Losing pressurization even suddenly isn't a huge deal by itself. The masks will drop and the plane will go to below 10000 feet but it's unlikely to cause it to crash. There's not enough explosives in the pager bombs to cause catastrophic damage to the airframe or controls.
As a side note it's unclear if it would even trigger in the air because afaik the trigger was immediate when the signal was sent and the pagers shouldn't have signal at altitude just like a cell phone.
