nano - sim
some phone models utilize a "hybrid" sim tray, which allows two sim cards or one sim card and one microsd memory card. huawei's mate 20 range introduced a proprietary memory card format known as "nano memory", which exactly matches the dimensions of a nano sim card.





















































some devices accept dual sims of different form factors. the xiaomi redmi note 4 has a hybrid dual sim tray which accepts one micro sim card and one nano sim card, the latter of which can be swapped for a microsd card.

the "mini-sim" (or 2ff) card has the same contact arrangement as the full-size sim card and is normally supplied within a full-size card carrier, attached by a number of linking pieces. this arrangement (defined in iso/iec 7810 as id-1/000) lets such a card be used in a device that requires a full-size card or in a device that requires a mini-sim card, after breaking the linking pieces. as the full-size sim is no longer used, some suppliers refer to the mini-sim as a "standard sim" or "regular sim".
