This is how to use AI to compare cell phone plans
Plan names hide promotions, device credits, priority data, and fees. Compare the public terms against how the phones are really used.

This is how to use AI to compare cell phone plans.
One carrier says unlimited. Another says premium unlimited. A third lowers the monthly price if you trade in a phone and stay long enough to receive every credit. The names sound comparable, but the conditions live on different clocks.
Use round numbers instead of uploading a bill. Note the number of lines, typical data use, whether devices are already owned, and any travel pattern that truly matters. Then paste the public terms you want compared.
The plan prompt:
Compare these three public plan summaries for two adults who own their phones, use about 18 GB and 9 GB a month, rarely travel internationally, and care about hotspot access twice a month. Plan A is $95 before taxes with 30 GB of priority data. Plan B is $110 with 50 GB and 10 GB of hotspot. Plan C advertises $80 with autopay and a 24-month device-credit condition we will not use.
Normalize the monthly cost, map each feature to our actual use, expose promotion conditions, and list current coverage or fee facts to confirm. Do not name a winner until the missing facts are filled.
Swap in public plan summaries and rounded use. The normalized-cost and condition map is the part that matters.
Level up the ask:
One more move before you send it. Ask this first:
Rewrite my prompt above into a version that will get me a better result. Tell me what you changed and why, then answer the improved version.
Separate service from the sales story
The cheapest advertised plan may not be the cheapest usable plan. Ask AI to remove device credits you will not use, show the cost after promotions, and identify whether a feature solves a real constraint or merely sounds premium.
- Normalize: Put every plan on the same number of lines, billing period, and device assumption.
- Use: Compare priority data, hotspot, roaming, and support only where the household can reach them.
- Confirm: Create a short carrier checklist for fees, coverage, throttling, and promotion rules.
Coverage beats a perfect spreadsheet
A plan is not useful where service is unreliable. Check first-party coverage tools, current terms, and local experience in the places that matter. Read the complete promotion and cancellation language before moving a number or financing a device.
Once the terms are normalized, the tradeoff becomes ordinary: pay for the service you can use, not the plan name with the most impressive adjective.
- Share only: Public plan terms, number of lines, rounded data use, device status, and broad travel needs; exclude phone numbers, bills, account IDs, addresses, and location history.
- Verify: Coverage where it matters, taxes, fees, priority-data rules, device credits, contract terms, roaming, and promotion end dates with the carrier’s current official sources.
