Hello, this is Nakagawa from the association.
“I watched too much YouTube and my internet slowed down at the end of the month…”
Have you had this experience?
Watching videos and using SNS on your phone is one of life’s daily pleasures.
But running out of data is really inconvenient.
With LP Mobile’s 100GB plan, that worry disappears!
📱 How Much Data Does the Average Person Use in Japan?
People living in Japan average about 12–15GB per month.
But if you watch lots of video or use SNS often, you’ll need much more.
■ You need a lot of data if you…
- 🎥 Watch YouTube 1–2 hours daily → about 30–60GB/month
- 📱 Watch TikTok often → about 1GB per hour
- 📸 Watch Instagram videos/reels often → about 1–2GB per hour
- 🎮 Play online games → more than 10GB/month
- 📹 Do daily video calls (LINE, Zoom) → about 1GB per hour
- 🏠 Have no Wi-Fi at home → all data on phone
⚠️ Do any of these sound familiar?
“At month-end, videos just won’t play…”
“Bought extra data and the bill went up again…”
“Every month I watch remaining data anxiously…”
That means your plan’s data allowance is too small!

📊 What Can You Do With 100GB? [Easy Calculation]
Here’s how much you can use if you have 100GB per month.
■ What 100GB gets you (per month)
| App / Usage | Estimate for 100GB |
|---|---|
| 📺 YouTube (standard quality) | About 150 hours (5 hrs/day) |
| 📺 YouTube (HD) | About 90 hours (3 hrs/day) |
| 🎵 TikTok videos | About 100 hours (3–4 hrs/day) |
| 📸 Instagram (video/reels) | About 50–100 hours |
| 📹 LINE video calls | About 100 hours (3 hrs/day) |
| 🌐 Web browsing | About 60,000 pages |
| 🎵 Music streaming | About 25,000 songs |
👉 Even with 3 hrs of YouTube + 1 hr of TikTok + 1 hr of Instagram every day, 100GB is plenty!
🏆 Other Carriers Don’t Offer 100GB?!
Let’s compare with Y!mobile and UQ mobile.
| Carrier | Max data | Fee (tax incl.) |
|---|---|---|
| Y!mobile | Up to 35GB | ¥5,258 |
| UQ mobile | Up to 35GB | ¥3,828 |
| LP Mobile (Z Plan) | 100GB ★ | ¥4,378 |
💡 Nakagawa’s calculation
Y!mobile: 35GB / ¥5,258. LP Mobile: 100GB / ¥4,378.
→ LP Mobile is ¥880 cheaper AND has about 3× more data!
Y!mobile and UQ mobile don’t even offer plans above 35GB.
For heavy video users, LP Mobile wins clearly.
⚠️ Honest Note About Limitations
LP Mobile’s Z Plan is very cost-effective, but let’s honestly cover the caveats.
■ About the 3-day limit (on standard plans)
- On standard plans, using more than 5GB in 3 days can cause slight speed reduction
- This is a common rule across many budget SIMs
- Plenty for normal daily use
✅ Good news!
The Z Plan has no 3-day / 5GB limit!
You can use lots of data every day with peace of mind.
■ About peak-hour congestion
- ⚠️ At lunch (12–13) or evening (18–19), connection can be slightly slower
- ⚠️ True for LP Mobile and most other budget SIMs too
- ✅ Morning and night usually feel fast
■ Compatible smartphones
- ✅ Need a SIM-free phone
- ✅ Must be compatible with DoCoMo’s network
- ✅ Phones brought from abroad often work if SIM-free
- ⚠️ If unsure, ask LP Mobile support before signing up
