Foreign manufacturers officially launched a new micro SD card, integrating with SIM card contacts.

Two-card slot should be a general method of scalable storage today, while traditional three-card slot is becoming rare, or even disappearing gradually. Previously, many netizens did their own micro SD cards themselves by putting metal sheets of SIM cards behind them. Now, some foreign manufacturers have officially launched such a micro SD card, which integrates with the contacts of SIM card.
IDEMIA showed FuZion at MWC2019, which creatively combines micro SD card with SIM card. That is, FuZion is based on the form of micro SD card, while integrating with SIM contacts.

In fact, FuZion was demonstrated in 2017, but it was launched on a small scale at the end of last year.
Of course, FuZion will be shipped in network operators rather than retail channels. At MWC2019, officials also demonstrated inserting a 128GB FuZion supporting Vodafone network for Samsung Note 9.
