As 5G picks up speed, the new networks will co-exist with the existing 4G ones in the coming years. For Communication Service Providers (CSPs), flexibility in balancing cost-optimized versus performance optimized network deployment is crucial to maximize profitability and take advantage of the wide range of business opportunities.

Basically, it means they need to have the option to migrate to 5G in their own time and in alignment with their business needs.

The journey to 5G Core is not simple, though, and will imply a technology shift with the adoption of a new 3GPP defined network architecture (service-based architecture) and new network functions built on cloud native technology. With service providers’ needs and concerns in mind we have developed the dual-mode 5G Core solution.

Dual-mode 5G Core provides that kind of desired control by combining Evolved Packet Core (EPC) and 5G Core network functions into a common cloud native platform. CSPs can get the most out of cloud native, microservices and user plane performance by implementing the dual-mode core solution as the best way for efficient control of Total Cost of Ownership (TCO) while smoothly migrating to 5G.

As hard as it sounds to achieve challenging business and operational goals while migrating to a 5G Core, with dual mode it is possible.

If we look at Ericsson’s dual mode 5G Cloud Core solution, it is fully based on cloud native principles, with software architecture being based on microservice technology.

This is to ensure that the underlying infrastructure will have better capacity and elasticity, which in turn will offer high levels of orchestration and automation for operational efficiency.

Dual-mode solution enables CSPs to manage one network instead of two and add programmability to their network. The decomposition of software into microservices facilitates a fast, low-cost method of introducing new services on a small scale.

At the same time, it supports easy and effective scaling of services from hundreds of users to millions and this is exactly how CSPs can address new business opportunities or pursue those that have been difficult to address until now.

While no journey to a future core will be alike, what applies to every CSP is the need to have a holistic view on cost. A report by Ericsson titled “Dual-mode 5G Cloud Core: TCO benefits” highlights that substantial saving is possible in various areas of dual-mode cloud native operations, including:

—   Up to 20 percent of capex in Core network infrastructure

—   Up to 15 percent savings in database infrastructure

—   70 percent OpEx savings in configuration of policies

—   Up to 80 percent cost savings in network integration

—   More than 60 percent reduced OpEx for software upgrades

As 5G evolves, dual mode core supports both Evolved Packet Core (EPC) and 5G core, combining both functionalities and offering a uniform operational maintenance that is able to scale with the speed that 5G use cases demand.

Migrating to a 5G NR SA and 5GC network is crucial for our customers’ success, enabling them to unlock key 5G functionalities like faster speeds, ultra-low latency and advanced network slicing – allowing our customers to support increasingly complex 5G use cases such as automated manufacturing, remote healthcare and connected vehicles.

This migration will also allow service providers to simplify operations and service agility, enhance user experience with better coverage and improve network capabilities.

To secure new 5G revenue streams while continuing to support existing 4G customer base, service providers can begin by introducing 5G New Radio (NR) non-standalone (NSA) and run both generations side by side supported by the Evolved Packet Core while migrating to 5G NR standalone (SA) and a 5GC network.

At Ericsson, we have been learning from previous technology shifts. As we enter 5G era with all its complexity and unknown opportunities, we know the value of migrating networks at own pace and dual-mode 5G Cloud Core solution provides enhancements that enables this vision.

By implementing the dual-mode solution, service providers will have more control to migrate to 5G on their own pace and in alignment to their business needs.

Telcos Resume SIM Card Sales after 2-Week Halt

Telecommunications operators have resumed full SIM swap and related services following a four-week nationwide outage linked to the National Identity Management Commission (NIMC)’s migration to a new verification platform.

Telcos Resume SIM Card Sales after 2-Week Halt

The outage rendered millions of subscribers unable to perform SIM-related tasks such as swaps, replacements, and activations.

Operators in the industry say the disruption began on June 26, 2025 when telcos temporarily halted SIM registrations and swaps due to unforeseen technical challenges during the transition to NIMC’s upgraded identity verification system.

The migration was mandated to enhance the integrity and efficiency of national identity management but caused major service interruptions across all Nigerian networks.

