Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.

1. AT Commands Description
This manual presents detailed information about the AT command set used with the AirPrime WS
Series of Intelligent Embedded Modules including WISMO218 and WISMO228.
Note: There is no SIM card auto-detect mechanism for the AirPrime WS Series of embedded modules. After
the SIM card has been changed, the embedded module has to be restarted in order to detect the new
SIM card. If the SIM card is not detected by the embedded module, most of the AT Commands will
return ERROR.

Discard indication and reject new received message unsolicited result codes when TATE link is reserved (e.g. in on-line data mode). Otherwise forward them directly to the
TE. Not supported for CBM messages.
2
Buffer unsolicited result codes in the TA when TA-TE link is reserved (e.g. in on-line
data mode) and flush them to the TE after reservation. Otherwise forward them directly
to the TE.
3
Forward unsolicited result codes to the TE by using the following specific inband
method:
While TA-TE link is reserved (meaning the TE is in online data mode by CSD or GPRS
call), unsolicited result codes are replaced by a break (100ms) and stored in a buffer.
The unsolicited result codes buffer is flushed to the TE after reservation (after +++ is
entered). If however the TE is not in online data mode, it forwards them directly to the
TE.
<mt>
Description
0 (default)

Command operates similarly as defined for the text mode
1
Send RP-ACK (or buffered result code received correctly)
2
Send RP-ERROR
Acknowledgement TPDU not supported
Clarification
TA result code buffer is in volatile memory. Messages may get lost if the power of ME/TA is switched
off before codes are sent to TE. Thus, it is not recommended to use direct message routing (<mt>=2
or 3, <bm>=2 or 3, or <ds>=1) with <mode> value 0 or 2.
When +CSMS <service> is set to 0, all received SMS are automatically stored in SIM before +CMT or
+CMTI URC is sent to TE whatever <mt> value.
When +CSMS <service> is set to 1, depending of it class, SMS has to be acknowledged to network
thanks to +CNMA commands. Depending of <mode>, <mt> and channel status (available or
reserved) URC cannot or should not be sent to TE. In these cases SMS can be automatically
acknowledged or rejected without waiting +CNMA command.
+CNMI parameters are automatically saved in non-volatile memory.
2.3.2. +CNMA New Message Acknowledgement to ME/TA
Parameters
Clarification
This command is allowed only if +CSMS <service> is set to 1 and is used to acknowledge SMS
received from network.

Routing of SMS-DELIVER and SMS-STATUS-REPORT to ME/TA depends on both +CSMS

In PDU, acknowledgement TPDU is not supported.
The following table summarizes the SMS-DELIVER notification modes according to these parameters:
When SMS Mode = 0: SMS acknowledgement and storage are managed internally by MS whatever
their class (if needed they will be stored in SIM).
When SMS-DELIVER Mode = 1: SMS with no message class, class 0, class 1, class 3 are sent to
ME/TA for acknowledgement
them. SMS class 2 & message waiting indication group (Store or Discard) are managed internally by
MS (if needed they will be stored in SIM, no +CNMA expected).
When SMS-DELIVER Mode = 2: SMS class 3 are sent to ME/TA for acknowledgement (+CNMA
class 0, class 1, class 2 & message in waiting group are managed internally by MS (if needed they will
be stored in SIM, no +CNMA expected).
Following table summarizes the STATUS-REPORT (SR) notification modes according to +CSMS and
<ds> parameters:
When STATUS-REPORT Mode = 0: MS manages SR internally.
When STATUS-REPORT Mode = 1: SR are sent to ME/TA for acknowledgement and storage.

In PDU mode: <length> must indicate the number of octets coded in the TP layer data unit to be given
(i.e. SMSC address octets are excluded).
The TA sends a four character sequence <CR><LF><greater_than><space> (IRA 13, 10, 62, 32)
after command line is terminated with <CR>; after that text can be entered or PDU can be given from
TE to ME/TA.
The DCD signal shall be in ON state while text or PDU is entered.
The echoing of entered characters back from the TA is controlled by V.25ter echo command E.
In text mode, the entered text should be formatted as follows:
if <dcs> (set with +CSMP) indicates that GSM 7 bit default alphabet is used and <fo>
indicates that TP-User-Data-Header-Indication is not set: ME/TA converts the entered text
into the GSM 7 bit default alphabet according to rules of Annex A; backspace can be used to
delete last character and carriage returns can be used (previously mentioned four character
sequence shall be sent to the TE after every carriage return entered by the user);
if <dcs> indicates that 8-bit or UCS2 data coding scheme is used or <fo> indicates that TP-
User-Data-Header-Indication is set: the entered text should consist of two IRA character long
In PDU mode:

hexadecimal numbers which ME/TA converts into 8-bit octet (e.g. two characters 2A (IRA 50
and 65) will be converted to an octet with integer value 42).
The PDU shall be hexadecimal format (similarly as specified for <pdu>) and given in one line;
ME/TA converts this coding into the actual octets of PDU. When the length octet of the SMSC

Parameters
2.5.2. +CMT Received SMS indication
Parameters
For all other parameters, refer to 27.005 §3.1 Parameter Definitions.
Clarification
When +CSMS <service> is set to 0, all received SMS are automatically stored in SIM before +CMT is
sent to TE.
When +CSMS <service> is set to 1, depending of it class, SMS has to be acknowledged to network
thanks to +CNMA commands. Depending of <mode>, <mt> of CNMI or channel status (available or
reserved) URC cannot or should not be sent to TE. In these cases SMS can be automatically
acknowledged or rejected without waiting +CNMA command.
When a +CMT URC is sent to TE for a SMS that has NOT been acknowledged by TA, a timer is
started. If timer expires (15sec) before +CNMA command is received, SMS is rejected.
When a +CMT URC is sent to TE for a SMS that has already been acknowledged by TA a timer is
started. If timer expires (15sec) before +CNMA command is received, SMS is automatically saved in
SIM (this is to not to lost an already acknowledged SMS for which +CNMA has not been received in
case of switch off). If CNMA is received before timer expiration OK is returned, else ERROR is
returned (TE knows that SMS has been stored in SIM).

