I purchased A Digi Transport WR11 XT for an application to allow access from a machine supplier to my machine for to allow them to diagnose problems with the machines. They need to have two way communication to access the system and send code and to receive machine status from my side.
I purchased a Verizon sim Card DVM0007e. Digi tels me this is the wrong card and I need another type of card. See the note from Digi below:
If you have a need for someone to remotely access this WR11 then I’m afraid that would not be possible because of this SIM card and APN. The “vzwinternet” APN (and any SIM that uses this APN, which is related to the Verizon data plan) limits you (the WR11 in this case) to only be able to get OUT TO the Internet, not vice versa. It’s a basic type of plan. You have a private NAT’d (unreachable from the Internet) mobile IP address with this SIM card. If you need a Public (as opposed to Private) mobile IP address then you would need a different “higher tier” SIM and data plan. Does this make sense?
