I'm currently traveling in Japan and my eSIM data is running low. What are the steps I should follow to top up my plan? Is it straightforward to do this while I’m here?

Topping up your eSIM in Japan is quick and easy! Simply open the eSIM TopUp app, navigate to your active plan, and select the 'Top-Up' option. You'll be able to see available data packages and purchase one with just a few taps.

I just topped up my eSIM in Tokyo, and it only took a few minutes! Just make sure you're connected to Wi-Fi when you do it, as there were issues with my mobile data at the time.

I was worried about topping up while in Japan, but it was super simple! Just remember to check your payment methods in the app beforehand to avoid any hiccups.

Make sure you're aware of the available top-up options before your data runs out. I ran out and had to find Wi-Fi to top-up—definitely not fun! Plan ahead.

I found the app to be user-friendly. After purchasing my top-up, the new data activated instantly, and I kept track of my usage through the app. No problems at all!

If you're in a busy area, try topping up during off-peak hours to avoid any slowdowns. I did this and it worked perfectly for me.
