I need a mobile App developed- iPHONE or ANDROID
App must send BULK SMS.
I have all phone numbers in EXCEL SPREADSHEETS.... I do not have contacts saved on my phone... App MUST be able to send to all phone numbers on EXCEL SPREADSHEET--- Bidder must say "I understand all project requirements to their fullest extent" so I know you understand everything. This app should not require phone numbers to be saved to send SMS!
I need BULK SMS sent each time (1 SMS to 10,000 phone numbers each time).
