Check eSIM compatibility and carrier unlock status to avoid last‑minute setup issues.

Turn off data roaming on your primary line
Avoid surprise charges by disabling roaming on your physical SIM (or main eSIM) and leaving it for voice/SMS only.

Travel eSIM FAQs (quick answers)
Common questions travelers ask before switching to an eSIM.
When should I activate my eSIM?
Install it anytime, but activate right before departure or when you land—depending on your plan. If you’re unsure, activate on stable Wi‑Fi.
Will my phone number change?
Your OneTap.Global eSIM is for data. You can keep your primary SIM active for your usual number while using the eSIM for internet.
Can I use hotspot/tethering?
Most devices support hotspot with eSIM data. If you rely on tethering for work, test it once before your trip.
What if I run out of data?
Choose a larger plan upfront or top up by purchasing another plan in the Shop.
Do I need Wi‑Fi to install?
Yes—installation requires internet. Download your QR code and keep it accessible offline in case you need to reinstall.
Is eSIM secure?
It’s generally more secure than public Wi‑Fi. Still, use a strong passcode, enable device find features, and avoid unknown hotspots for sensitive logins.
