What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. If an activation date is required the QR code / Notification is sent after activation, else 24hours after completing your documentation.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.
- Transfer of eSIM: To transfer an eSIM from one phone to another you must visit the store of the Operator concerned. However some USA eSIMs can be transferred from one iPhone to another.
Activating eSIM on your Device using a QR Code
Most eSIMs are installed using a QR code. The QR code is sent to you by eMail. You need an Internet connection to install an eSIM
iPhone XR, XS and newer
- Go to Settings, then Cellular.
- Select Add a plan, and the Camera app will open.
- Point your camera at the QR activation code until you see a message that says Installing cellular plan.
2021 Android and newer
- Go to Settings > Connections > SIM card manager
- Tap Add mobile plan
- Tap Add using QR code
- Scan the QR activation code
Activating eSIM on your Device using an Operator Notification
T-mobile, AT&T and some other operators make it even simpler to install eSIMs. They send a notification directly to your phone. Just tap on the notification and follow the instructions as in images below. The notification is sent to the phone you intend to use on your trip for which you have given us the EID and IMEI number by dialing *#06#.

I purchased TSIM card before traveling to Japan, it was delivered in just 2 days to my home address. The process of application online is simple, they will need a copy of passport. The verification is online too with a pic and passport. The chat support is online and is prompt. They help you in confirming whether documentation is done before proceeding to Japan and whether sim will be active. SIM is activated automatically in max 3-5 minutes when inserted into the slot after landing in Japan. Make sure to keep the roaming mode on. The network coverage is good. I purchased a 3 GB sim for my trip of 3 weeks, I used it for navigation and other things whenever I was out of wi fi and 3 GB data was more than sufficient for me. I recommend this SIM if you do not need phone nunber for stay in Japan It is more than it’s worth. Moreover it was sent in a stainless steel credit card case (complimentary) with a utility/light travel adaptor for Japan which was complimentary again. Thanks TSIM for making my Japan trip wonderful.

I had the worst experience as TSIM not only goofed up by providing me a SIM which was not recharged, but their support was also extremely slow and below standards. While I was stranded overseas without a data connection, TSIM would send 1 reply in a day asking basic questions and giving rookie answers. All this, even though I had sent screenshots showing that my SIM show 0 balance. I lost 5 days of my travel getting this point across after which TSIM recharged my SIM and it started working. By then, I had already purchased another SIM in Japan so it was a waste of my time, money, and loads of inconvenience. I had bought the SIM for a smooth experience, but henceforth I will not depend on any such. Buying SIM at destination, or taking a roaming pack from India are much better options.

This is a prepaid SIM card and does not need any recharge from our side. The bundle shows as data balance, not credit (talkative) balance since it is a data only card. We regret the misunderstanding and the inconvenience and thank you for taking the time to record your experiences.

The sim worked perfectly during my 5 day stay in Japan. The network coverage was perfect in Nagano, Kanazawa and Osaka. I was using the sim for updating vdios on my social media( outside the hotel) and even then I did not run out of data.
Considering the value of the sim, it was perfect

Thank you for your kind review and for detailing the cities in which it worked.

I ordered SIM on November 13, 2019 and received next day. very fast service by TSIM. I went to Japan and took Unlimited Japan SIM Card from TSiM and its was very good network coverage. 4G speed was good even in underground railway stations. I recommend this sim to people who planning to travel to Japan (Tokyo).. Nice and Speedy network coverage. Just reach Tokyo and insert the Sim & it will work 🙂

Purchased a data only sim for Japan with a week validity.
Had to configure the setting manually and after that all was smooth.
Connectivity speed was good and network was available in all places.

The sim functioned really well. There was good network.
There was an initial staring issue but it was soon resolved.
One suggestion: Kindly have a notification system that tells you that your package is about to expire so that we are aware that we will be cut off with the network and so we can contact you for help or a renewal process in case our stay is prolonged.
Thank you for your efficient services.

Thank you for your kind words and suggestion. We have forwarded your suggestion to our product team.

Worked well in Japan, calling and data
hanatrvl (verified owner) –
Make sure you ask for Japan specific sim number, else you will get +44 based sim which is not useful if you are in Japan to receive local calls.
Else works ok, data and calling.

This SIM card automatically issues a Japan number on arrival. Only if you need to know the number in advance do you have to request the helpdesk to issue one. Thank you for your review.
Don (verified owner) –
The SIM card did work, but data was always an issue. Most of the time I had to use free Wi-Fi around to find routes etc in google maps as TSIM internet wasnt working or was tooo slow. Had to restart and troubleshoot sometimes to make it work especially when 100 MB limit got over.
Calling to India was very good. But I couldn’t use it for calling most of the local Japan numbers (mainly the ones which had IVR) Struggled a but due to this. Also Japan number wasn’t recognized for using in Uber, and had to put the UK number of the same sim card to proceed.
Anyway giving rating 3 as your support team was awesome, there were quick in responding in chat for any questions raised.
Services Tsim –
We apologise for the trouble you had using this card. We have forwarded these comments to the product team for further investigation.
