which is better? post paid or pre paid

if your still considering what kind of billing plan you want to have these are some cons and pro of post paid and pre paid

this will give you or at least remind you of what you are getting

if you dont know which one to choose

this are the basics that will guide you in choosing your network and cap plan

whats available
value for money

first at your network

no extra fee for local roaming
good support (customer service)

your plan

depending on what you can affor and what you really want

I reccomend value for money

choosing a cellphone?

arent you sure of buying a cellphone that will fit you?

theres a lot of depends on your needs, lifestyle and of course whats available for your budget

of course i recommend the most efficient model.

first its within your budget range

what do you really need

extra to price ratio

cellphone capabilities

what do you really need

timer calendar alarm
to do list
txt messaging

voice recorder
3G capable
storage micro mini sd mmc
connection usb connection infrared bluetooth wireless 802.1 abg
proof weatherproof splashproof waterproof shockproof

this is actually a common sense
i just want to add some topics about cellphones.




additional casing

avoid dropping it
chain it to yourself

b4 i was thinking of buying a splash or waterproof shockproof and weatherproof cellphone

but because of the gave me a second it worthy?

why should we buy them?
lifestyle. if you have a rugged lifestyle like what i have (sports/outdoor

recreation..great challlenges.whatever) i would say that it fits the occasion..
unique. yeah because not all mobile phones have the same capabilities and resistance to weather..

durable. well if it got more resistance...then it is likely to have more life.

trend. not really because it is not that popular and not everyone use it.

compare a cellphone with the same capabalities 5140

unique casing design and material...

i think all mobile phones or cellphones are designed to be water proof and splash proof thats why most of the time you can still save your mobile phone if it get wet

maybe cellphones have fuses or circuit breakers to reduce the damage of short circuit.

Nowadays batteries are designed to be compact and waterproof to avoid short circuit.


eversince, these two dont have a good relationship

water can cause a short circuit to any

pure water is not a conductor but in our community there is no such thing as 100% pure water...maybe 99.99% pure but that 0.01% may cause it to become a

we know that water is a universal solvent because it can almost dissolved everything...if that 0.01% is an ionic compound(i.e. salt (NaCL)) and is dissolved in will break into (Na+ and CL-)

this will cause the charged ions to move( Na+....same thing to metals because they have +charged ions)...well moving charge is electricity...simple

now lets go to electronics...lets say your cellphone...

if youve seen a computer can notice a lot of thin copper lines(conductor) embedded in a green silicon (semiconductor) in an orderly fashion...

well if water gets into your cellphone...since these chips are well compacted.. too small ... because of the surface tension of the water ,or the water may not have enough force to get contact with the copper lines...most probably short circuit will not happen.

so where does it occur in a cellphone?well the first one to get contact with water.... maybe at the microphone...speaker?hmmm....most probably in the power source.....battery...because it is exposed and simply because its where charge are stored.

if water get into the battery...and if water is a may direct the flow of charge into any direction...if that happens... a lot of current may only pass into one path causing overload....and if that path dont have enough resistance.... heat will build up....and boom short cicuit...
