Trim Your Phone Bill and Subscriptions to Save 100,000 Won a Month

Saving 100,000 won a month is realistically achievable simply by restructuring your mobile plan and cutting duplicate subscriptions. According to Statistics Korea household spending data, the average household spends around 100,000 won per month on telecom, and when OTT and membership subscriptions overlap, the combined total often reaches 150,000–200,000 won. Cutting 50–60% of that spending makes the 100,000-won goal add up in real numbers.

Where the Money Leaks: The State of Fixed Expenses

The Single-Household Era: Telecom Bills Are a 50,000–100,000 Won Fixed Cost

Now that single-person households account for over 35% of all households, telecom bills are the easiest expense to reduce — and the most neglected. The three major carriers' 5G plans run 50,000–100,000 won a month, and adding wired/wireless internet and TV tacks on another 30,000–50,000 won.

The Subscription Economy Trap

OTT services and memberships look affordable at 5,000–20,000 won each, but when Netflix, YouTube Premium, Melon, and Coupang memberships pile up, the total balloons to 50,000–100,000 won a month. With more than half of adults estimated to use subscription services, duplicate spending is a structural problem.

Internet and TV Bills That Jump After Promotions End

The trap in internet and TV pricing appears when the contract ends. Many households keep paying full undiscounted rates — a classic case of 'paying for what you don't know.' The contract expiry date is a savings opportunity.

Cutting Telecom Costs: Rethinking Your Plan Is Half the Battle

Check for Overkill 5G Plans

Many users hold unlimited plans while actually using only 5–20GB a month. Simply checking your data usage over the past three months and downgrading to a lower-tier plan can save 20,000–50,000 won a month.

Switching to an MVNO: Save 40,000–60,000 Won a Month

A user on a major carrier's 5G plan (70,000–90,000 won a month) who switches to an unlimited-data MVNO plan (in the 20,000–30,000 won range) can cut costs by 40,000–60,000 won a month. However, restrictions may apply if your device isn't unlocked, so check your device contract status first. Heavy callers may find it better to stay with a major carrier — factoring in MVNO quality and add-on limitations — and instead use family bundles and long-term customer discounts.

Renegotiating Internet and Cutting Lines

For internet and TV, notifying customer service of your intent to cancel one to two months before your contract expires often triggers discount offers comparable to those for new subscribers. If you barely watch TV, you can drop the IPTV base fee and switch to an internet-only plan (in the 20,000–30,000 won range). Canceling add-on calling options or an unused second line saves another 10,000–20,000 won a month.

Sorting Out Subscriptions: Criteria for Keeping or Cutting

Cancel Anything Used Fewer Than Twice a Month

Gather all recurring payments from your card statements and auto-transfer records, then evaluate based on actual usage over the past three months. Just applying the rule of canceling services used fewer than twice a month and keeping those you genuinely use even once a month filters out one to three items in most households. Major OTT services like Netflix allow cancellation on the web within two minutes, with access continuing until the billing date. Remember: deleting the app is not the same as canceling.

Lower Per-Person Costs Through Sharing, Bundling, and Annual Payments

For services you keep, family sharing plans can cut individual costs by more than half. Some carrier memberships include OTT discounts, allowing you to capture bundling benefits. If you use a service consistently, annual payment can save 15–20% on a monthly basis. Note, however, that major OTT services are tightening household-based restrictions, so check the sharing terms.

Savings Simulation and Action Roadmap

The 100,000 Won, Verified in Numbers

Assume a household with a 5G unlimited plan, IPTV, and three OTT subscriptions. Spending of 160,000 won a month drops to 58,000 won: an MVNO unlimited plan (25,000 won), internet-only service (25,000 won), and one OTT with family sharing (8,000 won). Savings exceed 100,000 won a month. In a conservative scenario — staying with a major carrier and only tidying up subscriptions — the ceiling is around 55,000 won a month: 20,000 won from downgrading the plan, 15,000 from canceling TV, and 20,000 from trimming subscriptions. The conclusion is clear: trimming subscriptions alone won't get you to 100,000 won a month; you need to actively redesign your telecom spending.

A One-Month Action Plan

In week one, compile all telecom bills and recurring payments into a single list and measure the gap between current spending and the 100,000-won target. In weeks two and three, execute plan changes, internet renegotiations, and subscription cancellations. Most of these can be handled online yourself without fees. In week four, verify actual savings on next month's bill, and route the saved 100,000 won into savings and investment accounts first via automatic transfer. As financial advisors commonly stress, cutting back on contracts delivers far more lasting benefit than cutting back on coffee.

Cautions Before You Act

Check Early Termination Fees and Quality Trade-offs

Canceling mid-contract incurs termination fees ranging from tens of thousands to hundreds of thousands of won. Check your expiry date, compare the remaining penalty against future savings, and only then switch. Also check whether porting your number wipes out coupons or benefits from your current carrier. When switching to an MVNO, reduced call quality and fewer add-on services like roaming are costs you must accept.
