Notes:

AT+CFUN=1 used to set radio function and power mode.

Instant Peak Tx: The peak current during a GSM850 transmission burst period or HSDPA connection. This
current is handled by bulk capacitance in a design.

Measured Current: The continuous current during a Transmit with the radio transmitter at specified power.

Inrush Current: The input current during power up, or a reset.

Registered Power: Registered to tower. Receive active for SMS. No data is sent.
