How to use Hypersims

4 years ago

Not sure if anyone knows what hypersims are, but here`s a nice tutorial for anyone needing to use them.

Hypersims are exclusively used to "hack" Japanese phones so that they can be used outside of Japan.

In Japan, they have their own mobile network called FOMA which is completely different than our GSM and GDSM networks. The hypersim forces the phone to go on the GSM and GDSM networks rather than FOMA.

The Hypersim is basically a microchip that you attach on top of your sim card.

In order for this to work, you have to put both your hypersim and sim cards together and find out where the microchip on the hypersim sits on your sim card. Then you have to cut a small box so that the microchip fits through the sim card.

Put them together and place them into the slot on your phone according to the instructions on which way the card should sit.
The hypersim should sit on top of the sim card with the microchip facing through the sim card.

Turn on your phone like usual and you will have a working Japanese phone in North America!

The most annoying part is that hypersim has a weaker signal so if you go into an area with no service you have to "revive" the hypersim by turning the phone on and off and then putting the sim into a regular 3G phone and activating the service there.

Not sure if anyone else but me needs this but for anyone looking into Japanese phones, this is highly useful.
