Telecom's Quiet Unbundling 

The small plastic rectangle that has defined the mobile industry for thirty years is quietly disappearing, and its exit marks the real edge of telecom transformation. For most of its history a mobile operator owned the entire chain: the same company built the network, issued that SIM, set the plan, ran the store, and answered the phone when something broke.  

Those functions were fused together because the technology gave no other option; the card was the lock that held them in place. Remove the lock, and the fusion dissolves, a century-old bundle separating into distinct layers that no longer belong to the same owner. 

Other industries have already been through this exact separation, so the mechanism is not a mystery. It is worth understanding how the bundle comes apart, because the sequence is further along in telecom than most balance sheets yet reflect. 

The separation is a familiar mechanic 

The same pattern repeats across industries: a digital layer slides between the infrastructure and the customer, and the two, once inseparable, begin to operate independently.  

Banking shows it in the numbers. In McKinsey's 2026 Global Banking Annual Review, the share of revenue held by the world's largest fintechs, measured against the largest banks, climbed from 10 percent in 2021 to 17 percent in 2025, while those fintechs came to represent roughly 37 percent of the group's market value. The deposits never left the banks; the customer relationship, and the value attached to it, moved to the layer on top. 

Media separated the same way. In 2025, global streaming revenue overtook traditional pay-TV for the first time, according to Omdia , with online video reaching $176 billion as pay-TV slipped to $170 billion, and streaming now holding more than two-thirds of the world's TV and video subscriptions. The cables and satellites still carry the signal. The audience, and its revenue, moved up a layer. 

Telecom is the same mechanic on a slower clock, and until recently it was the hardest industry to unbundle, because one physical object held the whole stack together. 

Why telecom transformation runs through the SIM 

That object is the SIM. As long as reaching a network meant holding its plastic card, access, service, and distribution stayed welded together. The card was a physical lock binding the customer to a single operator's storefront and supply chain. 

The eSIM removes the lock. When the SIM becomes a software profile, provisioning stops being a shipment or a counter transaction and becomes something any authorized party can do remotely. The scale of that change is no longer speculative: GSMA Intelligence puts eSIM penetration in smartphones at 5 percent at the end of 2025, doubling to 10 percent through 2026 and doubling again in 2027, with eSIM connections set to outnumber removable SIMs by 2030. 

The clearest sign that the layers are already pulling apart is where the customer now meets connectivity. GSMA Intelligence reports that only 8 percent of eSIM-aware consumers first learn about it through their own operator's commercial channels. The network is one company's asset; the moment of sale increasingly belongs to someone else. That gap between owning the network and owning the sale is the unbundling made visible. 

The four layers, coming apart one by one 

Pull the four layers apart and a quiet reversal becomes obvious: the parts that cost the most to build are no longer the parts worth the most to own. 

• The network is the first: spectrum, towers, and the core. It stays capital-intensive and essential, and it is the hardest layer in the stack to replicate. It is also, as banking and media both discovered, the layer where owning the asset stops guaranteeing the customer. 
• Access is the second, and it is the layer eSIM has rewritten. Putting a subscription on a device is now a software event that can happen anywhere, instantly, with no logistics attached. 
• Service is the third: the plan, the price, and the brand a customer believes they are buying. Mobile virtual operators and travel connectivity brands already sell service over networks they do not own, and it is the fastest-moving corner of the market, with Juniper Research forecasting global travel eSIM revenue to climb from $1.8 billion in 2025 to $8.7 billion by 2030. eSIM strips out the last operational friction that slowed them. 
• Distribution is the fourth, and increasingly the one that decides where value lands. Connectivity is sold inside a travel booking, at an app's checkout, as a benefit on a bank card. The customer meets connectivity at the moment of need, and the company that owns that moment is often not a telecom company at all. 

What separation leaves for operators 

The uncomfortable part of the analysis, for operators, is not that the network loses importance. It does not. The risk is the one banking incumbents came to know well: becoming the essential but low-margin layer at the bottom while the profitable customer relationship settles into the service and distribution layers above. An operator that treats eSIM as just a new way to ship its own SIM has misread the moment. An operator that treats it as a way to push its network capacity through a hundred new distribution partners has read it correctly. 

Reaching those partners is itself a capability, and it is where the newest entrants have concentrated. This is the position Monty Mobile built toward.  

The Monty eSIM Hub sits at the wholesale and orchestration layer of the unbundled stack, holding the operator agreements, remote provisioning, multi-network routing, and settlement that let a bank, an airline, a platform, or an emerging operator offer connectivity under its own brand without building a network. The infrastructure is handled once, centrally, so the businesses at the distribution layer can concentrate on the customer they already own. 

None of this is a forecast. It describes telecom industry trends already legible in the data, moving in the same direction they moved in finance and media. The layers have separated. The SIM is going soft and demand is arriving through doors the operator does not control. 

Industries rarely announce their turning points; they pass through them quietly and only look inevitable in hindsight. The telecom transformation now underway is one of them, and the future of telecommunications will be settled less by who owns the network than by who owns the layers above it. Once the bundle separates this way, a single question decides the outcome, which layer captures the value, and that is the question our companion piece, The Connectivity Platform Era, takes up in full. 

FAQ 

What does "unbundling" mean in telecom? 

Unbundling is the separation of functions a single operator once owned together ; the network, access and the SIM, service and plan, and distribution into distinct layers that different companies can own and run independently. eSIM is a primary driver, because it turns the SIM from a physical object into a software profile that parties other than the network owner can provision. 

Is telecom transformation the same thing as 5G? 

No. A network generation like 5G changes what the infrastructure can do. The transformation described here is structural rather than technical: it changes who owns the customer relationship and where value accumulates in the industry, regardless of the network generation underneath. 

What does telecom unbundling mean for mobile operators? 

It does not make the network less important, but it changes where the profit sits. As service and distribution separate into their own layers, operators risk holding the costly infrastructure while other companies own the customer relationship and its margin. The operators best positioned are those that treat their network as capacity to be distributed through many partners, rather than something sold only through their own storefront. 

How can a company sell connectivity without owning a network? 

By operating at the service and distribution layers and connecting to a wholesale provider that holds the network agreements and provisioning infrastructure. Through a hub model, a brand, bank, or platform offers connectivity to its own customers while the underlying operator relationships, routing, and settlement are managed centrally by the wholesale partner.
