Notes:

1. While you are connected to the test servers, you can either use your own phone number or use public phone numbers. These are more limited. Test phone numbers are of the form 99966XYYYY, where X is the dc_id to connect to (between 1 and 5), and Y are random numbers. The code will be XXXXX (the dc_id you chose repeated 5 times).
