Switching to amaysim
- Check your phone is unlocked and works on the Optus network, because amaysim uses it. Look at the coverage map for the places you live and work.
- Keep your number: ask amaysim 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 $12 (amaysim 42GB 28-day), then $35 every 28 days.
- None of the 7 amaysim plans we track has a lock-in contract, so you can leave without a fee.
- eSIM (no plastic SIM) is listed on 7 of 7 plans, so you can switch on the spot with a compatible phone.
- Our data says that if your data runs out it stops until the next recharge or month, with no extra charge.
- Deal prices are for new services only. Moving your number to this provider counts as new, but check the terms on the plan page.
