Do I need to register my passport or IMEI number to use this eSIM?

No. This is the biggest advantage of our eSIM. Buying a physical local SIM card in Kazakhstan requires a mandatory and complicated registration process involving your passport and IIN (tax number). Cellesim eSIMs are roaming-based, which classifies you as a tourist and allows you to bypass this local bureaucracy. You can activate it instantly and avoid all paperwork and queues at the airport.
