Activation, Validity and Phone Number

This SIM card is automatically activated on first use in any covered country. Validity is counted from the exact time of first use, and ends at the same time at the end of the validity period.

Japanese phone number will be provided by SMS when you reach Japan. After your order, an email will be sent to you describing the process. Should you require your Japan phone number before departure you need to pre-activate your SIM card. Simply reply to that email telling us the date you would like to pre-activate before travel. Your validity in that case will begin on activation, so please activate only a day or two before departure.

Receiving calls

People anywhere in the world can dial your Japan number directly to reach you, for example, +81 13 12345678.

Making calls to India:

Remember to add the country code when making calls to India. Check that the number begins with +91 before dialing. E.g. to call India number 022 24216344, dial +91 22 24216344

Making local calls

To make local calls use the full international format. E.g. to call a Japan number from any country use (for example) +81 90 12345678.

    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.

    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.

    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.

    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.

      We apologise for the trouble you had using this card. We have forwarded these comments to the product team for further investigation.

    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.

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

  4. 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
