Real Complaints
- Airalo: Reddit reports of refund refusals and slow support responses; some 2025/26 account security complaints — pay with a virtual card
- Unknown cheap sellers (Shopee etc.): Recurring refund difficulty complaints — cheap + obscure is a risky combo
Before You Buy Checklist
- Screenshot the refund terms at checkout
- Don't install until you're sure (installation often voids "unactivated" refunds)
- Test on home Wi-Fi before departure — if it fails, you're inside every refund window
- Pay with a virtual/disposable card for extra protection
First-Timer Recommendation
Nervous about eSIM? Saily's 30-day refund on unactivated plans makes it low-risk, or go with Yesim's 100% refund guarantee.
