Building WiFi for Your Farm: Starlink vs. LTE vs. Egg Comparison
Building WiFi for Your Farm: A Complete Guide
I once stood in the middle of a field, phone raised overhead, desperately trying to get one bar of signal. Sending a single message felt like praying to the connectivity gods. But farming has changed. Smart sensors need internet. CCTV cameras need internet. Even figuring out tomorrow’s weather works better with a stable connection. The problem? Farms aren’t exactly downtown Seoul.
Call a telecom company and ask them to install wired internet at your rural farm. The answer is predictable: “We’d need to install new utility poles, and the cost is on you.” That cost can easily exceed 5 million won (roughly $3,700 USD). So most farmers look toward wireless solutions instead.
There are actually quite a few options: Starlink satellite internet, pocket WiFi devices (called “eggs” in Korea) from the big three telecoms, contract-free egg rentals, LTE routers, and traditional wired internet. Here’s a sharp comparison of each.
Starlink: Internet From the Sky
On December 4, 2025, Elon Musk’s Starlink officially launched in South Korea. Thousands of low-orbit satellites circle the Earth over 10 times a day, beaming internet signals down. Plant an antenna, and you’re online—whether you’re on a mountaintop or a remote island.
Starlink Plans (As of December 2025)
| Plan | Monthly Cost | Annual Cost | Data | Speed |
|---|---|---|---|---|
| Residential Lite | ₩64,000 (~$47) | ₩768,000 (~$564) | Unlimited (throttled during peak) | Down ~100Mbps |
| Residential | ₩87,000 (~$64) | ₩1,044,000 (~$767) | Unlimited | Down 135Mbps / Up 40Mbps |
| Roaming 50GB | ₩72,000 (~$53) | ₩864,000 (~$635) | 50GB | Mobile use |
| Roaming Unlimited | ₩144,000 (~$106) | ₩1,728,000 (~$1,270) | Unlimited | Mobile use |
| Business Local 50GB | ₩90,000 (~$66) | ₩1,080,000 (~$794) | 50GB | Priority access |
| Business Local 1TB | ₩405,000 (~$298) | ₩4,860,000 (~$3,571) | 1TB | Priority access |
Initial hardware cost: Standard Kit (antenna + router + cables) ₩550,000 (~$404)
First-year total for the Residential plan: ₩1,594,000 (hardware ₩550K + ₩87K × 12 months). From year two onward, it’s ₩1,044,000 annually.
One farmer who installed Starlink at their farm measured download speeds of 366Mbps—well above the official 135Mbps spec. The antenna even has a “snow melt” mode that automatically heats up when snow accumulates. Pretty handy for outdoor farm installations.
The ₩550,000 upfront cost stings, though. Starlink offers a 30-day free trial, so you can test before committing.
Big Three Telecoms’ Pocket WiFi (Egg): Internet in Your Pocket
Pocket WiFi, or “egg” as Koreans call it, is a palm-sized device with a SIM card inside. It grabs LTE or 5G signals and broadcasts WiFi to nearby devices. No utility poles, no fiber cables—just cellular signal.
Telecom Egg Plan Comparison
| Plan | SKT PocketFi 10 | SKT PocketFi 20 | KT LTE egg+ 11 | KT LTE egg+ 22 | LG 5G egg2 14 | LG 5G egg2 28 |
|---|---|---|---|---|---|---|
| Monthly | ₩16,500 | ₩24,750 | ₩16,500 | ₩24,200 | ₩19,800 | ₩30,000 |
| Annual | ₩198,000 | ₩297,000 | ₩198,000 | ₩290,400 | ₩237,600 | ₩360,000 |
| Data | 10GB | 20GB | 11GB | 22GB | 14GB | 28GB |
| Speed | Max 10Mbps | Max 10Mbps | LTE | LTE | 5G | 5G |
| After cap | Throttled | Throttled | Throttled | Throttled | 5Mbps unlimited | 5Mbps unlimited |
Device costs are separate. KT’s 5G egg2 has a retail price of about ₩407,000, but with subsidies, the actual cost is around ₩200,000. SKT and KT LTE eggs are around ₩120,000.
Honestly, running a farm on a single egg is tight on data. If you’re only pushing sensor data, 10-11GB might work. But add CCTV or video calls, and 20GB disappears in a week. “Data like a mouse tail” (as they say in Korea) isn’t just a figure of speech.
LG’s 5G egg2 offers 4GB per day at full speed, then drops to 5Mbps unlimited. For farms running 24/7 equipment, this isn’t a bad deal.
Contract-Free Egg Rentals: No Strings Attached
If 2-3 year contracts feel suffocating, contract-free egg rental services exist. Notable options include simbank and Alice WiFi.
