## Frequently asked questions

**What is an eSIM?**
An eSIM (embedded SIM) is a digital SIM built into modern smartphones. It can store multiple network profiles and switch between them without swapping a physical card.

**Is my phone compatible?**
Most phones released after 2018 support eSIM: iPhone XS+, Google Pixel 3+, Samsung Galaxy S20+, and many more. The phone must also be carrier-unlocked.

**Can I keep my home number?**
Yes — eSIM-compatible phones support dual SIM. Your physical SIM handles calls and texts; the e-sim.onl eSIM handles data abroad.

**How long does the eSIM last?**
Plans have a validity period (e.g. 7, 14, or 30 days) that starts when you first connect to the network in your destination.

**What if I have a problem?**
Contact support@e-sim.onl. The team responds quickly and can re-send QR codes or assist with activation issues.
