Ooma voice over i bill Nationwide

Carlos must have purchased an Ooma model that required Regulatory Recovery Fees (RRF or taxes).

Both Costco product brochure and product retail box would have made the RRF requirement clear to Carlos.

Why do I have to provide a credit card when I create my account?

The activation process requires a valid U.S. credit or debit card to link to My Ooma, the online account youll be setting up. Dont worry about hidden charges and fees -- with Ooma there are none! During the activation process youll learn exactly how much the taxes and fees for your local area will be each month. That's all you'll pay unless you choose to sign up for additional services from Ooma.

Contrary to what Carlos said, Ooma DOES NOT force Premier service purchase.  During activation process, Ooma makes it abundantly clear what to expect and what to do before the end of Premier service free trial.

What happens at the end of my free trial?

Starting two weeks before the end of your free trial, we'll send you several emails to let you know that your trial is expiring soon. If you don't wish to continue your subscription to Ooma Premier, simply click the link in one of those emails to log into your My Ooma account and opt out. If you take no action, your account will default to a monthly subscription to Ooma Premier, and your credit card will be billed for the first month of service.

I am a very satified user of the OOMA VIOP phone service and question your experience with the initial setup. The service requires no credit cards for the intial activation and as of August 2009 my setup was initiated within minutes by registering my MAC address (unique number or "address" of the hardware), selecting a phone number and connecting the hardware.

I agree that the service is geared towards enticing new users to create an account for international calling and use of the "premium" features, however this is not required and the unlimited (3000 minutes) of nationwide calling can be enjoyed with no further costs thereafter.

Assuming you are in the USA (I.E. Costo buyer) I would guess that you may have jumped right into the pay feature or do not have an understanding of how to get the system activated in a free capacity.

If you wish, please offer more detail as to why a credit card is required. To my knowledge, this has never been an issue.
