Will this keep my WhatsApp active with my home number?

Can I use it in nearby countries too?
That depends on the plan — country plans work in that country only, while our regional and global plans cover multiple destinations.
James K. · 8 months ago
Is roaming charged extra or is it all included?
No extra roaming fees — the price you see is the price you pay.

Do I need to install it before I travel or after I arrive?
Set it up before departure. Installing needs internet, and airport Wi-Fi is not always reliable.

Can I top up the same eSIM instead of buying a new one?
Top-ups are supported on most plans — look for "Top-up supported" on the plan page.

Delivery is immediate. The QR is in your account the moment payment clears.
