Is there coverage in my area?
Our hotspots connect to T-Mobile's domestic LTE network and do not roam to other carriers’ networks. To decide whether a membership with us is right for you, a good first step is to check the coverage in your area by visiting T-Mobile's interactive coverage map. You can also get an up-to-date, personalized coverage assessment by calling T-Mobile on 1-800-937-8997.
However, it is possible to be in an area of "good coverage" and still experience a very wide range of actual signal strength and speed depending on your exact location with respect to the local cell towers,local network congestion, terrain, and other factors.
One great strategy is to find a friend with a hotspot or cell phone on the T-Mobile network. The speed they achieve on their device is a good indication of what speed you will have on your device.
You can also look up the location of the nearest T-Mobile cell tower via a service like Cellmapper or https://map.coveragemap.com/.
Some important things to note:
- Calyx internet service only works in the United States. There is no coverage in Canada or Mexico for our hotspots, despite what the map shows.
- Calyx internet service only works with T-Mobile towers. Areas that are marked as covered by "Partners" (with diagonal hash marks) are actually provided by different carriers and will not work with our hotspots.
Will my internet service be fast?
It depends.
In practice, 4G is rarely above 40mbps, but it can vary widely by location, time of day, and local congestion. The maximum speed a member has reported with a 4G device (and a MIMO antenna) is 100mbps. It is not uncommon to get 10mbps or less. However, there is no guarantee you will get this kind of speed, and there are a lot of factors that can influence the speed, including obstructions between you and the tower and the congestion on the local carrier network.
If you live in an area with good 5G coverage, many members report download speeds of 300mbps or more. However, there is no guarantee you will get this kind of speed, and there are a lot of factors that can influence the speed, including obstructions between you and the tower and the congestion on the local carrier network. It is also possible to get 30mbps and below—or no signal at all—in a rural area.
What if I have low signal strength?
The Calyx Institute has no control over your signal strength and how fast your internet speed will be. Your results will vary depending on where you attempt to connect, how close you are to the nearest T-Mobile tower, local network conditions, and other factors.
We STRONGLY recommend that you check T-Mobile's coverage map for your area—and if possible, that you test your coverage using someone else's mobile device to see if signal quality is acceptable to you—before you join Calyx Institute. Also please be aware that our terms of service, which members must agree to before joining, stipulate that we cannot be held responsible for the strength, consistency, or reach of T-Mobile’s coverage.
