making a simple phone Answered

I'm wanting to make the simplest phone ever that can play music and only receive calls, I've designed the simplest circuit but have never done it before, so far on my list i have.

areal
aux out
charger hole
battery
micro sim slot
micro SD slot
microphone
speaker
6 buttons=

play button
pause button
skip & back up button
receive call 
end/ decline button

i have no idea how to programme a circuit board or how to use a bread board and may need some help, but this is all i want this circuit to do and at a very small size. 
can anyone help or tell me how, I'm happy to pay a bit.

It's highly unlikely you pull this off in this manner given your self admitted knowledge gap. If you really want to make your own phone (which will cost more than a contract free, pay as you go phone) check out the LinkIt One or other GSM enabled development boards. The LEO has the antenna, sim slot, battery, and music/audio hardware and the pre-built code libraries to back them up.

The simplest way to meet your needs is to buy a cheap pay-as-you-go phone and let the credit expire. It will still receive calls and play any music stored on it.

Like Steve and Rick say this is a major design effort.

But you say you have already designed a simple circuit and I'm very curious.

Would you please share the circuit or the parts list.

We can tell you what works and what can be improved if you like.

There is no such thing as a "simple" phone, unless you count the one made with two tin cans and a piece of string. Even the simplest mobile phone is packed with specialised chips which you can't buy.

Your reaching far further than your ability - by your own admission.

You need to start with simple projects and build skills and knowledge until you can do what you want.

Otherwise buy a cheap phone. Even mine will do all those things AND make calls all for less than £30
