Based on @shanghongsim's research, best to use an african phone number, to avoid international charges when using twilio within africa

it turns out we can only use a Canadian or US number for the free trial phase on twilio. i got around the initial challenges so i am now looking into this issue.
These are the numbers i am working with.
Twilio number: "+17206064496",
Local number: "+256775988603"
i will look into purchasing an upgrade with time
