If you use LINE to communicate with friends and family in Japan, LINEMO's "LINE GigaFree" feature might sound too good to be true. Free LINE usage that doesn't count against your data? Video calls that work even when you've run out of data? This comprehensive review reveals exactly what works, what doesn't, and whether LINE GigaFree lives up to the hype.
What is LINE GigaFree?
LINE GigaFree (LINEギガフリー) is LINEMO's signature feature where LINE app usage does NOT consume your monthly data allowance.
According to LINEMO's official website: "LINEご利用分については、月間データ通信量を消費することなく、使い放題（データフリー）でご利用できます" — LINE usage operates as unlimited data without consuming your plan's capacity.
The Key Benefit
The real power of LINE GigaFree reveals itself when you've exhausted your monthly data limit. Even when your phone throttles other apps down to sluggish 300Kbps or 128Kbps speeds—making web browsing painfully slow and Instagram nearly unusable—your LINE communication speed remains completely unrestricted. This means you can still make crystal-clear video calls, send photos instantly, and chat on LINE exactly as if you had unlimited data. For anyone who relies on LINE to stay connected with family, friends, or colleagues, this effectively removes the anxiety of running out of data mid-month.
What's Included in LINE GigaFree (Data-Free)
Understanding exactly what LINE GigaFree covers is crucial for managing your data usage effectively. The feature broadly covers most core LINE communication functions, but there are some notable exceptions that catch users by surprise.
Fully Covered Features (Zero Data Consumption)
All the essential communication features you probably use LINE for are completely data-free. Text messaging and chat obviously use no data, but the coverage extends far beyond simple text. Voice messages, stickers (both sending and receiving), and file transfers—including images, videos, and documents—all consume zero data from your monthly allowance.
Where LINE GigaFree truly excels is with calls. Both voice calls (audio only) and video calls work without consuming any data, whether you're on a one-on-one call or participating in group video conversations. Even advanced features like screen sharing during calls are covered. This is particularly valuable because video calls normally consume significant data—a one-hour video call might use 500MB to 1GB on a regular plan, but with LINE GigaFree, it's completely free.
The coverage also extends to LINE's social features. Viewing, posting, and sharing on LINE VOOM (formerly Timeline) doesn't count against your data. Profile management, adding and managing friends, and accessing albums and notes within your conversations are all data-free.
Features with zero data consumption:
- Text messages, voice messages, stickers
- File transfers (images, videos, documents)
- Voice calls and video calls (individual and group)
- Screen sharing during calls
- LINE VOOM viewing, posting, sharing
- Profile and friend management
- Album and note access within conversations
Features That Still Use Your Data
While LINE GigaFree covers the core communication features, several LINE functions do consume your regular data allowance. Location sharing within chats uses data—this makes sense since it's pulling real-time map data from external services. Browsing the LINE Sticker Shop consumes data, though sending stickers you've already downloaded remains free.
LINE's content services fall outside the GigaFree coverage. Reading news articles within the LINE app, streaming LINE LIVE broadcasts, and using LINE family services like manga readers, games, LINE Music, or LINE points all consume your regular data. When you navigate to third-party websites from links within LINE, or use paid services within the app, those activities use your standard data allowance.
Features that use your data:
- Location sharing
- LINE LIVE streaming
- Sticker Shop browsing
- News article reading in LINE
- LINE family services (manga, games, LINE Music, points)
- Third-party website links
- Paid services within LINE
Technical Limitations You Should Know
LINE GigaFree works seamlessly for most users, but there are a few technical configurations that can interfere with the service, particularly for iPhone users.
iOS Users: Private Relay Configuration
If you have an iPhone running iOS 15 or later and you've enabled iCloud+ with Private Relay, LINE GigaFree will not work properly. Apple's Private Relay feature encrypts and routes your internet traffic through multiple servers, which prevents LINEMO from identifying LINE traffic as eligible for the data-free benefit. The fix is straightforward: go to Settings → Apple ID → iCloud → Private Relay and turn off Private Relay. Once disabled, LINE GigaFree starts working immediately.
Other Potential Interference
VPN usage may also interfere with LINEMO's ability to identify LINE traffic, potentially causing LINE to consume your regular data. If you use a VPN for privacy or accessing region-restricted content, you may need to disable it when using LINE to ensure GigaFree works correctly.
Switching between Wi-Fi and LINEMO's cellular network during active LINE sessions can occasionally confuse the traffic identification system. And rarely, OS or app updates that change how data is packaged and transmitted can temporarily affect whether traffic is properly identified as LINE communication.
