the $22maud reflects digicel's guaranteed minimums not necessarily all sales.
overall I'd say the scope for $100m aud in sales contracts being inked this financial year is probable - though that would include 3 years rolling income
almost certainly i would expect $20-30m aud in sales revenue in fy18 alone - at 30x price/sales assuming full dilution would indicate $400-600M mkt cap - though market will look to see how momentum goes - esp around data sales
if momentum continues rising then you'd get fy19 starting to be priced in
