Fido recently made a slight change to the prices of their Value Packs and Caller ID. The Fido website was quietly updated about a week ago with increases of $1 to Value Packs and Caller ID. Value Packs are now stand at $11 and $16, whereas Caller ID as a standalone feature is now $8 per month.
It was only ten days ago Rogers/Fido prepaid data passes experienced a similar increase in pricing.
On an interesting side note, Fido appears to be marketing a new $25 Unlimited After Work Plan, which is essentially their $25 standard plan.
