Landing in the U.S.? A local SIM card or eSIM can save you from pricey roaming fees and dodgy public Wi‑Fi. Whether you're navigating New York with Google Maps, booking a rideshare in LA, or uploading your best selfies from the Grand Canyon, having reliable data is a must. U.S. roaming charges can be steep. This is especially true if you're road-tripping across states or working remotely. A prepaid SIM or eSIM from platforms like Traveloka will give you fast 5G/4G access without a contract. It’s perfect for short visits or data-hungry Aussie travellers.

Roaming vs getting a local SIM in the United States

Roaming might feel easier, but daily charges (AU$5–10) can add up fast. Local prepaid options offer better value: for example, T‑Mobile’s unlimited 30‑day plan is around US$50 (about AU$75) — cheaper than most Aussie roaming bundles.

While some Aussie providers offer free roaming perks, they often limit speed or cap data. For anything longer than a stopover, a U.S. SIM or eSIM is typically faster, more generous, and a much better bang for your buck.

Getting a SIM card or eSIM for the United States

Getting connected in the U.S. is easy. You can buy prepaid SIMs from airports, pharmacies, or stores. Or skip the queues and get an eSIM from Traveloka before you fly. eSIMs are activated via QR code and work on arrival — no ID needed. Just make sure your phone is unlocked and eSIM-compatible before purchasing.

Buying a SIM card at the airport vs in advance

Airport SIMs are quick, but not cheap. At hubs like New York’s JFK or Los Angeles’ LAX, prices can hit US$70–80 (about AU$105–120) for limited data kits. In contrast, in-town stores offer better deals.

Even better? Buy an eSIM online before you fly. Pro tip: install it beforehand or while in-flight (if you’ve got Wi‑Fi) so you’re connected before landing. Just double-check that your phone supports eSIM and is unlocked.
