What is an eSIM and how does it work?
An eSIM is a downloadable carrier profile stored in compatible device hardware instead of a removable plastic card.
eSIM, plan, and profile
The eSIM is the device capability. The plan defines data allowance, validity, coverage, and provider rules. The provider profile is installed with a QR code or manual activation details. These are related but not interchangeable.
Installation is not always activation
Installing adds the profile to the device. Activation may occur on installation, on first connection to a supported network, or under another package rule. Read the selected package instructions before installing early.
Using dual SIM while travelling
Many phones let you keep the home line for calls and texts while assigning mobile data to the travel eSIM. Review roaming and data-switching settings to avoid unexpected home-carrier charges.
A safe setup sequence
Confirm compatibility and carrier unlock, buy the correct destination package, keep the protected order page, install from a trusted connection, label the new line, choose it for mobile data, follow roaming instructions, and test before leaving Wi-Fi.
Next step
Review the destination, allowance, validity, coverage, and server-confirmed price before paying. Provider provisioning begins only after Stripe confirms payment.
