Still unclear after looking at the chart comparison? Keep reading for a detailed explanation —
1. How They WorkWi-Fi Router:You’ll need to carry a device weighing between 100–180 grams. Moreover, you must stay within a certain range (about 3–5 meters) of the router to maintain a signal. Beyond that distance, the connection becomes unstable and may eventually drop as you move farther away.
SIMSIM Card:You’ll need to replace the SIM card originally in your phone with the new one, and some phones may require minor setup. Once done, you can use it just like your regular phone without any distance limitations.
2. Call Plans
Wi-Fi Router:No calling features are provided.
SIMSIM Card:Depending on the plan, some include calling options, giving you a local phone number, while others only offer data without voice capabilities.

3. Data Allowance
Wi-Fi Router:Currently, popular destinations in Asia such as Japan and Korea increasingly offer high-speed unlimited data plans without speed throttling. In Europe and America, there are options that provide high-speed data for the first few GB, then reduce speed afterward. This helps avoid the worry of completely losing internet access.SIMSIM Card:Data plans are very diverse, ranging from 1GB to 24GB, with a few offering full high-speed access without throttling. However, pricing varies based on the data allowance — the higher the data, the more expensive the SIM card tends to be.
4. Pros and Cons
Wi-Fi Router
Pros:
- Just like connecting to Wi-Fi at home, once abroad, simply turn on the router, enter the password to connect, and you’re good to go. It’s an easy-to-use internet tool suitable even for kids and seniors.
- Japan and Korea often offer high-speed unlimited data plans without throttling, making them great choices for those who fear running out of data. Especially for Japan and Korea SIM cards, which usually cannot be recharged — running out of data, facing throttled speeds, or disconnection without the ability to top up can be very frustrating.
- For those who like to bring laptops or tablets abroad, a Wi-Fi router is a relatively better option, offering convenient and fast connectivity.
- If you're traveling in a group of five, renting a pocket Wi-Fi router is very cost-effective, especially for those heading to Asian destinations—the daily rental rates are quite low. For example, the Shiang Yi Japan High-Speed Unlimited Data Pocket Wi-Fi, rented for five days, costs around 500+ Taiwanese dollars including setup fees. When split among the group, that’s just over 100 dollars per person for unlimited data—great value.
- Most routers have a compensation cost of several thousand NT dollars, yet the rental itself is only a few hundred. With potential compensation in the thousands, you’ll definitely be extra careful not to lose it.
- Since the Wi-Fi signal from the router has a limited range, getting separated from your travel companions without internet can be a nightmare. That’s why everyone ends up sticking very close together.
- Some SIM cards aren’t compatible with older phone models, but with a pocket Wi-Fi router, that’s not an issue at all.
Disadvantages:
- Renting one on your own is expensive, especially when traveling to Europe or America for ten-plus days—the daily rental plus setup fees really don’t add up well.
- Routers are usually kept in bags, and if they have long standby times, you can just charge them once you’re back at the hotel. But if you forget to bring it out the next day, the whole group loses internet access—and that’s just tragic.
- While returning the router at the airport is convenient, sometimes you’re so excited to get home that you leave immediately with family and forget to return the device. Then you have to make a special trip to the store or mail it back—extra hassle.
- They say using mobile data over Wi-Fi drains the battery less, but Wi-Fi routers might use more power the more people are connected simultaneously. You might have to carry a travel charger just in case—which adds even more weight.
- If you get separated from your friends and there’s no internet, finding someone who does have access can be really tricky. I’m not sure if others panic, but I definitely would.
- Most modern phones are now water-resistant, but routers aren’t. Whether you’re taking beach photos or joining Thailand’s Songkran Festival, be super careful not to let the device get wet. It’s not just about losing internet for the rest of the trip—the real trouble comes when you have to pay for the damage when you get home.
