Question 4

Will the Japanese eSIM work on the Shinkansen?

Accepted Answer

SimCorner’s eSIM for Japan automatically switches between the country’s top networks, KDDI (au), SoftBank, docomo, and Rakuten, to keep you connected along high-speed train routes. With the data from your Japanese eSIM, you can easily stream videos, track transit updates, or make data calls while travelling between Tokyo, Kyoto, and Osaka. Brief signal dips may occur only when passing through deep mountain tunnels.

Question 6

Is 10GB enough for 15 days in Japan?

Accepted Answer

Yes, 10GB is enough for 15 days in Japan. For a light-to-moderate user who primarily relies on navigation apps, messaging, and occasional web browsing, 10GB is generally sufficient for 15 days. However, if you plan on heavy video streaming, uploading high-definition content, or frequent tethering, we recommend opting for a larger Ultra 20–100GB plan or a Japan unlimited data eSIM to ensure complete peace of mind.

Does eSIM Japan work in rural areas like Hokkaido or Mount Fuji?

Major Japanese telcos maintain broad national coverage across both urban and regional areas.

Question 10

Does the eSIM Japan come with a local phone number?

Accepted Answer

This is a data-only travel eSIM and does not include a local Japanese (+81) phone number for traditional voice calls or SMS. However, you can maintain full voice and text connectivity by using data-based apps like WhatsApp, FaceTime, Viber, and Messenger. This allows you to stay connected with high-speed data without the privacy risks, mandatory passport uploads, or long retail queues associated with local SIM registrations.

Question 11

When is the best time to install my eSIM {{Country}} data plan?

Accepted Answer

Your device must communicate directly with the network servers to download the digital eSIM profile.

Question 15

When does the validity countdown start, and how are days calculated?

Accepted Answer

The validity period does not begin upon purchase or installation. The countdown starts only when your eSIM {{Country}} gets activated by connecting to a supported local network. From the activation time, your plan days are calculated based on continuous 24-hour cycles.

Question 16

Does the {{Country}} eSIM expire if left unactivated?

Accepted Answer

No, our {{Country}} eSIM does not expire or get auto-activated, unlike many other eSIM providers who enforce 15–30-day activation periods.

Question 17

Can I transfer my active eSIM {{Country}} profile to another phone?

Accepted Answer

No, travel eSIMs are single-use digital profiles that lock to the physical hardware of the initial device. Once a QR code has been scanned, it cannot be transferred to a different handset. Additionally, if you delete the profile from your settings, it cannot be re-scanned or reused.

Question 18

How do I track my data balance and purchase top-ups?

Accepted Answer

You can use the SimCorner App for live data tracking and instant on-the-go recharges.

Question 21

Can I use {{Country}} eSIM if my phone is currently locked to a network carrier?

Question 22

Why are iPhones from Mainland China, Hong Kong, or Macau incompatible?

Accepted Answer

Explore our physical {{Country}} SIM card options.

Question 23

How many eSIM profiles can I store and run on my phone at the same time?

Accepted Answer

Storage: Most modern smartphones allow you to download and store between 5 and 10 distinct eSIM profiles directly on their internal chip.Usage: While you can store many, you can generally only run one or two profiles actively alongside your primary home SIM card at any given time, depending on your device generation.

Question 24

Will this eSIM work on a jailbroken (iOS) or rooted (Android) device?

Accepted Answer

Yes, but we cannot guarantee optimal network performance because jailbreaking or rooting modifies core security protocols. Security flags within cellular operating systems can occasionally interfere with the profile registration process or prevent automatic network connections.

Question 25

Can I keep my home SIM in my phone alongside the eSIM {{Country}}?

Accepted Answer

Yes, modern smartphones feature Dual SIM technology, allowing your physical home SIM and your digital eSIM {{Country}} to run simultaneously. You simply assign data usage to your SimCorner profile while keeping your home line active for incoming OTPs.Note: Receiving incoming calls will trigger roaming charges from your home provider.

Question 26

Can I keep my original WhatsApp and iMessage accounts?

Accepted Answer

Yes, these services are linked to your home phone number or account rather than the SIM card. When you insert your eSIM {{Country}}, your apps may prompt you to update your number—always select Keep Existing Number. This ensures your account, chat history, and contacts remain tied to your home number, allowing you to message and call as usual throughout your trip.

Question 27

Does my {{Country}} unlimited data eSIM have a hidden Fair Usage Policy (FUP) throttle?

Accepted Answer

No, we believe in complete transparency. Unlike other providers who hide their speed drops in fine print, our limits are fully disclosed up front.

Question 28

Can I still receive bank SMS codes (2FA) while using eSIM {{Country}}?

Accepted Answer

To receive bank verification SMS codes (2FA) using our eSIM for {{Country}}, your device must support Dual SIM functionality so your home SIM remains active alongside your travel plan.Pro-Tip: If your phone only runs one active SIM at a time, your home line will become temporarily inactive. To prevent losing account access, we highly recommend setting up email-based 2FA or an authenticator app before you depart.
