こちらの記事を参考に、MVNOのデータ専用SIM利用時のアンテナピクト＆セルスタンバイ問題回避のためのスイッチを作ってみた。
スイッチの追加場所はモバイルネットワーク設定。

まずは必要なリソース追加

+    <string name="mvno_sim_custom_summary_enable"></string>

+    <string name="mvno_sim_custom">MVNO Data専用SIMパッチ</string>
+    <string name="mvno_sim_custom_summary_enable">MVNO等のDATA専用SIM利用時にアンテナピクト表示およびセルスタンバイ問題を解決する</string>
+    <string name="mvno_sim_custom_summary_disable">MVNO等のDATA専用SIM利用時のアンテナピクト表示およびセルスタンバイ問題パッチを無効にする</string>

packages/apps/Phone/res/xml/network_setting.xml
+    <CheckBoxPreference
+        android:key="mvnosim_custom"
+        android:title="@string/mvno_sim_custom"
+        android:summaryOn="@string/mvno_sim_custom_summary_enable"
+        android:summaryOff="@string/mvno_sim_custom_summary_disable"/>
