These two units, when used together, allow you to bypass T-Mobile's hotspot limit to get unlimited high speed data.

Q: How much of a speed am I getting?

A: The performance depends on your location, i.e. your proximity to a T-Mobile tower.

If you live in an area which has good T-Mobile wireles signal, you could receive a speed more than 100Mbps.

If you live in an area which has weak T-Mobile signal, your speed could be lower than 10Mbps.

Q: I am confused about mobile data vs hotspot data. Can you explain?

A: The best way to understand what the restriction is and how to solve the problem is google "use ttl to bypass hotspot limit". If you are still confused about what it is, this listing may not be for you.

Q: What exactly are included in this listing?

A: Two units. The white unit is the T-Mobile router that receives data from T-Mobile. The smaller unit is the router that changes TTL to 65.

Q: Can I just use the white unit (mobile broadband router)?

A: If you use this less than 10GB/month, yes, you can live with the white unit only. However most people use probably 300GB or more. In this case, you will be throttled down to 2G speed (about 128Kbps). The black unit lifts the 10GB hotspot restriction. You will be able to enjoy unlimited high speed 4G 5G data.

Q: How fast is video streaming?
A: Video typically streams at DVD quality (480p). You can install a VPN client in the router to receive 4K UHD streaming.

Q: Does it support 5G?
A: Yes, it supports 5G.
