Do you know Cingulat affords the 14-day trial period, so does other companies. Most persons don't realize and take advantage of it, like me. Just take a careful watch about the service during this period. Make some calls in every environment. Sometimes the phone shows the signal received, but calls couldn't be sent out. If you are not satisfied with the service, return it within 14 days and get your money back.
Hope this would be helpful to you.

Quaint, quaint, where are you? Did you see my post?
