Virtualwire and Gsm not working together

[vinspatil]

I am using RF module and Gsm module in my project. I am able to get working them independently but not together. When I comment virtual wires initialisation in setup gsm code works perfectly, when I un comment there is no any compilation error but gsm don’t receive messages. Please , help thank you.

How are they wired?
Where’s your code ? (in code tags).

#include <VirtualWire.h>

#include <SoftwareSerial.h>               

#define RX  10
#define TX  11

Sim800L GSM(RX, TX);

char* text;
char* number;

double alpha = 0.75;

int TX_PIN = 2;
int TX_ID = 3;

 typedef struct roverRemoteData

  int TX_ID;

  void setup() {
    Serial.begin(9600);
    
vw_setup(2000);

pinMode(buzPin,OUTPUT);

}

void loop() {

  static double oldValue = 0;
  static double oldChange = 0;
  int rawValue = analogRead(input_pin);
  double value = alpha * oldValue + (1-alpha) * rawValue;
  Serial.println(rawValue);
  oldValue = value;
   delay(period);

  struct roverRemoteData payload;

  payload.TX_ID = TX_ID;
  payload.Sensor1Data = rawValue;

  vw_send((uint8_t *)&payload, sizeof(payload));
  vw_wait_tx();

if (rawValue > highLimit) {
  digitalWrite(buzPin,HIGH);
}
else {
  digitalWrite(buzPin,LOW);
}
if (rawValue < lowerLimit) {
  GSM.begin(4800);
  text="EMERGENCY! Swimmer almost dying!!";
  number="+254123456789";
  error = GSM.sendSms(number,text);
}
}