However, July 21, both MTN and Airtel confirmed via their social media handles that SIM swap services have now fully resumed.

MTN announced: “SIM swaps have now resumed. We can confirm that NIMC services are fully operational and appreciate their support in the migration to a new platform for NIN verification services for the telecommunications industry.

In a public update issued via its MTN Nigeria Support handle on X (formerly Twitter), MTN confirmed that SIM swaps have now resumed.

Telecom operators complained that the portal was unreliable or inaccessible, which resulted in the suspension of SIM swaps, number porting, and new SIM registrations, even though NIMC maintained that the platform was operating as intended.

Unexpected technical difficulties arose during the switch to the new platform, according to the Association of Licensed Telecommunications Operators of Nigeria.

Real-time NIN verification for SIM registration, replacement, and network migration was impacted by these issues.

“Unexpected technical difficulties have surfaced, impacting real-time NIN verification for SIM registration, replacement, and porting, following a recent directive from the National Identity Management Commission mandating Mobile Network Operators to transit to a new identity verification platform,” ALTON stated in a previous joint statement signed by Gbenga Adebayo, chairman, and Damian Udeh, publicity secretary.

Nigeria, Others Achieve 84% Adult Mobile Phones Penetration

Published

The World Bank has affirmed that 84 per cent of adults in low-and middle-income economies, including Nigeria, own personal mobile phones.

The bank in its Global Findex 2025 report said mobile phone ownership was widespread and nearly everywhere. It said data from the Global Findex 2025 Digital Connectivity Tracker, revealed that “86 per cent of adults worldwide, and 84 per cent of adults in low- and middle-income economies, own personal mobile phones.”

The report pointed out that mobile phones and the internet had become widespread and essential to daily life in every economy around the world.

A earlier overview had indicated that Nigeria had a high mobile phone penetration rate, with estimates around 85 per cent to 87 per cent in 2024.

This translates to over 200 million mobile connections, making Nigeria a leading market in Africa for mobile phone ownership and usage. While the overall penetration is high, there’s a growing trend towards smartphone adoption, with forecasts predicting over 140 million smartphone users by 2025.

According to DataReporter, a total of 150 million cellular mobile connections were active in Nigeria in early 2025, with this figure equivalent to 64.0 per cent of the total population.

However, note that some of these connections may only include services such as voice and SMS, and some may not include access to the internet.

There were 107 million individuals using the internet in Nigeria at the start of 2025, when online penetration stood at 45.4 percent. Nigeria was home to 38.7 million social media user identities in January 2025, equating to 16.4 percent of the total population.

These headline stats offer a great overview of the “state of digital” in Nigeria at the start of 2025, but in order to make sense of how digital trends and behaviours have been evolving over time, we need to dig deeper into the data.

According to the World Bank, “as of 2024, individual ownership of mobile phones reached 86 per cent of adults worldwide.

“For many people, barely an hour goes by without their using a mobile device to make a call, ext a friend, read the news, access business information, post a meme on social media, pay for something, play a game, engage with a colleague or a customer, or search for information.

“As access to and use of digitally connected technologies increase, people, businesses, and governments place an increasingly high priority on online interactions. “Digitally connected technologies have clear, well-documented benefits.”

It further highlighted that access to mobile phones and the internet was associated with reduced poverty, increased consumption, and more employment for individuals in lowand middle-income economies.

“Women also experience these benefits, as internet access enables access to flexible jobs3 and has been shown to increase female labor force participation. “Mobile phones also facilitate information sharing.

For instance, in agricultural contexts, farmers’ access to real-time prices and buyer demand data can inform their decisions on where to sell, enhancing market efficiency and reducing the distances they would otherwise travel to get the best return for their product and time.

“Internet access also helps create jobs and aids individuals and countries in exporting goods and services,” it added. The World Bank further noted that owning a mobile phone furthermore enabled financial access through mobile money and other mobile financial services.

It added that these financial accounts and services, typically offered by mobile network operators or fintech firms and accessed via networks of local agents, were associated with lower rates of poverty, increased consumption and savings,and greater resilience to economic shocks.
