Frequently asked questions
Short answers to the most common questions.
When does my eSIM start?
Validity starts when the eSIM first connects to a network in your destination country, not when you buy it. You can install it at home before you fly.
Does my primary number stay active?
Yes. Yuscom plans are data-only. Your primary number stays active for WhatsApp, SMS, and OTP. Just make sure mobile data is routed to the Yuscom eSIM.
How do I install an eSIM on iPhone?
iOS 17.4+ can use the one-tap install button on the installation page. Otherwise: Settings → Cellular → Add eSIM → Use QR Code, then scan the QR from your order page.
How do I install an eSIM on Android?
Open Settings → Network & internet → SIM → Add SIM / Download a SIM instead, then scan the QR or enter the SM-DP+ address and activation code manually.
I deleted my eSIM. Can I reinstall it?
Yes, as long as the profile has not been permanently removed from another device. Open My eSIMs, select the eSIM, and reuse the same activation code. If it fails, contact support.
