Overview
The Telecom Cost Comparison Calculator helps optimize your monthly phone bill by comparing plans from Korea's three major carriers (SKT, KT, LG U+) and budget carriers (MVNOs). It calculates actual monthly payments by considering data usage, call minutes, contract discounts, and device installment payments.
Formula
Total Monthly Bill = Plan Base Fee - Contract Discount + Device Installment Contract Discount: Subsidy method (device discount) or Elective Commitment (25% off monthly fee) Example: Plan KRW 69,000 - Elective Commitment KRW 17,250 + Device KRW 35,000 = KRW 86,750/month
How to Use
- 1Select a carrier (SKT, KT, LG U+, or MVNO).
- 2Enter your required data and call minutes.
- 3Enter the contract type (device subsidy or elective commitment) and device installment amount.
- 4Click Calculate to see your monthly payment and 2-year total cost.
- 5Compare different plans to find the optimal combination.
Tips
- ✔Budget carriers (MVNOs) use the same networks as major carriers but can save KRW 10,000-30,000 per month — up to KRW 120,000-360,000 annually.
- ✔Compare two contract options: device subsidy (discounted phone price) vs. elective commitment (25% off monthly fees) to choose the better deal.
- ✔Check if you truly need an unlimited data plan. If your actual usage is under 10 GB/month, a mid-tier plan may suffice.
FAQ
Q. Is MVNO call quality different from major carriers?
MVNOs lease networks from SKT, KT, or LG U+, so call quality and data speeds are essentially the same. However, some MVNOs may have reduced speeds during peak hours, and they typically have fewer physical stores for customer support.
Q. What is the early termination fee for canceling a contract?
The penalty depends on the remaining contract period. For device subsidies, you must return a prorated amount of the subsidy. For elective commitments, you pay a percentage of the remaining discount period. The penalty decreases as the contract nears its end.
Q. How do I switch carriers while keeping my number?
Mobile Number Portability (MNP) lets you keep your existing number when switching carriers. Simply request number porting when signing up with the new carrier — no separate cancellation with the old carrier is needed. You will need valid government-issued ID for identity verification.
Q. How much can I save with a family bundle discount?
Family bundle discounts vary by carrier but typically offer KRW 5,000-25,000 per line per month depending on the number of lines. Additional discounts apply when bundled with internet and IPTV services. A family of four can save approximately KRW 30,000-100,000 per month.
