MVNO in Mexico and Latin America: market, hosts and platform needs

Mexico is Latin America’s reference MVNO market: Walmart’s Bait passed roughly 20 million lines in 2025, and Mexican MVNOs together held 15.9 per cent of the mobile market, ahead of Movistar (TeleSemana reading IFT data, August 2025). GSMA Intelligence counted a near fivefold rise in Latin American MVNOs over a decade, and Omdia expects 10.6 per cent annual growth in the Americas. Mexico is unusual in having a wholesale network; elsewhere in the region you negotiate bilaterally with a host.

Walmart’s Bait passed roughly 20 million lines in Mexico in 2025, and Mexican MVNOs together held 15.9 per cent of the mobile market, ahead of Movistar, according to TeleSemana’s reading of IFT data (August 2025). A retailer’s mobile brand overtaking a global operator’s local subsidiary is the kind of event that gets boards elsewhere in the region asking whether they should have a SIM in the wallet too. Whether they should depends less on ambition than on three things: which wholesale model the country offers, which segment the brand can credibly serve, and whether the platform behind the brand can run Spanish-language prepaid at scale. In Spanish the operator is an OMV, operador móvil virtual, and the search phrase “OMV México” is now a business question as much as a telecom one.

The market in one table

GSMA Intelligence (November 2025) counted 2,138 MVNOs worldwide in August 2025 and noted that the number of MVNOs in Latin America had grown almost fivefold in a decade. The same report puts the regional story in context: 58 per cent of countries worldwide still have no MVNO at all, so Latin America’s growth came from a small number of markets opening up rather than from the whole region moving at once. Omdia (February 2025) expects MVNO subscriptions in the Americas to grow at 10.6 per cent a year between 2023 and 2029, behind the Middle East and Africa but well ahead of Europe, where the same forecast has the base contracting.

Two markets carry most of the regional numbers, and they work differently.

Two things stand out. Mexico’s MVNO share is a consumer story, led by one retailer’s brand. Brazil’s is a machine story: the two largest holders of MVNO accesses, Datora with 34 per cent and Surf with 30 per cent, are IoT and M2M specialists, and a bank’s consumer brand became the largest credentialed MVNO only in April 2026. A plan that treats “Latin America” as one market will get at least one of these countries wrong. The regional picture beyond these two, and how it compares with Africa, is set out in the LatAm and Africa market overview.

Mexico’s wholesale network versus bilateral host deals elsewhere

Altán Redes is Mexico’s wholesale shared network, and hosting MVNOs is part of what it exists to do. That single fact changes the shape of a Mexican launch. In most of the region, and in most of the world, an MVNO negotiates with a retail MNO that is also its competitor for the same customers. The host’s wholesale team has to weigh the revenue from your traffic against the risk to its own brands, and that calculation, not the technical work, is usually what sets the pace of the host and legal stage. A wholesale-only network has no retail brand to protect. Its commercial interest and yours point the same way.

That does not remove the decision. A Mexican brand still chooses between the wholesale network and the retail MNOs as host, and between renting a host’s or enabler’s stack and running its own BSS. What the wholesale model does is make the second choice more open. When the host’s business is hosting, the interfaces for provisioning, charging and mediation are built to be reused across many operators, which suits a Medium MVNO that wants its own catalogue and charging engine on top. Our sources do not publish Altán’s wholesale terms or interface specifications, so the point is structural rather than a claim about price, and terms have to be confirmed in negotiation as anywhere else.

Brazil illustrates the other model. Its 11.3 million MVNO accesses were built on bilateral agreements with the national operators, and the market grew at 73.5 per cent a year on that basis (TELETIME on Anatel data, July 2026). Bilateral works. Its costs are that each host has its own interface set, its own onboarding calendar and its own view of which tenant segments it welcomes, and that the MVNO’s platform must be able to take a second host without re-platforming if the first relationship sours. Multi-host readiness is a design requirement in a bilateral market and a convenience in a wholesale one.

