it is possible Tmobile disable the SIM due to large amount of SMS messages being send and receive on the account.

we currently do not have any MTCDP models that have the voice port available.

Telit HE910-D does not support voice.

how many SMS messages are you sending across the other network such as AT&T, Verizon or Sprint ??

it is known that the carrier will block SMS from other carrier if they detect a lot of SMS coming from the same number.

the coin battery is only for the realtime clock

[Kevin]

are you looking at Modbus communication for Point to Point or Point to MultiPoint ?

If your PLC supports RS232, you can use the RS232 port on the CDP to communicate with PLC and then implement the Modbus protocol in Linux. There are many open source Modbus protocol library available on the internet.

If your PLC supports only RS485, then you might need to use an external adapter that can convert RS232 to RS485.
