International Callback

Easy access to the lowest international rates from any country in the world!

If you want to call internationally at extremely low rates from any country in the world, then our International Callback service is the perfect option for you!

How International Callback works

Upon sign-up for the Callback service, customer receives a unique and exclusive US phone number, also referred to as access number. To place an international phone call, the customer first dials the US access number and hangs up at first ring. In a few seconds, our switching center calls the customer's phone number back and gives a message prompting the customer to dial the destination number. You can also use a callback card to help you remember your access number. It's that simple!

International Callback FAQ

1. Will the local telecommunication provider charge me when using the Callback service?

No, the local telecommunication provider will not charge you when using our Callback service. Since you hang up after the first ring on the initial call to your access number, this call is not completed, and therefore you are not charged for this initial call. After you hang up you receive a callback from our network in the USA, which gives you access to United World Telecom's services with significantly lower international calling rates. Your local telecommunications provider will not charge you for this callback either as it is an incoming call to your phone number.

2. How do I place a call using the Callback service?

Dial your access number the same way you would dial a US phone number from your country. After dialing the access number, wait for the first ring and hang up the phone. In a few seconds, your phone will ring and there will be a message prompting you to dial your destination number.

3. Are there any minimum usage requirements?

No, there are no minimum usage requirements for our callback service.

5. How long does it take to open my new account?

It will take 1 to 2 business days to open your account from the time you send us your request for service.

6. Can I use this service from any phone? Are the rates the same?

Yes, our callback service can be used from a mobile phone, a fixed phone, and even from a pay phone (if it has a unique phone number). There is no need for an additional equipment. You only need to make sure that the phone generates DTMF tones (the phone must be set at "tone" mode NOT on "pulse" mode). The rates can vary when calling to and from a mobile phone or a fixed phone, so please check our rates page for more information.
