Most iPhones (from iPhone XS and newer) support eSIM. To check on your device, go to Settings > Cellular (or Mobile Data) and see if you have the option to Add eSIM or Add Cellular Plan. You can also check Apple’s official device specifications or confirm that your iPhone is unlocked, as carrier-locked devices may not support eSIM usage.

Question 7

How do I install and set up an eSIM on my iOS device?

Accepted Answer

After purchasing your TNS eSIM, you’ll receive installation details via email or in the app. Make sure you have a stable internet connection, then go to Settings > Cellular > Add eSIM. Scan the QR code or follow the on-screen instructions to complete installation. Once installed, set the eSIM as your mobile data line, and it will automatically connect when you arrive at your destination.

Question 8

When does my eSIM data package expire?

Accepted Answer

Your eSIM data plan becomes active when it first connects to a supported mobile network, usually at your destination. The validity period starts from that moment—not from the purchase date.
