Can customers find out who texted them or who an SMS is from?

No customers are not able to find out who texted them.

Sinch does offer an optional dynamic sender ID, which enables customers to set the number shown on the receiving phone as their company name (to increase brand awareness, recognition and improve trust) or their company number if they choose to, but if someone receives a message and they want to trace who sent it to them, their provider will only be able to trace it back as far as Sinch.
