What to know
Mobile: what to know
SIM-only is the airtime, not the phone
You keep your handset, so the monthly price is usually lower than a plan that also pays off a new phone.
Data matters more than speed
For everyday browsing and streaming, the allowance is the number to check. Speed matters mostly on 5G plans.
Read the second price
Many deals start low, then step up. The real monthly cost averages the lot, fees included.

Quick answers
What is the difference between SIM-only and a phone contract?
SIM-only is just the airtime plan. You keep (or buy separately) your handset, so the monthly price is usually lower than a plan that also pays off a new phone.
What does Mbps mean, and do I need it for a mobile plan?
Mbps (megabits per second) measures data speed. For mobile it mostly matters on 5G plans; for day-to-day browsing and streaming, the data allowance matters more than raw speed.
Why do some plans show a price that changes after a few months?
Many deals start with a discounted intro price for a set number of months, then move to a higher standard price. We rank by the real monthly cost across the whole contract, and each card has a breakdown showing both figures.
