For a side project I’m currently working on (codenamed Shedwina, more details to follow later) I wanted to set up a Twitter NodeJS bot. On logging into https://dev.twitter.com as my bot account and trying to create a new app I got the error message that the account needed to have a mobile number associated with it. This in itself shouldn’t have been an issue but to set up a mobile number you need to send an SMS to a shortcode… sadly there was no option for EE in the UK and the long number option failed to work even after a few attempts.
I then come up with an idea… and it worked. Basically I installed the official Twitter client on my phone and checked the box which allowed the use of my phone number in the set-up phase. This has the desired affect and upon the next attempt at creating the app over at https://dev.twitter.com all worked like a dream.
