s never been an issue with voice quality.

        • Sharti24

          Lol i do have an iphone. A 6s plus to be exact! Love it!!!!!

        • Doakie

          Yeah I’m currently on a Stylo 3 Plus and my wife is using a J7 Prime. We often talk when one of us is on WiFi calling and it’s always the HD Voice quality. Crystal clear.

        • NapoPeb

          You do realise the codec is set by the network, not the handset right? Clearly not.

        • While that is true the fact is that I can tell instantly if a caller is on WiFi or VoLTE and an iPhone — because the quality blows. Same call, Android device — may as well be talking to them to a foot away from me.

          IOS’ implementation on this, and the tonal balance they use, bites. Period.

      • scruff317

        Been in South Korea for going on 2 weeks. I use the Wi-Fi calling on my S7 Edge. The usual response I get from the person I am calling is where are you? I have been told it sounds like I am calling from around the corner, not another hemisphere.

        • Sharti24

          Does that dip into your minutes or cost you anything? Free data and $.20 cent minutes if you use the cell tower correct?

        • Romdude

          It’s free if you were calling to someone in the US. 20 cent per minute for everyone else which is still way better than other carriers.

    • superg05

      exactly and your being billed for it coming out of your plan when your internet is powering it is hilarious

      • Andrew Singleton

        no, the device is free for post-paid customers. small refundable deposit if you dont lose or smash it.

        • Sharti24

          He ment you are being billed for tmobile data if you use data via the cellspot. Not for the cellspot device itself

        • Andrew Singleton

          oooh got it. get the cellspot router instead! it’s basically a free, super powerful router and then you’re just using wifi for data, calling and texting.

        • Sharti24

          Or get the signal booster so you dont need to depend on wifi

  • Sharti24

    They need to offer a single stand alone device that doesn’t require an internet connection to use.

    I see that they support the signal booster (which doesnt need a home internet connection) but if you live in a small apartment its hard to seperate the window unit and the coverage unit without them interfering

    Tmo needs to take a play from Sprints playbook and offer a device similar to their “magicbox”

    • (J²)

      They’ve had them for years, they just haven’t been refreshed or advertised. The main reason they aren’t pushed as much is because they don’t work well. That’s why T-Mobile has invested more in a solution that uses your internet connection.

      Signal boosters are good at taking a stable cellular connection and essentially extending the range of coverage it doesn’t improve the signal.

      The issue isn’t dead zones, it’s the lack of low frequency spectrum T-Mobile has had – until recently. If you are not receiving any reliable coverage anywhere indoors, this isn’t a solution for you.

      • Sharti24

        Had what for years? Im talking about they need a single stand alone device that doesnt require a wired nternet connection and doesnt use two serperate devices like the signal booster does. This would be convenient at work because no boss is gonna let you plug your Tmobile cellspot into the company’s modem lol

        They need one signal device just like the sprint “magicbox”. Then you can plug this in at your desk tucked behind your computer or in a drawer if you dont want your boss or coworkers asking “what is that”?

        • Kaulana1989

          They have a new version signal booster support band 12 700A

        • Sharti24

          Correct but it uses 2 separate devices for a connection. A window unit and a coverage unit

  • Matt

    I would love to be able to get one of these but I am a T-Mobile customer. I probably could not buy one outright.

    • Sharti24

      You cant get a free one as a lease. No option to buy at full price

    • SirStephenH

      “T-Mo will loan the 4G LTE CellSpot V2 to qualified postpaid customers without a monthly fee. (There is no purchase option.)”
      ~Article Above

    • EF

      While not covered in the article, others have mentioned the T-mobile WiFi router that works with WiFi calling prioritization. Refurbished units available for sale, even to non T-Mobile customers at Amazon.

  • John Doe

    How the hell do they not have a 4G LTE cellspot that supports all of their LTE bands?

    They can use them as small cell towers and offer customers a bill credit.

    • Sharti24

      1. I think its because they dont have nationwide 700mhz like they do with 2100 and 1900.

      2. Lol yeah right

      • John Doe

        Well they can disable those bands based on your location, actually the cellspot does not work without your location so they can easily get your location from the gps that is included and from your ip address.

        • Sharti24

          The cell spot is ment to cover a small area. Why would you need 700mhz to cover your house? 2100/1900mhz will do the job perfectly. 3000ft is a decent coverage size

        • John Doe

          I said they should act as small cell towers…passersby can already connect to it.

          Also, it is about speed the more bands available the better carrier aggregation will be and faster your connection will be. This way then can future proof it without the need to create several versions of the device.

        • Sharti24

          I “think” the cell spot is fully depended on your home wifi speed. So if you have a 10mpbs home internet plan with Att uverse, dont expect to see 150mbps with Tmobile while connected to the device. So CA would be pointless if that’s the case.

          T-Mobile is not going through the trouble of disabling 700mhz for only a few people who arent in a 700mhz area. What happens if the person lives in a 700mhz area then takes the device with them to their winter home in a non 700mhz area? Sure the “gps” would know where you’re located but it seems more of a hasssle than what its worth. The box had to pass through the fcc to be approved and the fcc wouldnt approve a device that “could” broadcast a frequency where tmobile doesn’t own spectrum in. Plus why would you want it broadcasting 700mhz if you lived in an apartment complex? Then all your neighbors could connect to it essentially slowing you down while muching off your home internet plan. (I bet tmobile would love that though)

          Im sure the next cellspot that comes out will have 600mhz built into it because they own it nationwide.

