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 an Operator Notification

    Worked flawlessly all though Japan. Used it for a day in South Korea and one day in Singapore too. Connected immediately in all countries. Got speeds of 25MBPS+ in Japan and korea and 50mbps in Singapore.

  2. Ninad Gupte (verified owner)

    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.

    • Services Tsim

      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.

  3. Rishabh Kandari (verified owner)

    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

    • Services Tsim

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

  4. Amita (verified owner)

    Only Japan Sim was excellent. There was no network issue anywhere in Japan. The speed was very fast.

  5. MrRajranawat (verified owner)

    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 🙂

    Best Japan SIM in Indian market. Spent 18 days in Japan visiting four cities – Tokyo, Kyoto, Osaka & Hiroshima. Excellent connectivity, great reception in calls to India as well as within Japan. Fast data network. Google maps functioned in realtime with no breaks.

    • Services Tsim

      Thank you for your kind review and for specifying where it worked.

  7. Ram (verified owner)

    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.

    • Services Tsim

      Thank you for your kind review.

  8. SS (verified owner)

    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.

    • Services Tsim

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

    Worked exactly as described. I had some trouble because I did something wrong, and it was a Sunday morning, but TSIM support helped pretty promptly once I reached out. Would use this service again, for sure.

    Worked well in Japan, calling and data

  11. 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.

    • Services Tsim

      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.

  12. 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.

  15. Suvankar Barai (verified owner)

    Calling was working but take delays in hearing.
    Internet data was not working.

    No doubt it was helpful for me to talk to my father and mother as I was alone in Japan.
    But getting problem as there was no internet to use google map.

    Request to solve this problem in future.

    • Services Tsim

    The validity of the SIM would start from the time that it first registers on the Japan network.

  6. Answered by the admin For that you need to take the 28 day renewable SIM card, and then renew it once. If you would like to top up the renewal before you leave, speak to the helpdesk via chat
