Key takeaways
ISPs and fiber operators can launch their own branded mobile service as an MVNO, using a carrier's network and a mobile enablement partner, without building towers. With the right partner, launch takes weeks, and mobile can run alongside your existing billing system, on the same bill as broadband. The key decision is the partner: look for one that fits your billing, brand and support team, rather than replacing them.

Why ISPs are launching their own mobile service
Home internet is getting harder to differentiate. Customers compare on speed and price, and switching is easy. Adding mobile under your own brand helps you:
• Reduce churn. Households that buy internet and mobile together are less likely to leave.
• Earn more per household. Every mobile line adds monthly revenue on top of broadband.
• Offer a stronger bundle. Internet, TV, phone and mobile from one provider, often called quad play.
Some of the largest US cable companies already run their own mobile brands as MVNOs on a major carrier's network. Regional ISPs and fiber operators can now do the same at a much smaller scale.
How can an ISP launch its own branded mobile service?
An ISP launches mobile as an MVNO (mobile virtual network operator): it sells mobile plans under its own brand on a carrier's network. There are three ways to do it:
| Build it yourself | MVNO-in-a-box | Mobile enablement partner (MVNE) |
What it means | Negotiate with a carrier and build your own systems | Use a partner's ready-made app, billing and support | Connect mobile to your own billing, CRM and app |
Time to launch | A year or more | Fast | Within weeks |
Your brand and app | Full control | Partner's app and processes | Full control |
Best for | Very large operators | Testing demand | Most ISPs |
Most ISPs follow the same five steps:
1. Pick your first customers. Decide which households to offer mobile to first, and the bundle discount.
2. Choose your partner and network. Compare coverage in your service area, integrations and launch timelines.
3. Keep plans simple. Start with two or three plans and add more later.
4. Connect billing and support. Mobile should appear on the same bill and in the same support tools as broadband.
5. Soft launch, then scale. Test with employees and loyal customers, then market to your full base.
Which companies help fiber operators launch an MVNO?
Several types of companies are involved. Most ISPs work with one main partner that brings the others together:
Partner type | What they do |
Mobile enabler (MVNE) | Provides the technology: billing and charging, SIM and eSIM activation, number porting, and carrier integrations. This is usually the ISP's main partner. |
Aggregator (MVNA) | Buys network capacity from carriers in bulk and resells it to smaller MVNOs. |
Host carrier (MNO) | Owns the mobile network. Large operators sometimes contract directly; most ISPs connect through an MVNE or MVNA. |
MVNO-in-a-box provider | Bundles network, app, billing and support into one packaged service, with less control over the brand and experience. |
Telgoo5 is an MVNE: it provides the technology and carrier integrations ISPs need to launch mobile under their own brand.
How much does it cost, and how long does it take to launch?
Cost depends on how much you build yourself. Building your own systems means large upfront costs and often a year or more of work. With a mobile enablement partner, upfront costs are much lower and an ISP can launch within weeks.
The main ongoing costs are:
• Wholesale network usage: what you pay for the mobile data, calls and texts your customers use.
• Platform fees: for billing, activation and other technology from your partner.
• Devices and SIMs: physical SIMs and any phones you choose to sell (eSIM lowers SIM costs).
• Marketing and support: promoting the bundle and handling mobile customer questions.
Can an ISP add mobile without replacing its existing billing system?
Yes. A modern mobile enablement partner connects to your current billing system through APIs. Mobile charges, such as plan fees and extra usage, flow into the billing system you already use, so your billing and finance teams keep working the way they do today.
Some ISPs use the launch as a chance to replace older billing systems. In that case, a converged platform can bill broadband and mobile together. Either way, you don't have to replace your billing system just to add mobile.
How can an ISP combine broadband and mobile on one bill?
There are two common ways:
• Send mobile charges to your current billing system. Your partner rates mobile usage and passes the charges to your billing system, which adds them to the household's broadband bill.
• Bill everything on one converged platform. Broadband and mobile are set up as products in the same system, with bundle discounts applied automatically.
In both cases, customers get one bill, one payment and one account, which is a big part of why bundles reduce churn.
What options are available for outsourced mobile customer support?
Mobile support questions are different from broadband: SIM and eSIM activation, number porting, coverage and roaming. ISPs usually choose one of three models:
Model | How it works | Best for |
In-house support | Your team handles all questions, using the partner's support tools to see mobile lines, usage and SIM status. | ISPs with an experienced support team |
Shared support | Your team answers first-line questions; the partner handles technical issues like activation, porting and network problems. | Most ISPs at launch |
Fully outsourced | A partner provides branded support for mobile on your behalf. | ISPs that want to keep their team focused on broadband |
How can an ISP migrate existing mobile subscribers to a new platform?
Some ISPs already offer mobile through another provider and want to move to a better platform. A good migration keeps customers' phone numbers and service working with as little disruption as possible:
1. Audit your data. Customer accounts, plans, balances, numbers and SIM details.
2. Check the network. If you stay on the same host network, customers may keep their SIMs; if the network changes, plan for new SIMs or eSIMs and number porting.
3. Migrate in phases. Start with a small group, check billing and service, then move the rest.
4. Tell customers early. Explain what changes, what stays the same and what (if anything) they need to do.
5. Run systems in parallel briefly. Compare bills from the old and new systems before switching off the old one.
What should an ISP look for in a mobile enablement partner?
Look for | Why it matters |
Works with your systems | Connects to your billing, CRM and app, or bills broadband and mobile together on one platform. |
One household bill | Internet and mobile on one invoice, with bundle discounts applied automatically. |
Carrier integrations | Coverage that fits your service area. |
eSIM and in-app activation | Customers add a mobile line from your app in minutes. |
Flexible support options | Support that matches your team, from tools for your agents to fully managed care. |
Migration experience | A proven process for moving existing subscribers without disruption. |
Your brand everywhere | Plans, apps, emails and support carry your brand, not the partner's. |
"ISPs have a big advantage when they launch mobile: they already have the customers, the billing relationship and the trust. When mobile shows up on the same bill and the same app, take-up is much stronger." Eric Nuetzel, VP, Client Operations, Telgoo5 [DRAFT QUOTE: pending Eric's approval]
