Meeting your friends in an unfamiliar place is a pain. Once you move away from rigid networks, finding a location becomes a challenge. The best thing to do, rather than sharing an address, is to share your exact GPS location. Here's how to do it with WhatsApp.
Open a WhatsApp conversation with the person you want to share your location with, tap the icon and select Location.
The easiest option is just to send where you are right now. Select your current location or one of the nearby place suggestions.
If you plan to travel or if for security reasons you always want someone to know where you are, select Share live location. You'll get a warning ensuring you know you'll be sharing your live location even if you exit the app, so tap continue.
Then select how long you want to share your live location for. The options are 15 minutes, 1 hour or 8 hours. Add a comment if you wish, then press the Send button.
At any time, you can tap Stop Sharing to stop sending your location. Otherwise, until the time expires, they will be able to see your location even if you move somewhere totally different.
