質問お願いします。
もう使っていない古いiPhoneのSIMカードですが、捨ててしまっても問題ないのでしょうか。
それともそこに何かデータが残っているのでしょうか。
携帯はすでに初期化済みです。
よろしくお願いします。

携帯自体を初期化したなら SIM (Subscriber Identity Module) も電話番号とか携帯会社との通信方式などの個人に特化された情報が入っているのでそれも初期化されているはずです。また IC チップのメモリーはコンピュータのハードドライブと違い、メモリーの情報はそれを消せば完全に消えています。
PC のハードドライブの場合初期化のためリフォーマットしても先頭部分にあるドライブ自身のデータを消すだけなので肝心なメモリー情報は全然消されておらず、それなりの検査アプリを使えば消されたはずのデータが全て再現できてしまうのです。
それでも心配ならその SIM カードを捨てる前にプライヤーなどで縦方向に挟んで壊し粉々にしていまいましょう。

＞大体メモリーじゃねーし
SIM カードは Micro SD カードの完全なメモリーチップです。基本的にそのキャリアの通信方式を記憶しています。しかし「持ち主の電話番号を記憶している」というくだりには自信がなくなりました。

どちらにしても人が使っていた SIM カードは誰でも使えるので機械的に破壊した方が安全でしょうね。まぁ、そのままゴミ箱に捨ててもその行為を見られていなければ確率的にビーチの砂浜で落とした Dime Coin を見つけることに等しいですけど。
