Boron LTE not connecting to 3rd party SIM

I do, I use the code in the docs, I just change the APN and run it for it to store the credentials.

#include "Particle.h"

#include "dct.h"

SYSTEM_MODE(SEMI_AUTOMATIC);

void setup() {
    Cellular.setActiveSim(EXTERNAL_SIM);
    Cellular.setCredentials("epc.tmobile.com");

    // This clears the setup done flag on brand new devices so it won't stay in listening mode
    const uint8_t val = 0x01;
    dct_write_app_data(&val, DCT_SETUP_DONE_OFFSET, 1);

    // This is just so you know the operation is complete
    pinMode(D7, OUTPUT);
    digitalWrite(D7, HIGH);
}

void loop() {
}

Well, I am looking forward to it! hope it gets here sooner rather than later!

Thank you for your response, regards. :grinning:
