Free Trial

New developers can explore and try all Hoiio APIs free for an unlimited period of time. We hope this will enable you to make an informed decision of whether our API suits your needs.

Trial Benefits

New developer sign-ups get:

  • US$8 or SG$10 (depending on your country) FREE credits
  • Access to all Hoiio APIs

You may use the free credits to pay for your calls, SMS and Hoiio Number purchase.

Trial Restrictions

There are some restriction on trial accounts to prevent abuse:

  • You can only call to, transfer calls to and answer calls from your registered number, Hoiio Numbers that you purchase or our test numbers (+6565918793 and +85258010019).
  • You can only send SMS to your registered number.

Account Upgrade

To lift the restrictions, upgrade your account by making a top-up. Upon topping up, please allow up to 24 hours for us to verify your payment before your account is upgraded.

You get to keep the remaining free credits when your account is upgraded. The credits can be used without any restriction.
