UK networks and hotspot sharing

AloOui UK connects to Three UK, O2 UK and Vodafone UK, with 4G/5G where available. The extra Unlimited data-only and 500-minute/500-SMS options use O2 UK.

Share your data with a laptop or travel partner through hotspot on supported devices. Shared data uses the same allowance.

Install before departure, activate in the UK

1. Check that your phone supports eSIM and is carrier-unlocked.
2. Install the emailed QR code over Wi-Fi and follow the order's instructions. Label the line AloOui.
3. Restart after installation. In the UK, turn on AloOui, select it for mobile data and enable data roaming on that line.

Your plan starts when you connect in the UK, not when you install it. Install at home and you're online as soon as you land. Tip: turn off data roaming on your home SIM to avoid charges from your carrier.

APN and quick fixes

Most phones set up automatically. If needed, set the APN to data.esim with username and password blank, then restart or briefly toggle airplane mode. Make sure AloOui is selected for mobile data with roaming on.

Still stuck? Real people help you 24/7 through the AloOui Help Center. Share your order number, phone model and location, and keep the eSIM installed while we help.
