duoSIM

Allowing two SIM cards in one device

Utilizing Taisys’unique patented SIMoME™ technology, the ultra thin SIM allows for the placement of two smart cards, into the single SIM card slot of traditional single SIM slot devices

The duoSIM knows and supports all relevant GSMA/3GPP/ETSI standards, making it compatible with all standard devices from older feature phones to the latest smart phones.

Using the duoSIM, any device becomes capable of holding two SIM cards, and having two SIM cards in the one slot of the device means the user does not have to physically remove and exchange the SIM card when the user travels, eliminating the possibility of losing and misplacing the cards.

The user can easily select which card to use directly from the SIM Tool Kit (STK) menu, or calling a specific short code to do the selection.

The duoSIM can also support having multiple numbers with automatic or manual selection of which number to use.
Support for international calling services can be included through the Smart Dialer function, allowing customizable and modifiable setting for the issuer and simplified usage for the user.

The duoSIM also supports standard GSM Remote File Management (RFM) through OTA.

The duoSIM is supported by all devices, allowing any and all devices to hold two SIM cards
