Monitor how much mobile data you use

If you have a Chromebook with a mobile data plan, you can check how much data you've used. If you're using a SIM card, you can even control how much data is used by locking your SIM card with a PIN.

Lock your SIM card

If you're using a SIM card with your Chromebook, you can lock the card at any time to prevent others from accidentally using up your mobile data. Follow these steps to lock your card or change its personal identification number (PIN):

  1. At the bottom right, select the time.
  2. Click Settings .
  3. In the "Network" section, select Mobile data.
  4. Turn on Enable SIM card locking.
  5. Type your SIM card PIN, then select Enter.
  6. Select the "Lock SIM card" checkbox to require a PIN. To set a custom PIN, select Change PIN.

The next time you connect to the mobile network, you’ll need to provide the PIN. Some SIM cards also ask for a PIN provided by your mobile carrier on first use.

If you forget the PIN, or if you see a message asking for a PIN Unlocking Code, contact your mobile carrier. If you enter the wrong Unlocking Code twice, the SIM card will be disabled.
