Simplicius apparently attended the Council of Turin which probably took place in either 398 or 400.Gregory of Tours cites a lost letter of Paulinus of Nola (died 431)^[4] as having praised Simplicius, considering him "one of the most worthy bishops of his time".

His feast day is celebrated on 11 February.
