There are a few things you need to know if you want to chat with your girlfriend on WhatsApp. First, make sure that your phone is up to date with the latest security patches. Second, be sure that your WhatsApp account is set up properly - it’s not recommended to use a phone number that’s been blocked by your carrier. Once you have all of these things in place, it’s time to start chatting! To start a conversation on WhatsApp, simply send her a message with the subject line “CHAT!” and she will respond with her own message. You can also use the “send” button at the bottom of each message to send her a copy. If you’re having trouble getting through to her, don’t hesitate to reach out for help! There are plenty of people who can help you out on WhatsApp - just type in “help” at the top of the screen and they will guide you through setting up your account and starting conversations.
