Notes
•
will deactivate any PDP context.
ATH
•
If the MT is in dedicated mode, the write command returns "+CME ERROR: operation temporary not allowed".
•
A maximum of 2 contexts can be activated at the same time, no matter on which interface. Trying to activate
more than 2 contexts will cause "+CME ERROR: operation temporary not allowed". Note that, depending on
the provider, the number of activated contexts may be further restricted. In such cases "+CME ERROR:
unspecified GPRS error" will be returned and
Remember that contexts may be activated implicitly by using the
commands without specifying a <cid>.
•
If an activated context will be deactivated without using the command AT+CGACT, then the result code "NO
CARRIER" will be issued to indicate the context deactivation. This happens for example if the context deac-
tivation is forced by the network or if deactivation results from a network deregistration with AT+COPS=2.
