+    ## Identifying the device from the access token
+
+    This API requires the API consumer to identify a device as the subject of the API as follows:
+    - When the API is invoked using a two-legged access token, the subject will be identified from the optional `device` object, which therefore MUST be provided.
+
+    - When a three-legged access token is used however, this optional identifier MUST NOT be provided, as the subject will be uniquely identified from the access token.
+
+    This approach simplifies API usage for API consumers using a three-legged access token to invoke the API by relying on the information that is associated with the access token and was identified during the authentication process.
+
+    ### Error handling:
+    - If the subject cannot be identified from the access token and the optional `device` object is not included in the request, then the server will return an error with the `422 MISSING_IDENTIFIER` error code.
+
+    - If the subject can be identified from the access token and the optional `device` object is also included in the request, then the server will return an error with the `422 UNNECESSARY_IDENTIFIER` error code. This will be the case even if the same device is identified by these two methods, as the server is unable to make this comparison.
+
+    ## Multi-SIM scenario handling
+
+    In multi-SIM scenarios where more than one mobile device is associated with a phone number (e.g. a smartphone with an associated smartwatch), it might not be possible to uniquely identify from that phone number the device for which connected network type notifications should be generated. If the phone number is used as the device identifier when creating a subscription in a multi-SIM scenario, the API may:
+    - respond with an error, or
+    - generate network type change notifications for the multi-SIM group as a whole, or
+    - generate network type change notifications for a single device in the multi-SIM group, which may not be the intended device.
 
-    (FAQs will be added in a later version of the documentation)
+    Possible solutions in such a scenario include:
+    - Using the authorisation code flow to obtain an access token, which will automatically identify the intended device
+    - Identifying the intended device from a unique identifier for that device, such as its source IP address and port
+    - Check with the SIM provider whether a unique "secondary" phone number is already associated with each device, and use the secondary phone number to identify the intended device if available.

-    # Identifying a device from the access token
-
-    This specification defines the `device` object field as optional in API requests, specifically in cases where the API is accessed using a 3-legged access token, and the device can be uniquely identified by the token. This approach simplifies API usage for API consumers by relying on the device information associated with the access token used to invoke the API.
-
-    ## Handling of device information:
+    ## Identifying the device from the access token
 
-    ### Optional device object for 3-legged tokens:
+    This API requires the API consumer to identify a device as the subject of the API as follows:
+    - When the API is invoked using a two-legged access token, the subject will be identified from the optional `device` object, which therefore MUST be provided.
 
-    - When using a 3-legged access token, the device associated with the access token must be considered as the device for the API request. This means that the device object is not required in the request, and if included it must identify the same device, therefore **it is recommended NOT to include it in these scenarios** to simplify the API usage and avoid additional validations.
+    - When a three-legged access token is used however, this optional identifier MUST NOT be provided, as the subject will be uniquely identified from the access token.
 
-    ### Validation mechanism:
+    This approach simplifies API usage for API consumers using a three-legged access token to invoke the API by relying on the information that is associated with the access token and was identified during the authentication process.
 
-    - The server will extract the device identification from the access token, if available.
-    - If the API request additionally includes a `device` object when using a 3-legged access token, the API will validate that the device identifier provided matches the one associated with the access token.
-    - If there is a mismatch, the API will respond with a 403 - INVALID_TOKEN_CONTEXT error, indicating that the device information in the request does not match the token.
+    ### Error handling:
+    - If the subject cannot be identified from the access token and the optional `device` object is not included in the request, then the server will return an error with the `422 MISSING_IDENTIFIER` error code.
 
-    ### Error handling for unidentifiable devices:
+    - If the subject can be identified from the access token and the optional `device` object is also included in the request, then the server will return an error with the `422 UNNECESSARY_IDENTIFIER` error code. This will be the case even if the same device is identified by these two methods, as the server is unable to make this comparison.
 
-    - If the `device` object is not included in the request and the device information cannot be derived from the 3-legged access token, the server will return a 422 `UNIDENTIFIABLE_DEVICE` error.
+    ## Multi-SIM scenario handling
 
-    ### Restrictions for tokens without an associated authenticated identifier:
+    In multi-SIM scenarios where more than one mobile device is associated with a phone number (e.g. a smartphone with an associated smartwatch), it might not be possible to uniquely identify the device for which the reachability status should be returned from that phone number. If the phone number is used as the device identifier when querying in a multi-SIM scenario, the API may:
+    - respond with an error, or
+    - return a combined reachability status for the multi-SIM group as a whole, or
+    - return the reachability status for a single device in the multi-SIM group, which may not be the intended device.
 
-    - For scenarios which do not have a single device identifier associated to the token during the authentication flow, e.g. 2-legged access tokens, the `device` object MUST be provided in the API request. This ensures that the device identification is explicit and valid for each API call made with these tokens.
