Short answer
Best fit by data per day for most Australians visiting the UK for 1–2 weeks: the 20GB, 30-day plan, $17.90 AUD — about 1.4GB a day over 14 days, sized for everyday maps, messaging, bookings and photo uploads. It is data-only: no local phone number, standard calls or SMS. For lighter use (mostly maps and messaging), the 5GB, 30-day plan is $5.90 AUD, about 0.36GB a day over 14 days. If you want a set amount every day, daily plans start at $3.90 AUD for 1GB a day for 3 days.
| Plan | Price | Data per day | Who it suits |
|---|---|---|---|
| 1GB · 7 days | $1.90 AUD | About 0.14GB over 7 days | Short trips, or messaging and maps only |
| 3GB · 15 days | $3.90 AUD | About 0.21GB over 14 days | Short trips, or messaging and maps only |
| 5GB · 30 days | $5.90 AUD | About 0.36GB over 14 days | Light use: maps, messaging and bookings |
| 20GB · 30 days | $17.90 AUD | About 1.4GB over 14 days | Everyday use, including photo uploads and social media |
| 50GB · 30 days | $36.90 AUD | About 3.6GB over 14 days | Heavy use: video calls, streaming or sharing a hotspot |
| 1GB/day · 3 days | $3.90 AUD | 1GB high-speed | A set high-speed allowance every day; speed is reduced after it is used |
| 1GB/day · 7 days | $8.90 AUD | 1GB high-speed | A set high-speed allowance every day; speed is reduced after it is used |
| 1GB/day · 15 days | $17.90 AUD | 1GB high-speed | A set high-speed allowance every day; speed is reduced after it is used |
| 1GB/day · 30 days | $34.90 AUD | 1GB high-speed | A set high-speed allowance every day; speed is reduced after it is used |
Data per day is the plan’s data divided by the trip length (up to 14 days): a planning average, not a daily allowance or a guarantee it will cover your use.
Will my phone work in the UK?
Your phone can use a travel eSIM in the UK if it supports eSIM and is carrier-unlocked. Check for an “Add eSIM” option or an EID in your phone settings. Your Australian SIM can stay in the phone: with dual SIM it may remain available for calls and texts (your own carrier’s roaming charges apply), while the travel eSIM is used for mobile data. Check your phone.

A UK eSIM gives a compatible, unlocked phone prepaid mobile data in England, Scotland, Wales and Northern Ireland without swapping out your Australian SIM.
Choosing a plan for United Kingdom
Fixed-data plans (United Kingdom eSIM) give one data allowance to use over the validity period; it does not reset each day. They suit travellers who mostly use maps, messaging and bookings.
Daily plans (United Kingdom Unlimited eSIM) give a high-speed allowance each day for the number of days you choose. After the daily allowance is used, speed is reduced until the next day. They suit heavier daily use, such as video calls or sharing a hotspot.
Coverage in the United Kingdom
On 16 October 2026 the United Kingdom plans listed the O2 (5G), EE (5G) and Three (4G) networks. Coverage varies between cities, the countryside and underground rail, so plan for gaps on some journeys.
Visiting Ireland or Europe as well?
A United Kingdom plan covers the UK only. For a trip that includes the Republic of Ireland, compare the Ireland & UK eSIM. For travel on the continent, see the Europe eSIM guide and check that every country on your route is in the plan's coverage list.
Moving to the UK on a working holiday? See a travel eSIM for a working holiday or study abroad.
How much data do you need?
Start from your phone's recent mobile-data use at home, then add headroom for navigation and uploading photos. As a planning example, 20GB over 14 days is about 1.4GB a day; over 7 days it is about 2.9GB a day. Video streaming, video calls, cloud backups and hotspot use add up quickly, so save them for Wi-Fi or choose a larger or daily plan. The travel data planner has daily budgets for 7, 14 and 30 days.
Using your Australian number
These plans are data-only: they do not include a local phone number, standard calls or SMS. A dual-SIM phone can keep your Australian SIM installed for calls and texts while the travel eSIM carries mobile data. Turn off data roaming on the Australian line if you want to avoid your carrier's roaming charges, and check your carrier's terms for incoming calls and texts.
Messaging and calling apps such as WhatsApp, iMessage and FaceTime work over the travel eSIM's data. More on how this works: what an eSIM is and keeping your Australian number overseas.
UK eSIM setup
- Confirm your exact phone model supports eSIM and the phone is carrier-unlocked (compatibility guide).
- Install the eSIM from the QR code in your delivery email while on reliable Wi-Fi, ideally before you fly.
- Label the new line “UK” so it is easy to pick in your settings.
- On arrival, set the travel eSIM as your mobile-data line, turn on data roaming for that line, and follow the plan's activation instructions.
Step-by-step guides: iPhone, Samsung, Google Pixel and the general installation guide. If it does not connect, see troubleshooting before deleting anything. Payment, delivery and your order page are explained in how Telroo works; for the trip itself, see keeping your phone safe overseas and, once you are home, what to do with the eSIM after your trip.
UK eSIM questions
Can I use my phone as a hotspot in the UK?
The United Kingdom plans listed hotspot support on 16 October 2026. Hotspot traffic uses the same data allowance; see sharing data with a hotspot.
Does a UK eSIM include a UK phone number?
No. The plans are data-only, with no local number, standard calls or SMS.
Will it work in the Republic of Ireland?
Only if Ireland is in the selected plan's coverage list. The United Kingdom plan covers the UK; the Ireland & UK plan covers both.