Contract-Free Egg Cost Comparison
| Option | simbank Unlimited | simbank 10GB | simbank 20GB | Alice Unlimited |
|---|---|---|---|---|
| Monthly (30 days) | ₩59,500~65,000 | ₩16,500 | ₩24,750 | ₩36,000~55,900 |
| Annual | ₩714,000~780,000 | ₩198,000 | ₩297,000 | ₩432,000~670,800 |
| Speed | 20Mbps | LTE | LTE | LTE |
| Network | KT | SKT | SKT | KT/LG/SK |
| Device cost | ₩88,500~135,000 | Free w/ contract | Free w/ contract | Rental or purchase |
Simbank’s unlimited egg stands out: ₩59,500/month for 20Mbps with no daily cap. No contract, no penalty. Months you don’t use it? Zero cost. Perfect for farmers who only need internet during growing season.
First-year total with device: roughly ₩802,500 (device ₩88,500 + ₩59,500 × 12). About half of Starlink’s first-year cost.
The 20Mbps speed is the trade-off. Fine for HD video, frustrating for anything heavier.
LTE Routers: The Smart Farm Workhorse
If your farm has sensors measuring temperature, humidity, and light intensity, and you need remote control capabilities, LTE routers are the real solution. Similar to eggs in principle, but they offer wired LAN ports (RJ45) and static IP addresses—far more stable for IoT equipment.
LG U+ Wireless Internet (LTE Router) Plans
| Plan | Monthly (tax incl.) | Annual | Data | Notes |
|---|---|---|---|---|
| IoT LTE 60MB | ₩4,950 | ₩59,400 | 60MB | Sensor control |
| IoT LTE 1GB | ₩9,900 | ₩118,800 | 1GB | Basic monitoring |
| IoT LTE 11GB | ₩15,840 | ₩190,080 | 11GB (100kbps after) | Smart farm recommended |
| IoT LTE 22GB | ₩26,230 | ₩314,760 | 22GB (500kbps after) | With CCTV |
| Mobile Office Net (Unlimited) | ~₩63,000 | ~₩756,000 | Unlimited (QoS) | 3-year contract |
With a 3-year contract, the IoT LTE 11GB plan drops to ₩13,500/month (before tax). About ₩178,200/year. For sensor-only farms, this is more than enough—daily sensor data rarely exceeds a few hundred MB.
Router devices cost ₩100,000-300,000 separately. Static IP service adds ₩5,000-10,000/month.
Wired Internet: Best Option If You Can Get It
If there are utility poles near your farm and telecom lines reach the location, wired internet is unbeatable value.
Wired Internet Plans (Same Across All 3 Telecoms)
| Speed | Monthly | Annual |
|---|---|---|
| 100Mbps | ₩22,000 | ₩264,000 |
| 500Mbps | ₩33,000 | ₩396,000 |
| 1Gbps | ₩38,500 | ₩462,000 |
WiFi router rental is ₩0-1,100/month. LG is free across all tiers.
Bundle internet + TV through KT Skylife: 200Mbps internet + TV (200+ channels) for just ₩23,100/month. That’s ₩277,200/year—less than a quarter of Starlink’s annual cost.
The catch? Installation in rural areas is the problem. If your farm sits far from existing infrastructure, installing new utility poles can cost millions of won. There’s a “Universal Service” system in Korea that guarantees basic telecom access to all citizens, which may help reduce your installation burden. Worth investigating before giving up.

Which Farm Needs What?
Farms where wired internet installation is possible: No contest. Wired 100Mbps with a WiFi router costs about ₩264,000-277,000/year. Unbeatable value.
Small smart farms with just a few sensors: LG U+ IoT LTE router with the 11GB plan. ₩13,500/month on a 3-year contract. Under ₩180,000/year—almost negligible.
Farms needing CCTV + remote monitoring: You need generous data. LG 5G egg2 28GB (₩30,000/month) or simbank unlimited (₩59,500/month) are realistic options.
Mountain/island farms in dead zones: Starlink is the only answer. When no cell tower reaches you, one satellite dish opens up the internet. ₩87,000/month might feel expensive, but it beats spending ₩5 million on utility poles. First year ₩1.6M, then ₩1.04M annually.
Seasonal farms: Simbank’s contract-free egg is ideal. Pay only the months you use. Six months of use = roughly ₩360,000 for the year.
Practical Tips
- Starlink antennas need clear sky view. Trees or buildings blocking the line of sight will tank speeds. Mounting on top of a greenhouse works well.
- Egg batteries last 6-8 hours. If your farm has power outlets, keep it plugged in. Otherwise, bring a 20,000mAh+ power bank.
- External antennas dramatically improve LTE router reception—essential inside greenhouses where metal frames can interfere.
- Don’t give up if a telecom says installation is impossible. Look into Korea’s “Universal Service” system first. The government may subsidize part of the pole installation cost.
- Starlink offers a 30-day free trial. Buy the hardware, test it, return if unsatisfied.
