, SMS Forwarding to Multiple Numbers on Code Exchange is a good place philippines whatsapp number to start. What are we building? It's all based on a single Twilio phone number and a group of you and your family or friends who use mobile phones. You can give your Twilio number to other people as if it were your own number. We're going to set up the Twilio number so that any text messages received by that number are forwarded to everyone in your group. I'm going to use two group members in this example, but the code is designed so you can use as many as you want.
Diagram of a phone sending an SMS to a Twilio number, forwarded to two other phones When someone outside of your group (the phone on the left) sends an SMS to the Twilio number, the message is forwarded to everyone in the group (the phones on the right). The messages will appear as if they were sent from the Twilio number, so the actual sender's phone number will be added to the beginning of the message. When a member of your group replies to the Twilio number, they must add the actual recipient's number to the beginning of the message, which will be removed before the message is forwarded.
Everyone in your group also receives a copy of the message: Diagram of one of the phones from the previous diagram responding to the SMS. The message is sent to all participants. Note that if you want to send a message from one group member to everyone else, you can do so by adding your own number to the beginning of the message.
