I will be flying to Tokyo next week for a brief vacation. Based on my previous trip to Japan and what I gathered afterwards, it appears that using data-only SIM cards in Japan will activate and prevent you from disabling the phone camera shutter sound as mandated by law. However, I've read online that some people didn't experience this.
1. Are there any known data-only SIM cards which don't have this problem?
2. Will using a portable WiFi router (where the Japan data-only SIM card will be in, instead of my phone) avoid this problem?
I am aware that other solutions include rooting and downloading silent camera apps, but the former isn't available for me (I just bought a Samsung Note 8) and the latter will have a lot of camera features and options missing (very eager to test my dual cameras on my Note 8 during the trip).
