Holafly

Founded in Spain, Holafly specializes in regional eSIM packages with unlimited data allowances for travelers crossing multiple countries. The plans target Europe, Asia, and the Americas, prioritizing capacity over cost for users who need heavy data usage.

You buy directly from its website or app without intermediaries, and support is available round-the-clock. Plans typically cost more than limited-data competitors but offer heavier usage buffers for streaming, video calls, and navigation.
