User reviews

ビジネスでないと使えないのか

全く使えない。ビジネスユーザーようなのか、myドコモにログインしたりするだけで、登録もできない。意味不明なアプリです。電話なんてなにもできない

ストレス

自宅のwifi環境が良くないのか?よく通話不可。認証に失敗したとなり掛けられません。修正至急希望します。

使用不能

パソコンで検索しましたが、そもそも設定方法が不明です。

iPhone14で音声がおかしくなって使えない

iPhone14にインストールして使おうと思ったのですが、
声がロボ声みたいになりノイズで全く聞き取れない。
全く使い物にならない。

番号が選べれば最高のサービスに。

こちらのサービス、実は050plusがベース。
なので0570への通話が安い。0120にかけられる。(例外あり)
1番安いデータSIMで契約すれば約1500円でモバイル回線より利便性が高い、通話し放題の番号が持てます。
唯一の欠点は、番号が選択できないこと。
050plusではできるのだから、なんとかして欲しい。
番号が気に入らず、今は050plusを再契約してます。
今後に期待しています。
