Sometimes, when you want to send a message or note via Whatsapp, you 'drop' the message to a WhatsApp contact. Either WhatsApp chat to your partner, or to your closest friends. Now, there's no need for that anymore, there's already a 'Message Yourself' WA feature that you can try out for yourself.
These are the steps for sending WhatsApp chats to your own number without having to save the contact first. It's really easy, you know! Just practice it, come on.
How to send WhatsApp chats to your own number using the 'Message Yourself' feature:
Make sure the WhatsApp application on an Android or iOS device is using the latest version
Open the WhatsApp application on the cellphone then tap the Chat icon in the lower right corner
WhatsApp will open a list of contacts and at the very top is your contact with a contact name marker (you)
Under the contact's name, it says 'Send a message to myself'
Select your contact name then type and send the desired message as usual
You can see the chats sent to your own number in the WhatsApp chat list or you can pin them at the top so you don't drown.
Oh yes, all chats that you send to your own number will be visible on other devices connected to your WhatsApp account. Relax, the message is confirmed to be encrypted from end to end.
From now on, if you want to send grocery lists, notes, reminders, and so on, you can directly send them to your own number. No need to send messages to WhatsApp friends or partners anymore. That's how to send a chat to your own WhatsApp number.
