I would like to have suggestions from you
In My application i want to read a received SMS from a Mobile and take decisions on the received message and send some sensor values as an SMS to the user mobile... I have some questions on that;
1)which will be easy to implement either to go for a mobile phone which supports
AT Commands or can go with this mobile Nokia 3310 with your procedure?
2)Is it possible to successfully implement this in your procedure ie;imean without AT Commands.
Leave me your suggestions please...

It is simplest with AT command phone!
this is the site for that

Nokia phones(3310) use FBUS as we already know

I found it quite difficult to implement it bcos
there isnt much proliferation for the same
But thats why i wrote this tutorial

It is li'll difficult to send sms via
micro.It will require preset sms and/or
eeprom..
I have completed a commercial project and will be up for sale shortly which does your above mentioned
task (with AVR micro)
which micro r u using?

summing up,u can take this phone(3310)
and complete the project quite easily
if u want help,i m there
