Terrible documentation

Warning this is made in China so the documentation is terrible. The only script that works with Waveshare is the PWRKEY toggle script. Scripts for SMS and calls do not work. GPS takes longer than advertised "3-5 minutes"; at least in hawaii. The documentation for downloading and obtaining the GPS EPO file does not work and does not help speed up GPS fix times. Currently with a Tracfone prepaid SIM that works on the phone for calls, SMS and data up to LTE.

Pros
