Can I Make SMS Messages Appear From Different Users?

One approach could be to create a mobile app for your users. They would install this app, and when an SMS needs to be sent, you could send a notification to the app with the SMS content and the recipient's number. Then, the actual SMS would be sent from the user's device, which eliminates the issue of appearing as one fixed number. It might be a bit tricky to get right, but it could work!

It's worth checking with your SMS provider; it is technically possible since some scam callers do SMS spoofing. Legalities are another story, though. You need to be cautious, as spoofing can lead to lots of issues, including potential legal problems.

I'd be cautious with this. While technically possible, making SMS appear from different numbers is complicated. Carriers generally don't allow changes to the originating number without specific contracts. Plus, SMS delivery isn't guaranteed, and spoofing can lead to messages being dropped by carriers. It’s often better to just include the user's number in the message content so it’s clear who triggered it.

Just a heads up, but Twilio doesn't support SMS spoofing, and it could be illegal depending on where you're located. Some companies may have offered it in the past, but that market has certainly dwindled.

It's usually not possible to send SMS from arbitrary numbers unless you have a contract with the SMS operator. Even then, it raises concerns about validation and could open the door for spoofing by users, which isn’t ideal. A better solution may be to simply indicate in the message content who triggered the SMS, ensuring clear communication without the risk.
