All commands that are sent/processed during the initialization of the gateways are more or less setup for retries. Sometimes, a reset command is in the AT handlers, so the initialization commands run immediately after a reset. After a reset, a modem may be in a "weird" state, at least until it registers itself with the gsm network. That's why most commends there are setup with retries (CPIN, CREG, etc).
The CNMI (theoretically) should NOT fail. It has nothing to do with the network - its a pure ability (which the modem either has it or not) that describes how the modem responds to inbound messages. The increased retries that you've implemented is a good way to deal with this. A better way would be to try with another modem...
