Fake caller ID on text messages using Twilio (or any other provider)
问题 Simple question: How can I send a text message using Twilio, or any other provider, with fake caller ID? I'm using Twilio REST API (C#). EDIT: I found this company which provides this future, but they are far too pricey: http://www.smsmessagesender.com/SmsApi Does anyone knows a better alternative? 回答1: For the most part, it's a carrier thing. In the US, generally speaking, any SMS traffic has to be from a number you 'own'. For APIs, that would be one or more virtual numbers you purchase.
