Is the $9.95 plan billed monthly? Credit card? Money Order?
The $9.95 is billed monthly on the credit card. If a customer signs up for $25, they are immediately debited $9.95 for the monthly charge, and their balance is $15.06. Should they make no other calls outside the flat rate area, nor exceed their monthly 250 minutes to the designated areas, the $9.95 for the second month would be debited off of that $15.06. Should they make calls elsewhere that are debited off of that $15.06, their credit card will be recharged for an additional $25 before the next $9.95 is debited.
What happens if I exceed my 250 minutes?
Additional calls are billed at the standard flat plan rates.
What are the standard flat rate plan rates?
After 250 minutes, the rates to all countries on the list of the flat-rate promotion are $0.10 per minute (except Ireland, Denmark, and Austria). Ireland and Denmark are $0.11 per minute, and Austria is $0.16 per minute. See the Flat Rate Pricing. pop-up for the complete list.
What are the rates for the Delta Three prepaid plan?
The Prepaid Plan rates are billed on usage, with no monthly fee. View Prepaid Plan Rates.
What about domestic U.S. Calls and Toll Free numbers?
You can use our service to call domestically as well as for toll-free numbers.

1-800, 1-888 and 1-877 numbers are free. Other domestic calls are charged the same rate as calling from outside of the country. Our lines are routed over the Internet and are therefore considered international. It does not matter from where you dial--only TO where you dial.

Please note that you also dial the same way, even if you are calling domestically.

(Country code + area code [drop first zero] + local number.)

Can I Call Mobile/Cell Phones?
Currently you can use our PC-to-Phone system to call cellular phones. There is no extra charge to call cellular phones except when calling to Israel. Mobile phones are charged the rate of the country to which you dial. Even if we have a special offer price for a certain city within that country, the rate is the same as for outside of that particular city.

For example, the rate for calling Brazil is US$0.49/minute on PC-to-Phone, however we have a gateway server in Sao Paolo for which regular PC-to-Phone calls are billed at US$0.29/minute. Calls to cellular phones in Sao Paolo will be billed at US$0.49/minute. Please note that these policies may change in the future for certain countries, and we will keep you informed of any changes through our website.

What are my payment options for the Deltathree prepaid plan?
For the prepaid plan, customers can pay by credit card, or send in a check or money order (address will be provided when you register).
What are the billing increments?
We bill in 6-second increments.
Are there any fees or taxes?
There are no fees, taxes, surcharges, connect fees, per-call charges, or any other hidden costs. Just the per minute price of the call deducted from the prepaid balance, or the minutes as they are a part of the flat-rate promotion.
Is Fax Service Available with Deltathree ?
The Fax Service is still in the testing stages. We plan to have it available in the future however.
Is a Free Trial available?
Our software is FREE to download. You may try our service by calling 1-800, 1-888 or 1-877 numbers in the US for free.
