SimSmsBox Quick answer: For Naver (Korea’s biggest portal), a SimSmsBox Korean real-SIM number can complete the phone SMS step; but some Naver services also require Korean local identity verification (real-name / i-PIN) — a platform can’t do that, so whether a service unlocks depends on the service. Real SIM + a Korean number improves your odds.
Honest heads-up: Naver is strict on overseas signups. Receive-SMS only covers the phone SMS step; some services (payments, real-name zones) also require Korean phone real-name or i-PIN identity verification, which a platform can’t do. Basic signup/login usually works, but full real-name services aren’t guaranteed.
Here’s the receive-SMS path to get Naver phone verification done.
Why it fails
- Virtual / VOIP numbers almost always blocked;
- Free-pool numbers mass-registered and pre-flagged;
- Non-Korean number + foreign IP tightens risk control;
- SMS passes but you get stuck at local identity verification.
Troubleshoot: SMS code not received.

New to the flow? How to use an SMS platform.
1. Reach the phone step first
Finish email / profile fields before buying a number so you don’t waste the rental window.
2. Pick country + real SIM
Keep the country close to your network; prefer physical — see real SIM vs virtual.
3. Purchase
Use service naver (check the shop list):
curl -X POST https://api.simsmsbox.com/api/sms/orders/purchase \
-H "X-API-Key: psk_xxx" -H "Content-Type: application/json" \
-d '{"service":"naver","country":"US","cardKind":"physical","rentDays":30}'4. Request SMS (not a call)
Enter the number and send via SMS, not voice.
5. Poll the code
curl https://api.simsmsbox.com/api/sms/orders/91 -H "X-API-Key: psk_xxx"

FAQ
Q: Can I register with receive-SMS alone? A basic account usually works; real-name services still need Korean local identity verification.
Q: Which country’s number? Prefer a Korean real SIM and pair it with a Korean-region IP.
Q: Will it get banned after signup? New accounts are high-risk early; use it normally and avoid frequent device switching.
Takeaway
Stuck on Naver phone verification? Use a clean overseas real-SIM SMS number — nearby country, SMS only, poll the code. Platform comparison: SMS platform vs 5sim.
