Its been discovered that a new update to Google’s Chrome OS now allows GSM support for the Gobi 3G chip that’s in Google’s Cr-48 notebook. Google’s new Cr-48 notebook is currently under beta testing and locked to Verizon’s network but if you are one of the luckily few and fancy hoping to another network the hack is easy to complete.
So if you running your new Cr-48 on another network, AT&T or maybe T-Mobile, you will need to jump into developer mode, enter a few terminal commands, and make sure you have the correct access point.
- Pop your SIM card into the slot under the battery (must be a full-size SIM, microSIMs you’ll just lose in there, fine if you use an adaptor though)
- Make sure you’ve enabled developer mode – do this by flipping the switch under your battery
- Once you’re booted into developer mode and logged in, press Control-Alt-T
- This opens crosh, a limited command shell. Since we’re in developer mode, we can get a full shell. Type the word shell and press enter.
- You’ll get a shell that starts with ‘chronos@localhost / $’. Once you’ve got this, we can type in the command that flips over to GSM.
- Type the following command: modem_set_carrier “Generic UMTS”
- Wait a couple of minutes, then you can exit the shell by typing exit twice.
- Your 3G should be usable assuming you have an active service plan on that SIM card, and that ChromeOS knows your APN setting
