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 through Reverse Call
This SIM uses reverse call for outbound calls. When you dial, the call disconnects and you receive a return call connecting you with the number you want to speak to.
If you fail to get a call back, redial the number followed by the “#” key.
Making calls to India:
Remember to add the country code when making calls to India. Check that the number begins with +91 before dialling. 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.
Emergency calls
Please note Japan emergency number 119 & 110 etc will NOT work on this card.

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.

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

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.

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.
