If you’re flying from Australia to Europe and hitting more than one country, the single best move is a regional Europe eSIM — one plan that works across 30+ countries, so you don’t swap SIMs or re-buy data at every border. A Travelren Europe regional plan starts at around AUD$8, against roughly AUD$5/day on Telstra or Optus roaming (about AUD$70 for a two-week trip). Here’s the honest comparison, the coverage map, and exactly how to set it up before you leave.
Travelren is an Aussie-built eSIM brand and we sell Europe regional plans, so this has stakes. We’ve put the real numbers down — including the cases where keeping your Telstra or Optus Day Pass on is the smarter call.
The quick answer
- One regional eSIM beats per-country SIMs for any multi-country Europe trip — France + Italy + Spain runs on a single plan, no border swaps.
- Travelren Europe regional eSIM: from approximately AUD$8 (small data) up to around AUD$40 (unlimited / 30 days).
- Telstra International Day Pass / Optus Roaming in Europe: approximately AUD$5/day (Europe is the cheapest “Zone 1” tier for both) — about AUD$70 over a 14-day trip.
- Crossover: the eSIM is cheaper for any trip longer than a couple of days.
Why a regional plan, not a SIM per country
Europe is the one region where regional eSIMs genuinely shine, because the typical trip is multi-country: London then Paris then Rome, or a Mediterranean loop through Spain, France, and Italy. Buying a local SIM in each country means queuing at an airport kiosk, swapping cards, and losing your data the moment you cross a border. A regional eSIM stays connected as you move — the same plan roams across the whole coverage list automatically.
It also keeps your Australian number reachable. Install the eSIM for data and leave your Telstra or Optus SIM in the phone (with its data roaming switched off) so bank 2FA texts and calls still land — a dual-SIM setup every modern iPhone and most Androids handle natively.
What Telstra and Optus roaming costs in Europe
Both major Australian carriers treat Western Europe as their cheapest roaming tier:
- Telstra International Day Pass: approximately AUD$5/day in Europe (Zone 1) for unlimited talk + text and a daily data allowance, auto-activating on first use each day.
- Optus International Roaming: approximately AUD$5/day in eligible European countries on a similar daily-pass model.
- Both charge only on days you use the network — but background syncs and notifications trigger the charge, so a WiFi day can still cost you AUD$5 if data roaming is left on.
At AUD$5/day, Europe roaming is far more reasonable than Zone 2 destinations like Bali (AUD$20/day). The eSIM still wins on cost for longer trips, but the gap is smaller — which is why the break-even below matters.

Break-even math (14-day Europe trip)
| Trip length | Telstra / Optus (~$5/day) | Travelren Europe 5GB / 30 days | Cheaper option |
|---|---|---|---|
| 2 days (city stopover) | AUD$10 | AUD$18 | Roaming saves AUD$8 |
| 4 days (long weekend) | AUD$20 | AUD$18 | eSIM saves AUD$2 |
| 1 week | AUD$35 | AUD$18 | eSIM saves AUD$17 |
| 2 weeks (standard Euro trip) | AUD$70 | AUD$18 | eSIM saves AUD$52 |
| 3 weeks | AUD$105 | AUD$28 (10GB) | eSIM saves AUD$77 |
| 1 month (grand tour) | AUD$150 | AUD$40 (unlimited) | eSIM saves AUD$110 |
Note the crossover: for a 1–2 day stopover, the AUD$5/day Day Pass is actually cheaper than committing to an eSIM plan. The eSIM pulls ahead from about day four and the gap widens fast on a standard two-week trip.
Which countries does the Europe plan cover?
A Travelren Europe regional plan covers the major destinations Australians actually visit — the UK, France, Italy, Spain, Germany, the Netherlands, Greece, Portugal, Austria, Switzerland, and most of the EU, plus popular add-ons like Croatia and the Czech Republic. Always check the live coverage list on the Europe plan page before buying, especially for edge cases like Turkey, the Balkans, or non-EU microstates, which are sometimes priced separately.
When Telstra or Optus roaming is the better call
- Very short trips — a 1–2 night stopover in London on the way to somewhere else. At AUD$5/day, the Day Pass beats buying a 30-day eSIM plan you won’t use up.
- You make lots of voice calls — the Day Pass includes calls; the eSIM is data-only, so you’d use WhatsApp or FaceTime.
- Your phone isn’t eSIM-capable — check our device compatibility page.
- Single-country, single-purpose trips where your AU number must stay primary and you don’t want a dual-SIM setup.
How to set it up before you fly
- Buy the Europe regional plan before you leave Australia, on home WiFi.
- Install the eSIM via the QR code or one-tap link — this just adds the profile; it doesn’t activate data yet.
- Label it “Europe” in your phone’s mobile settings so you can tell it apart from your Telstra/Optus line.
- On landing, switch the Europe eSIM to your data line and turn off data roaming on your Australian SIM. Leave the AU SIM on for calls and texts.
- Toggle “Data Roaming” on for the eSIM line specifically — regional eSIMs technically roam, so this switch must be enabled for that profile.
Common questions
Is the UK included in a Europe plan post-Brexit?
On most regional Europe eSIMs, yes — the UK is still bundled in the Europe coverage list despite Brexit, because eSIM coverage is set by carrier roaming agreements, not EU membership. Confirm it on the plan page if the UK is a key stop.
When does my 30-day window start?
Validity typically starts when the eSIM first connects to a network in Europe, not when you buy it — so you can safely purchase and install days before departure. Check the specific plan’s terms to be sure.
Will I keep my Australian number?
Yes, if you run dual-SIM: the eSIM carries data while your physical Telstra/Optus SIM keeps your number live for calls and 2FA texts. Just switch the AU line’s data roaming off so it doesn’t rack up Day Pass charges in the background.
Can I tether my laptop?
Yes — Travelren Europe plans allow hotspot/tethering. For a working trip, the 10GB or unlimited tier is the sensible choice so you’re not rationing data across a laptop and phone.
The bottom line
For any Europe trip from Australia longer than a couple of days, a single regional eSIM is the cheaper, simpler choice — one plan across the whole continent, no border swaps, from around AUD$18 for a typical two-week trip versus about AUD$70 in Telstra or Optus roaming. Keep your Australian SIM in for calls, run the eSIM for data, and you get the best of both. The one genuine exception is a quick 1–2 night stopover, where the AUD$5/day Day Pass wins.
