I can see nothing wrong with the code that you did not post

#include “Adafruit_FONA.h”

#define SIMCOM_7000 // SIM7000A/C/E/G

#define FONA_PWRKEY 6
#define FONA_RST 7

#define FONA_TX 10 // Microcontroller RX
#define FONA_RX 11 // Microcontroller TX

// this is a large buffer for replies
char replybuffer[255];

#include <SoftwareSerial.h>
SoftwareSerial fonaSS = SoftwareSerial(FONA_TX, FONA_RX);

buffer size
SoftwareSerial *fonaSerial = &fonaSS;

#ifdef SIMCOM_2G
Adafruit_FONA fona = Adafruit_FONA(FONA_RST);

// Use this one for 3G modules
#elif defined(SIMCOM_3G)
Adafruit_FONA_3G fona = Adafruit_FONA_3G(FONA_RST);

#elif defined(SIMCOM_7000) || defined(SIMCOM_7500)
Adafruit_FONA_LTE fona = Adafruit_FONA_LTE();
#endif

uint8_t readline(char *buff, uint8_t maxbuff, uint16_t timeout = 0);
uint8_t type;
char imei[16] = {0}; // MUST use a 16 character buffer for IMEI!

void setup() {
// while (!Serial);

pinMode(FONA_RST, OUTPUT);
digitalWrite(FONA_RST, HIGH); // Default state

pinMode(FONA_PWRKEY, OUTPUT);

powerOn(); // See function definition at the very end of the sketch

Serial.begin(115200);
Serial.println(F(“FONA basic test”));
Serial.println(F(“Initializing…(May take several seconds)”));

fona.setNetworkSettings(F(“hologram”)); // For Hologram SIM card

fonaSS.begin(115200); // Default SIM7000 shield baud rate

Serial.println(F(“Configuring to 4800 baud”));
fonaSS.println(“AT+IPR=4800”); // Set baud rate
fonaSS.begin(4800);
if (! fona.begin(fonaSS)) {
Serial.println(F(“Couldn’t find FONA”));
while(1); // Don’t proceed if it couldn’t find the device
}

I don’t know what might be the problem can you help me ?

Hi, I know this topic is old, but just in case.
Did you solve the problem? In that case, I'd appreciate you telling me about the solution.

Thanks,

Hi I have a similar problem, I am running SIM7000C and based in NZ. I have a 2-Degrees Simcard on my LTE. It is giving no errors except for:

11:53:57.426 → Timeout: No response to AT… last ditch attempt.

Someone please help
