• Data-only service: Most Airalo plans do not include a local phone number.

Holafly: eSIM International Roaming with Unlimited Data

Holafly is particularly well known for its unlimited-data eSIM travel plans. Instead of focusing primarily on small data packages, Holafly targets travelers who expect to use a significant amount of mobile data during their trip.

Pros of Holafly:

• Offers international eSIM plans covering more than 200 destinations.
• Easy to use. Simply select an unlimited data plan based on the number of days you’ll be traveling.

Cons of Holafly:

Saily: Travel eSIM App with Simple Activation

Saily is created by the NordVPN team with high security eSIM service and flexible plans, ranging from 1GB to unlimited data. It is designed around a simple app-based experience. It allows travelers to purchase and manage their international eSIM data plan through its mobile application.

• New-user-friendly, with the purchase and management processes integrated into a single app, making the overall experience more convenient.

Cons of Saily:

• Limited flexibility. If you prioritize customized short-term eSIM travel plans, Saily may not be the best choice for you.
• Some unlimited data plans offer a certain amount of high-speed data, once that allowance is used up, roaming eSIM speeds will drop to a lower level.

NPN Travel: Global eSIM Provider with Highly Affordable Rates

NPN Travel is the best eSIM for international travel, offering affordable and flexible mobile data plans for travelers. Rather than requiring travelers to purchase a large data package for every trip, NPN Travel offers different eSIM service options designed to accommodate different travel durations and data needs.

Pros of NPN Travel:

• Affordable prices: users can freely choose international eSIM plans that offer exceptional value for the money.
• Flexible plan options: if you’re only traveling for a few days, NPN Travel is the best eSIM for international travel choice.

• Cheap international eSIM: Compared to other eSIM, NPN Travel offers the most affordable plans.

Cons of NPN Travel:

• This eSIM offers data plans only. If you need a local phone number to make calls or send text messages, this eSIM provider may not be right for you.
• eSIM network performance may vary depending on your destination and local network conditions.

Roamless: International eSIM Plan with One-Time Installation

Roamless takes a slightly different approach from traditional prepaid international eSIM. Instead of requiring travelers to purchase and install a completely new eSIM for every destination, Roamless allows users to keep one eSIM travel across different countries.

Pro of Roamless:

• High Convenience: If you travel abroad several times a year, having an international travel eSIM that works across multiple destinations saves you the hassle of repeatedly installing new eSIM profiles.
• Flexible Pay-as-You-Go Model: There’s no need to sign up for a large-capacity data eSIM plan in advance, you can purchase data anytime.

Cons of Roamless:

The price is relatively high. For travelers staying in a single country for an extended period and using a large amount of data, a flat-rate local or regional travel eSIM plan may offer better value for money.

Comparing International eSIM Plans and Pricing
