「長期間利用しない場合、携帯番号を保管してもらえる」ですね?
When you don't use your mobile/cellular phone for a certain period of time, you can ask the service called "Storing Phone Number".
もう少し詳しくすると、
「(海外赴任・留学などで)長期間利用しない場合、電話番号を保管し、帰国後再利用できる。」
If you do not use your mobile phone for an extended period of time because of going overseas to work or study, you can ask the service for a "Storing Phone Number". When you are back, you can use the same number again.
こんな感じでいかがでしょうか?^^
