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:
| Provider | Top-Up? | How |
|---|---|---|
| Airalo | โ Yes | Open app โ My eSIMs โ Top Up |
| Ubigi | โ Yes | Open app โ My Plan โ Add Data |
| Saily | โ No | Buy a new plan instead |
| Holafly | โ No | Contact 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)
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.
