you need usb gsm modem, it comes with software.
you insert sim and attch to usb and pop its software in windows and send bulk sms.
previously it used to work when phones used to support AT commands , but i guess androids/ios doesnt support AT commands.
OR
you need old phone which supports AT command, connet to ur PC and there are bulk sms sending apps which make use of your phone .
