13. SMS Retriever API
    For users
    Current flow:
    ● Phone number entered
    ● Phone number sanity checked
    ● Number sent to server
    ● Server sends OTP msg
    ● We create broadcast-receiver
    ● We ask for “Read SMS” permission
    ● We receive broadcast
    ● We pass it to the activity to continue
    Cons:
    ● User takes time
    ● User may make mistakes
    ● User thinks app will read all SMSs
    ● User does not give permission
    ● User does not enter OTP
    ● User leaves app
    ● Project manager is angry, developer is sad
