From the Forums: Control multiple hardware serial or SPI devices on Arduino Zero
Thanks to Kim from the Adafruit forums for posting up about using multiple serial or SPI devices on Arduino Zero
Many people have seen the new Arduino Zero/M0 Pro and this is a good low power chip.
But this only have 1 serial port to connect your serial data devices, Serial1.
But I found a way around it, I got Serial2 to work..
With the use of Serial2 you can now connect something like Adafruit FONA on Serial1 and GPS on Serial2. If you use FONA 808 you don’t need 2 serial ports, but if you only got the 800L you need 2 serial ports, one for FONA and one for GPS.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
