Perplexity usually lets you sign up with email or Google, but a risk check, phone binding, or certain regions can trigger an SMS verification step. If your own number can’t receive the code — or you want to verify with an overseas number — you can finish with a number that receives SMS. Follow the steps below.

Why the phone check appears
- Abuse prevention: a phone number confirms a real person and limits bulk signups.
- Virtual / VOIP numbers get rejected: prefer a real SIM, see Real SIM vs virtual numbers.
- Number country doesn’t match your IP: a mismatch can trigger risk control, so pick a country close to your network.
Verify Perplexity with SimSmsBox
Step 1: Pick a country close to your network
Keep the number’s country near your network environment; a real SIM clears far more reliably than a virtual number.
Step 2: Order a number
curl -X POST https://api.simsmsbox.com/api/sms/orders/purchase -H "X-API-Key: psk_xxx" -H "Content-Type: application/json" -d '{"service":"perplexity","country":"US","cardKind":"physical","rentDays":30}'
# -> { "orderId": 52, "phone": "+1xxxxxxxxxx", ... }
Step 3: Enter the number and request the code
Enter this number in Perplexity’s verification field and request the SMS code.
Step 4: Poll to retrieve the code
curl https://api.simsmsbox.com/api/sms/orders/52 -H "X-API-Key: psk_xxx"
# -> { "status": "received", "latestCode": "593028" }
For cadence, see Automated ordering and polling — query every few seconds after ordering, don’t hammer it.
Step 5: Enter the code to finish
Put latestCode back into Perplexity to complete verification.
