How Does Mobile Billing Work? Postpaid vs. Prepaid & Autopayment Setup

Understanding Mobile Billing: Postpaid vs. Prepaid
Whether you're on a postpaid or prepaid mobile plan, understanding how billing and payments work is crucial to avoiding late fees, maintaining good credit, and keeping your phone service active.
This guide breaks down how billing works for postpaid and prepaid plans in Canada and how you can set up autopay to make life easier.
How Does Billing Work for Postpaid Plans?
A postpaid plan means you pay at the end of the billing cycle based on your usage.
Postpaid Billing Cycle: What to Expect
- Billing Cycle Starts: Your plan renews on a fixed date every month.
- Usage is Tracked: Calls, texts, and data usage are monitored.
- End of Billing Period: A bill is generated based on your plan and any extra charges.
- Payment Due Date: You usually have 2 to 3 weeks to pay before late fees apply.
Postpaid Bills May Include:
- Base plan cost (e.g., unlimited data plan for $75/month)
- Device financing payments (if you’re paying off a phone)
- Additional charges (e.g., international calls, extra data)
- Taxes & fees (varies by province)
Key Takeaway: Postpaid plans give you a fixed monthly bill, but extra usage or international roaming can increase your charges.
How Does Billing Work for Prepaid Plans?
A prepaid plan means you pay upfront before using the service. There are no surprise bills or extra fees as you only use what you’ve paid for.
Prepaid Payment Cycle: What to Expect
- Recharge Your Account: You purchase a plan for 7, 30, or 90 days in advance.
- Usage is Limited to What You Paid For: Once your balance runs out, you need to top up to continue service.
- Plan Renews (if Autopay is On): If you enable autopay, your prepaid plan renews automatically.
Prepaid Bills May Include:
- Fixed data, talk, and text allowances
- Add-ons (e.g., international calling, extra data packs)
- No overages, just a pay-as-you-go model
Key Takeaway: Prepaid plans offer 100% control over spending - no contracts, no overages, and no credit checks.
How to Set Up Autopayment for Postpaid & Prepaid Plans
Setting up autopay ensures you never miss a payment, avoiding service disruptions and late fees.
How to Set Up Autopay for Postpaid Plans

How to Set Up Autopay for Prepaid Plans
Many prepaid carriers allow automatic top-ups to keep your service running without manually reloading your balance.
Steps to Enable Autopay (Prepaid)
