The Smart Way for
German Travelers
to Stay Connected Abroad
Avoid expensive daily roaming fees from Deutsche Telekom, Vodafone DE, or O2 outside the EU. Get instant 5G/4G internet anywhere with Cellesim eSIM.
💳 Pay securely with German cards or Apple Pay. Your German SIM stays active for WhatsApp and Bank OTP verification (Sparkasse, Deutsche Bank).
출발 전에 Wi-Fi로 eSIM을 설치하세요. 요금제 시작 조건을 확인하세요. 설치와 활성화 시점은 다를 수 있습니다. 속도는 위치, 기기, 요금제에 따라 달라집니다.
