Jetpac

Jetpac differentiates itself by bundling voice calling capabilities directly into its eSIM offering. Beyond standard mobile data, the app allows travelers to purchase outbound call packs, combining voice and data into a single service rather than treating them as separate add-ons.

This approach suits travelers who need to make phone calls while abroad, whether for contacting businesses, hotels, or friends at home. Many competitors focus primarily on data, leaving calling as an afterthought or expensive add-on, so Jetpac's integrated voice capability appeals to users who don't want to be tethered to WiFi or messaging apps for all communication.
