A SIM card (Subscriber Identity Module) is a small chip that stores your phone number and carrier information, connecting your phone to your mobile service. An eSIM is an embedded digital version built into your phone that can be programmed remotely without a physical card.
How This Applies to Vouch Mobile
Vouch Mobile offers both physical SIM cards and eSIM activation.

Both options get you connected to AT&T's network quickly, with eSIM activation often completing in minutes.
