The British Traveller's eSIM Playbook — Every Trip, Every Device, Every Budget
Since Brexit, British travellers have lost the right to free EU roaming — and the major UK carriers have been quick to fill that gap with expensive daily roaming charges. EE, Vodafone, and O2 now charge up to £5 per day to use your phone in Europe, and significantly more further afield. On a two-week holiday in Spain or a business trip to New York, that adds up fast. There is a smarter way. An AloOui eSIM gives you full 4G/5G data from the moment you land, at a fraction of what your UK carrier charges. No store visit, no ID, no SIM swapping.

How eSIM Works — A 3-Minute Guide for British Travellers
An eSIM is a digital SIM card built into your phone. Instead of swapping a physical SIM at the airport or paying your UK carrier's daily roaming charge, you scan a QR code before you fly and your phone connects to local networks the moment you land. No store visit. No ID. No waiting.

Frequently Asked Questions
Can I keep my UK number while using an eSIM abroad?
Yes. Your UK number stays active on your physical SIM or primary eSIM slot. The AloOui eSIM runs on a second slot for data only. You can still receive calls and texts on your UK number — use WhatsApp or iMessage over your AloOui data for outgoing calls to avoid international call charges.
Do I need to turn off roaming on my UK SIM?
Yes — this is essential. Before you land, go to Settings > Mobile Data and disable data roaming on your primary UK SIM. Then set your AloOui eSIM as the default data line. This prevents accidental roaming charges from your UK carrier.
Does AloOui eSIM include hotspot sharing?
Yes. All AloOui unlimited plans include hotspot sharing. You can connect your laptop, tablet, or travel companions' devices to your phone's hotspot at no extra cost.
When should I install the eSIM — before or after I land?
Always install it before you fly, while connected to your home Wi-Fi. The QR code scan requires an internet connection. Once installed, the eSIM activates automatically when you land in your destination country.
Is AloOui eSIM compatible with UK-bought iPhones?
Yes. UK iPhones from XS onwards support eSIM. Most UK iPhones are sold unlocked or can be unlocked once your contract is complete. Contact your carrier to confirm unlock status before purchasing an eSIM.
How do I get support if something goes wrong abroad?
AloOui support is available 24/7. Visit the Help Centre for instant answers, or contact us via live chat on the website.
