Why Most ISPs Are Thinking About Mobile and MVNO Strategy the Wrong Way

Most ISPs do not need to launch an MVNO. A mobile strategy only becomes coherent when four things line up: a customer relationship worth extending, a real point of differentiation, economics that actually work, and OSS/BSS systems ready to handle 30-day billing and usage-based reporting.

There is a familiar pattern in retail telecom. An operator does something new, the trade press covers it, and within a few cycles the narrative shifts from “some operators are exploring this” to “every ISP needs to do this or risk being left behind.” With how often “MVNO” is showing up lately, that shift seems to be starting around mobile.

That take is not entirely wrong. There is real movement here. But the more productive question is not whether mobile belongs in the ISP playbook. It’s whether it belongs in yours.

What the Members Mobile MVNO launch revealed

Recently, we supported the launch of a new MVNO, and that gave us a close look at one version of how this can work. Members Mobile is a credit union-focused MVNO built around a specific audience, with a clear point of differentiation and a model that ties service, loyalty, and financial participation together. Sonar Software’s role was to support the billing and reporting infrastructure behind it: a 30-day billing structure and the subscriber payout-related workflows that power their ShareBack program. For us, it was a useful exercise in understanding how our products apply in a new market context and where they can deliver real operational value.

sonarPay matters here too, because once billing gets more dynamic, payments and payouts stop being back-office mechanics and start shaping the customer experience. That was part of what we saw in supporting Members Mobile. The 30-day billing structure and ShareBack-related reporting were not just operational details. They were part of making the model work in practice.

The launch matters less than what it reveals about when a mobile strategy becomes coherent.

The four tests for a coherent ISP mobile strategy

In my experience, it tends to come down to four things.

First, you need a customer relationship that is worth extending. A subscriber who barely recognizes your brand is not a great candidate to buy mobile from you. The operators with the most credible path into this space are those who have already built something durable with their customers. Trust is the real infrastructure. Coverage is something you lease.

Second, you need a reason to be different that goes beyond “we also sell mobile now.” The MVNO market is not short on options for consumers, and if your pitch is price parity plus convenience, you have entered a commoditized conversation before it starts. Members Mobile has a genuine differentiator because the credit union relationship gives it a distinct angle. Without that kind of differentiation, you are competing on a playing field that favors the incumbents. If you are only planning to sell mobile to your existing ISP customers, that may be enough. If your ambitions include selling beyond your current customer base, sharper differentiation becomes essential.

Third, you need to understand the economics, not just the narrative. Mobile is often positioned as a way to improve retention and wallet share, especially in regional and rural markets where operators already have strong local relationships. But mobile can also introduce complexity, customer service overhead, and margin pressure that quietly eats your gains. The operators who should move forward are the ones who have done the math.

Fourth, your systems need to be ready. The billing model for mobile is not the same as broadband. Thirty-day cycles and usage-based reporting are addressable, but they require real operational infrastructure to support them. If you treat this as an afterthought, you will not be able to swivel-chair your way out of it.

Where Sonar fits, and where it doesn't

I want to be direct about where Sonar fits today. We can credibly support billing, workflows, and payments for models like this. That is what Members Mobile demonstrated. Sonar is not a full MVNO or MVNE stack, and operators evaluating a new mobile offering need to understand exactly what their partners can and cannot do. Clarity on that is more useful than vendor theater. Ask the hard questions early, and ask for receipts.

Why mobile is a stronger play for regional and rural ISPs

Where I do see real opportunity is for regional and rural operators thinking about mobile as part of a more deliberate bundle strategy. The traditional MVNO playbook leans on scale. These operators can lean on proximity instead. Your customers already trust you. They know your name. You answer the phone when they call. In that context, mobile can deepen the relationship rather than just adding a line item. That is a different proposition from what a national carrier can offer, and it deserves a hard look.

So no, I do not think every ISP should be building an MVNO. The math will not work for most. The operational lift is real. The differentiation problem is harder than the headlines suggest.

But I do think more operators should be asking the question carefully: what would it take for this to make sense for us, what partner model would support it, and are our customer relationships and systems actually strong enough to carry it?

That is a more productive starting point than waiting for industry consensus to harden.

Frequently asked questions

Should every ISP launch an MVNO? No. For most operators the economics will not work, the operational lift is real, and the differentiation problem is harder than the headlines suggest. The better move is to ask carefully what it would take for mobile to make sense for your specific business.

How did Sonar support the Members Mobile launch? Sonar supported the billing and reporting infrastructure behind this credit union-focused MVNO, including a 30-day billing structure and the subscriber payout workflows that power its ShareBack program. Sonar is not a full MVNO or MVNE stack.

Why does mobile billing differ from broadband? Mobile relies on 30-day cycles and usage-based reporting rather than standard broadband billing. Those requirements are addressable, but they need real operational infrastructure, not a swivel-chair workaround bolted on as an afterthought.
