SimSmsBox Quick answer: For WeChat signup, a SimSmsBox overseas real-SIM number can complete the SMS verification step; but a new WeChat account often still needs an existing user to scan a QR for “friend assist” — a platform can’t do that step, so success depends on WeChat’s risk control. Real SIM + a nearby country improves your odds.
Honest heads-up: WeChat is the hardest in this batch. Receive-SMS only covers the “phone SMS verification” step; a brand-new account will most likely require an existing WeChat user (account 6+ months old, recently active) to scan a QR for assist verification. Without such a helper, even a received SMS may not get you fully activated. Receive-SMS solves the SMS step, not the whole flow.
Here’s the receive-SMS path to get WeChat phone verification done.
Why it fails
- Virtual / VOIP numbers almost always blocked;
- Free-pool numbers mass-registered and pre-flagged;
- New number + new device + foreign IP tightens risk control;
- SMS passes but you get stuck at “friend assist” (needs an existing user to scan).
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 wechat (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":"wechat","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? Not always. The SMS passes, but if “friend assist” triggers you need an existing user to scan a QR — a platform can’t do that.
Q: Which country’s number is best? Stay close to your usual region and IP; cross-region numbers trip risk control more easily.
Q: Will the account get banned after signup? New accounts are high-risk early on. Use it normally and avoid mass-adding contacts or sending links right away to lower ban risk.
Takeaway
Stuck on WeChat phone verification? Use a clean overseas real-SIM SMS number — nearby country, SMS only, poll the code. Platform comparison: SMS platform vs 5sim.
