Hello I have a Neoway M590 wired and running through a logic level converter wired to my nano but it is still giving me rubbish. On occasion the occasional line will be legible and so is the occasional letter. Please can you guys help

Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Thanks... Tom... 
Thanks for responding I have fixed my initial problem it was my logic converter and i have switched to a voltage divide working ok. Now all I want is for me to text the number and a servo to move depending on the input. I found the code and have altered slightly but it doesn't engage the servo. I think the code is trying to ready the sms messages from storage but the sms is displayed in the serial monitor. Ideally I need it to just go he that says open move servo. I will appreciate any help.
