[Travel Internet Guide] Introduction, advantages, disadvantages, and comparison of 4 internet data plans for overseas travel

Whether it's a SIM card, eSIM, WiFi Egg or roaming data, there are different options to choose from. When deciding which network option to use, you can first consider the following factors.

1. Number of travel days

For short trips of 1 to 3 days, or spontaneous trips, choosing an eSIM with a daily data allowance and roaming data is more flexible and convenient. For trips of 5 days or more, consider purchasing a SIM card for the corresponding number of days. For longer trips, choose an unlimited data SIM card or a WiFi egg.

2. Number of countries visited

If you are only traveling to one country, you can purchase a local SIM card, eSIM, or activate data roaming service, but SIM cards or eSIMs are usually cheaper than data roaming services. If you are traveling to multiple countries, you should check whether the service areas offered by the SIM card, eSIM, or WiFi Egg are covered and choose the best option.

3. Number of data users

SIM cards, eSIMs, and data roaming are primarily for single-person use. While it's possible to share data by creating a Wi-Fi hotspot, under the FUP (Fair Usage Policy), users may face speed throttling if they consume large amounts of data in a short period. If multiple people are traveling together and are unlikely to separate, unlimited data sharing via a Wi-Fi egg is the most cost-effective option.

4. Equipment compatibility

Since SIM cards require a SIM card eject tool to replace them, users need to check if their device has a dual SIM card slot design. Those with a single SIM card slot should keep their original SIM card safe after changing cards. While eSIMs do not require a card change, not all phones support eSIMs; device compatibility should be checked before purchasing.

5. Data traffic requirements

While each data plan offers a data allowance option, it's advisable to consider your estimated data usage during your trip and your daily internet needs when making a purchase decision to select the most suitable plan. If your data usage is extremely high, you can choose an unlimited data plan; if your needs are low, you can consider a plan with 1 to 2GB per day to save money.

6. Is a call required?

Since most internet plans only include data traffic and not talk time, if you need to make phone calls while traveling, you can consider using a data roaming service or a SIM card with calling capabilities. If you can make calls via the internet, then there's no need to worry.

7. Budget

Different options have their own advantages and disadvantages. For example, data roaming services can be used immediately after purchase without changing the SIM card, but they are more expensive; eSIMs are affordable and convenient, but some devices do not support them; SIM cards are cheap, but you need to open the card slot to replace the card. Users can make the appropriate choice based on their budget.

A traditional SIM card is a small chip data card that usually has a fixed term of use. It supports calls and data, and users can contact their mobile carrier to purchase additional services.
