Better data plan options

This makes it easy to find deals that may not be available at airport kiosks.
With more options available, you can purchase a data plan that suits your needs without the pressure of making a quick decision at a busy airport or store.
Instead of going for a SIM option, you can make your trip even easier by buying an eSIM alternative like Holafly. An eSIM eliminates the need for swapping cards for activation.
You can simply buy a data plan and activate it through your phone’s settings.
Peace of mind
Buying your SIM card before traveling ultimately means you won’t have to worry about staying connected once you enter the country.
Knowing you have your communications and connectivity issues sorted out before you touch down makes your trip less stressful.
It also ensures you never have to connect to risky public WiFi during your travels, meaning you can rest easy knowing your browsing and data is private.
