Here's something I've never seen before:
https://www.vodafone.co.nz/samsung-galaxy/galaxy-a01/
https://www.2degrees.nz/shop/mobile-phones/samsung/galaxy-a01
https://www.spark.co.nz/shop/mobile/phones/samsung-galaxy-a01-core.html
The exact same phone, on all three carriers. On Vodafone/2degrees, it comes with 16GB of storage, but the Spark version has 32GB. How does that work? Is this a common thing?
Like I said...never seen this happen before.
