I. Core Differences between eSIM and Local Calling Card

1. eSIM: A Convenient Solution for Digitization

eSIM (Embedded SIM) is a digitized technology that does not require a physical card and is embedded directly into the device. Users can purchase packages online and activate the network by scanning the QR code without inserting or removing a physical card. It supports multi-network switching and is ideal for short-term and cross-country travel.

2. Local calling card: the traditional localization option

A local calling card is a physical SIM card purchased by travelers upon arrival at a destination, usually provided by a local operator. Users need to insert it into their cell phone to access the local network, making it suitable for long-term trips to a single country.

While both provide network connectivity, they are used in very different scenarios and operate in very different ways.

II. Convenience Comparison: Simplification of Operating Processes

For frequent U.S. travelers, convenience is one of the top factors in choosing a network solution.

1. Convenience of eSIM

Online Purchase and Activation: There is no need to visit a physical store to purchase a package with eSIM. Users can purchase and activate the package online via their cell phone or computer, which takes only a few minutes to complete.
No need to plug and unplug the card: eSIM is directly embedded in the device without the need to replace the physical card, which is especially suitable for users with limited card slots in the device.
Seamless global switching: eSIM allows users to store multiple network configurations at the same time, suitable for frequent cross-border travelers.

2. Convenience of Local Calling Cards.

Requires offline purchase: Local phone cards usually need to be purchased at the airport or operator store at the destination, which can be time-consuming, especially if you don't speak the language.
Complicated installation and activation: After purchase, you need to manually insert the phone card and adjust the network settings of your phone, which makes the whole process cumbersome.
Limited device switching: The local phone card is applicable to a single device and cannot be switched to other devices as easily as eSIM.

Conclusion of convenience comparison

eSIM is more simplified in operation process, suitable for travelers who pursue efficiency, while local calling card requires more time and effort.

3. Cost Comparison: Who is more cost-effective?

1. Costs of eSIM

Transparent package price
: eSIM service providers offer a wide range of package choices, from small traffic to unlimited traffic, with transparent prices. For example:
- Global Package: 1GB traffic starts at around $5.
- Regional Package (e.g. Europe, Asia): 5GB traffic package is about $15-$ 20.
Avoid Hidden Fees: eSIM does not involve SIM card purchase fees, and there are no additional activation or top-up fees.
More affordable for short-term travel: For short-term travel of 1-2 weeks, the flexibility of eSIM can effectively reduce unnecessary waste.

2. Cost of local calling card

Low package price attraction
: Package prices for local calling cards are very low in some countries. For example:
- Thailand: 10GB traffic package is about $5-$ 10.
- Some European countries: 20GB traffic package is about $20.
Extra fees: You need to pay for the SIM card itself ( $3-$ 10), and some carriers may also charge an opening fee.
More economical for long term travel: If you plan to stay in a single country for several months, a local calling card may be more cost-effective.

Cost comparison conclusion

For short-term, multi-country travel, eSIM's flexibility and transparent pricing are more advantageous; however, for travelers staying in a single country for a long period of time, a local calling card may be more economical.

4. Multi-country travel: eSIM's performance is unmatched

1. eSIM's Advantages of Multi-country Traveling

Regional or Global Coverage: eSIM supports regional packages (e.g. 30 countries in Europe, 20 countries in Asia) or global packages covering multiple countries, so travelers don't need to change SIM cards frequently.
Automatic Network Switching: eSIM can automatically connect to the local operator's network according to the user's location, realizing seamless switching.
Saving Time and Effort: There is no need to re-purchase a phone card for every country you visit, reducing time and operational costs.

2. Limitations of Local Calling Cards

Single country limitation: Each calling card is limited to be used in a single country, and needs to be purchased and replaced multiple times when traveling across countries.
Potential Signal Problems: In border areas or during cross-country travel, local calling cards may have insufficient signal coverage.

Multi-country traveling comparison conclusion

eSIM performs more flexibly and efficiently in multi-country travel scenarios, and is the first choice for frequent cross-country travelers.

V. Security and Privacy Protection: Who is more assured?

1. The Security of eSIM

High security of mobile network: eSIM connects through mobile data network, avoiding the potential risk of public WiFi.
Embedded design: eSIM has no physical card, preventing data leakage due to loss or theft.
Suitable for business needs: For business people who handle sensitive data, eSIM provides higher privacy protection.

2. Security of Local Calling Cards

Privacy risk: When purchasing a calling card in certain countries, personal information such as passport may be required, increasing the possibility of privacy leakage.
Physical card loss risk: Loss of calling card may lead to account information leakage.

Conclusion of security comparison

eSIM performs better in terms of security and privacy protection, which is especially suitable for business travelers and users with higher privacy protection needs.

VI. Coverage and network quality: which is more stable?

1. Coverage of eSIM Global Coverage: eSIM is more stable.

Global Coverage: eSIM service providers cooperate with many local operators to ensure network services in more than 190 countries around the world.
Multi-Network Switching: When the signal is poor, eSIM can automatically switch to other cooperative networks to guarantee users are always online.

2. Local calling card coverage

Local Advantage: Local calling cards are provided by local operators and usually have better signal coverage in urban areas.
Cross-border limitation: Calling card coverage is limited to a single country and cannot be used after crossing the border.

Conclusion of coverage comparison

eSIM performs better in terms of global coverage and multi-network support, while local calling cards may perform better in urban areas of a single country.

VII. Explanation of Applicable Scenarios: How to Choose the Suitable Solution?

1. Suitable Scenarios for Using eSIM Scenarios for using eSIM
