Trip.com Japan eSIM user reviews

It seems that Trip.com eSIM has done pretty good in multiple aspects. Here are some verfied reviews selected to help you have a glimpse of what it feels like while using Trip.cpm eSIM in Japan.

Most people think the speed connection is quite fast and stable.

"The connection is smooth immediately after the plane is off, and the use is not stuck at all. It is worth buying 👍 I will definitely buy it again next time I go abroad. It is really convenient ❤️"
"I used it and the internet is very fast. Use all the time I go, there is no interruption, no traffic jam, but before opening the roaming and bought a SIM to wear. When I tried the esim, it's very good."
"This is my first time to use eSIM. I am impressed by the ease of setting up. The speed is awesome. I got stable 5G in the city and reached 300 MBs easily. I cannot do many Speedtest because of the daily cap. I definitely will buy the same esim again for next trip."

Which is Better in Japan? eSIM,SIM card or Wi-Fi routers?

SIM cards offer the convenience of no need to worry about charging like Wi-Fi routers, and they take up very little space in your luggage. There are plenty of plans to choose from, but they do come with drawbacks such as a complex setup process and the requirement for a SIM-free smartphone.

Wi-Fi routers are easy to set up once you arrive and can be shared with multiple people or devices. However, they can require extra charging and the hassle of managing and handing over the device. eSIM, on the other hand, doesn't need a physical card, so there's no risk of loss or damage. The setup is relatively simple, but it’s only available on compatible smartphones.

Below is a table that compares the features and considerations of the three options.

FeatureWarning
eSIMNo risk of loss or damage; No need to carry around; Easy to set up; Can be used upon arrivalPhone number may not be used; Limited number of smartphones can be used
SIM cardNot bulky; Many purchase plans availableNeed pin to swap cards
Wi-Fi routerCan be used immediately upon arrival; Can be shared by many people; Can be connected to many devicesCan be troublesome to carry around; Difficult in receiving and delivering

Conclusion

eSIM offers unmatched convenience and flexibility for travelers with compatible phones, making it a top choice for tech enthusiasts or those seeking a hassle-free setup without the need to swap SIM cards.
SIM cards are a budget-friendly option for short trips, suitable for those who don’t mind physically replacing their SIM and managing limited data plans.
Wi-Fi routers are ideal for families, groups, or heavy data users who need to connect multiple devices. However, they come with the added cost and inconvenience of carrying an extra device.

You can choose the most suitable option based on your real needs.

Central Tokyo Tokyo|2.87km from city center
The room was a bit dated, but it was fully equipped. Its biggest advantage is the downtown location, making it incredibly convenient to get around, with easy subway access to everywhere. The breakfast was fantastic, but unfortunately, we couldn't see the peak of Mount Fuji during our stay.

The environment is very clean, and the bedding is super comfortable. It's really convenient to pick up toiletries downstairs. Although the room is small, it has everything you need. We chose this hotel because my partner smokes, and it's one of the few smoking rooms available in Tokyo. The location is, of course, incredibly convenient. We booked a car for 10 days, but didn't use it at all for two days because we were shopping in Ginza. We paid a higher price than usual, but the location and comfort are excellent, and the room is clean. I'll definitely stay here again.

Ginza/Tsukiji Tokyo|0.66km from city center
I really like these luxury hotels that, despite being old, are still well-maintained. I booked a tower room, and after check-in, it was quite a walk to get there, but a staff member helped with my luggage and brought it to the room. I've stayed at the Imperial Hotel Osaka before, and the service and decor style are consistently similar. On the second day, a floor lamp in my room was accidentally damaged, but it was quickly replaced with a new one, and I wasn't charged for it. The breakfast options are extensive; I only tried the buffet and the Western set menu, and both were very satisfying.

