Switching to Cmobile
- Check your phone is unlocked and works on the Telstra network, because Cmobile uses it. Look at the coverage map for the places you live and work.
- Keep your number: ask Cmobile 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.
- Expect a bill, not a recharge: it's postpaid. The smallest first bill is $35 (Cmobile 40GB).
- None of the 6 Cmobile plans we track has a lock-in contract, so you can leave without a fee.
- eSIM (no plastic SIM) is listed on 6 of 6 plans, so you can switch on the spot with a compatible phone.
- Some plans charge for extra data once your allowance runs out; check the plan page so a big month doesn't surprise you.
