Why Travellers Choose HelloRoam eSIM Cards for Overseas Travel

  • Flexible eSIM data plans

    Pick a fixed eSIM data plan from 3GB to 20GB, or go unlimited in most of our 185+ countries. Fixed plans are sorted for a week in Bali or a fortnight in Europe. Unlimited day plans suit daily video calls, at one set price per day. Plans start from A$1.46 with no contract and no lock-in.

  • Set up in minutes, easy as

    Buy your travel eSIM online, get a QR code by email, and scan it in a few minutes. Your e SIM activates the moment you land. No queuing at Sydney, Melbourne, or Brisbane airports. No hunting for a SIM card shop at Bali or Bangkok. The whole setup takes under 5 minutes on any eSIM compatible phone.

  • Global and regional coverage

    Pick a single-country plan or go regional. The Europe plan covers 33 countries, and the Asia plan covers 19 destinations including Bali, Bangkok, and Tokyo. Good value if you're hitting multiple stops on the one trip, no swapping eSIMs between countries.

  • Keep your number for calls

    Your eSIM handles data while your main Telstra, Optus, or Vodafone AU SIM stays active for calls and texts. WhatsApp, iMessage, and all your usual apps keep working on your original number. Your mates and family back home can always reach you.

  • Local 4G and 5G networks

    Connect to local 4G and 5G networks in each country. Use maps, messages, and video calls on the same networks locals use, not a shared hotel Wi-Fi line.

  • 24/7 Support

    Our team is on deck 24/7 via WhatsApp, live chat, and email at help@helloroam.com. Reach us before you board, mid-trip, or once you're back home.

eSIM vs Physical SIM: How Does eSIM Work?

An eSIM vs a physical travel SIM card: an eSIM is a digital profile stored inside your phone, while a physical SIM is a removable chip you slot in by hand. eSIM compatible phones like iPhone XS and Samsung Galaxy S20 let you switch international data plans in seconds without opening a SIM tray. No queuing at Bali or Tokyo airports, no hunting for a kiosk. Prepaid travel data from A$1.46 replaces the hassle of a physical SIM card. That's why savvy travellers heading overseas pick an e-sim for mobile data abroad. All three spellings cover the same technology: eSIM, e SIM, e-sim. HelloRoam covers 185+ countries worldwide.

On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!

Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.

FAQs

Is HelloRoam cheaper than Telstra international roaming?

HelloRoam costs less than Telstra international roaming for most trips. Telstra's International Day Pass is $10 AUD per day and Optus Travel Pass is $5 AUD per day. HelloRoam eSIM plans start from A$1.46 for fixed data across 185+ countries, with no daily fees. On a 14-day Bali or Japan holiday, that saving adds up fast. Plans are prepaid with no contract, so you only pay for what you need.

How do travel eSIM plans connect you to local networks abroad?

A travel eSIM connects your phone to a local partner network in each country as if you were a local subscriber. You buy a HelloRoam plan online, receive a QR code by email, and scan it in your phone settings. When you land, your phone finds the partner network and connects on its own. You use the local 4G and 5G networks locals use, not a home-carrier roaming deal. No SIM tray to open, no airport kiosk, and no Telstra or Optus roaming bill on your return. All HelloRoam eSIM profiles meet GSMA SGP.22 security standards.

Is HelloRoam better than Optus Travel Pass?

HelloRoam gives a better option than Optus Travel Pass for trips to destinations outside the Optus zone or where the $5/day charge adds up over a longer holiday. Optus Travel Pass works in selected countries only and still charges per day. HelloRoam eSIM plans start from A$1.46 as a one-off prepaid charge, not a daily fee, covering 185+ countries. For Bali, Japan, and Vietnam, HelloRoam gives you wider coverage and better value. It's different from Airalo in that it offers both fixed and unlimited plans, plus a refund on unactivated eSIMs within 180 days.

Are prepaid travel eSIM plans worth it for Australian travellers?

Prepaid travel eSIM plans save Australian travellers significant money compared to Telstra's $10/day International Day Pass and Optus's $5/day Travel Pass. HelloRoam gives you a flat-cost plan you buy once, not a daily meter that keeps running. Your Telstra or Optus SIM stays active for calls and texts while the HelloRoam eSIM handles data. For a 10-day Bali or Japan holiday, the total cost is a fraction of what either carrier charges. Plans are prepaid, no contract, and activate when you land.

Can I use eSIM in multiple countries?

HelloRoam offers regional plans that cover multiple countries in Asia, Europe, and the Americas with a single purchase. For a trip across Bali, Thailand, and Vietnam, a single Asia regional plan keeps you connected without swapping eSIMs. Plans start from A$1.46. You can also store separate country plans and switch between them in your phone settings.

Which eSIM plan works best for heavy data use overseas?

HelloRoam unlimited daily plans suit heavy data users who stream video or join video calls while travelling. Fixed data plans from 3GB to 20GB work for lighter usage. Fixed plans cover 185+ countries and unlimited plans cover most of them, on local 4G networks, with 5G where available. For digital nomads who tether a laptop, an unlimited day plan keeps the cost fixed for each day.

eSIM Travel Glossary

How Does an eSIM Work?

An eSIM works by downloading a carrier data profile to the chip built into your phone, no plastic card required. HelloRoam sends a QR code to your email. Scan it before you fly, and your mobile connects to a local network the moment you land in Bali, Tokyo, or Bangkok. Setup takes under five minutes.

eSIM for International Travel

An eSIM is one of the most practical options for overseas travel because you activate a local data plan before you board. No Telstra $10/day International Day Pass, no Optus $5/day Travel Pass, no airport SIM kiosk queues. HelloRoam travel plans start from A$1.46 and cover 185+ countries. If you never activate the eSIM, you can get a refund within 180 days.

eSIM Card

An eSIM card is the embedded chip inside compatible smartphones and tablets that stores your carrier profile digitally. Unlike a physical SIM you slot in by hand, an eSIM card holds multiple profiles at once. Switch between your home Telstra or Optus plan and a travel data plan without touching a SIM tray.

eSIM Disadvantage

The main disadvantage of an eSIM is device compatibility. Older mobiles and some budget Android models still require a physical SIM card. Once an eSIM profile is installed on a device, it cannot be moved to another phone. Most flagship iPhones and Samsung Galaxy handsets released from 2020 onward support eSIM natively.
