Latency is also measured while the upload test is in progress to see how it is affected by upload activity on your network, like someone on your home network uploading a year’s worth of photos. Latency is measured while the download test is in progress to see how it is affected by download activity on your network, like a household member downloading a large game while you’re trying to work.

This is a measure of how long it takes a server to respond to your request in the first place. More realistic latencyĪlthough download and upload speeds are of course the main thing people like to measure, there’s one other important number that can have a big impact on your experience: latency. Slide down from the top to switch between Best and Most Common speeds. Carriers love to quote their fastest speeds, even if those are only available in a few small patches here and there. You can also see the difference between theory and practice. Slide that up to change to a different carrier to see how their coverage compares. To use it, tap the Maps tab and you’ll see one of the carriers at the bottom.

If you’re looking to change operators, you can check to see who has the kind of service you need in the locations you visit most often.

Then you can take that information to your operator to ask them to improve service in that area.

If you consistently find yourself dropping calls in the same spot on your daily walk, you can check our map to see if others who use the same provider are experiencing the same thing in the same area.

If you’re looking to use your brand-new 5G phone on an upcoming vacation, you can check the map to see if your operator had 5G service in that location.