We had a wonderful family stay at Tokyo Dome Hotel. The location was perfect — right next to Tokyo Dome City with plenty of entertainment, food options, and easy access to the subway. The rooms were clean, comfortable, and offered beautiful city views. The staff were exceptionally friendly and helpful throughout our stay, making check-in smooth and ensuring we had everything we needed. Our child enjoyed the nearby attractions, and it made exploring Tokyo so convenient for the whole family. Overall, a great experience and a hotel we would happily return to on our next trip to Tokyo. Highly recommended for families!

Tokyo Tower Area Tokyo|2.41km from city center
It's a good hotel with an excellent location and convenient transportation. The only downside was finding out upon arrival that an additional 15,000 yen was required for a tower view room! We ended up paying the extra fee to upgrade anyway. The front desk staff were professional but lacked a bit of warmth, which could be improved.

Ginza/Tsukiji Tokyo|0.29km from city center
The location was very convenient and really close to major metro lines . The view from the high floor was nice especially for watching the sunset. As others have posted the room was really small. If you stay more then two days you will need to close your suitcase and organize your things when housekeeping comes. Otherwise they wouldn’t be able to get very far into the room. The water filer and ice machine on the room floor was really helpful especially when going out for the day with the July heat. The room was not so clean. When I went to use the humidifier it was covered in dust which set off my allergies. Also one of the walls had water damage.There was also a badly done patch on the corner of the wall. The lack of more than one outlet next the bed was annoying, especially when the provided charger didn’t work. One of the reasons I booked was the “lounge”. It was quite disappointing. It was loud in the room and it was right next to a smoking room. The available beverages were not that great. I don’t drink coffee and the juice was so sugary. One more thing that was a little annoying, but not necessarily a negative was housekeeping giving me new towels everyday even though I never put used towels outside with my trashcan in the morning. I stayed less than a week so I was fine using the two provided towels, so I had two bags of new towels sitting on my floor until housekeeping cleaned my room.

Ginza/Tsukiji Tokyo|0.44km from city center
This hotel *absolutely* won't let guests sleep! The hotel *insists* on room cleaning between 10:00 AM and 1:30 PM. If you don't comply, they'll call your room repeatedly and staff will even come knocking on your door to hassle you! They simply won't let you get any rest! I work nights and need to sleep past midday. However, the staff here showed *no understanding* whatsoever! After decades of staying in hotels, this is the *first time* I've encountered such an issue! That 'Do Not Disturb' sign (pictured in Fig 3) is completely useless, as they *insist* on coming in to inspect the room themselves! If you cannot leave your room before noon for them to clean, *do not* choose this hotel! What's more, right from check-in, I found the hotel wasn't clean! There were numerous unidentified items on the floor – I would have done a better job cleaning it myself!

Tokyo Tower Area Tokyo|2.05km from city center
This hotel, built in 1964, is truly iconic with a very luxurious exterior, and it's just a five-minute walk from Tokyo Tower. Although the interiors have been renovated, you can clearly tell the facilities are a bit dated, especially the bathroom. It's much smaller than the room and only has a bathtub, no separate shower, which I wasn't too fond of. We were upgraded to a room with a Tokyo Tower view, and opening the curtains to that beautiful scenery immediately brightened my mood. However, to be honest, aside from being close to Tokyo Tower, the public transport links aren't very convenient. It's about a 7-8 minute walk to the nearest subway station and a 15-minute walk to the nearest JR station.

My repeated stay... I love the coziness of this room, nicely tugged away from the bustling main of Ginza. Nice hospitality... Good service led by Hosoya san, who has been really helpful in queries and assistance when needed. Self-serve laundry and dryer service, 2 units each, which gets really busy with guests. There's a common guest area we can help ourselves to coffee, and guests are okay to consume their takeout or packed food from outside. All else can't find any fault...and plus point room window can be opened for slight ventilation.

