Sign up for our one simple plan
Our plan starts with the Fi Basics for $20 per month. This includes:
Unlimited domestic talk and text
Unlimited international texts
Low-cost international calls
Coverage in 120+ countries
Then it's $10 per GB for data. $10 for 1GB, $20 for 2GB, $30 for 3GB and so on. That's it. With no annual contract required.
Never pay for unused data
It's hard to predict your data usage when it changes month to month. One month you're streaming live sports, the next you're mostly just checking email. At the end of each month, you’ll get your unused data credited in dollars and cents, so you only pay for what you use.
Use your phone number with tablets and laptops too
Talk, text, and check voicemail with the screen nearest you. Your phone number now works with more than just your phone. Connect any device that supports Google Hangouts (Android, iOS, Windows, Mac, or Chromebook) to your number. Then, talk and text with anyone—it doesn't matter what device they're using.
Pay one rate for data around the world
In 120+ countries, data usage costs the same $10 per GB as it does in the US (data speed is limited to 256kbps/3G). Check email, get directions, and keep in touch with friends and family when on your trip. Also, call around the world for 20c per minute and send unlimited international texts.
If you have a smartphone, you are carrying around a supercomputing sensor array. Modern phones don’t just make calls, they are also constantly aware of their environment. They know where they are using GPS and mobile telemetry. They know their orientation and motion using gyroscopes and accelerometers. Many measure barometric pressure. They can record images and sound, and can communicate with the global internet. And there are about 1.5 billion of them.
With all those sensors across the globe, there’s a lot of interesting studies you can do. You can use mobile data to analyze traffic flow in major cities. You can study weather with barometer measurements from phones. You can also do some interesting astrophysics, because even though phones aren’t designed to take astronomical data, they still do.
For example, your phone can detect cosmic rays. Not directly, but it can detect muons produced in the shower of particles caused by cosmic rays. It does this through the phone’s camera. Digital cameras work through what is known as the photoelectric effect. When light strikes a charged silicon wafer, electrons are released, which creates a current. This is then recorded in your phone’s data. If you block the light coming into the camera, there shouldn’t be any generated currents. But muons from cosmic rays can penetrate the camera and strike the silicon wafer, producing a current. So with the right setup you can detect cosmic rays with your phone.
As the saying goes, there’s an app for that. Actually a couple. One is called DECO, and it works on Android phones. Another is known as CRAYFIS. Both of these apps are part of larger projects trying to crowdsource cosmic ray data gathering. If you like playing with your phone a bit, and want do participate in high-energy astrophysics, they are worth checking out.
Projects such as these are only going to get more common. As phones get smarter and more common, there will be more data available to be analyzed. It will be interesting to see what we can learn with our powers combined.
