I've had my OPEX service now for more than a year and I love it. Just being able to have the toll free number so inexpensively is worth it to me. I saw such a dramatic decrease in my long distance expenses and I've told lots of people about your service.
Thank you!

I must tell you how easy it was for me to pay my bill on-line. I've had to cancel with other companies because they make it too difficult to sign in and make payments. Thank you for being so wise in your on-line.

I love OPEX I cannot believe that everyone doesn't switch to this wonderful long distance plan. I have NEVER received an offer that beats my long distant rates, and I even have a toll free number that bills me at the same rates as I get when making calls! Other companies wanted over six times what I pay per minute for toll free service! I simply cannot say enough good things about OPEX
