I think IsMatch is better if we want an "all digits" validation - some expressions that include -+ or purhaps even ( can still be numeric. https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-ismatch

Must be IsMatch which allow for regular exp, IsNumeric will validate "1.00" as true and phone numbers don't have decimal.
