Warehouse Mobile roaming in Australia: costs, data, and how to save
A plain-English guide to the Warehouse Mobile international roaming, what you'll pay, and a cheaper alternative if you want one.
How Warehouse Mobile roaming works in Australia
A plain-English explainer of why using Warehouse Mobile overseas gets very expensive, very fast.
Warehouse Mobile doesn't sell a daily or pre-paid roaming pack. Instead, every call, text, and megabyte of data you use in Australia is billed at pay-as-you-go rates against your prepay balance. There's nothing to opt into and nothing to switch off in-app — the moment your SIM connects to a partner network overseas, charges start adding up per-use.
| Price per MB of data | $0.58 per megabyte in Australia |
|---|---|
| Cost for ~1GB of data | $580 NZD — that's just one day at KiwiSim's top speed |
| Daily pack available? | No — there is no daily or pre-paid roaming pack |
| Calls & texts | No inclusion — outgoing and incoming calls are charged per minute, and texts per message, at PAYG rates. Receiving a call in Australia costs noticeably less than making one, but there is no free incoming. |
| Hotspot / tethering | Allowed, but every MB tethered to another device is billed at the same per-MB PAYG rate. Hotspotting can drain your prepay balance very quickly. |
| Countries covered alongside Australia | Australia is in Warehouse Mobile’s standard roaming zone. Travel outside the standard zone may revert to PAYG rates or not be supported at all. |
| How to activate or deactivate | Nothing to activate — charges apply automatically the first time your SIM connects to a network in Australia. To avoid charges entirely, turn off "Data roaming" on your phone before you fly, or remove the Warehouse Mobile SIM while overseas. |
You could save big by using a KiwiSim eSIM when roaming in Australia, compared to using your Warehouse Mobile SIM.
