I have two S7-1200 PLCs withCP1242-7, I want them to communicate in "GPRS direct mode". Did everything as discribed in Set31 example -Variant “M2M with S7-1200 directly via GPRS”. When I start both PLCs, TC_CON block executes for a very long period of time and eventually returns with error and status: "80E8 Remote partner cannot be reached. Check the connection parameters. In the "GPRS direct" mode, the message is output if the partner is reachable but does not react to the connection request." What am I doing wrong? What parameters should I check? (I've attached my TIA V12 project to this message).

Setting up a private APN solved the problem! FYI: my GSM operator is MTS (Russia).
