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.

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

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.

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

Tips for buying a prepaid eSIM
โ Research your options: Before you travel, explore the eSIM plans available in Japan, looking for plans that offer the connectivity and data speeds you need, as well as coverage in the areas you'll be visiting.
โ Consider your needs: Reflect on how you'll be using your eSIM while in Japan. If you'll be making a lot of calls, look for a plan with a phone number and a high allowance of minutes. If you'll be using data-intensive apps like streaming video or online gaming, look for a plan with a high data allowance.
โ Activate your eSIM before you leave: It's advisable to activate your eSIM before you leave home, so it's ready to go as soon as you arrive in Japan. This will ensure that you have connectivity as soon as you land, allowing you to make calls, send messages, and access the internet right away.
โ Consider purchasing a local SIM card: In some cases, it may be more cost-effective to purchase a local SIM card when you arrive in Japan. This can be a good option if you're only staying in Japan for a short period of time, or if you need a lot of data and can't find a suitable eSIM plan.
โ Keep track of your usage: It's important to keep track of your usage when you're on an eSIM plan, as you may be charged extra for going over your allowance. Keep an eye on your data usage, and consider turning off data roaming or using a Wi-Fi hotspot to avoid overage charges.
