Reviews
“Very satisfied as a secondary device: I was surprised at how small it is, even more than I imagined. It's convenient to carry around and works great as a secondary device for calls and messages. It does take a little getting used to for operation, but I think it's perfect for those who like this size.”
“Mini smartphone that can make calls and use the internet: The iijmio SIM card worked without any issues. The speed is slow, but it is sufficient as a secondary device for calls and internet use.”
“小学生用にはコスパ良い: 小学生の子どもにキッズケータイがわりに持たせる用に購入。他の子のキッズケータイを見せてもらったら、それらよりひとまわり小さくて薄さも軽さもこっちの優勝でした。格安SIMを入れれば普通のスマホ同様、LINEや通話、GoogleファミリーリンクアプリでのGPS追跡など、なんでもできます。カメラは3つあるように見えて２つが飾りで本物のレンズは1つだけで画質は昔のガラケーに毛が生えた程度です。また容量も起動して初期設定した段階で1/3が埋まったのですぐいっぱいになりそう。また、メモリも少ないのか、LINEのトークルーム開いたりなどの動作が若干カクついてモッサリすることがあります。あと画面小さいので文字が非常に打ちづらいです。音声メッセージメインでも送信ボタンを的確に押すのがちょっと難しいレベル。画面右下の反応がやや悪いのか、LINEの画像保存するために右下の保存ボタンを押すと特に反応が悪くてイライラします。とはいえこの値段ですし、子どもに持たせてちょろっと連絡とったりする用途に限定すればコスパは良いです。”
“子供へのプレゼントに大変喜ばれました子供へのプレゼントに大変喜ばれました: 手のひらサイズのスマホ、想像以上に精巧です！Android 搭載で Wi-Fi も問題なく使え、カメラの画質も鮮明。好きなアプリを自由にダウンロードできて機能が充実しています”
“Good product. I like the feel of it.”
“This is arguably the only option for a super compact smartphone: If you've ever purchased a budget Chinese tablet, you won't be surprised by its performance. It operates similarly to a used smartphone under 10,000 yen from around the Android 10 era. It supports Japanese, but you'll need to change the language settings from the System menu in Android. The SIM compatibility includes Softbank and Rakuten on the platinum band, and if you're okay with non-platinum band, Docomo and Au should also work. Due to its small screen and lower performance, I can't recommend it for everyone, hence the ★4 rating, but for those with specific needs, it’s a fantastic match. My only personal complaints are the lack of a care charging feature and no headphone jack (I wanted to use it as a high-performance music player with the charging cable plugged in).”
“Convenient to carry: It's small and lightweight, making it easy to carry around, but it's fine for phone calls only. Typing emails or using LINE is difficult and hard to see.”
“docomoのVoLTEに対応している: CUBOT POCKET をdocomo のSIMで使用してきたのですが、4月から電話回線だけが利用できなくなったので、このミニスマホにしました。電話回線が通じないのはdocomoの回線変更によるせいでVoLTE に対応していない端末は電話が使えなくなるためのようです。このミニスマホも対応しているか心配でしたが、電話回線は通じましたので結果オーライでした。思ってた以上にコンパクトでしたが、私の用途では満足のいくモノです。安いのでもう一台予備で買っておいてもいいかなと思っています。”
