Bigger is always not the better. There are people who like things "Smaller". I am talking about worlds smallest mobiles. So I am going to list here some of the worlds smallest mobiles out there.
Modu Mobile

This phone is new on the market but it’s already been named “The World’s
Lightest Phone” by The Guinness Book of World Records. It weighs just
over forty grams and has dimensions that are just 72 x 37 x 7.8 mm. In
other words, the Modu Mobile is miniature. However, the phone is capable
of doing a wide range of different things including SMS messaging, MP3
playing and taking photographs. Some of this is done through attachments
that may add bulk to its initial small size.
Nevertheless, even with
attachments, this phone is setting the benchmark for small cell phones
across the globe. It isn’t on sale yet but will be in certain markets by
the end of the year so those of you who want to be on the cutting edge
should start thinking now about getting your fingers on this phone.
