Unlike previous Eye-Fi Card WiFi works on the Mobi card actually now quite well. Unfortunately, the Eye-Fi card has this time rendered quite useless, that the mobile phone needs to pair a 10-digit number that is not printed on the card, but only on the packaging. Of course goes quickly lost, and then it is very cumbersome to pair the card. Another problem is that the card is not reliable as a standard SD card is unreadable.
