• If CSMS mode is switched from Phase 2+ to Phase 2 and one or more AT+CNMI Parameter are Phase 2+
specific a '+CMS ERROR: unknown error' will appear. It is recommended to switch the AT+CNMI Parameters
to Phase 2 specific values before entering Phase 2. 
• Phase 2+ (<service>=1) must be set before the following features can be used: 
- Configuring procedures for indicating received short messages with the AT+CNMI parameters <mt>=2 or
<mt>=3 and <ds>=1. 
- Acknowledging incoming short messages with AT+CNMA. 
- Receiving Status Reports and acknowledging them with AT+CNMA.
