Camera bag, hockey bag, golf bag, gym bag kept in car. Always keep phone clean of texts, history. Always off until you need to use.
Only use when decision to meet a chosen SP and backup has been made including day and time. Book day before. Phone off until time to confirm, keep on until session over. Clear all texts , calls and history. Back in bag. All contact made while away from house or only one there.
Browsing and research and planning done on other personal devices at my leisure. Use incognito mode, check history use. Although, some "spur of the moment" opportunities would easily be accommodated.
Found this to work without any problems. Cover story for phone would be simple. Old phone replaced and never threw out. In bag, forgot it was there.
Not needing any of this any longer.
