Used B4travel SIM in Japan - blazing fast speeds and stable connection throughout my trip. Highly recommended!
AAlex C.Hong Kong Traveler
Alt SIM Card unlimited data is a lifesaver. Had signal even in remote parts of Australia. No more worrying about data caps.

Frequently Asked Questions

A physical SIM card needs to be inserted into your phone's SIM slot, while an eSIM is an electronic SIM that can be activated by scanning a QR code - no physical card needed. Most modern phones support eSIM.

For B4travel physical SIM cards, we recommend ordering 2-3 days before departure to ensure delivery. eSIMs can be purchased and activated instantly anytime.
