There are a couple ways to share your location, but this might be the quickest! Here's how to share your location from your iPhone in a text message using predictive text. For this tip, you'll have to have both Predictive Text and Location Services enabled. And if you're not connected to Wi-Fi, you'll have to enable Apple Maps too.
How to Share Directions in Apple & Google Maps
If you're meeting up with someone in a large area like a park or can't talk on the phone to give directions, sharing your location in a text message can really help! To do this:
Open a new or previously opened text chat with the person you want to share your location with.
- Type the phrase "I'm at" and press the spacebar after the word "at".
- In the predictive text area of the keyboard, tap Current Location.
- The other person will be sent your location via Apple Maps.
- Notice that only the map will show up in the text chat. You'll need to press the blue arrow to send the text message you've typed.
