Switch over to Hoiio without losing your existing numbers

Good news!

You can now switch to Hoiio while keeping the number you have purchased from other service providers. To express our appreciation for choosing us, we will waive the number retention fee if you subscribe to our services for 1 year. It’s pretty simple, you just need to fill up a form and we will do the rest for you. The number porting process will take 2-3 weeks to complete and you can be assured that we will do our best to make the transition as smoothly as possible for you.


Why switch to Hoiio?

Better and more flexible services

There is no sales person or operator you have to speak to to get your lines up. You can configure your lines easily from the desktop or mobile device. Customised changes take effect immediately so you don’t have to wait for days and weeks anymore. And seriously, we should leave lousy customer service experiences behind. The new year is coming.

Enjoy the best SIP Trunking solution

If you haven’t heard, with Hoiio’s SIP trunk, you get unlimited concurrent calls at no extra charge and no activation costs. And you know we value simplicity and efficiency over most things, so we don’t usually let our customers wait for their lines to be activated. Most importantly, our rates are quite unbeatable at this point. 🙂

Tax benefits

All Singapore companies are eligible for PIC tax claims when you subscribe to our Main Line, Direct Line and Fax services.
