I want to create my own text messaging server without using someone elses API's. I need to make my own one because I am expecting a lot of users and don't think these third party API's are realiable or fast enough.
How would I go about doing this?
For example, how would i contact a network provider and ask them to set this up
Will they give me an api for the web?
how much will it code?
what hardware will i need
