Preparing for an overseas trip is a lot of work! In addition to a passport, plane ticket, and local currency, you'll also need a smartphone to do research and use maps while you're there!

SIMはどのタイミングで設定すればいいですか?

  • eSIMの設定には、WiFiへの接続が必須となります。旅行の出発前にeSIMのインストールとアクティベーションをするのが理想的です。  
  • eSIMのアクティベーションは目的地へ着いてからでも行えますが、インストール作業にはWi-Fi接続が必要ですのでご注意ください。

プランのカウント方法を教えてください。

利用開始時間から24時間で1日とカウントするのではなく、現地回線に接続した時点からその日の23:59(台湾時間)までを1日としてカウントします。 時間の基準はUTC+8となります。日本時間ではございませんのでご注意ください。

日本で設定中に回線がオンになってしまったのですが利用開始となりますか?

  • 弊社eSIM/SIMは現地にて現地回線と接続されたところからの利用開始となります。日本国内にて回線をオンにしていただいても利用開始となりませんのでご安心くださいませ。

テザリングはできますか?

  • 可能です。(端末に依存するため動作保証は行っておりません。)

期間の延長や通信容量のチャージはできますか?

  • 延長や追加(チャージ)はできません。トランジット(乗継)をご利用の方は現地Wi-Fiが繋がらない事もあるため、経由地のeSIMもご購入頂くことをおすすめいたします。

SIMカードとeSIMを同時に使用できますか?

  • はい。通話とSMSの送受信にはSIMプラン、データ通信には eSIMプランを使用するという形で、2つのSIMを使いわけることができます。そのために必要な設定を端末で行えば、両方を同時に使用することができます。
  • ただ、SIMプランの設定を有効にしてしまうと、通話やSMSの送受信を行った際に国際ローミング料金が発生することがありますので、注意が必要です。

How many times can I use an eSIM?

  • An eSIM can only be activated on one device and cannot currently be transferred to another device. You cannot scan the same QR code on two devices, but some eSIM plans allow for tethering.

Can I use a SIM card and an eSIM at the same time?

  • Yes, you can use two SIMs at the same time: one for calls and SMS and one for data, using a SIM plan and an eSIM plan.
  • However, please be aware that once you enable the SIM plan settings, you may incur international roaming charges when making calls or sending and receiving SMS.

When should I remove my eSIM?

  • If you want to continue using the eSIM, do not delete it. Once you delete the eSIM, you will no longer be able to read the QR code and it cannot be reissued.
  • If your eSIM doesn't work for some reason, don't delete it.
  • If your eSIM isn't working, please contact our customer support and we'll help you identify and resolve the issue.
