Our Difference

The Resolver Group Difference

We are bringing high quality Telco Services back to the Australian Market. Over the past decade, our telecommunications services seem to have gotten worse within Australia. We are here to change that and give this industry a fresh shake up by bringing back quality service and support.

No Flagfall

Some of our competitors still charge a “flagfall” charge to simply connect the call, in addition of the actual call charges. We don’t feel you should have to pay extra just for your call to be connected and as such do not charge you a flag fall.


No Lock-in Contracts

Unlike some of our competitors, we don’t believe in contracting our customers. Why should you be forced to stay? Our goal is to keep our customers happy at all times so that they stay by choice, and not with the threat of early termination fees!

Australian Based Support

We understand that it can be frustrating when you need support. When you’re in a bind, we appreciate that you don’t want speak with an outsourced support team, who don’t have the time or training to deliver you a fast outcome. Our support team is entirely Australian-based, and ready to help if you need it.

Below are the answers to some of our most frequently asked questions. If you have a question that isn’t answered here, please get in touch with our friendly team who will be happy to answer all of your questions.

Do you offer a trial?

We offer a free trial of our PAYG Plan, which will provide you with 1 month of service and $5 of prepaid call usage. To minimise abuse of this trial product, and so that we can keep it available for more people to use, we do require you to send a quick email to [email protected] requesting a trial.

Where are your servers located?

To ensure optimal quality for our customers we have servers located in Queensland, New South Wales, Victoria and Western Australia. All of our Systems are located with NextDC Data Centres to ensure optimal security.

Are there cancellation fees?

All Resolver Group plans run on a month to month basis. As such, there are no cancellation fees if you decide to leave. We simply ask for feedback when you’re looking to leave, so we can continue to improve our service offerings moving forward. We understand that we aren’t the best fit for everybody, and don’t believe in punishing you for that by forcing you to stay.

Can I bring my own number?

Yes! We are able to port your number from all carriers within Australia. If you wish to bring your own number, simply fill in our easy-to-use Porting Application Form, and we will do the rest for you.
