That's incorrect. I have signed up and they never asked me to change my local or long distance carrier and I am in US.
Dear Valued Startec Customer,
Thank you for choosing Startec as your new long-distance service provider. We look forward serving you.
At this time, however, we have been unable to process your recent request to switch to Startec because there is a switching restriction on your line.
In order to remove this restriction, please contact your local phone company and ask
them to add Startec as your long distance and local toll provider (selecting Startec as your local toll provider is optional, but will help simplify your billing). All you have to do is let your local phone company know that you want Startec (code 0444) to provide your long distance services.
When this process is complete, please call our test number at 1-700-555-4310 to confirm that Startec is your primary long-distance service provider.
In addition, please notify one of our PIC department specialists at 1-800-213-6004
(9:00 AM-11:00 PM Monday through Friday, and 9:00 AM - 5:30 PM Saturday, Sunday,
and holidays, EST) that this process is complete, and give them the confirmation number provided to you by the local phone company.
If you are unable to contact your local phone company, please feel free to contact our PIC department and we will be happy to assist you.
We hope that this issue can be resolved quickly, and in the meantime, we suggest that you continue to dial 1-800-483-1494 before all of your long-distance calls so that you benefit with terrific savings from our great low rates.
With Best Regards,
Startec Customer Care Team
