What Makes a Plan the 'Best'?

The best cell phone plan balances your data usage, coverage needs, and budget. For most people, an unlimited plan from a major carrier costs about $50–$70 per line per month after taxes and fees. A budget provider often offers similar data for $25–$40. Compare total monthly cost, not just the headline price.

No single plan works for everyone. A heavy data user who streams video daily may need an unlimited plan with no throttling, while a light user who mostly uses Wi-Fi can save with a prepaid plan that costs under $20 per month. The key is to estimate your typical monthly data consumption and check coverage in your area before committing.

Postpaid vs. Prepaid: Cost Breakdown

The biggest cost difference comes from the billing model. Postpaid plans (pay after use) from major carriers average $114 per month for a single line, according to the Bureau of Labor Statistics Consumer Expenditure Survey (2024). Prepaid plans (pay upfront) average $39 per month, per FCC data (2025). The gap narrows when you add multiple lines, but prepaid still saves 30–50%.

Plan TypeSingle Line AverageFamily of 4 (per line)Typical Data Allowance
Postpaid (major carrier)$114$45–$55Unlimited (deprioritized after 50 GB)
Prepaid (budget provider)$39$25–$35Unlimited (often capped at 5–15 GB high-speed)

Prepaid plans often have lower priority on the network, which can slow speeds during congestion. However, for most everyday tasks (email, social media, maps), the difference is negligible. Postpaid plans include perks like international roaming and device financing, but those add cost.

Hidden Fees and Taxes

The advertised price is rarely what you pay. Taxes, regulatory fees, and surcharges add 17–25% to the base rate, according to the Tax Foundation (2025). For a $70 plan, that can mean an extra $12–$18 per month. Budget providers often include taxes in the quoted price, making their offers more transparent.

  • Federal Universal Service Fund fee: ~5% of interstate revenue.
  • State and local sales taxes: vary from 0% in some states to over 10% in others.
  • 911 and E911 fees: typically $0.50–$2.00 per line per month.
  • Administrative charges: carriers add a flat fee (e.g., $1.99) to recover costs.

Always ask for the total monthly cost including all fees before signing up. Many budget providers advertise an all-in price, which can be 20% lower than a major carrier's advertised price after fees.

How to Compare Total Monthly Cost

To find the best plan, calculate your total monthly cost for each option. Use this formula: Advertised price + estimated taxes/fees (17–25%) + any add-on costs. Then divide by the number of lines. For example:

  1. Major carrier unlimited single line: $70 advertised + 20% fees = $84 total.
  2. Budget provider unlimited single line: $30 all-in = $30 total.
  3. Major carrier family plan (4 lines): $160 advertised + 20% fees = $192 total, or $48 per line.
  4. Budget provider family plan (4 lines): $100 all-in = $25 per line.

Also consider data speed and deprioritization. Budget providers using a major carrier's network may throttle you after a certain threshold or during peak hours. If you rely on fast data for video calls or gaming, a postpaid plan may be worth the extra cost.

Choosing the Right Plan for Your Usage

Start by checking your current data usage in your phone settings. If you use under 5 GB per month, a prepaid plan with a data cap (e.g., 5 GB for $15) is the cheapest option. If you use 10–20 GB, look for budget unlimited plans that offer 20–30 GB of high-speed data before slowdown. Heavy users (50+ GB) should consider postpaid unlimited plans from major carriers, which typically offer 50 GB of premium data before deprioritization.

Coverage matters more than price. Check the network coverage maps of the two or three largest providers in your area. Many budget providers use the same towers as major carriers, but may have lower priority. If you live in a rural area, a major carrier's postpaid plan may be the only reliable option.

Finally, consider whether you need device financing. Postpaid plans let you spread the cost of a new phone over 24–36 months, often with 0% interest. Budget providers usually require you to bring your own device or pay upfront. If you can afford to buy a phone outright, prepaid saves money in the long run.

Frequently Asked Questions

What is the cheapest cell phone plan available?

The cheapest cell phone plans are from budget providers, often starting at $15–$25 per month for limited data (e.g., 5 GB). Unlimited plans from budget providers start around $25–$30 per month, though speeds may be reduced after a certain threshold.

Do prepaid plans have worse coverage than postpaid?

Not necessarily. Many budget providers (MVNOs) use the same networks as major carriers. However, prepaid traffic is often deprioritized, meaning your data may slow down during network congestion. Coverage in rural areas may be identical if the MVNO uses the same towers.

How much do taxes and fees add to a cell phone bill?

Taxes, surcharges, and regulatory fees typically add 17–25% to the advertised price, according to the Tax Foundation. This can mean an extra $10–$20 per month on a $70 plan. Always ask for the total out-the-door price.

Is unlimited data worth it for light users?

No. If you use under 5 GB per month, a limited-data prepaid plan for $15–$20 is more cost-effective. Unlimited plans are best for heavy data users who stream video or tether frequently.

Can I switch from a postpaid to a prepaid plan without changing my phone?

Yes, as long as your phone is unlocked. Most major carriers will unlock your device after it is paid off. Budget providers typically support unlocked phones. Check compatibility with the new provider's network before switching.
