Last character of SMS missing

[Edward-2]

• Arduino board: Nano, 328P, Multiple tested
• Arduino IDE version: 2.3.2
• This same test code(Adafruit examples and Arduino Nanos) work perfect with SIM800L, SimCom A7670G module, but not with a SimCom SIM7670G module.
  When receiving any length test SMS message, the last character disappears, regardless of message length, Like send: "Test edaboard" received: "Test edaboar".
  The SIM7670Gs tested receive the full SMS message when tested with direct USB connection (Putty) and AT Command Tester.
