Having trouble activating to Verizon 3G? Try this.

I was getting connectivity errors when trying to connect to 3G, but I got it working after following the steps below:

1. Go to chrome://system

2. Find mm-status and click the Expand... button to its right

3. Find payment_url:

4. Go to the URL listed next to payment_url:

5. Follow the instructions on the website that comes up

6. Make sure Cellular is enabled

7. Attempt activation again.

EDIT: You must already be connected to the internet (via wifi or ethernet) for these steps to work. You must also have the cellular radio enabled. Thanks to OrthoStice and atm153 for pointing out these omissions.