Shinagawa Tokyo|5.46km from city center
This was my second stay at a Prince Hotel. My first experience was at the Onarimon branch near Tokyo Tower, which left a great impression. I arrived in Tokyo for a business trip past 8 PM. After dinner with a client at a small restaurant near Shinagawa, I checked in around 10 PM. Room 52719 offered a night view, though I was too late to fully take it in. The next morning, I woke up to a clear view of Tokyo Tower. The hotel complex consists of several buildings: the East Tower, Main Tower, North Tower, and the Annex. The Main Tower's breakfast area was very crowded. The Annex, however, was a bit less congested and offered a convenient direct passage to Shinagawa Station. The room facilities were a bit dated. It had a bathtub, a refrigerator, and an ice bucket, but I was too late to make use of them. The next morning, I had to be at my client's by 9:30 AM, so after a quick breakfast, I checked my luggage and rushed off. Upon returning to retrieve my bags, I made use of the lounge area to charge my phone and catch up on some emails before heading straight to the airport. Location: Directly across from Shinagawa Station's West Exit. Wi-Fi: Excellent speed.

Shinagawa Tokyo|4.74km from city center
The room was bright and of a good size. It came with Mikimoto toiletries, and I even took the unused ones home. The pillows deserve a special mention, as they were the most comfortable I've ever slept on in a hotel. The hotel also features its own beautiful garden courtyard, which is perfect for a relaxing half-hour stroll. Transportation is very convenient. A shuttle bus provides direct service to Meguro Station, and from there, the Yamanote Line offers excellent access to Shibuya, Harajuku, and Shinjuku. Getting to Yokohama is also straightforward. Taxis are readily available 24/7 right outside the hotel entrance. A taxi ride to Haneda Airport cost around ¥3,000-¥4,000, which I considered a reasonable price. The only minor issue was that the in-room coffee machine wasn't very clean, so I'd recommend checking it thoroughly before use.

Location: Exiting Shibuya station, there's ongoing construction, so you might need a moment to find your bearings, but it's not difficult to locate, situated directly opposite Tokyo Plaza. Facilities: The hotel is very modern, featuring a spacious lobby and relatively new room amenities. It comes equipped with a full set of L'Occitane toiletries, and as a delightful surprise, we also received an SK-II morning and evening skincare sample set upon check-in. Environment: The view from the window is absolutely stunning, both by day and night. I snapped a quick photo, and it honestly looks like a perfect backdrop for a blogger's video – haha! Service: The front desk check-in service was excellent. However, for a hotel of this standard, the breakfast quality felt a bit basic, with limited options. Coffee and tea had to be brought by staff – I'm not sure if that was meant to make guests feel more pampered or exclusive. Overall, the breakfast was just average, but everything else was great.

They explained the hotel amenities and menu as if we were just catching up with old friends.

The hotel's location is excellent; it's right above Tokyo Station, next to the Marunouchi entrance. This made catching the Shinkansen the next day incredibly convenient, and even chartered cars could pull right up to the entrance. The breakfast was absolutely delicious; the unagi (eel) rice was better than what you'd find outside, and the entire meal was exquisitely prepared. The service was also exceptionally thoughtful – the housekeeping staff even straightened my doll when they cleaned the room during the day while I was out.

I stayed for four nights. The room was indeed small, but it had everything I needed, which is probably common for Tokyo. The view from the window was nice, overlooking a main road in Tokyo. The soundproofing was excellent; once the door was closed, I barely heard any noise. Breakfast was the same every day, quite Western, with no meat buns, egg fried rice, or raw eggs. The hotel staff were all very friendly. The location was great, a 10-minute walk to Tokyo Tower, and there were two or three subway stations nearby. Although not directly below the hotel, they weren't far, and taking the subway in Tokyo is very convenient. I would definitely consider staying here again if I return; it offers great value for money.

This time, I stayed at The Peninsula Tokyo with my daughter for a vacation and felt happy and satisfied, especially with the attentive facilities and staff. Coincidentally, since our departure date fell on a weekend, the hotel specially opened the 24th-floor Peter for guests to have breakfast, allowing us to enjoy a panoramic view of the Palace in the morning. However, the meal presentation service there seemed not as attentive as in the lobby restaurant or room service. I hope to try it again next time to experience it better.
