Five questions about AI in telecom operations
AI is the lever every operator names in its cost programme, and no annual report puts a currency figure on what it has saved. The three American carriers spent $150.9 billion in 2025 running their networks and serving their customers, within one per cent of what they spent two years earlier. Read the five parts to find out:
- the cost an AI saving is measured against and where it sits in the accounts
- which savings operators have claimed, in which venue, and whether the accounts show them
- ten candidates ranked by what it costs to get a number a finance director would accept
- what 3GPP, O-RAN and the autonomy levels provide and what they leave out
- where to put the kill gate on a pilot, and the two outages that show why

The parts
Part 01The cost an AI saving is measured againstHow large is the cost an AI saving is measured against, and where does it appear in the accounts?Cost of services plus SG&A, which is where any operating AI saving has to land, came to $54.4B at AT&T, $61.6B at Verizon and $35.0B at T-Mobile in 2025. The combined pool moved 0.8% in two years while revenue grew 5.1%. AT&T and Verizon employ 32,370 fewer people than they did two years ago, and their filings put that down to separation programmes and legacy shutdowns, with a severance charge beside each. Only Vodafone files an energy bill: €0.9B for 5,967 GWh.SEC 10-K, 10-Q and 20-F filings · company energy dataPart 02What operators say AI savesWhich AI savings have operators put a number on, in which venue, and can the accounts show them?None of the Forms 10-K and 20-F or annual reports of the eleven operators in this series puts a currency figure on what AI saves. The programme totals treat AI as one lever. AT&T targets $4B a year by the end of 2028 and Verizon $5B of 2026 opex, “with a substantial portion realized by headcount reductions”. T-Mobile expects nearly $3B from “digitalization and AI” by 2027 and BT £3.7B of savings by FY30. The figures that name AI were said on calls, such as Verizon’s $200M of energy with no period and no base, or appear as a share, such as the 34% of enquiries Telstra’s assistant handled.10-K, 8-K and 20-F filings · earnings calls · pressPart 03Ten AI candidates ranked by the cost of finding outWhich AI candidates can produce a trustworthy number cheapest, and what has been published for each?Energy saving ranks first of ten, and it is the only candidate for which an operator has published a national figure. BT’s cell sleep on 19,500 sites saves 4.5 GWh a year, which works out at about 0.63 kWh per site per day against a headline of up to 2 kWh. 3GPP’s own simulations put one technique’s saving anywhere from 0.9% to 84.8%, depending on load. Care has results by journey and no all-contact containment rate with a definition behind it. Field dispatch and procurement have no published baseline at all, and they rank last.Operator releases · TM Forum · 3GPP TR 38.864Part 04What the standards addWhat do 3GPP, O-RAN and the autonomy levels give an operator to build an AI programme on?The 5G core has had an analytics function, NWDAF, since Release 15, but a standard way to monitor whether a model is still accurate arrived only in March 2023, in TS 23.288 v18.1.0. Release 17 limited model sharing to single-vendor environments. The radio study found no consensus for AI-based CSI compression, and Release 19 standardised the one-sided models a single vendor can build, implementable from December 2025. One third-party rApp runs in a live network, AT&T’s since July 2025, and no result from it has been published. China Mobile reports L4 in 21 high-value scenarios, against its 2023 target of L4 by 2025 for “almost all the services”.3GPP · O-RAN Alliance · TM Forum · operator reportsPart 05Where the kill gate goesWhich rules and which failures decide where an AI pilot must stop, and what should it measure while it runs?At Rogers in 2022 “the risk assessment algorithm downgraded the risk level” to Low on the change that cut off over 12 million customers. After AT&T’s outage of 22 February 2024, which blocked more than 92 million calls, the FCC wrote that loading such changes “should not be possible”. AI voices need prior express consent under FCC 24-17, EU chatbots have had to say what they are since 2 August 2026, and Regulation 2026/1744 moves the high-risk duties for critical infrastructure to 2 December 2027. The first gate goes where no automated tool can lower a change’s risk class.FCC · CRTC · EU AI Act · Colorado · 3GPP
