Commonly Asked Questions

  • Which is the right plan for me?

    Good question.

    Here’s a quick overview of our plans: Unlimited (most popular): 60% of our customers choose this plan, meaning they can use their phone to their heart’s content without worrying about extra costs. If you’re forever streaming, gaming, messaging, scrolling, and everything else-ing, this is the plan for you. 10GB: Our happy medium plan for the average phone user who likes a good scroll, but also takes a break from time to time. 4GB: Our lightest plan for those who might even forget where their phone is from time to time. If you simply want to send the odd work email, have a little scroll on social media, and keep up with pals over WhatsApp, this should do the job.

    Choose the plan that feels closest to your needs and you can change it whenever you like in the app. We’ll even tell you if you could save money by downgrading.
