Google VoiceとmagicJackの比較

クレジットの有効期限

Google Voice：非公開。magicJack：有効期限あり。クレジットの有効期限は、料金表には現れないコストです。一度にチャージする金額が大きいほど、また通話の頻度が低いほど影響が大きくなります。緊急時に備えて購入したまま使われていない残高こそ、利用停止ルールの対象になります。

プラットフォーム

Google VoiceはiOS, Android, Webで利用できます。magicJackはiOS, Android, Windows, macOSで利用できます。この点で決まる比較は、実際より多くあります。どれほど優れたサービスでも、手元の端末で利用できなければ候補にはなりません。また、代わりに1時間スマートフォンを耳に当て続けることになるなら、デスクトップ用クライアントの有無は見た目以上に重要です。
