Carrier Tier Policy 24-Mo Math Action Verdict
Decoupled Route (iPhone 17 Outright + $34 BYOD Flanker)
Market Benchmark
$979 Unlocked Handset + $34/mo 50GB Plan ($0 Mandatory Airtime Markup)
$1,795 CAD 24-Month Total Spend

Substantial carrier airtime premium for minor generational upgrades.

03. Actionable Decision Framework & Flip Conditions

When Does the Balance Tip?

Coverage & Remote Footprint Priority

Action: If you frequently travel across interprovincial highways or remote rural regions, incumbent networks (Rogers/Bell/Telus) maintain primary physical signal advantages.

Urban Living & Cash Flow Priority

Action: If you commute within major metropolitan corridors, choosing compliant flanker or challenger brands reduces 24-month telecom outlay by $800+.
