Frequently Asked Questions

What is an eSIM and how does it work in the UK?

An eSIM is a digital SIM card embedded in your device. After purchasing, you receive a QR code by email. Scan it to install the UK eSIM profile — no physical SIM required. Your device connects to local UK networks automatically.

Can I get a UK phone number with my eSIM?

Yes! AloOui's UK Number Plan gives you a real +44 UK phone number with your eSIM. You can make and receive local UK calls, send and receive SMS, and use it for verification codes — all on the same eSIM. It's ideal for travelers who need more than just data.

Which plan is best for traveling around the UK?

We recommend the Unlimited Essential plan for most UK travelers. Its 4G LTE speeds are perfect for navigating London, exploring Edinburgh, and staying connected across England, Scotland, Wales, and Northern Ireland. If you need to make local calls or receive texts, choose the UK Number Plan. For business travelers or heavy data users, consider Unlimited Plus for Max Priority coverage.

Is my phone compatible with AloOui eSIM?

Most modern smartphones support eSIM, including iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3 and later, and many others. Check your device settings or manufacturer website to confirm eSIM compatibility.

Can I keep my existing number while using the UK eSIM?

Yes! Your AloOui eSIM runs alongside your existing SIM. You can keep your home number active for calls and texts while using the UK eSIM for data — no need to choose between them.

Does the UK Number Plan support WhatsApp and OTP verification?

Yes — because you get a real +44 UK number, it works for SMS-based OTP verification, WhatsApp registration, and any service that requires a UK mobile number. This is a genuine UK number, not a VoIP workaround.

When does my plan start?

Your plan activates when you first connect to a UK network — not when you install the eSIM. So you can install it before you travel and it won't start counting until you arrive in the UK.
