How to switch wireless carriers safely

1. Calculate a fair comparison

Use the Switch & Save tool to estimate 12-, 24-, and 36-month costs. Enter your total current bill, remaining phone payoff, one-time expenses, and estimated extra taxes. Compare with prepaid annual charges, mandatory monthly service, and the total cash needed at the start.

Do not automatically count rebates, trade-in offers, or financed-device bill credits until the carrier confirms the full conditions. Compare service and handsets together when a device promotion requires a specific rate plan.

2. Check actual coverage and your phone

Use the FCC National Broadband Map to review modeled coverage and the carrier’s own coverage tools for places you use most. Outdoor maps do not guarantee reception indoors. Ask neighbors or use an inexpensive trial/eSIM when available.

Check your exact phone IMEI and eSIM compatibility with the new carrier. Confirm the phone is unlocked and supports the chosen underlying AT&T, Verizon, or T-Mobile network. A multi-network MVNO may not support every network for every device or plan.

3. Understand offer conditions

Check the actual recurring price after introductory months, required number transfer, taxes, regulatory charges, hotspot cap, deprioritization, roaming, early termination, unlock timeline, annual prepayment, financing, trade-ins and rebate dates. Ask about all charges due before service begins. Carrier-published broadband labels are a useful source for baseline plan information.

4. Transfer carefully

Keep the current service active. Obtain your current account number and a fresh number-transfer PIN from your existing provider. Make sure the line is eligible to port and confirm whether any device balance must be settled. Follow the new provider’s activation and transfer instructions. Do not cancel the old service manually before the number successfully transfers unless your providers explicitly tell you otherwise.

5. Verify the first bill

After activation, inspect the bill and service for the promised rate, discounts, prepaid period, international benefits and fees. Record promotional end dates so you can reevaluate service when the introductory period ends.
