Common Issues & Solutions
"No US numbers available"
Sometimes Twilio runs out of US numbers. Try again in a few hours, or contact Twilio support to request a number manually.
"Payment method declined"
Make sure your credit/debit card supports international payments. US banks sometimes block international transactions by default: call your bank to enable them.
"Test connection failed"
Double-check that you copied the Account SID and Auth Token correctly. Make sure there are no extra spaces. Also verify that your phone number includes the country code (+1).
"Calls not going through"
Check that your Twilio account has sufficient balance. Also make sure the phone number you purchased has "Voice" capability enabled.