In case of TP-DCS method, for message waiting indication group (store message), +CMTI is sent.
For message waiting indication group (discard message) +CMT URC is sent but no +CNMA

Parameters
For all other parameters, refer to 27.005 §3.1 Parameter Definitions.
Clarification
When +CSMS <service> is set to 0, all received SR are automatically acknowledged before +CDS is
sent to TE.
When +CSMS <service> is set to 1, SR has to be acknowledged to network thanks to +CNMA
commands. Depending of <mode>, <mt> and channel status (available or reserved) URC cannot or
should not be sent to TE. In these cases SR can be automatically acknowledged or rejected without
waiting +CNMA command.

Clarification
When TE sends an USSD to the network, the OK result code is sent before the response of the
network. When network answers, the response will be sent as an URC (as if it was a network initiated
operation, in case of error +CUSD: 4 will be sent).
This allows the link not to be blocked for a long time (the network can take a long time to answer a
USSD request initiated by the TE).
The USSD session can be aborted using command AT+CUSD=2.

3.6.2. +CFUN Set phone functionality
Parameters
Clarification
AT+CFUN=1,1 has no effect on radio on/off, it leaves it as the same state it was before reset.
AT+CFUN=1,0 requests a radio on and memorize in non volatile memory <fun> level.
AT+CFUN=4,0 requests a radio off and memorize in non-volatile memory <fun> level.
At next switch on, ME will start with the <fun> level of the last +CFUN (i.e radio on or off). This allows
TE to have control on radio on/off.
+CFUN parameter is automatically saved into non-volatile memory.
The <fun> parameter is restored to default value by AT&F. Note that the module has to be restarted to
restore the default value. For example, if the current value of +CFUN=4 and AT&F is used to restore it
to default value, although +CFUN: 1 is displayed, the radio will not be turned ON until the module is
restarted.

Clarification
For <cid> 1,2 and 3, PDP context definition is stored in EEPROM i.e parameters provided in
+CGDCONT for PDP context definition and PDP context status (defined/undefined) are stored in nonvolatile memory (If a PDP has been defined with +CGDCONT, after a switch off / switch on,
AT+CGDCONT? will list the PDP has defined).
<cid> 3 is locked. This means that TE is not allowed to modify definition and parameters of <cid>=3
with +CGDCONT set command. This gives a default PDP context with parameters that TE cannot
change.
<cid> 3 is also the default <cid>: if +CGDCONT with <cid> omitted is received, <cid> 3 will be used.
+CGDCONT parameters are automatically saved into non-volatile memory.

Parameters
Clarification
This command is used to tests PDPs with network simulators. Successful activation of PDP on real
network is not guaranteed, as it depends on whether the real network supports GPRS/EDGE service.
Refer to section 3.10.7 +CGDATA Enter data state for more information.
Examples:
To activate all defined contexts:
AT+CGACT=1
To deactivate all defined contexts:
AT+CGACT=0
To activate context 1:
AT+CGACT=,1
or
AT+CGACT=1,1
To activate context 2:
AT+CGACT=,2
or
AT=CGACT=1,2
Note: Entering AT+CGACT= (no specified parameters) returns OK without activating or deactivating the
PDP context.

3.10.6. +CGCMOD PDP Context Modify
Parameters
Clarification
Recommendation specifies that after the command has completed, the MT returns to online data state
From a Sierra Wireless point of view, +CGCMOD behaviour is more similar to +CGACT command,
hence the implementation choice is not to switch link to online data mode after PDP context
modification.
TE will have to send +++ escape sequence to switch channel to online command if +CGCMOD
cannot be performed from another AT channel. TE will have to use O command, if required, to switch
channel to online data mode.
3.10.7. +CGDATA Enter data state
Parameters
Clarification
If no parameters are provided (i.e +CGDATA<CR>), the last <cid> activated with +CGACT or the
default <cid> is used.

This command is used for PDP tests on network emulators. On real network functioning of +CGACT
and then +CGDATA for data transfer is not guaranteed.
+CGDATA implementation does not perform PS attach or PDP context activation. The PDP identified
by <cid>, when provided, in +CGDATA must have been activated previously thanks to +CGACT
command.
+CGDATA only switches channel to online data mode and open PPP server in a proprietary mode
as a relay).
For IP over PPP services, ATD*98 or ATD*99 commands must be used: when activating a PDP
context, PCO (protocol configuration option) has to be provided to network. PCO can be provided to
network only if a PPP negotiation (LCP/NCP negotiation) has been initiated between mobile and TE
before PDP activation (refer to TS 27.060 §9.1). This negotiation is possible only if AT channel is
switched to online data mode before PDP context activation. Hence, the PDP identified with <cid> in
+CGDATA should not have been activated by +CGACT not possible in the current implementation
(+CGDATA does not behaves as ATD*9x when <cid> is not activated).
