Quick answers
For many solo travelers with an unlocked, compatible phone, eSIM is the simplest option because it does not require physical pickup. Travelers whose phone is not compatible often prefer a physical SIM, while groups usually benefit from pocket Wi-Fi.
Check your phone settings or manufacturer specifications for eSIM support, and confirm with your home carrier whether the phone is unlocked. Both eSIM and physical SIM depend on this, so it is worth checking before you buy.
An eSIM or physical SIM is normally used on one phone. Pocket Wi-Fi is designed to connect several devices at once, which is why it is often a good fit for families or groups traveling together.
Prices, data allowances, and plan conditions can change. Always confirm the current details on the provider's official website before booking.
