I'm working in a web application and it has to include some send SMS feature; I'm planning to create an Android Application and use it to send SMS taking data from the server. The customer asked if the phone number can be hidden, I really couldn't answer the question; So that's pretty much my research this days. How hiding the phone number from a SMS works? Is it something with the provider or can the SMS number really be hidden or spoofed?
Greetings.
Usually this is done by the SMSC. There are several online services that allow you to specify a "sender" value. This could be a word, rather than a number. Some companies, like banks do this (i.e: "Citibank", "HSBC", ...).
For example, using a popular SMS service such as Twilio, they allow you to set the sender ID, number or word. Obviously with necessary restrictions.
When I had to do something similar but on a more theoretical level I used something similar to this http://www.thebitbag.com/how-to-hide-your-phone-number-when-sending-a-text-message-on-your-phone/80814 but i think your best bet would be calling your provider.
P.s cant create a hyperlink for some reason, sorry
Actually another option is to send MMS - you can add the header X-Mms-Sender-Visibility and set it to hide (0x80) if you can craft the PDU.
