Bang for your buck

I used World eSIM during my trip to Taiwan.
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!

I always used to rent portable Wi-Fi for overseas travel, but this was my first time using an eSIM and it was absolutely the right choice!
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 am using World eSIM while studying abroad in France.
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!

This time, I purchased a Europe multi-country plan for the first time.
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 をご利用いただきまして、誠にありがとうございます。 このたびは、ヨーロッパでのご旅行に際し、World eSIM の eSIM をリピートでご利用いただき、便利に快適なインターネット環境をご体験いただけたとのこと、大変うれしく拝読いたしました。 SIMカードの入れ替え不要で空港での WiFiレンタル待ちもなく、スムーズにインターネット接続ができる点は、World eSIM の大きな特長です。 快適な検索や通信速度もお楽しみいただけたとのことで、私たちも非常に励みになります。 今後の海外旅行でも、ぜひ World eSIM をご利用いただき、快適な WiFi通信とインターネット環境をお楽しみください。 またのご利用を心よりお待ちしております。

ベトナムでは繋がり難い

ベトナムのハノイで使用。長年海外行く度に使用してたこの会社のモバイルWi-Fiのレンタルから初esimへ。この会社なら間違いないと思い購入。全くもって使えない。空港では3G回線に。屋内レストラン、ホテル内では圏外。タクシー移動中は3Gになったりならなかったり。カスタマーサービスにメール連絡するも、レスポンスが悪い。結局、全く使えない旨を伝えて〈日割り〉で返金。使えない旨を消費者が早い段階で伝え、無料キャンセル料になる代金も支払っているんだから、全額返金してくれたらまだ次回使用するつもりだったが、二度と使わない。会社もどうやら部署によって契約している様なのでベトナムでは使用を控える様促したい。

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。
