📌 24/7 Customer Support

: USIMSA offers around-the-clock customer support via KakaoTalk. This means any questions or issues can be resolved quickly, no matter the time zone.

📌 Free Data for Google Maps & ChatGPT

: A huge bonus! You can use essential apps like Google Maps for navigation and ChatGPT for quick queries without it eating into your data allowance. (This applies when using USIMSA's roaming network.)

With all these fantastic advantages, it was a no-brainer to choose the USIMSA eSIM for my Osaka adventure.

What About Local Speed in Osaka?

I used the eSIM extensively throughout Osaka and Kyoto, and the performance was consistently excellent.

📌 Uploading Instagram Stories

📌 Sending photos via KakaoTalk

Everything worked smoothly and quickly, without any frustrating lag.

Choosing the Right Data Plan for Osaka

Since I tend to use a fair amount of data for Instagram and YouTube, I opted for a 2GB per day plan. This was more than enough for my needs, and I never felt like I was running out of data.

However, if you're a particularly heavy data user or plan on streaming a lot of videos, I'd highly recommend going for an unlimited data plan for complete peace of mind.
