SIM card is the abbreviation of subscriber identity module, also known as smart card and subscriber identity card. GSM digital mobile phone can only use this card.

There are three kinds of SIM cards: ordinary SIM card, Mini SIM card and Nano SIM card.

Standard card (ordinary SIM card)

Most mobile phones use the SIM version, and I know it, so I won't say much.

Miniature SIM card

Micro SIM card, also known as 3FF SIM card, is the third type of SIM card, and its size is 12x 15mm, which is 52% smaller than the second type of SIM card used in our mobile phones.

In fact, the small card is the kind with a chip on the standard card. What really works on the "standard \ small dual-purpose card" is the "small card" above, which can be removed from the dual-purpose card. At present, the popular style in China is "standard card", and small cards can also be changed into "standard cards" (as long as there is a Cato). Now apple's products (iPhone4S, iPhone 4. (iPad, ipad version 2. 3G) all use Micro SIM card.

Nano SIM card

Nano SIM card is a 4FF standard SIM card, which was first proposed by Apple and used for nano SIM card and micro-SIM card.

Submitted by European Telecommunications Standards Institute (ETSI). This Nano SIM card is one-third smaller than the Micro SIM card, 60% smaller than the ordinary SIM card, and its thickness is also reduced by 15%. It is said that operators are interested in Nano SIm card, and it is expected that the first mobile phone using Nano SIM card will be launched in 20 12. [ 1]

On the recent CTIA wireless 20 12, Giesecke & Devrient) showed the 4FF standard SIM card-Nano SIM card. Judging from the SIM card styles in the exhibition, the Nano-SIM card is smaller than the Micro=SIM card that has just been gradually realized, and the rounded corners around the original metal contacts have also become right angles. [2]

In March this year, Apple, Nokia and RIM disagreed on the standardization of SIM cards. Apple supports the nano SIM card standard, while Nokia, RIM and Motorola support the micro-SIM card. Innovative Apple hopes that the SIM card can be smaller to make room for other mobile phone components.

Comparison of three kinds of cards

20 1 June1According to American media reports, Apple's Nano-SIM card design proposal was adopted by the European Telecommunications Standards Institute (ETSI), while the proposal jointly submitted by Nokia, RIM and Motorola was rejected, despite the opposition and criticism of different proposals on the 4FF(Nano-SIM) standard. On September 3rd, 20 12, Beijing time, Apple officially released the iphone5 mobile phone, and the new generation of iphone5 mobile phone officially adopted the Nano-SIM card.

Note: As the trend of smart phones is thin and light, the space in mobile phones is particularly important. Ordinary SIM cards take up too much space, so the current trend is that Micro SIM cards, also known as small cards, can save more space for the internal structure of mobile phones. At present, most mainstream high-end models use Micro SIM cards.
