Activation and Validity

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

Receiving calls

People anywhere in the world can dial your Japan number directly to reach you, for example, +81774132 12345.

Making Calls through Reverse Call

This SIM uses reverse call for outbound calls. When you dial using reverse call, 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 local calls

To make local calls use the full international format. E.g. to call a Japan number use  (for example) +81 4555 1234.

Emergency Call Number.

Please note Japan emergency call numbers E.g. “119” will NOT work in this card.

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


TSIM’s customer service agents can be reached via email at services@tsim.in or phone +91 22 24216344.

Should you use automatic or manual network selection?

There are two ways of selecting a network. You can either set your handset to use AUTOMATIC Network selection or MANUAL selection. When using automatic selection the handset will look for all networks that it is able to attach to and logs onto the first network it finds. When using manual selection you must manually search through the networks and select a network to attach to. We recommend using automatic network selection. Please refer to your handset manual to check the default settings for your phone.

Setting up call forwarding/divert

To activate call forwarding/call divert, dial *102(phone number in international format)#. You will get a confirmation message on the screen. For eg. *102912224216344#. To deactivate dial *103#

Setting data on your phone

Please ensure Mobile Data & Data Roaming is enabled on your phone. Setup APN (Access Point Name) manually as follows:

Set Access Point Name (APN) in your smartphone to “globaldata” without any username or password

On Android Phones, tap the Menu button  /  Settings / Mobile networks  / Access Point Names / New APN / Set Name & APN as “globaldata” / OK / Save
On iPhone: Tap Settings / General / Network / Cellular Data Network / APN and enter “globaldata”. Leave username & password blank.  Tap Network
On iPhone6 & above:
a. While connected to WiFi, open Safari and goto: m.apnchanger.org
b. Select Manual
c. Enter “globaldata” in APN Name (small letters & no spaces) and click install.
d. If asked for a PIN enter your iPhone 4 digit unlocking PIN
e. Approve the installation of the unsigned profile.
On some iPhone devices you will need to remove the existing current Profile (found in Settings-> General -> Profile -> Existing Profile -> Remove) before installing the Globaldata APN.
On Windows Phone: Go to Apps list / Settings / Mobile Network / Add Internet APN / Set APN as “globaldata” / Save

    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.

    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

Questions and answers of the customers

  1. Answered by the admin

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

  2. 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
