Mobile Betting There are more mobile phones connected to the internet than computers globally. Recent studies have shown that 91% of the adult population has access to a mobile device. In fact, more people have a cell phone than a toilet, which is a staggering statistic. Numerous bookmakers have stated that mobile betting now accounts for a big percentage of their overall turnover. That trend will also continue, as mobile sports betting apps now rival sportsbook websites plus more players globally have internet-enabled devices.