Which LINEMO Plans Include LINE GigaFree?
The good news: ALL LINEMO plans include LINE GigaFree as standard at no additional cost. You don't pay extra for this feature—it's built into every plan from the cheapest to the most expensive.
Current Plans (2026)
LINEMO currently offers two main plans with different data tiers and pricing structures. The Best Plan uses a variable pricing model that automatically adjusts based on your usage, while the Best Plan V provides a flat rate with more data and included calling benefits.
Best Plan (Variable/Tiered): The Best Plan charges ¥990 per month when you stay under 3GB of data usage, automatically switching to ¥2,090 per month when you exceed 3GB and use up to 10GB. After exceeding 10GB, your speed throttles to 300Kbps for other apps (LINE remains full speed). If you exceed 15GB total, the throttling intensifies to 128Kbps for non-LINE apps, though LINE continues operating normally. Voice calls cost ¥22 per 30 seconds, and LINE GigaFree is included.
Best Plan V (Flat Rate with Calling): This plan provides 30GB of data for a flat ¥2,970 per month and includes a valuable benefit for voice callers: the first 5 minutes of each domestic call are free. After exhausting the 30GB allowance, speeds throttle to 1Mbps for non-LINE apps. Exceeding 45GB triggers further throttling to 128Kbps, though LINE remains unaffected. Voice calls beyond the 5-minute allowance cost ¥22 per 30 seconds, and LINE GigaFree is included.
Old Plans (Grandfathered): Existing customers may still have older plan structures like the Mini Plan (3GB for ¥990/month) or the Smartphone Plan (20GB with variable pricing). All these legacy plans include LINE GigaFree.
All prices listed are tax-included (税込).
How to Verify LINE GigaFree is Working
After signing up for LINEMO, you'll want to confirm that LINE GigaFree is actually functioning and that your LINE usage isn't secretly consuming your data allowance. LINEMO provides several ways to check this.
My Menu Dashboard Method
The most reliable verification method uses LINEMO's My Menu dashboard. Access the LINEMO official site from your smartphone with Wi-Fi turned off—this allows automatic login through your cellular connection. On the home screen, you'll see your current month's data usage. Tap "データ量をみる" (View Data Amount) and then check "残量／使用量の内訳" (Breakdown of Remaining/Used Amount). Your LINE usage should not appear in your data consumption counter at all.
LINE Official Account Method
For a more convenient ongoing check, add LINEMO's official LINE account as a friend. After linking your LINE account with My Menu through the setup process, you can check your remaining data amount directly from LINE chat—asking the LINEMO bot for your usage without even opening a web browser.
Real-World Test
The ultimate verification is experiential. Use up your monthly data allowance through normal activities like watching YouTube, browsing Instagram, or streaming video. You'll notice these apps become noticeably slower as throttling kicks in. While these apps crawl along, try making a LINE video call. If the video call remains smooth and clear with no buffering or quality degradation, LINE GigaFree is working correctly.
Note that data usage displays are unavailable from 0:00-5:00 JST on the 1st of each month due to system maintenance for monthly resets.
Is LINEMO the Only Carrier with LINE Data-Free?
As of 2026, LINEMO is the only major carrier in Japan offering dedicated LINE data-free service. No other major carrier—including ahamo, povo, Rakuten Mobile, UQ Mobile, or Y!mobile—provides similar LINE-specific data exemptions. Some carriers offer other benefits (Rakuten Mobile has unlimited Rakuten Link calls, Y!mobile has LYP Premium perks), but when it comes to making LINE usage not count against your data allowance, LINEMO stands alone in the market.
| Carrier | LINE Data-Free? | Notes |
|---|---|---|
| LINEMO | ✅ Yes | All LINE messaging, voice/video calls data-free |
| ahamo | ❌ No | Standard data usage |
| povo | ❌ No | Standard data usage |
| Rakuten Mobile | ❌ No | Unlimited Rakuten Link calls, but LINE uses data |
| UQ Mobile | ❌ No | Standard data usage |
| Y!mobile | ❌ No | LYP Premium benefits, but not LINE-specific |
If LINE data-free service is important to you, LINEMO is your only option among major carriers.
Real-World Performance: Does It Actually Work?
The technical specifications look promising on paper, but does LINE GigaFree actually deliver in real-world usage? Based on extensive user reports and testing, the feature performs remarkably well with only minor caveats.
