What Is an eSIM and Should You Use One?

An eSIM is a digital SIM built into your phone. Instead of inserting a plastic SIM card, you activate service by scanning a QR code or using an app (depending on the carrier and device).

Why people like eSIM

• Easier setup: no waiting for a SIM card in the mail.
• Dual SIM convenience: some phones can keep a work line and a personal line.
• Travel flexibility: it can be easier to add a travel data plan (device support varies).

What to watch out for

• Device support: not every phone supports eSIM.
• Transfer steps: moving an eSIM between phones can take a few more steps than moving a physical SIM.
• Carrier process: carriers handle eSIM activation differently.

Should you use one?

If your phone supports it and you like convenience (or you want dual SIM), eSIM is usually worth it. If you swap phones frequently and want the simplest move, a physical SIM can still be easier.
