Should I buy my eSIM data plan before traveling or when I arrive at my destination?

You can do either, but it's best to buy and install your eSIM before you travel.
That way, you'll land with everything installed and ready to activate, so you can get online soon after your plane touches down.

If you prefer, you can also buy and activate your eSIM after arrival. It only takes a few steps to install and start browsing. Just remember that you'll need a stable internet connection (Wi-Fi or mobile data) to complete the installation.

For most travelers, setting it up in advance is the easiest way to avoid airport Wi-Fi and stay online from the moment you arrive.

Before you buy, it's worth confirming your phone can use an Ohayu eSIM. In the Ohayu app, tap the gear (Settings) icon in the top-right corner, then under Help & Support choose Device compatibility. You can also tap Check carrier lock status to make sure your phone is carrier-unlocked.

Benefits of buying your eSIM before your trip

Connect the moment you land

Skip the search for Wi-Fi or local SIM cards. Install your eSIM before you travel and switch it on when you land, so you're online soon after you arrive.

Skip airport lines and tourist markups

No need to queue at kiosks or overpay for tourist SIMs with hidden fees and additional paperwork.

Travel stress-free

Set everything up at home and enjoy peace of mind knowing your data is ready.

Your plan starts when you do

No need to worry about wasted days. For country and Unlimited plans, your eSIM's validity period begins only after activation, so every day you pay for goes toward actual use. Global subscriptions start on the day you buy them.

If you'd rather not track GB, in selected countries you can also pick an Unlimited plan, one price for your whole trip with a daily full-speed allowance. See how to buy a plan.
