How much data do I need?

When you sign up for Project Fi, you just need to figure out how much you want to prepay for cellular data each month. This is known as your data budget.

If you're not sure how much data you'll need, you can take the Fi Fit Quiz to find out. You can also look at your past cellular usage to get a sense for how much data you regularly use. See instructions below.

Keep in mind, you can always use as little or as much data as you want.

  • If you go under your data budget, you’ll get credit back.
  • If you get close to your data budget, you’ll get an alert.
  • If you use more than your data budget, don't worry. You'll be charged for the exact difference – at the exact same rate.

Note on international use: When you use data outside of the U.S., it doesn’t come from your monthly data budget. It still costs $10/GB but you’ll be charged separately.

1. Check past data usage

Check your past data usage to help you decide what data budget to select. Here are some ways to check. You can always contact a Project Fi expert and we’ll walk you through it.

Option 1: Check data usage through your phone's settings

Android phone

If you have an Android phone, you can check data usage through Settings. Here's how:

  1. Open the Settings app on your phone .
  2. Under “Wireless & networks,” touch Data usage.
  3. You’ll see your current data usage. You can also view data usage for previous months, as well as how much data each app is using.

Keep in mind the data usage measured by your your device may vary from the amount measured by your carrier.

iPhone

If you have an iPhone, you can find data info in your phone’s Settings. You can use this to calculate your average monthly data usage. Here’s how:

  1. Open the Settings app on your phone.
  2. Touch Cellular
  3. Look at the “Cellular data usage” for the “Current Period.” Note this number. 
  4. Swipe down to the very bottom to see the “Last Reset” date. Calculate the number of months since this date.
  5. Divide the number of gigabytes you’ve used for the Current Period (the number from step 3) by the number of months since you last reset (the number from step 4). For example, if you’ve used 12GB of data over the last 6 months, you’ll average out to 2GB per month. 

Keep in mind the data usage measured by your your device may vary from the amount measured by your carrier.

Option 2: Check your online account or past bill

Look at the online account of your current carrier. Most carriers let you see your data usage. You can also look at past billing statements. 

Option 3: Call your carrier

Call your current carrier for info on how much data you typically use.

2. Choose your data budget

After you look at your recent data usage, you can use this info to set a data budget that's the best fit for you. For example, if you typically use 1.5 GB, you may want to set your data budget at 1 GB or 2 GB.

You'll choose a data budget when you sign up for Project Fi, but you can always change your data budget. You can also learn more about how you're charged for data.
