No eSIM? Take a SIM card
Older handsets and a few India-bought models have no eSIM slot at all. The same plan ships to your address as a physical SIM before you fly, and works the same way once you land.


OLYSIM offers affordable international eSIM plans for instant 4G/5G connectivity in over 150 countries, with easy installation via QR codes.

Buy the plan, scan the QR code that lands in your email, and switch the line on after you arrive. Install it on wi-fi before you fly - the data only starts counting once you connect abroad.

A four-day work trip and three weeks with family need very different plans, so you choose the data and the days for Asia Max. Around 3GB covers a week of maps, messaging and a daily scroll; 10GB carries a fortnight with video calls home.
Your QR code arrives by email seconds after payment. Scan it at home on wi-fi, and the Asia Max line comes alive on its own once you land and switch it on.
Stuck on the install, or the line will not attach after landing? Message us and a person replies, whatever the hour is where you are.
Phones from the iPhone XS onward, and most Android flagships since 2019, carry an eSIM slot alongside the usual tray. Adding a plan writes it to that slot, and the SIM you use every day stays where it is.
Scanning the code from your email writes the plan onto that handset. It installs once and stays there, so scan it on the phone you are actually travelling with.
