Unfortunately, none of the websites listed previously provide SMS alerts for preclinical result declarations or FDA approvals. However, some websites offer email alerts, which you can then forward to your phone if you don't have access to a computer or mobile device.
If you're looking for SMS alerts, you might consider using a dedicated service like Textedly or Twilio, which allow you to set up SMS alerts for specific keywords or topics. You can then use the websites I mentioned earlier to trigger alerts through this service.
Another option is to contact the websites directly to inquire about potential SMS alert options. Some websites may be able to accommodate your request, especially if you're a registered user or have a significant interest in their content.
Keep in mind that setting up SMS alerts may require additional steps and might not be as widely available as email alerts. If SMS alerts aren't essential, you can still use the websites' email alert systems, which are often easy to set up and provide timely notifications.
