How Are Software and Telecom Services Distinguished in ISIC Rev. 5?

Software and telecom services are distinguished in ISIC Rev. 5, UN Statistics Division, by function. Software services write, modify, host or support code that performs a task. Telecom services operate networks and transmit voice, data, text, sound or video between users. A video call illustrates both at once: software provides the app and its features, while telecom provides the network that carries the call, and each side is described in its own entry.

What work does each side actually do during a video call?

A video call is the clearest way to see the two functions side by side. On the software side, a team writes the application, designs its screens, adds features such as screen sharing and chat, fixes faults, and runs the servers that hold accounts and route requests inside the application. On the telecom side, an operator runs the network that carries the call: the wired links, the mobile base stations or the satellite links, and the switches that move voice, data, text, sound and video between users. The caller notices one smooth conversation, but two different kinds of work make it possible. One creates and maintains code that performs tasks. The other operates facilities that transmit signals for others. ISIC Rev. 5, UN Statistics Division, describes each side in its own entry because the economic functions differ, even when they reach the user as a single experience.

How does a messaging app and its mobile carrier divide the job?

Expand the messaging example. A company sells a messaging app, maintains its code, adds new features, and runs its own servers to store messages and manage accounts. It does not own mobile masts and does not hold spectrum. When a user sends a message, the app prepares it and hands it to the network, and a mobile operator carries it over its network to the recipient’s phone. The app company earns from its software and hosting service, while the operator earns from carrying traffic and selling subscriptions for network access. If the app company later buys network capacity in bulk, it still does not become a network operator in descriptive terms, because buying capacity is not operating a network. Conversely, if the operator sells its own branded app, that app work is described separately from its network work. Reading the two businesses task by task keeps each income stream in the right total.

What mistakes blur the line between an app seller and a network operator?

Three mistakes recur. The first is to describe a network operator as a software company because it sells an app, when most of its work and income come from operating networks. The second is the reverse: to describe a software company as a telecom operator because its app makes calls, when it owns no network and buys carriage from others. The third is to count the same subscription twice, once as software income and once as telecom income, because the customer paid one price for a bundled service. Content creation adds a fourth confusion, since a firm that makes videos or articles is neither writing the app that shows them nor carrying the signals that deliver them. In each case the remedy is the same: set the brand and the bundle aside, list the tasks the unit actually performs, and match each task to the UNSD wording in ISIC Rev. 5, UN Statistics Division, with the principal activity deciding the overall placement.

Why do regulators need two totals rather than one digital figure?

Regulation gives the distinction practical force. Telecom operators face rules on spectrum, interconnection, coverage and emergency access, because they control scarce network resources that other services depend on. Software providers face a different set of rules, on data handling, safety, competition in app markets and consumer terms, because they control code and platforms rather than networks. A single blended digital total would hide which market a policy was affecting and make it hard to judge whether a rule helped networks, software, or neither. Statistical separation lets regulators and analysts apply the right lens to each market. ISIC Rev. 5, UN Statistics Division, contains 22 sections from A to V, with 87 divisions, 258 groups and 463 classes in total, so a boundary shift between software and telecom groups can change both regulatory pictures at once.
