Dual-SIM phones

If you are using a dual SIM phone, Tracker texts will only work correctly if your phone is configured to set up to send and receive text messages from SIM1. Unfortunately in Android there was no official dual-SIM support so this is all manufacturer specific.

Android power-saving

Android phones like to have "power saving" settings where they cull perfectly valid apps running in the background or when not being viewed. It is important to check that Tracker is excluded from your phone's power saving settings, or turn this off (along with any "power saving" of GPS and data).
