My recent trip covered a lot of ground in the Tohoku region. Aside from a very brief moment on the second or third day, the connection speed and stability were fantastic throughout the rest of the trip.
網路很慢
您好,非常抱歉這次的網速表現沒能達到您的期待,感謝您留下寶貴的評價。
我們剛剛查詢了客服系統,並未發現您的諮詢紀錄。其實若您在旅途中遇到網速異常,都可以第一時間聯繫我們,讓我們協助您排除狀況喔!
針對您提到的網速偏慢問題,建議您在接下來的旅程中可以透過調整手機設定來改善。
麻煩您嘗試以下步驟:
1. 將手機的 APN 設定更改為:m-air.jp
2. 將手機的**「數據漫遊」功能關閉**
完成上述設定後,通常能幫助網路連線恢復正常。
若您目前仍在旅途中,或後續還有任何設定上的疑問,都非常歡迎您隨時透過客服管道與我們聯繫,我們將竭誠為您服務。
希望能有機會再次為您提供更好的體驗!
網速緩慢且不穩,尤其是原宿、澀谷、銀座三個鬧區會出現連google map都打不開的狀況,同行友人使用電信漫遊一切正常。自己用過多次其他原生esim,在日本沒遇過這個問題。
但客服購買前、安裝協助都相當客氣。

おすすめ
新千歳空港に到着後、すぐに電波を掴みました。今回の旅程(札幌、小樽、積丹町、黄金岬、島武意海岸、神威岬、いわない高原、神仙沼、ニセコ、京極町での乗馬、洞爺湖、室蘭地球岬、登別地獄谷、支笏湖)では、神仙沼の遊歩道の奥深く以外、すべて圏内でした。Googleマップ、SNS、Geminiなどの通常使用は全く問題ありません。
通信速度に関しては、市街地でも動画再生時に少しカクつくことがありましたが、旅行中は動画をほとんど見ないため、この価格を考えれば十分納得できるレベルです。
また、DHAのeSIMは日本の三大キャリアのネイティブ回線を利用しているため、中国等へのデータ流出の心配がなく、セキュリティの面で非常に安心できました。
台湾の通信会社のローミング(使い放題)と比較しても費用を大幅に抑えられるので、とてもおすすめできる商品です。
