During Katrina, and recently the Nevada earthquake, traditional cellular voice service was overwhelmed due to a combination of damaged infrastructure and system overloads. In many cases, however, it was noted that Short Messaging System (SMS or “text”) would often function when voice circuits would not.
It’s also possible to send these SMS messages via e-mail in most cases, using SMS Gateways. If you are deploying ham radio EmComm team members into an affected area, you should test their cell phones for this capability before they leave. It’s also important to limit the message length, since most carriers restrict SMS messages to 160 characters. Below is a list of the major carriers in North America that offer SMS gateway services. Others can usually be found using search engines.
An SMS gateway provides an easy way for you to communicate with deployed ham radio EmComm team members, family members, or anyone whose cell phone number and carrier you’re sure of. In many cases, we were able to help people outside the affected area reach their loved ones more quickly using these gateways.
Also, before deploying in approach of Katrina and Rita, we purchased inexpensive pre-paid cell phones at Wal-Mart for two or three of the other major carriers (we carry T-Mobile phones). These included Verizon, Cingular (AT&T), and Spring. Even in some of the worst areas impacted by the storms, we were usually able to communicate on at least one of the phones we had with us. This adds an important degree of team safety.
