Questions before you travel

Japan eSIM FAQ

What does an eSIMNavigator Japan plan include?

Launch plans include a fixed amount of mobile data for a stated validity period in Japan. They do not include ordinary calls, SMS, or a phone number.

Will my US phone work?

It must support eSIM and be carrier-unlocked. Model name alone is not enough because some regional or carrier variants differ.

When should I install it?

Install on reliable Wi-Fi only after reading the plan's activation policy. Some plans start at installation; others start when they first connect to a supported network.

Can I keep my US number?

Usually, on a compatible dual-SIM phone. Select the eSIMNavigator line for data and keep the US line for calls or texts. Your home carrier may still charge for roaming activity.

Can I use WhatsApp, maps, or iMessage?

These apps use mobile data and normally work when the plan has a connection. Keep the existing account number selected and avoid changing numbers unless you intend to.

Does the plan guarantee 5G?

No. 5G depends on the exact plan, local partner network, location, congestion, device, and network settings. Only verified 5G details appear on a plan card.

Can I use hotspot?

Only when the exact plan states that hotspot is allowed. A missing or pending label means eSIMNavigator has not verified it yet.

What if the eSIM does not work?

Keep it installed, use Wi-Fi, check the selected data line, roaming and APN instructions, then contact eSIMNavigator Support. Do not delete a one-time profile unless support confirms it can be replaced.
