Don't Panic. You Have Options.

Your eSIM ran out of data or hit its expiry date. You're in Japan with no internet. Here's what to do, in order of speed.

---

Option 1: Top Up (2 Minutes)

If your provider supports in-app top-ups:

ProviderTop-Up?How
Airaloโœ… YesOpen app โ†’ My eSIMs โ†’ Top Up
Ubigiโœ… YesOpen app โ†’ My Plan โ†’ Add Data
SailyโŒ NoBuy a new plan instead
HolaflyโŒ NoContact support

You need WiFi to top up (since your data is gone). Connect to hotel WiFi, konbini WiFi, or cafe WiFi first.

Option 2: Buy a New eSIM (5 Minutes)

If top-up isn't available, buy a second eSIM:

1. Connect to any free WiFi (hotel, 7-Eleven, Starbucks)

2. Open Airalo or Saily app

3. Buy a new Japan plan (from $4)

4. Install the new eSIM

5. Turn off the old one, turn on the new one

Your phone can hold 8-10 eSIMs. Adding a new one doesn't delete the old one.

How to Prevent This Next Time

1. Check remaining data daily โ€” provider app shows balance

2. Set a data usage alert on your phone (Settings โ†’ Cellular โ†’ Data Usage)

3. Buy slightly more than you think you need โ€” the price difference between 3GB and 5GB is only $3-5

4. Use data saving tips โ€” 15 tips to cut usage 50%

Emergency Contacts Without Data

Even with no eSIM data:

  • Emergency calls: 110 (police), 119 (ambulance) โ€” always work
  • Hotel front desk: walk there, they speak some English
  • Konbini staff: can help with basic directions
