Yes I've used GT-540-3GWA to get Modbus data over the cellular network.  I connected my modbus devices over the RS-485 port.  I configured it with the software utility that came with it and was able to get Modbus data from a PLC and I/O.

GT-540-3GWA$699.00        Cellular Wireless Intelligent GPRS Data Server with 6 Digital Inputs, 2 Digital Outputs and 1 Analog Input. Supports 2G Quad-band 850/900/1800/1900 MHz Frequencies and 3G 850/900/1900/2100 MHz. Provides Wireless Access to Modbus RTU devices. Supports operating temperatures from -25°C ~ +75°C (-13°F ~ +167°F)
