Common Questions
What is an eSIM and how does it work?
An eSIM is a digital SIM card built into your phone—no physical card needed. Activate it instantly via QR code or app, connect to local networks abroad, and avoid expensive roaming fees. Perfect for U.S. travelers!
Is my phone compatible with eSIM?
Most modern iPhones (XS and newer), Google Pixels (3+), Samsung Galaxies (S20+), and many others support eSIM. Check in Settings > Cellular/Mobile Data > Add Cellular Plan. If you see the option, you're good to go!
Which eSIM provider should I choose?
We recommend Saily as our #1 pick for most users (easy setup, security features, 200+ countries). For budget: Airalo. For unlimited: Holafly. For business/premium: Ubigi. Head to our Compare page for the latest deals!
Troubleshooting: eSIM not working after activation
1. Ensure your phone is unlocked and eSIM-compatible.
2. Restart your device after scanning the QR code.
3. Turn on Data Roaming for the eSIM line.
4. Disable any VPN/conflicting apps temporarily.
5. Contact the provider's support (e.g., Saily has 24/7 live chat). Still stuck? Email us!
