# DataSession Resource The SIM **DataSession** resource returns data session information for a [SIM](https://docs.korewireless.com/en-us/api/products/programmable-wireless/wireless-sim-resource) over a period of 30 days or less in an aggregated list. A data session represents an individual data connectivity session between the SIM-connected device and a service that interfaces between the cellular network and the Internet. This will be a [PDP context](https://en.wikipedia.org/wiki/GPRS_core_network#PDP_context) either via a PDN connection or a Packet Gateway. You can think of a data session as a representation of your device's Internet connection, whenever such a connection exists. Data sessions can be used to troubleshoot device issues and understand the network setup and teardown behavior of a device in the wild. *** ## DataSession Properties **sid** string The unique string that we created to identify the DataSession resource. *** **sim\_sid** string The SID of the [Sim resource](https://docs.korewireless.com/en-us/api/products/programmable-wireless/wireless-sim-resource) that the Data Session is for. *** **account\_sid** SID\ The SID of the Account that created the DataSession resource. Pattern:`^AC[0-9a-fA-F]{32}$` Min length:`34` Max length:`34` *** **radio\_link** string The generation of wireless technology that the device was using. *** **operator\_mcc** string The 'mobile country code' is the unique ID of the home country where the Data Session took place. See: [MCC/MNC lookup](http://mcc-mnc.com/). *** **operator\_mnc** string The 'mobile network code' is the unique ID specific to the mobile operator network where the Data Session took place. *** **operator\_country** string The three letter country code representing where the device's Data Session took place. This is determined by looking up the `operator_mcc`. *** **operator\_name** string The friendly name of the mobile operator network that the [SIM](https://docs.korewireless.com/en-us/api/products/programmable-wireless/wireless-sim-resource)-connected device is attached to. This is determined by looking up the `operator_mnc`. *** **cell\_id** string The unique ID of the cellular tower that the device was attached to at the moment when the Data Session was last updated. *** **cell\_location\_estimate** object An object that describes the estimated location in latitude and longitude where the device's Data Session took place. The location is derived from the `cell_id` when the Data Session was last updated. See [Cell Location Estimate Object](#cell-location-estimate-object). *** **packets\_uploaded** integer The number of packets uploaded by the device between the `start` time and when the Data Session was last updated. Default:`0` *** **packets\_downloaded** integer The number of packets downloaded by the device between the `start` time and when the Data Session was last updated. Default:`0` *** **last\_updated** string\ The date that the resource was last updated, given as GMT in [ISO 8601](https://www.iso.org/iso-8601-date-and-time-format.html) format. *** **start** string\ The date that the Data Session started, given as GMT in [ISO 8601](https://www.iso.org/iso-8601-date-and-time-format.html) format. *** **end** string\ The date that the record ended, given as GMT in [ISO 8601](https://www.iso.org/iso-8601-date-and-time-format.html) format. *** **imei** string The 'international mobile equipment identity' is the unique ID of the device using the SIM to connect. An IMEI is a 15-digit string: 14 digits for the device identifier plus a check digit calculated using the Luhn formula. *** ### Cell Location Estimate Object The Cell location estimate object reports the approximate location of the cellular tower that the device was connected to when the Data Session was last updated. This is based on a lookup of public cellular tower data, and is not necessarily an accurate description of the cellular tower. It is not intended to describe the location of the SIM-connected device itself. | Property | Description | Empty Value | | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | ----------- | | `lat`Integer | Latitude. The spherical coordinate value of the estimated cellular tower location parallel to the Equator. | 0 | | `lon` Integer | Longitude. The spherical coordinate value of the estimated cellular tower location from the geographical North Pole to the geographical South Pole. | 0 | ## Read multiple DataSession resources {% openapi src="/files/J4rPRhkD7uutXjbzb7DT" path="/v1/Sims/{Sid}/DataSessions" method="get" %} [openapi3\_0 (alf).yaml](https://3487028960-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJknMM6SZJYk9EbbitKp5%2Fuploads%2F4alsAWeuMtriesOfOixr%2Fopenapi3_0%20\(alf\).yaml?alt=media\&token=8a6481d4-a087-4460-b7cd-9e4a4d0e6341) {% endopenapi %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