A view, since the numbers support one. In Mexico the wholesale network lowers the cost of the own-BSS route, so a brand with real pricing logic (a retailer paying data for spend, a bank linking plans to accounts) should plan for Medium from the start. In Brazil and the rest of the region, the host and legal stage is the critical path exactly as it is in South Africa or Europe, and the platform decision should follow the host decision, not precede it.

The segments that are growing

Retail led in Mexico and has a long history in the region. Bait’s roughly 20 million lines (TeleSemana on IFT data, August 2025) rest on the same mechanics as retail MVNOs everywhere: the store is the distribution point, the loyalty programme is the pricing engine, and the SIM keeps the shopper inside the brand. Carrefour Mobile, live in Belgium, Spain, Italy, Greece, Poland and Brazil, shows the format travels between continents. What a retailer’s BSS has to do differently, and where loyalty-to-data conversion sits in the catalogue, is on the retail MVNO page.

Fintech is the newest consumer segment and the fastest-moving. Nubank’s NuCel reached one million customers in June 2026 and became Brazil’s largest credentialed MVNO by Anatel accesses in April 2026 (Nubank; TELETIME, June 2026). The bank already holds the customer’s identity, payment instrument and app, so registration and recharge happen where the customer already is. The banking specifics, from account-linked plans to card-spend rewards, are on the banking MVNO page.

IoT and M2M is the largest segment in Brazil by accesses, with Datora at 34 per cent and Surf at 30 per cent (TELETIME on Anatel data, July 2026), and it is growing globally. Kaleido Intelligence (May 2026) counts 290 million IoT MVNO connections in 2025 and expects 600 million by 2031, with revenue rising from 2.8 to 6.4 billion dollars. An IoT MVNO’s platform looks nothing like a consumer one: thousands of SIMs per account, tiny per-SIM revenue, pooled data plans, connectivity management APIs and enterprise invoicing rather than prepaid recharge.

Corporate demand is the fourth line. TELETIME’s reading of Anatel data (July 2026) attributes Brazil’s MVNO growth especially to corporate demand, and the corporate MVNO’s requirements are close to the IoT one’s: sponsored usage, limits per employee and cost centre, converged invoicing with fixed and managed services. The scenarios and the reasons an ICT provider adds mobile to hold the account are on the enterprise MVNO page.

Platform requirements for a Latin American MVNO

A European or South African BSS configuration does not transfer to Latin America unchanged. Six requirements come up in every scoping conversation for the region, and each is a platform decision rather than a marketing one.

Language first. Customer care, self-care, the app, notifications and invoices must be in Spanish, or in Portuguese for Brazil, as the primary language, with the terminology customers actually use: recarga, saldo, plan, factura. A translated English interface is not the same thing, and the care team’s tools must match what the customer sees. Plan the language layer as part of the catalogue and CRM configuration, not as a final translation pass.

Prepaid and cash recharge second. Most of the regional base is prepaid, and a large share of recharges is still cash, paid at convenience stores, kiosks and pharmacies that act as cash-recharge networks. The BSS has to accept top-ups from those networks in real time, reconcile them daily, apply the credit to the right balance and handle the commission structure. Card, wallet and app recharge sit alongside cash, not instead of it, and the charging system must apply credit within seconds because the customer is standing at the counter waiting for the confirmation SMS.

Tax and invoicing third. Electronic invoicing and tax rules differ by country, and in several markets the invoice format, numbering and submission to the tax authority are prescribed. The billing system needs a localisation layer for tax calculation, invoice layout and fiscal reporting per country, maintained as rules change. Confirm the current requirement with local tax advisers for each market before the platform stage, because it shapes the invoicing design, not only a template.

