About ZESIM

The eSIM provider built for the modern traveler

We're not another marketplace. We're the provider.

ZESIM was built because we were tired of eSIM marketplaces that aggregate plans from providers with inconsistent coverage, slow speeds, and hidden fair usage policies. We own our network infrastructure, partner directly with Tier-1 carriers in every country, and deliver the best possible experience at the lowest possible price.

5G in 80+ Countries

We include 5G as standard where others charge extra. Our direct carrier partnerships mean faster speeds everywhere.

No Fair Usage Throttling

Our unlimited plans are truly unlimited. No speed caps after 2GB, no "fair usage" surprises, no hidden limits.

Up to 70% Cheaper

By cutting out middlemen and aggregators, we pass the savings directly to you. Better plans, lower prices.

Instant QR Delivery

No app download required. Purchase and receive your QR code instantly. Scan and connect in under 60 seconds.

200+ Countries

Coverage on every continent. Direct Tier-1 carrier connections mean reliable service in popular and remote destinations alike.

Hotspot on Every Plan

Share your connection with your laptop, tablet, or travel companions. Hotspot is included on all plans.
