Arduino SIM900 No SMS received I tried the tutorial in this link

https://lastminuteengineers.com/sim900-gsm-shield-arduino-tutorial/

to send an SMS message using a SIM900 GSM shield

I completed the section to send AT commands successfully but I can't get
the Arduino Uno to send an SMS. Below is the output I get after doing AT command tests

Initializing...
AT

OK
AT+CPIN?

+CPIN: READY

OK
AT+CSQ

+CSQ: 6,0

OK
AT+CCID

8944500105191448516F

OK
AT+CREG?

+CREG: 0,5

OK
AT+COPS?

+COPS: 0,0,"T-Mobile "

OK
AT+COPS=?

+COPS: (2,"T-Mobile ","T-Mobile ","310260"),,(0,1,4),(0,1,2)

OK


and below are the responses from the SMS code

Initializing...
AT

OK
AT+CMGF=1

OK
AT+CMGS="+1mycellphonenumber"

so no response from the AT+CMGS command and NO SMS received. 
Plug is 5V 2A.

Any idea what might be causing the issue?

Below is the code I used for the Setup() function 

void setup()
{
  //Begin serial communication with Arduino and Arduino IDE (Serial Monitor)
  Serial.begin(9600);

  //Begin serial communication with Arduino and SIM900
  mySerial.begin(9600);

  Serial.println("Initializing..."); 
  delay(1000);

  mySerial.println("AT"); //Handshaking with SIM900
  updateSerial();

  mySerial.println("AT+CMGF=1"); // Configuring TEXT mode
  updateSerial();
  mySerial.println("AT+CMGS=\"+ZZxxxxxxxxxx\"");//change ZZ with country code and xxxxxxxxxxx with phone number to sms
  updateSerial();
  mySerial.print("Last Minute Engineers | lastminuteengineers.com"); //text content
  updateSerial();
  mySerial.write(26);
}
Changed my SIM card to Ting from Hologram and it worked just fine!