Video Calls: The Standout Performance
LINE video calls remain consistently smooth even after you've completely exhausted your data limit and other apps have throttled to barely-usable speeds. The audio and video quality stay clear and stable, with no noticeable lag or connection interruptions. Users report successfully conducting family video calls, remote work meetings, and even multi-hour conversations with no degradation in quality. This reliability makes the feature genuinely valuable rather than just a marketing gimmick.
Messaging and Media: Instant and Reliable
Text messages deliver instantly, and photos and videos send and receive without any delay even when you're throttled. Large file transfers that would normally consume significant chunks of your data allowance simply don't register against your limit. The feature works consistently without requiring any special configuration after the initial setup—it's truly transparent in operation.
Minor Issues to Be Aware Of
The iOS Private Relay interference is the most common technical hiccup, but it's easily fixed once you know about it. Some users get surprised when location sharing consumes data, but this is by design and documented in LINEMO's terms. Browsing the Sticker Shop also uses data, though sending stickers you've already downloaded remains free. These limitations are reasonable given the technical constraints of identifying different types of LINE traffic.
Who Should Choose LINEMO for LINE GigaFree?
LINE GigaFree makes LINEMO an excellent choice for specific user profiles, while other carriers may serve better for different needs.
Ideal Candidates for LINEMO
If you make frequent LINE voice or video calls, send photos and videos via LINE daily, or use LINE as your primary communication method for staying in touch with Japanese friends and family, LINE GigaFree provides genuine value. Students who video call family back home, participate in group study sessions via LINE, or work with limited data budgets particularly benefit from the peace of mind that communication won't get cut off when data runs out.
Remote workers who conduct LINE meetings with colleagues, communicate with clients via LINE, or simply can't afford communication interruptions find LINEMO's reliability essential. Expats who use LINE for daily life activities—communicating with landlords, making restaurant reservations, or contacting service providers—while also video calling family internationally benefit from cost-effective international communication through LINE's VoIP service.
When to Choose Alternative Carriers
If you rarely use LINE for communication, other carriers may offer better pricing for your usage patterns. Users who prefer WhatsApp, Signal, or other messaging apps won't benefit from LINE GigaFree since those services consume regular data. Heavy international travelers who need data while roaming abroad should consider ahamo's free 91-country roaming instead. And users who want maximum data for streaming, gaming, or other non-LINE activities might find Rakuten Mobile's unlimited data more valuable.
Quick decision guide:
✅ Perfect for:
- Heavy LINE users (frequent calls, daily media sharing)
- Students with limited budgets
- Remote workers using LINE for business
- Expats communicating with Japanese contacts
❌ Skip LINEMO if:
- You rarely use LINE
- You prefer other messaging apps
- You need heavy international roaming
- You want maximum data for non-LINE apps
Pricing Comparison: Is It Worth It?
How does LINEMO stack up against competitors when you factor in LINE GigaFree's value?
Light User Scenario (3GB/month)
For users consuming roughly 3GB per month, LINEMO's Best Plan costs ¥990/month and includes 3GB of regular data plus unlimited LINE. If you're a heavy LINE user, your effective data allowance is much higher since LINE video calls alone could consume 1-2GB on a competing plan. This makes LINEMO the best value for light users who rely on LINE.
Competitors include Rakuten Mobile at ¥1,078 for 0-3GB (slightly more expensive with no LINE GigaFree benefit) and povo at ¥0 base plus ¥990 for 3GB topping (flexible but without LINE benefits).
Moderate User Scenario (10-20GB/month)
LINEMO's Best Plan automatically upgrades to ¥2,090/month when you exceed 3GB, giving you 10GB of regular data plus unlimited LINE. After 10GB you're throttled to 300Kbps for non-LINE apps, but LINE continues at full speed.
Alternative carriers include ahamo at ¥2,970 for 30GB plus 5-minute calls and international roaming (more data and better for travelers) and Rakuten Mobile at ¥2,178 for 3-20GB usage with unlimited data in Rakuten areas.
Heavy User Scenario (30GB+)
For 30GB usage, LINEMO's Best Plan V costs ¥2,970/month and includes 30GB data, 5-minute call allowance, and unlimited LINE.
Comparable options include ahamo at ¥2,970 for 30GB with international roaming (better value if you travel) and Rakuten Mobile at ¥3,278 for unlimited data (better if you consistently exceed 30GB).
Winner for LINE Users: LINEMO wins if LINE communication is your priority. For other use cases, compare carefully based on your specific needs.
How to Sign Up (English Process)
LINEMO offers one of the most English-friendly signup processes among major Japanese carriers, making it accessible for foreigners with limited Japanese language skills.
