If you still do not get a dial tone call STC Services. If you can not connect to any other number, try switching phones with a friend and dialing again. If you still can not connect, contact STC Services. If that does not resolve the problem, contact STC Services.
Some modems have a jack where the phone can plug into the modem and use the line.
If yours does not, then replace the modem with a phone and listen for a dial tone. If you do not have a dial tone, try another jack and see the comments above. Questions and comments about billing and usage should be directed to STC Services at x3652.
