If you are looking for a security device to work via a sim card then a site survey is something you should consider, at Entrytrch we can come to your site or the location you are thinking of using a 3/4G device and we can tell you the best network to use, the direction of the transmitter and suggest the best location for the antenna if the device uses an external one.  Once we have completed our 3/4G signal we will send you a file via email showing all the network data.