Requirements for Foreigners
You'll need a Residence Card (在留カード) or Passport for identification. Payment accepts both Japanese credit cards and Japanese bank accounts, giving you more flexibility than some competitors. Standard free email services like Gmail or Yahoo work fine for account registration. Your registered address must match exactly with your ID—including middle names if they appear on your residence card.
Application Process
Visit LINEMO's English site at https://www.linemo.jp/language/ and select your preferred plan (Best Plan or Best Plan V). Choose between a physical SIM card (which ships in 2-3 days) or eSIM for immediate activation—though eSIM is only available for permanent residents or special permanent residents. Upload a photo of your Residence Card (covering the gender field for privacy), enter your payment details, and complete SMS verification to finalize signup.
Important eSIM limitation: Temporary visa holders must use physical SIM cards, as eSIM applications require permanent residency status.
Strengths and Limitations
What LINEMO Does Well
The LINE GigaFree feature itself genuinely works as advertised—unlimited LINE usage for messaging, calls, and video with no data consumption. Perhaps more importantly, LINE maintains full speed even when your data limit triggers throttling on other apps, making it a reliable lifeline for communication. The pricing structure from ¥990 to ¥2,970 is competitive with no hidden fees or surprise charges, and the relatively easy English signup process combined with acceptance of Japanese bank accounts (not just credit cards) makes LINEMO accessible for foreigners. Running on SoftBank's network provides excellent urban coverage, and with no contract you can cancel anytime. Some plans even include LINE Stickers Premium Basic free and offer data rollover benefits.
Where LINEMO Falls Short
The data-free benefit only applies to LINE—if you primarily use WhatsApp, Signal, Telegram, or other messaging apps, you get no benefit. Several LINE features still consume data, including location sharing, Sticker Shop browsing, and LINE LIVE streaming, which can catch users by surprise. eSIM is restricted to permanent residents only, forcing temporary visa holders to use physical SIM cards. English support is limited mostly to online chat rather than phone assistance. International roaming is limited and paid unlike ahamo's generous 91-country free roaming. The requirement to disable iOS Private Relay adds a minor inconvenience for privacy-conscious iPhone users. And while SoftBank's urban network coverage is excellent, rural coverage is less competitive compared to Docomo's network.
Key strengths:
- Unlimited LINE usage (messaging, calls, video)
- Full-speed LINE even when throttled
- Competitive pricing (¥990-¥2,970)
- English signup available
- SoftBank network quality
- No contract commitment
Key limitations:
- Only LINE is data-free (not other messaging apps)
- eSIM requires permanent residency
- Limited international roaming
- Must disable iOS Private Relay
- English support mostly online only
Frequently Asked Questions
Q: Does LINE GigaFree work for international LINE calls? A: Yes! LINE calls to anywhere in the world are data-free as long as you're connected to LINEMO's network in Japan. This makes LINE an excellent tool for free international communication.
Q: What if I use a VPN? A: VPN usage may interfere with LINE GigaFree because the VPN encryption prevents LINEMO from identifying LINE traffic. Traffic identification may fail, causing LINE to consume your regular data. Try disabling your VPN when using LINE if possible.
Q: Can I check if LINE GigaFree is active before signing up? A: No, but all LINEMO plans include LINE GigaFree automatically at no extra charge. The feature activates immediately when your service starts—there's no separate enrollment or configuration needed.
Q: Does LINE GigaFree work when roaming internationally? A: No. LINE GigaFree only functions when you're connected to LINEMO's network in Japan. When you're roaming internationally, LINE usage consumes your standard roaming data allowance.
Q: What happens to LINE when I exceed my monthly data limit? A: LINE continues operating at full speed thanks to GigaFree, while other apps experience throttling to 300Kbps-1Mbps depending on your plan and how much data you've consumed.
Final Verdict: Is LINE GigaFree Worth It?
YES, if LINE is your primary communication tool.
LINE GigaFree is not a gimmick—it genuinely works and provides real value for LINE users. The ability to video call family, send photos without worry, and stay connected even when your data runs out is a game-changer for international students, expats with Japanese contacts, remote workers using LINE for meetings, and anyone who relies on LINE for daily communication in Japan.
The feature performs consistently and reliably in real-world usage. Video calls stay smooth when everything else throttles, messaging remains instant, and the transparent operation means you don't need to think about it—it just works.
For users who rarely use LINE or who prefer other messaging platforms, LINEMO's main selling point becomes irrelevant, and other carriers may offer better value for your specific usage patterns.
