Before purchasing any GSM controller, you should first make sure that it suits your intended application. Note that our GSM controllers are NOT REAL-TIME controllers and are NOT SAFETY CRITICAL controllers. Our GSM controllers are not authorized for use as safety critical components in health and life support devices or control systems. (Life-support devices or systems are devices or systems intended for surgical implantation into body or to sustain life, and whose failure to perform,  can be reasonably expected to result in significant injury). No complex software or hardware system is perfect. Bugs are always present in a system of any size. In order to prevent danger to life or property, it is the responsibility of the system designer to incorporate redundant protective mechanisms appropriate to the risk involved.

The time taken for a SMS message to be sent by the controller can vary from anywhere between a few seconds to tens of seconds, depending on network load. This means that rapidly changing inputs will go undetected. Effectively, you will be left not knowing what the real state of the input port is, despite having received a host of state change messages. In other words, the input should only be used to sense signals that change infrequently over time. Alarm signals are a typical example, as they are expected to change only during exceptional conditions.

A second pitfall has to do with SMS costs. You must use a prepaid SIM CARD account. A malfunctioning system could cost you a fortune on an open-ended plan. In theory, if the controller were to send messages as fast as the network would allow, more than 17000 messages could be sent in one day alone. On a $10 plan, this would be a disaster. We therefore strongly recommend that a PREPAID SIM CARD be setup for the controller. This ensures that if something goes wrong, you already know how much it is going to cost you. The controller could not send any message once the prepaid account is used in full.