        • RJKMadison

          That is new then. They have not been able to disable bands. It will not activate in my area because they don’t have sufficient band 2.

    • SirStephenH

      The cellspots are meant to cover a small area (~3,000 square feet). Band 12 and band 71 (there is also very little hardware supporting B71 at this time) would be unnecessary overkill in this situation and would be more likely to cause interference with neighboring cells. As for band 66, T-Mobile has very little of it and it’s not one of their main bands.

  • brian mcnish

    Anyone have this yet or know how to get it? I called customer service and they told me that they don’t see anything newer available than the one i got a couple years ago.

    • Brandon Cruz

      I just called and requested the new version of the signal booster that *doesn’t* require internet. If this is the one you’re trying to get, it sounds like it’s referred to version “RS3” internally, so you may want to mention that to the rep when you call in.

  • Sharti24

    I know it says “no signal required” but if you use it in a roaming area of lets say Wyoming, will it still work properly?

  • Doakie

    As a MetroPCS customer I really wish I could get one of these.

    • Sharti24

      I don’t think it wouldnt even connect to it

      • SBacklin

        It does, I have V1 of the 4G LTE CellSpot and my friend who has Metro connects to it automatically every time.

        • Sharti24

          Thats great news that it connects.

          I wonder what would happen if they bought their own off ebay and set it up. Ive heard mixed reviews of it both working and not working properly

  • Luis Hotdaddy Vasquez

    If I have the first version of the cellspot, can I have the new one?

    • Kaulana1989

      Of course you can just request a new one

  • Good

    Ridiculous to count my data

    • Sharti24

      Then get the signal booster instead

  • ecdy_ _

    i’ve had experience with all of these devices and in my area, where the LTE signal is weak and intermittent, I like the wi-fi router best. My experience is in the Berkeley (CA) hills, where no carrier transmits a strong signal, and all are flaky – dropouts, no access, etc. occur at least 80% of the time. I first tried the LTE signal booster, which was useless because it’s really only that–it boosts the signal if you have one in the first place. Then, the LTE CellSpot, that connected to my own WiFI router over an EtherNet cable. That worked very well, although of course was limited in speed to that of my internet connection. However, the last possibility, the TMo WiFi router used for WiFi calling, is better than the combination of CellSpot + ordinary router, because, while anyone with a TMo account within range can access the CellSpot and use your bandwidth, with WiFi calling you have to have to set up with the router password (only once) in order to make calls. With the CellSpot, anyone within range can use your phone bandwidth.

    Of course, the CellSpot does not require a phone equipped for WiFi calling. Nevertheless, I like the added security of WiFi calling, and most recent TMo phones have WiFi calling capability. I haven’t found any major difference in call quality using WiFi calling.

    Incidentally, the TMo router is an ordinary router supposedly optimized for TMo WiFi calling. I don’t know what the optimization is, but it’s a good and up-to-date router and TMo will just lend it to you.

    • Sharti24

      How fast is your home isp and what speeds were you getting when your phone was connected via cellspot

      • ecdy_ _

        My ISP was at 10, the vendor was about the same as wifi calling through the router, maybe up to 8 or 9 depending on signal strength.

  • mikeZo6

    well Tmo tried to send me new signal boost with band12 3 times and the kept saying its the newest one but it NOT same as my RS3 been using for over a year now, Tmo CEO office said the RS3 has band12 in it but i clearly states band 2 and 4 only !
    Even Johns L ( CEO ) office is clueless

  • steveb944

    Hopefully the booster works much better now, I had the original and it was worthless. Ended up getting their router and it’s worlds better.

  • the martian ambassador

    If other T-Mobile customers in the area can access your cellspot, wouldn’t their data usage be counted against your line ?

    • marque2

      No because data usage is computed based on the phone account. You just are providing an LTE antenna.

      • Travis Peregrin

        That’s true as far as your T-Mobile line goes, however if your internet connection is metered, a neighbor could dip into your monthly data allowance. The worst-case would be living in an apartment complex, having a metered internet connection, and having a neighbor with T-Mobile One basically use your LTE Cellspot around the clock to download torrents. In a typical residential neighborhood, however, this scenario is much less likely and I find I swap from FemtoCell to Macrocell about 10 feet off the edge of my property line.

  • EF

    NOTE: I have the current LTE booster, and it has worked to send what is 1-2 bar LTE at our second floor transmitter location down to the basement receiver where we normally would not have ANY cell signal. But after reading this, I decided I might want to upgrade my old 600N WiFi router to the AC-1900 T-mobile ASUS WiFi router which looks pretty sweet, and all our phones now have WiFi calling. Seems that you can only have one device at a time through T-Mobile’s lease program and I still like having the LTE booster just in case our internet connection goes out. But these routers are actually on sale (refurbished) at Amazon.com for about $60, which is not a bad price for a very highly rated WiFi router, with bonus T-mobile call prioritization over WiFi. Just ordered one!

  • Marcus Rose

    We went from the 1.0 to the new 2.0 Leaps & Bounds difference. The added capacity for 8 lines to LTE and 8 lines to 3G/4G helped with others piggybacking on it. It rarely flashes now and connectivity is outstanding. No more do I have to walk around the house to get the best signal…I can be wherever and it works!

    Thank Goodness too…I didn’t know if we could stay with T-mobile much longer because of this exact issue…but its been resolved.
