Getting an account

You open an account by applying at the ‘sign up’ page and simply follow the instructions. After your application has been approved, you will receive an email with your username and password. Once you sign you in, go to your ‘my account’ area to see your rate list, download invoices and make pre-payments.

Each customer can make a couple of test calls before making a pre-payment.


VoiceTrading is only a prepaid service. You can set up your payment plan through your ‘my account’ area and choose either Moneybookers, Ukash, PayPal, credit card or bank transfer.

Available accounts

There are two account currencies: EUR and USD. Your rate lists, payments and billing will be in whatever currency you have chosen.

Available routes

VoiceTrading offers 3 routes (EUR & USD), each with different rates and quality levels:

VoiceTrading Grey: lowest possible rate, no guaranteed quality
VoiceTrading Standard: low rate, high quality
VoiceTrading Premium: slightly higher rate, best possible quality

Every route has it's own dialling format:
