I'm looking at getting a Lumia 635 for Dad for Christmas, and I notice that Noel Leemings have both Spark and Vodafone flavours of this handset, for $299, and $199 respectively.
Dad is currently on Spark prepaid, and I know he's keen to stay with Spark.
Is there a good reason not to buy the cheaper Vodafone variant, and just swap out his existing Spark SIM?
