Switching to Yomojo
- Check your phone is unlocked and works on the Optus network, because Yomojo uses it. Look at the coverage map for the places you live and work.
- Keep your number: ask Yomojo to move it when you sign up, and don't cancel your old plan first. Your old provider texts a code to confirm, and the move is usually done the same day.
- Pay up front: it's prepaid, so you recharge before you start. The smallest first payment is $24.90 (Yomojo 29GB), then $24.90 every 30 days.
- None of the 4 Yomojo plans we track has a lock-in contract, so you can leave without a fee.
- No eSIM is listed on these plans, so you'll wait for a SIM to arrive.
- Our data says that if your data runs out it stops until the next recharge or month, with no extra charge.

4G only, with download speeds capped at 150Mbps. Unused data expires with the 30-day plan.
eSIM is only offered to numbers ported in, or as a replacement after 30 days of active service, so we don't count it as available to a new customer.
