FAQ: Japan eSIM
Does this drain my battery?
No. Using an eSIM is much more battery-efficient than keeping a Pocket WiFi router connected via WiFi all day. It uses your phone's standard cellular radio.
Can I use TikTok and Instagram?
Yes! Unlike some public WiFi in Japan which blocks certain sites, Ovosim gives you open internet access. Great for uploading Stories on the go.
