When does my plan start?
It depends on the plan: 9 plans start when your phone first connects at your destination, and 1 starts when you install it. Each plan says which.
Why might apps show content for Hong Kong?
3 of 10 plans here send your traffic out through Hong Kong (they carry a Hong Kong IP badge), so some apps and sites may show content for Hong Kong. The other plans don’t.
Does my phone support eSIM?
Most recent iPhones, Pixels and Samsung Galaxy phones do, as long as the phone is unlocked. Use our compatibility checker before you buy.
Will I lose my WhatsApp or phone number?
No. The eSIM only adds data. Your main SIM and number stay on your phone. Tip: turn off data roaming on your home line so it doesn’t charge you abroad.
