13.10.4 Notes
• The DTE application should set a reasonable timer (10 s) when receiving the +CGREG: 3 URC, since this
might be due to the fact that the LTE registration was rejected (SIM not enabled for LTE RAT, wrong APN
during the initial default bearer set-up in the EPS attach procedure and other temporary reject causes).

13.11.1 Description
This command H (On-hook) deactivates a pending PDP context with PPP L2 protocol in online command mode.
The MT responds with OK. See
In GPRS online command mode, entered by typing the escape sequence "+++" or "~+++" (see
), the ATH command is needed to terminate the connection. Alternatively, in data transfer mode,
DTE originated DTR toggling or PPP disconnection may be used.

13.12.1 Description
Sets the MT to operate according to the specified mode of operation for EPS, see 3GPP TS 24.301 [
]. If the
requested operation mode is not supported, an error result code is returned.
u-blox cellular modules are certified according to all the capabilities and options stated in the Protocol
Implementation Conformance Statement document (PICS) of the module. The PICS, according to 3GPP
TS 51.010-2 [
], 3GPP TS 34.121-2 [
], 3GPP TS 36.521-2 [
] and 3GPP TS 36.523-2 [
], is a statement
of the implemented and supported capabilities and options of a device. If the user changes the command
settings during the certification process, the PICS of the application device integrating a u-blox cellular
module must be changed accordingly.
