FAQs
Which plan’s right for me?
We offer monthly rolling plans with no contract, pay as you go plans with no contract, and 18 month contract plans.
Members with no contract can choose to auto-renew their plans for convenience. If this is your case, then choose a monthly rolling plan as it’ll give you more data than our pay as you go plans.
Contract plans auto-renew every month and offer even more data than our no contract plans. With a contract, you can still choose a different plan each month without affecting your contract length. Happy times.

Can I tether with my plan?
Absolutely. You can tether on all our plans.
