Find the best data eSIM in Japan

Redteago

4/5

I tried Redteago eSim plan in Japan and I must say that the convenience of an eSIM is unparalleled. Rather than physically swapping SIM cards every time I change countries, I simply activated the eSIM on my device with a few easy steps. It saved me from the stress of locating and purchasing a physical SIM card (specially because I was arriving late at night). The coverage was consistent across various neighborhoods of Tokyo and even in more remote areas during my 1-day trips to nature. I never experienced any significant drop in signal strength or call quality during my time there.

Airalo

4/5

I used Airalo and Nomad in Hokkaido when I was visiting Japan. Here is my review for Airalo. I had a great experience overall: setup of the eSIM was very smooth, but I was a bit disappointed with bandwidth speeds eventhough it was acceptable. I purchased Airalo's Moshi Moshi 1GB plan which is only compatible in Japan and is a data-only plan. The good : - Airalo's user experience is very good. The eSIM setup was very simple and was mostly about clicking on buttons through the entire process. - I was able to roam on the NTT Docomo network in 4G, which is really efficient in Japan. I did a few tests and was about to get roughly 80.6MBS download and 8.6MBS upload speeds. So great download speeds. Upload speeds could have been better. Airalo also advertised the eSIM as compatible with KDDI (another network provider) but I did not try it. The bad : - Too bad I did not get 5G it was a bit frustrating because my phone is 5G compatible. - Since Airalo is not a local network, my internet traffic was routed through Singapore, which is a bit far from Japan - so latency was not the best

Nomad

4/5

I tried both Airalo and Nomad when I was visiting Japan , here is my review for Nomad. The experience was overall very good. Too bad the plan did not offer 5G. What I liked : - Although I had to copy and paste my eSIM information manually the setup instructions were very simple and well explained. - The plan worked well and offered good speeds. I was able to get 69.2MBS download speed and 18.3MBS upload speed while I did my test in Sapporo downtown. What I did not like : - It's a bit unfortunate I was not able to get 5G while 5G was available in Sapporo - Since Nomad is not a local network, my internet was roaming through Honk Kong (I guess where Nomad server is). It was not a big issue but added an extra bit of latency.

Yesim

3/5

For my first time in Japan I used a Yesim eSIM in Japan and overall the experience was good. However I was disappointed my IP address was in the US meaning that my traffic was routed to the US. So latency & speeds were not so good :( I guess next time I'll use Airalo, heard a lot of nice things about them
