eSIM Data Calculator

Download offline maps — Save Google Maps or Apple Maps regions over WiFi before you leave. Navigation works offline and saves significant data.

Disable background refresh — Turn off background app refresh in your phone settings. Apps like social media and email consume data even when you're not using them.

Lower video quality — Set YouTube and Netflix to standard definition (480p) on mobile. You'll barely notice the difference on a small screen but save up to 75% on data.

Use WiFi for heavy tasks — Download content, sync photos, make video calls, and update apps over hotel or cafe WiFi. Save your mobile data for when you're out exploring.

Monitor your usage — Check your phone's built-in data usage tracker daily. On iPhone, go to Settings > Cellular. On Android, Settings > Network > Data usage.
