So here's a tips on how you can invoke an action using Activator to enable back location services by sending a message with magic words using other phone.
- Open Activator.
- Tap Anywhere and tap the edit button on top right.
- Tap Received Message.
- Leave alone the 'Sender' and put any magic word on 'Message' (example: I put 'TURNONLOC' as my magic word.)
- Once done back to Anywhere.
- Scroll down and find 'Received Message' and you should see your magic word there.
- Tap on it and choose these (just my recommendation) under 'Switches (Activate)':
- Location Services
- Cellular Data
What it do is whenever your iPhone receive a message with TURNONLOC as one of the word it will activate the action that you choose above. The reason there is no space because if you got a message with let say turn in it, it will activate the action too.
