GSM-T utilizes LTE Bands: 2 (1900MHz), 4 [66] (1700MHz), 5 (850MHz), 12 [17] (700MHz), 25 (1900MHz), 26 (850MHz) and 41 (2.5GHz) and 71 (600MHz)

GSM-T utilizes 5G Bands: n41 (2.5GHz), n71 (600MHz), n77 ("C-Band" 3.7-4.2GHz - future), n258 (26GHz), n260 (39GHz), n261 (28GHz)

July 2020: Sprint LTE Bands include 25 (1900MHz), 26 (850MHz) and 41 (2.5GHz) and are being integrated in to T-Mobile's network.

5G Devices should use the fast.t-mobile.com APN with IPv4/v6 enabled.

LTE Devices should use either the b2b.static or fast.t-mobile.com APNs and in some cases may require other configuration depending on the device capabilities.

Flat-Rate (Approved Device) LTE/5G Plans:

• Mikrotik Routerboards** (including but not strictly limited to R11e-LTE-US or WAP Kit US/WAP AC Kit US, LtAP mini LTE Kit US, SXT LTE Kit US, LHG LTE Kit US, Cat 4 versions only, no Cat 6 (see below), see below; including ANY Mikrotik Routerboard with an mPCI LTE module supporting LTE and/or 5G bands listed above, such as Quectel EC25-AF, EP06-A etc). Must use ISPWN configuration file.
• Any router using OpenWRT

If you plan on to using a device not on our list with an "approved devices" flat-rate or unlimited plan, there is no guarantee that services will work at full speed (or at all) and we are unable to provide support for devices we are not familiar with.

If you'd like us to test whether your device(s) will work with these plans, please send a unit to us and we will test it with various configurations so we can determine compatibility - we can also test your device with other carriers if required.

Requires Further Testing:

The below devices are known to work to some extent, but may end up being deprioritized or throttled (or may not work at all). We have also seen instances where some devices will perform perfectly on a speed-test, but not during real world usage:

Flat-Rate (Basic Device) LTE Plans:

The below devices are known to work on the "basic device" plans, and may end up being deprioritized or throttled if used on an "approved device" plan (or may not work at all). We have also seen instances where some devices will perform perfectly on a speed-test, but not during real world usage if used on an "approved device" plan:

• Huawei H8372H USB Dongle
• ReadyNet LTE520
• Peplink - all models

Flat-Rate Plan Exceptions (not eligible for use on flat-rate/high-usage plans):

• T-Mobile branded hotspots (such as Alcatel Linkzone, ZTE Z915, ZTE Z917, MF64 etc) are not compatible with high-usage, flat-rate or unlimited plans and can only be used on limited data plans (2 to 22GB).
• T-Mobile KonnectONE Hotspot/GPS
• T-Mobile Home Gateway
• AT&T branded hotspots (such as ZTE MF275, MF279, Novatel 66xx etc)
• R2
• Most ZTE devices
• Most Huawei devices (including but not limited to B310-518s)
• Netgear LB1120 (As of November 1, 2021, lines found to be using this device may be disconnected by the carrier without warning, notice or recourse).
• Netgear Nighthawk M1 (MR1100-1A1NAS, MR1100-2A1NAS) (Update 5/20/2020: May not work at all on GSM-T - existing devices may continue to work until further notice, new activations not accepted).(As of November 1, 2021, lines found to be using this device may be disconnected by the carrier without warning, notice or recourse).
• Netgear Nighthawk M1 (MR1100-100NAS) (Update 5/20/2020: May not work at all on GSM-T - existing devices may continue to work until further notice, new activations not accepted). (As of November 1, 2021, lines found to be using this device may be disconnected by the carrier without warning, notice or recourse).
• Netgear Nighthawk MR1108 (As of November 1, 2021, lines found to be using this device may be disconnected by the carrier without warning, notice or recourse).
• GotW3 devices (C4R400 and GotW3 versions of the LTE520) will not be activated on GSM-T at all.
• Cradlepoint - all models
• MOFI4500-4GXeLTE-V2 (both SIM4 and SIM7 versions)****2020-09-25 These were previously approved but they are no longer allowed.
• T-Mobile's engineering team has informed us that they have revoked authorization for a number of Telit chipsets (such as LM960A18) to be used with Flat-Rate plans. These chipsets are still authorized for use on the T-Mobile network, however, may only be used on IoT/M2M and limited data plans. We have not been offered an explanation for this change, but we suggest using a different module in your device if you intend to activate a flat-rate plan. 

Lines found to be using these devices may be disconnected by the carrier without warning, notice or recourse.

Should not be used on the network at all until further notice:

Mikrotik LTE6 variants (r11e-LTE6, SXT-LTE6, LDF-LTE6, LHG-LTE6 etc) can sometimes be problematic to activate & use. The r11e-lte6 chipset in use in these devices does not support LTE Band 4 or 66 (let alone 71), and while some customers are using these successfully in some areas, many service areas rely on Band 4 for speed and the lack of this band may severely impact the customer experience or result in no connectivity.
