Adafruit Fona modifications for Teensy 3.1, updated for latest lib + simplified

Fona example file modified for use with Teensy

/* 
 Replace the first lines in your FONATest example file with the lines below. It's basically just changing from SoftwareSerial to HardwareSerial + changed pins to match the Teensy.
 */
#include <SoftwareSerial.h>
#include <HardwareSerial.h>
#include "Adafruit_FONA.h"

#define FONA_RX 1
#define FONA_TX 0
#define FONA_RST 4

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

#define HWSERIAL Serial1
HardwareSerial fonaSS = Serial1; // replaces SoftwareSerial fonaSS = SoftwareSerial(FONA_TX, FONA_RX);
Adafruit_FONA fona = Adafruit_FONA(FONA_RST);

/*
 The example indicates that you should uncomment Serial1 if using HardwareSerial. No need for that.
 
 Next, update Adafruit_FONA.cpp to include HWSerial for the Teensy by putting this at the top:
 */
 
#if (ARDUINO >= 100)
 #include "Arduino.h"
  #ifdef SERIAL_PORT_USBVIRTUAL
    #include <HardwareSerial.h>
  #else
    #include <SoftwareSerial.h>
  #endif
#else
 #include "WProgram.h"
 #include <NewSoftSerial.h>
#endif

/* 
 Lastly, update Adafruit_FONA.h with the same as above. That's it...
 */

I honestly don't remember, haven't touched it for quite a while

I figured it out! I had TX on the Teensy connected to TX on the FONA and same with RX. I just flipped them and it fixed it.
