### 2/5 — 通じない

*2026-01-15*

会社の執務室内での通話時、こっちには相手の声が聞こえるが相手にこちらの声が全く伝わらず、発信や着信があるたびにローカーに出ないといけない。ローカーもまた場所による。これでは全くダメ。

### 5/5 — ありがたい

*2025-12-25*

ＮH K受信しないのに視聴料盗られてる圏外住みなので、この電話もジージー雑音が少しします。
でも楽天株主優待のお陰で無料通話📞させて頂いて感謝です

### 1/5 — 繋がりません

*2025-12-19, version 2.19.0*

残念ながら出先で電話してまともに会話できたのは数回程度です。

### 1/5 — 全然繋がらない

*2025-12-17, version 2.19.0*

まず繋がらない。
楽天回線やっぱりダメなんだな。と思います

### 1/5 — 相手に自分の声が聞こえない

*2025-09-18*

楽天の株主優待で使い始めました。

電話をすると、
こちらに相手の声はきこえるが
相手に自分の声が聞こえません。

アンインストール
再インストール
マイクのセキュリティの確認
iPhoneの再起動　等

公式サイトで案内されてる全てを試してもできません。
このために株を買ったのに残念で仕方がないですね。
これ、株主優待だからまだあれですが　実際に楽天の通信を使ってる人からしたら使えないサービスってことですよね？

早く改善してもらいたいです。

### 3/5 — ログインしているのに

*2025-09-10*

ログインしているのに、キャンペーンなどのくじをクリックすると再度ログイン画面が表示されるので、フェイスIDでログインできるように改善されたら良いなとアプリ内でコメントしたところ、IDが確認できませんと表示されるようになりました。

その後、電話やLink内の機能は利用できるけれど、メールが使用できない旨の表示も現れました。

アプリを削除して再度ログインしたり試していますが、多くの機能を利用している訳ではないので、メールと電話、くじなどを楽しみながら利用させて頂けましたら幸いです。

### 1/5 — 使い物にならない

*2025-08-04, version 2.19.0*

ゴミ同等。通話切れる。電波悪い。着信あっても取れない。
不具合だらけです

### 3/5 — 不完全

*2025-08-01, version 2.19.0*

突然に切れる、すぐに繋がらない

### 1/5 — 音質が悪い

*2025-07-29, version 2.19.0*

通話先で音質が悪いと言われ、結局はキャリア回線で、電話することとなり役にたっていない。

### 1/5 — 強制終了未解消

*2025-07-24*

2025.07.24.17:55現在
相手に連絡した場合、①コールする場合②ノーコール強制断③繋がるが音声が送受信共に無音といった不具合。
不具合というか、これはインフラとしての「電話」としての機能は果たしていない。
「楽天リスクオフィス」だけの問題の様であるが、繋がらない回線を提供するな。
だから楽天はキャリアとは認められないのだ。
お陰で相手と喧嘩になり掛けたではないか。
