How Penyu works
What an eSIM is, which plan to pick, how much data you need, how to install it and what to do when something goes wrong - in plain language.
The basics
What is an eSIM and how does it work?
A SIM card built into your phone. What it is, how it differs from a physical SIM and from roaming, and which phones support it.
ReadWhich eSIM plan should I choose?
Country or region, how many days, how many GB, is unlimited worth it? A short decision guide so you get it right the first time.
ReadHow much data do I need?
Enter your average daily usage from your phone and we will work out your daily GB, your trip total and the plan size to buy.
ReadBuying
How do I buy an eSIM?
The whole flow from picking a country to paying: finding a plan, quantity, checkout security, invoices and the refund rule.
ReadCan I gift an eSIM to someone else?
Yes. You pay, and the eSIM opens straight in the recipient's account. You can also keep covering their later top-ups.
ReadCan I buy eSIMs in bulk?
Yes. Buy several of the same plan in one order; each one is delivered as its own eSIM line.
