number on the card, enter your individual PIN number and then
dial the number of the person you wish to speak to. These cards

Memory Cards
Memory cards were introduced
around 1990 when technology in mobile phones and digital cameras
began to evolve and become more complex. Today it’s not unusual
to have a mobile phone with a built in camera of 5 mega pixels
which allows you to take photos of huge resolution. As in-built
storage on phones is very low, on average around 10MB, the need
for extra storage came about and so the memory card, the SDcard
was one of the first.
While the SDcard was the first to be introduced this was quickly
followed by the MiniSD, MicroSD, the MS Micro2 and the Micro
SDHC. One of the first manufacturers to jump on the bandwagon
with the need for memory was SanDisk, although many others have
followed. Not only were they used in phones, cameras and
camcorders they were also taken advantage of by those using
video games controllers on the likes of the Xbox, GameCube and
Play station.
Memory cards range from 512MB to a massive 8GB which is usually
put to good use in the high end digital camera range. SanDisk
produce an 8GB memory stick M2 which many of the new slim Sony
Ericsson phones use. With multi-media phones having high
resolution cameras, then large amounts of memory for storage is
essential. The beauty of the M2 is that it is compatible with
devices that use the memory stick PRO Duo with the use of an M2
adapter. The memory stick M2 also comes in storage of 1GB, 2GB
and 4GB.
The Pro duo memory is used in the likes of consoles such as the
Play station 3, Sony PSP, digital camera such as Sony’s
Cybershot and some of the many Sony Ericsson phones.
The microSD cards are used in some of the smaller mobile phones
and many come with a special USB adapter, this makes
transferring media to and from your device quick and easy.
Simply take the microSD card from the phone put it in the USB
adapter and stick this into your computer and transfer your
music e.t.c directly onto the card and then back into the phone
or device. MicroSD cards come in sizes of 1GB or 2GB from
SanDisk.
The MicroSDHC memory cards are used in the majority of
Blackberry phones and the smart phones such as from HTC, LG and
Nokia. These are usually either 4GB or 8GB and are used to store
a variety of multimedia such as music, video and high quality
photographs. A card reader can also be used with the memory card
for ease of use when it comes to transferring media to and from
the card.
