  • Receive LINE verification SMS to a shared team inbox
  • Real-SIM US number — not on LINE's VoIP blocklist
  • Long-term rental: same number for setup, re-login, and security checks

Why LINE blocks VoIP numbers

LINE enforces one of the most explicitly documented VoIP blocks of any messaging platform. LINE's Help Center states verbatim: “you will not be able to use virtual phone numbers or phone numbers that start with 050.” The platform requires numbers offered by a mobile service provider — meaning real, physical SIM cards only. This block is two-layered, which is why users often find themselves stuck even after switching number providers.

  • "Sorry, text message verification isn't available in your country" — displayed when region or carrier type is rejected
  • "The phone numbers that can and can't be used for verification should be checked" — LINE's generic error, typically appears when a VoIP number is entered
  • Account access suspended after repeated failed verification attempts (temporary lockout)
  • The "Call Me Instead" voice option also fails — LINE checks carrier signatures through both SMS and voice verification paths
  • As of LINE v13.11.0+, phone registration may be restricted to users in Hong Kong, Japan, Korea, Taiwan, and Thailand

Note: LINE updates their security frequently. We can't guarantee acceptance. See the limitations section for details on LINE's regional restrictions before purchasing.

Bypass LINE verification blocks with Real SIMs

JoltSMS provides physical SIMs on US carrier networks (T-Mobile/AT&T) — not virtual, not cloud-based, not caught by LINE's carrier-signature check. LINE's Help Center is explicit: virtual phone numbers are banned. Real-SIM numbers carry the carrier signatures LINE's verification system looks for.

  • Physical SIM cards on US carrier networks (T-Mobile/AT&T) — not VoIP or cloud telephony
  • Dedicated to you alone — no number sharing, no contamination from previous users during your rental
  • Long-term availability month-to-month — the same number LINE will require for every future re-verification event
  • Team inbox — share SMS access across your team via Slack, Discord, Email, and Webhook notifications

Who uses JoltSMS for LINE?

Expats and Former Residents

US-based users who previously lived in Japan, Korea, or Taiwan and built years of contacts on LINE. When they changed to a US number, their account lost its verified phone anchor. A JoltSMS real-SIM number restores access and provides a stable, long-term number for future verification events — protecting the entire social and professional graph they built abroad.

Asia-Focused Marketing Agencies

US-based agencies running LINE Official Account campaigns for brands targeting Japan, Thailand, or Taiwan. LINE account management requires a verified phone number, and losing access mid-campaign means lost client revenue. A dedicated JoltSMS number anchors the account for the duration of the engagement and survives staff turnover.

Community and Fan Group Members

Users participating in LINE groups for gaming communities, fan circles, professional associations, and regional communities. These users need LINE access without linking a personal phone number — JoltSMS provides an inbound-only, private dedicated number for this purpose.

What to know before you buy

Not affiliated with LINE or LY Corporation. JoltSMS provides phone numbers for legitimate account verification.

Best practices:

  • Provision your number before you start the verification flow — have it ready before LINE prompts you
  • Keep your subscription active — LINE requires the same registered number for every future login and device change
  • Do not let your subscription lapse if your LINE account is business-critical
  • If you manage multiple LINE Official Accounts, provision a separate JoltSMS number for each
  • Note: LINE v13.11.0+ may restrict new account phone registration to Hong Kong, Japan, Korea, Taiwan, and Thailand. JoltSMS is most clearly viable for re-verifying existing accounts, LINE Official Account management, and older LINE versions
  • Also works for WeChat verification for expats navigating Asian messaging platforms

LINE verification FAQ

LINE explicitly bans virtual phone numbers and checks carrier signatures during verification. JoltSMS provides real-SIM numbers on US mobile carrier networks — not VoIP, not cloud-based. These numbers carry the carrier signatures that LINE's verification check looks for. That said, LINE's geographic restriction policy affects some use cases. We recommend reading the limitations section carefully. We can't guarantee acceptance on any specific platform — LINE ultimately decides which numbers to accept.
