A6 GSM/GPRS Ai-Thinker

[ghasem_eng]

hi.
I bought a GSM/GPRS A6 Ai-Thinker module
(below link:
GPRS A6 module SMS board GSM GPRS wireless data transmission over SIM9 – Inkocean Technologies)

I want to make a simple call with this module and an arduino uno.
I used below wiring between the module and the uno:
GND-A6 ==> GND-UNO
Tx-TTL - A6 ==> PIN 10 digital - uno
Rx-TTL - A6 ==> pin 11 digital - uno

I used the below code in the arduino IDE:

#include <SoftwareSerial.h>
SoftwareSerial a6(10, 11); //Tx,Rx in A6

char phone_no[] = "091248990..";

void setup() {
  Serial.begin(115200);
  a6.begin(115200);
  delay(1000);
  
  /*--------------*/
  code();
  /*--------------*/
}


void code(){
  a6.println("AT");
  delay(1000);
  a6.print("ATD");
  a6.println(phone_no);
  delay(30000);
  a6.println("ATH");
}

but not result has obtained and I couldn't make a simple call from module sim card to phone_number.
please notify me how do I do...
thanks in advance

hello i am new here and i don't seem to able to post a new topic but i hope i can find help
while ago i bought A6 gsm off ebay, see the first image, but i faced lot of issues with it, one , worked great when code uploaded,tested okay but once gets unplugged and tested somewhere else , it doesn't work..i don't know what was up with it , i found it cheaper on ebay and went for it..i am currently stuck on sim900A which is doing great with sms based home automation, however i want to go again for the newly released A6 gsm, upgraded one in the second pic, i want to order in bunch but i wont make a move till i make sure that bug in previous version is fixed....anyone who tried it already , i would like hear if its got any issues relating to sms

my take: these bizarre bugs in these boards is what keeps them cheap..

Thank You and sorry for my English
