The Smart Way for
British Travelers
to Stay Connected Abroad
Avoid expensive roaming charges from EE, O2, or Vodafone UK outside the EU. Get instant 5G/4G internet anywhere with Cellesim eSIM.
💳 Pay securely with UK cards or Apple Pay. Your UK SIM stays active for WhatsApp and Bank OTP verification (Barclays, HSBC, Monzo).
Installieren Sie die eSIM vor der Abreise über WLAN. Prüfen Sie den Gültigkeitsbeginn Ihres Pakets; Installation und Aktivierung sind nicht immer gleich. Die Geschwindigkeit hängt von Standort, Gerät und Paket ab.
Why British Travelers Switch to eSIM
Before Boarding
Vergleichen Sie Datenvolumen, Gültigkeit und Gesamtpreis in der Paketliste. Prüfen Sie vor dem Kauf Abdeckung, Hotspot-Nutzung und Fair-Use-Bedingungen.
Local UK carriers often have hidden speed caps or small fair usage limits while abroad
Don't waste holiday time in airport queues hunting for physical local SIM cards and showing your passport
Pocket Wi-Fi is an extra device to charge. Cellesim is 100% digital on your existing phone
