APN切替ナビ vs NetUsageLog

APN切替ナビは、iPhoneでMVNOや格安SIMを利用している方向けに、APN構成プロファイルの削除・インストール・確認手順を案内するアプリです。 物理SIMとeSIMを組み合わせたデュアルSIM環境では、利用する回線やMVNOの組み合わせによって、APN構成プロファイルの入れ替えが必要になる場合があります。 本アプリでは、利用中の2回線を登録し、使いたいデータ通信回線に応じた設定手順、公式APNページ、トラブル診断を表示します。 本アプリはAPN設定を自動変更したり、構成プロファイルを自動インストールするものではありません。実際の設定変更は、iPhoneの設定アプリ上でユーザー自身が行います。