KYC fourth. Subscriber registration rules are set per country by the regulator, IFT in Mexico and Anatel in Brazil, and one country’s flow should not be assumed to work in another. Plan for a configurable registration flow: which identity documents, which checks against which registries, what happens on failure, and who stores the record and answers a regulator’s request for it. Where a bank or retailer already holds a verified identity, the platform should reuse it rather than asking the customer to register twice.

Multi-host fifth. In a bilateral market a second host is insurance; in Mexico it may mean the wholesale network for one segment and a retail MNO for another. Either way, provisioning, charging and mediation interfaces should be modelled per host on one platform, with the catalogue and subscriber records above them, so that a host change is an integration and not a migration.

eSIM sixth. NuCel’s growth shows digital-first activation works in the region, and a fintech or retail brand with an app should offer eSIM from launch. The platform has to handle profile ordering, download and swap alongside physical SIM inventory, with the same registration flow on both. The launch stages, from Discovery through the host and legal track to integrations, are in the launch guide.

Regulatory checklist

A BSS vendor is not the right source for a country’s licensing conditions, and this article does not set them out. What it can do is list the items that appear on every regional launch plan and say who confirms each. The regulators of record are IFT for Mexico and Anatel for Brazil; other countries have their own, and each requirement below must be confirmed with the relevant regulator and local counsel.

• Authorisation or registration of the MVNO with the regulator, and any conditions attached to it. Brazil’s MVNOs are credentialed by Anatel; confirm the current procedure, its timeline and what the host requires from you before signing.
• Subscriber registration and identity verification: which documents, which checks, where the record is stored and who answers regulator requests. Set per country; confirm with the regulator.
• Numbering and number portability: how numbering resources are allocated to an MVNO, and the porting process, calendar and party of record. Plan certification as a long-lead integration.
• Electronic invoicing and tax compliance: invoice format, tax calculation and any prescribed submission to the tax authority. Confirm with local tax advisers per country.
• Data protection: where subscriber data resides, what the host or enabler may do with it, and how consent and retention are implemented in the BSS. Counsel’s work; the BSS must be able to implement the outcome.
• Lawful interception and regulatory reporting hand-off between the host, the MVNO and the BSS vendor, written into the technical annex of the host agreement.
• Consumer protection rules on tariffs, contract terms and complaint handling, which shape how the catalogue and care processes are configured.

None of these items sets the launch stages. They lengthen the host and legal stage and add integrations to the platform stage, which is why they belong in Discovery and not in a compliance review after the platform contract is signed.

A realistic timeline

Avante plans a Medium MVNO, own BSS on a host, at four to six months from the point the host agreement and legal framework are confirmed, and a Full MVNO at eight to ten. Platform readiness for a standard mono-MVNO is about three months. The stages are the same in the region as elsewhere: Discovery of two to three weeks; the host and legal track as the critical path; the BSS platform in four to eight weeks; integrations in six to twelve weeks, partly in parallel; launch in two to four weeks.

What Latin America adds is weight in two stages. Discovery carries the language, tax and KYC scoping described above, and the integration stage carries cash-recharge networks, electronic invoicing and per-country registration flows on top of the host interfaces. A brand launching in two countries should treat the second as a separate integration stream on the same platform, not as a copy of the first. One calibration point from outside the region: a leading banking MVNO in the CIS was delivered on Avante in six months to the bank’s security and integration requirements.

Where Avante fits

Avante is a BSS vendor, not an enabler. It supplies the platform an MVNO runs when it chooses its own BSS on a host, the Medium and Full models: product catalogue, online charging (Avante OCS), convergent billing, CRM, self-care, mediation and provisioning, with host, payment, recharge, KYC and eSIM integrations, delivered on-premises, in a private cloud or as a managed service. The same stack runs as a multi-tenant MVNE and MVNA platform for operators and aggregators hosting several brands, which is the form an enabler in a bilateral market would use. Latin America is a priority region for Avante alongside Africa. Its published references are in Africa, Europe and the CIS, and it does not claim a Latin American customer; the language, tax and recharge localisation described above is scoped in Discovery for each market.
