Prepare the header strip:
Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down
Add the breakout board:
Place the breakout board over the pins so that the short pins poke through the breakout pad
Be sure to solder all pins for reliable electrical contact.
(For tips on soldering, be sure to check out our Guide to Excellent Soldering).
A battery, GPS antenna and GSM antenna is required! Use any Lipoly or LiIon 3.7V/4.2V battery
Check polarity for the battery!
Snap the uFL connector on, it will click when placed properly
You must insert a SIM card to do anything but the most basic tests. GPS does work without a SIM but of course you cannot send or receive texts, calls, etc!
The SIM card holder is on the back. It holds a very-standard "Mini SIM"
Micro SIMs will not work! Make sure you get a "Mini SIM"
