In May, the Federal Communications Commission announced that it wanted to see its text-to-911 service rolled out across all network carriers in the United States. Now the process has moved a stage further: On Friday, the body voted in favor of rules that will compel U.S. carriers and some app developers to implement the system by the end of 2014. The option to send an SMS for help is already available on the bigger networks, but this ruling means that smaller firms will also be obliged to co-operate, ensuring the service is available across the country. Just make sure you don’t use it to complain about a Facebook outage.
