Who NexSMS Is For
NexSMS is worth considering if you need:
- OpenAI, ChatGPT or Codex SMS verification.
- WhatsApp SMS or voice verification.
- Claude, Telegram, Google, Amazon, eBay, Instagram, Facebook or TikTok codes.
- A higher-quality option than shared public numbers.
- A long-term phone number that can keep receiving SMS during the rental period.

Premium Numbers for OpenAI, Codex and WhatsApp
The premium number pool is the most important part of NexSMS. The dashboard shows different project pools, such as ChatGPT / OpenAI, WhatsApp, Google, Amazon and Claude, with success rates and available quantities.
According to the platform description, premium numbers are physical SIM cards that have been pre-screened to improve success rate and delivery speed. If a number cannot receive the code, users may unsubscribe and have the cost returned to account balance, subject to the rules shown on the order page.
For OpenAI, Codex, Claude, TikTok and WhatsApp, this is usually a better approach than repeatedly trying random public numbers.
Real SIM Rental for Long-Term Accounts
NexSMS also offers exclusive real SIM rental. This is useful when you want to keep one phone number for a longer time instead of using a one-time activation.
Real SIM rental includes:
- Monthly billing.
- Automatic assignment after payment.
- Continuous SMS receiving during the rental period.
- Self-service renewal before expiration.
- Better fit for WhatsApp, Telegram, OpenAI and accounts that may require future verification.
Renew before expiration. Once a number is released, future login or recovery codes may no longer be available to you.
Number Types and Validity
NexSMS supports US virtual numbers, Canada numbers, Hong Kong numbers, US real SIM numbers and UK numbers. US real SIM cards can have a maximum validity of 30 days, while other number types can have a maximum validity of 80 days. The validity period starts when the card is added to the system, not necessarily when you purchase it.
Important notes:
- Purchased numbers usually receive SMS only for the selected project.
- A first-use card means a new unused number, but some new-operator numbers may include recycled numbers after a 3 to 6 month cooling period.
- Rebooted cards and renewal cards usually do not support after-sales service.
- Premium selected numbers are normally non-refundable and non-exchangeable after purchase.
Voice Verification
Selected new US operator cards support voice verification calls for all projects. The system can answer calls automatically and convert the verification code into text. It supports last-six-digit voice codes and interactive keypress voice flows.
The voice service is free for supported US cards, but it is only available on US cards. Always check the live platform notice before purchase.
How to Use NexSMS
- Open the NexSMS registration page and create an account.
- Use free public numbers for simple testing.
- For OpenAI, Codex, WhatsApp or Claude, go to premium numbers.
- Select a country first, then filter by project name.
- Review success rate, stock and number notes before buying.
- Enter the number on the target platform and wait for SMS or voice code.
- For long-term accounts, use real SIM rental and renew before expiration.
Buying Advice
Use free SMS receiving only for low-risk temporary tests. For OpenAI SMS verification, ChatGPT phone verification, Codex verification, WhatsApp verification and Claude verification, choose premium real SIM numbers when possible. For accounts that may need future login or recovery codes, monthly real SIM rental is more practical than one-time numbers.
