When traveling internationally, you’ll need to decide whether to keep your regular phone number active or turn it off to avoid carrier fees for calls and texts. If you plan to use Superhero eSIM for your data needs, it’s best to install your eSIM while connected to a strong internet source before you leave. If you choose to keep your primary SIM active, ensure your carrier won’t place you on a travel plan with daily fees.

To avoid roaming charges, activate your data package right before you travel. For some, this means disabling roaming on the primary SIM while keeping the number active; for others, it might involve turning off the primary SIM completely. Once you arrive at your destination, complete the activation of your eSIM package to start using your prepaid data.
