About the device

The 4G LTE CellSpot V2 delivers a strong, reliable wireless 4G LTE signal for customers with or without an indoor cellular signal on compatible 3G, 4G and LTE devices for up to 16 callers at one time anywhere a customer has broadband Internet and T-Mobile wireless spectrum.


Firmware Version
  • BSR-17.02.32.a.10.qcom_p.sig0
  • Only one coverage device is allowed per coverage use address.
  • While multiple devices can be in the same general area at different addresses, they do not work together (such as handing off between devices).
  • Only one MSISDN can be associated with the mini tower at any given time.
  • Device is not available to prepaid customers.
  • Provides a dedicated LTE connection in home or small office.
  • Delivers un-congested network capacity and improved 3G/4G UMTS and 4G LTE voice and data performance.
  • Supports up to 16 simultaneous users (8 on 4G LTE and 8 on 3G/4G UMTS).
  • Any T-Mobile customer within range can access this connection and it cannot be blocked.
  • Covers an average of 3,000 square feet.
  • No existing in-home signal is required but customers must be within the T-Mobile coverage area.
  • No complicated wiring is needed.
  • Plug and play in the home or office.
  • Connect to home high-speed Internet and then connect the GPS antenna to the CellSpot.
Supported technologies
  • Supports most 3G/4G UMTS/LTE handsets.
  • Supports both T-Mobile branded handsets and other carriers’ handsets compatible with TMO network.
  • Only T-Mobile customers can use the mini tower.
  • The mini tower only supports the following bands & technologies, others are not supported:
    • Band 4 LTE (2100 MHz)
    • Band 2 UMTS/WCDMA/HSPA (1900 MHz)
  • If VoLTE is turned off, only the voice service defaults to UMTS.
No additional cost
  • T-Mobile loans the mini tower to qualified postpaid customers without a monthly charge. There is no full price purchase option.
  • Upon T-Mobile service cancellation, the customer must return the mini tower to T-Mobile via the provided prepaid shipping label.
  • A non-return fee is applied if the CellSpot is not returned.

Technical requirements

  • Wired high-speed Internet is required; Satellite Internet is not supported.

  • Below are the minimum speeds needed to support the CellSpot:
    • Ping / latency: 200 ms (or less)
    • Upload: 0.5 Mbps (or more)
    • Download: 2 Mbps (or more)
    • Bridge mode: enabled
    • UDP ports: 123, 500, and 4500 opened
  • Supports 3G/4G UMTS and 4G LTE-capable handsets.
  • T-Mobile branded or gray market devices compatible with TMO network.
  • Must be installed in a location where T-Mobile offers service, owns licensed spectrum and has a local E911 relationship.
  • Only one coverage device is allowed per coverage use address.
  • Only one MSISDN can be associated with the mini tower at any given time.


Cancellation impacts

  • The 4G LTE CellSpot V2 works provided the:
    • MSISDN associated to the CellSpot is not canceled.
    • BAN status is not canceled.
  • To avoid the 4G LTE CellSpot V2 from deactivating, it must be moved to a different line on the same account before the associated MSISDN is canceled.
    • It cannot be moved to another account.
    • BAN to BAN moves and transactions require the mini tower be returned and a new one ordered.
  • When a MSISDN associated with the CellSpot is canceled, the CellSpot is immediately deactivated. It cannot be reactivated and must be returned.
  • Reactivating a canceled MSISDN (that was previously associated to the mini tower) will not reactive the CellSpot. A new coverage device order for a CellSpot must be placed if the customer wishes to resume that service.




Can I use multiple 4G LTE CellSpot V2s to cover larger buildings?

Multiple CellSpots can be deployed in the same general area; however, deploying mini-towers in high T-Mobile traffic area could lead to call setup failure when the device is out of capacity. In this scenario, the devices will not interfere with one another, but they will not work together. For example, an active call will not hand off from CellSpot to another. Therefore, multiple devices should not be in close proximity or used as a single solution to address coverage issues in large buildings.


Can I move my 4G LTE CellSpot V2 and use it in another location?

You can use it in a location within our operating areas and where we have an established relationship with local public safety answering points to support 911 services. Be sure to update your 911 address with us before you set up the 4G LTE CellSpot V2 at the new location.


Are my voice and data calls made through 4G LTE CellSpot V2 secure?

Yes, all voice and data calls made through the T-Mobile 4G LTE CellSpot V2 are encrypted for security.


What data speeds can I expect from 4G LTE CellSpot V2?

On the 4G LTE CellSpot V2, we have seen up to 60 Mbps downlink and up to 20 Mbps uplink, but data speed will vary based on the Internet connection, device, and simultaneous voice and data sessions.


Is there a separate pricing plan for T-Mobile 4G LTE CellSpot V2?

No. CellSpot customers use their existing service plan with T-Mobile, meaning data used over the CellSpot counts against your data plan.To access data without it counting against your plan, use Wi-Fi.


If I start a call on the 4G LTE CellSpot V2 and move to the T-Mobile network, will the call drop?

Calls originating from the 4G LTE CellSpot V2 automatically try to hand over to T-Mobile network if a strong network signal is available to transfer to. The hand-off is not guaranteed due to network availability and coverage levels.


If I start a call on the T-Mobile network and move to the 4G LTE CellSpot V2, will the call drop?

Calls initiated on the T-Mobile network are not automatically handed over to the 4G LTE CellSpot V2 even if within the coverage area. Once the active call is ended, the phone should automatically detect and connect to the CellSpot.


Can I have a 4G LTE CellSpot V2 and a signal booster at the same address?

No. Both products perform a similar function and are not compatible with each other.


Will the 4G LTE CellSpot V2 interfere with my Wi-Fi CellSpot Router?

No. The Wi-Fi CellSpot Router operates at the frequencies of 2.4GHz or 5GHz. The T-Mobile 4G LTE CellSpot V2 operates at the 1900MHz and 2100MHz frequencies. At this time, T-Mobile is no longer offering the Wi-Fi CellSpot Router but will still support customers who have one.


Can I purchase a 4G LTE CellSpot V2 from another company or website and then use that device for an in-home coverage solution for my T-Mobile devices?

No. CellSpot devices will not work if purchased from third party companies or websites. CellSpot devices are pre-provisioned by us at the time of order. Devices from other sources do not have this provisioning and cannot be manually provisioned by T-Mobile and therefore will not function.
