Can AI help me find a cheaper cell phone plan?
Yes, if you give it your real usage and the plans you're looking at. It compares the total cost over a year, including fees and promo prices that expire.
01Why bot
- Comparing plans is math plus fine print, and AI handles both when you give it the numbers.
- It catches promo prices that jump after 12 months and per-line fees.
- It can't see today's prices, so you paste them in from the carriers' sites.
02The prompt
Replace everything in [BRACKETS] with your own details, then paste it into your AI app.
You are a consumer phone-plan analyst. My current plan and monthly bill: [CARRIER, PLAN, $ PER MONTH WITH TAXES AND FEES] Lines and phones: [NUMBER OF LINES, PHONES PAID OFF OR NOT] My real usage: [GB OF DATA PER MONTH, HOTSPOT, TRAVEL ABROAD] Plans I'm considering, copied from the carrier sites: [PASTE 2-4 PLANS WITH PRICES] Coverage where I live and work: [GOOD OR BAD FOR EACH CARRIER] Your task: find the best-value plan for me. Rules: - MUST compare the total cost for 12 months, including fees and promo prices that end. - MUST use only the prices I pasted; NEVER invent a price or a plan. - MUST flag any contract, device payment or switching cost. - If anything is missing, ask me up to 3 short questions first. Give me, in this order: a comparison table (plan, monthly, 12-month total, catches), your pick in one sentence, and 3 questions to ask before I switch.
03Steps
- Check your last bill and your data use in your phone's settings.
- Copy 2 to 4 plans from carrier websites and paste them into the prompt.
- Confirm the pick with the carrier before you move your number.
04What can go wrong
- Prices change often, and AI only knows what you paste in.
- Switching early can leave you owing the rest of a phone payment plan.
05What to use

06Our test run
Llama 3.3 70B · graded by GPT-OSS 120BSep 29, 2026Passed with a catch
Sample input we used: A typical suburban US customer on Verizon's unlimited plan with two paid‑off phones, moderate data use, and evaluating similar offers from major carriers.
- Compares 12-month totals including fees and promo prices that end
- Uses only the prices the user pasted; no invented price or plan
- Flags contract, device payment or switching costs
- Gives a comparison table (plan, monthly, 12-month total, catches), a one-sentence pick, then 3 questions
What came back (excerpt):
My pick is: The AT&T Unlimited Extra plan offers the best value at $900 for 12 months, with no catches or additional costs mentioned.
Failed check 3 because the answer does not flag any contract, device payment, or switching costs.
One run with an invented sample, checked against the prompt's own rules by a second AI model (word limits counted by code). Your results can differ; how we test.
