Quick answer: When Yahoo Mail signup needs phone verification and your local number fails or is rejected, rent an overseas real-SIM number on SimSmsBox and complete the SMS step. Keep the country nearby, prefer
physicalSIMs, and skip free public pools.

Here’s the receive-SMS path to get Yahoo Mail phone verification done.
Why it fails
- Virtual / VOIP numbers rejected by Yahoo;
- Free-pool numbers reused and pre-flagged;
- Local carrier blocks international SMS;
- Too many number swaps in a short window trip rate limits.
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 yahoo (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":"yahoo","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"
# -> { "status": "received", "latestCode": "482913" }
