Bang for your buck
I purchased it in advance through the app , and by simply following the instructions,the installation was very easy.
I was able to connect immediately after arriving,which was extremely convenient!
There was no need to swap SIM cards or deal with complicated settings,so even as a first-time eSIM user,I felt confident using it.
I traveled not only in Taipei but also to other cities,and the connection remained stable,allowing me to use map and transportation apps without any problems.
The price was reasonable,and thanks to the easy setup and great usability, plan to use World eSIM again on my next overseas trip!

The setup was easy by simply following the instructions, and it worked comfortably throughout the trip.
I often forgot to return the Wi-Fi device after coming back, so it was great not having to deal with that.
I will definitely choose eSIM again next time.

An eSIM is essential for studying abroad!
I have a 30-day plan, so I purchase and install a new one each month.
I use my phone’s hotspot when working on my laptop for classes, so having an eSIM is essential.
I occasionally travel to the UK and Spain, and I simply purchase a plan through the app each time and use my smartphone locally.
When I return to Japan, I also plan to purchase a Japan plan and continue using it

It was wonderful experience!
I traveled to France, Switzerland, and Italy, and was able to use mobile data in all countries with just one eSIM, making the trip very comfortable.
Since I use map applications a lot, I chose the unlimited data plan.
Being able to use data without worrying about limits is highly recommended!

World eSIM をご利用いただき、誠にありがとうございます。 このたびは、ベトナム・ハノイでのご利用において、インターネットや WiFi通信 が安定せず、多大なご不便とご不満をおかけしましたこと、心よりお詫び申し上げます。 長年弊社のモバイルWi-Fiレンタルをご利用いただき、信頼して初めて eSIM として World eSIM をお選びいただいたにもかかわらず、空港や市内、屋内施設、移動中においても十分な通信品質をご提供できなかった点、またカスタマーサポートの対応が遅れた点につきまして、重ねてお詫び申し上げます。 ご指摘のとおり、国や地域によっては現地通信事業者やエリア特性の影響を受け、3G接続や圏外となる場合がございます。 しかしながら、そのような制限や注意点を事前に分かりやすくご案内できていなかったこと、またお問い合わせ時に安心してご相談いただける体制が十分でなかったことは、弊社の課題であると真摯に受け止めております。 返金対応につきましても、お客様のお気持ちに十分寄り添えなかった点を重く受け止め、今後は World eSIM の提供条件、返金ルール、サポート体制を含め、eSIM を利用した海外インターネット環境全体の見直しと改善に努めてまいります。 今回いただいた具体的なご意見は、今後ベトナムを含む各国での WiFi通信 品質や商品設計、サポート品質向上のための重要な参考とさせていただきます。 このたびは貴重なお時間を割いて率直なご意見をお寄せいただき、誠にありがとうございました。 今後はより安心してご利用いただける World eSIM を目指し、サービス改善を重ねてまいります。
