Frequently Asked Questions about Japan eSIM

When does my Japan plan validity start?

Validity begins when your eSIM connects to a supported local carrier network (NTT Docomo, SoftBank) in Japan for the first time. Purchasing or scanning at home will not start the countdown.

Can I make phone calls or receive bank SMS in Japan?

AeroSIM provides high-speed data. You can keep your primary physical SIM active to receive incoming 2FA verification SMS texts while using AeroSIM for data. VoIP apps (WhatsApp, Telegram, FaceTime, Signal) work flawlessly.

Can I use mobile hotspot / tethering with this plan?

Yes, mobile hotspot and tethering are 100% supported on all Japan plans at no extra charge.
