Install at home, on Wi-Fi
Installation needs an internet connection, and you may not have one when you land. Installing does NOT start your plan - the clock only starts when the eSIM connects to a network at your destination.
The common flow
- 01Open your QR codeFind it in your eSIM list or in your purchase e-mail. The easiest route is to open it on a second screen - a computer, a tablet, or a printout - since a phone cannot scan a code on its own display.
- 02Start adding an eSIM in SettingsiPhone: Settings > Cellular > Add eSIM. Samsung: Settings > Connections > SIM manager > Add eSIM. Pixel: Settings > Network & internet > SIMs > Add SIM.
- 03Scan the codeThe profile downloads as soon as the camera sees the QR code. If scanning is not possible, enter the activation details from your e-mail manually.
- 04Name the lineGive it a recognisable label such as "Penyu". Switching between two lines is far easier when you can tell them apart.
- 05Choose the data lineYour phone asks which line should carry data: choose the Penyu line. Leave your own number selected for calls and SMS.
- 06Turn on data roamingTurn "Data Roaming" ON for the Penyu line ONLY. The eSIM runs on a foreign carrier's network, so nothing works while it is off. Keep roaming OFF on your own line - that is the one that generates the bill.
Do not delete the profile
Most eSIM profiles can only be installed once. A deleted profile usually cannot be restored, so leave the line in place once it is set up - simply turn it off when you are not using it.

- Turn off airplane mode and wait a couple of minutes while the phone searches for a local network.
- No signal? Toggle airplane mode on and off once.
- Still nothing? Restart the phone - this is the single most effective step.
- Double-check that roaming is off on your own line so you do not get a surprise bill.
