I am C# programmer. i have a client who has asked me make a server that can 100,000 SMS per 5 - 10 mins.
So, i am asking you guys could you give me a suggestion that how should do it?
1) Either find and online web site that provide me this service?
2) Make my own SMS server using GSM modems and computer servers?
or any other better approach that i can use?
Thanks in advance.
