SnapPea PhotosはWi-Fiでなくてもオケ

つまり「SnapPea Photos」は、インターネットにさえつながっていればいい、ってことだね。

Rejoice, your connection has been upgraded! SnapPea can now connect when your phone is on a different Wi-Fi network and on mobile data (3G, 4G).Because this is a major update, it’s necessary to update to the latest version of the SnapPea mobile app to connect.
