GSM SIM900 Getting SMS not in text format.

Using Arduino Project Guidance

hi there , i am trying to get SMS into GSM shield sim900 , from a gps tracker

i am getting SMS from my smart phone nice , but from the GPS tracker i get somethng like this

006C00610063003A003700340020000D000A006300690064003A00370031003300320020000D000A006D00630063003D00320030003200200020000D000

is this hex format.?

i expect something like

lat:39.97018 long:24.75841 speed:001.8
T:04/14/16 10:32
http://maps.google.com/maps?f=q&q=39.97018,24.75551&z=16

(in my mobile phone , the tracker send the SMS as it should)

i am using this library GitHub - MarcoMartines/GSM-GPRS-GPS-Shield: GSM/GPRS & GPS Shield Library for modules using SIM900/SIM908

#include <SoftwareSerial.h>

 #include "SIM900.h"
 #include "call.h"
 #include "sms.h"
 SMSGSM sms;
 CallGSM call;

char phone_number[20];
char sms_text[160];

...........

loop(){
sms.GetSMS(20, phone_number,20, sms_text, 160);  
Serial.println(sms_text);            
 Serial.println(phone_number);
}

i guess is library related..

Hardware
Arduino mega 2560
GSM GPRS Sim900

this is PDU format?, is there any encoder for arduino in order to understand this encoding?

The hex translates into:

lac:74

cid:7132

mcc=202

This is not from the GPS but the GSM Shield, although it could probably be used to find approximate location.

Could you paste more output from the GSM Shield?

this is the message from the tracker yes there is more info that i didnt post.

how can i convert it on the fly into a readable text from arduino when this arrives?

except that, that message is the 1/2. The rest is not received!!!!
