Top 5 Tips for Reliable Smartphone Security
Nowadays, having access to data on the go is as ubiquitous as having access to water or a jacket. Yet despite the convenience of being able to log onto the Internet from your smartphone from nearly any location, there are certain risks regarding smartphone security that should concern everyone using a mobile device in public. Namely, free public Wi-Fi networks make us vulnerable to cyberattacks and data breaches.
According to TechRepublic, Android ransomware increased 137.8% from the first quarter to the second quarter of 2017. A benchmarking study of the cybersecurity practices of global companies offers insight into cyber threats. The study, called The Cybersecurity Imperative, was released by ESI ThoughtLab and WSJ Pro Cybersecurity and was sponsored by Security Industry Association (SIA), along with other partners. The study cites the following leading cyberthreats in 2018, which include malware, phishing, ransomware, viruses, and attacks from apps.
Wireless network hotspots, which are often provided by coffee shops, hotels, or airports, are significantly less secure than our private connection at home or in the office. Tech-savvy cybercriminals can easily hack into public networks and attempt to steal or even lock and extort confidential information for financial gain. One option to prevent cybertheft is to not use public Wi-Fi, however, it’s often hard to pass up. Therefore, in order to use hotspots safely, it pays to follow these simple tips to ensure you’re not an easy target for cybercriminals.
Use a Reliable Anti-Malware
Since we have already decided that it’s vital to have reliable cybersecurity protection on all our devices in order to detect, quarantine, delete and report any type of suspicious activity, it is important to continue applying this rule when we are on the go. According to cybersecurity leader Kaspersky, there were a more than 42.7 million mobile malware attacks in 2017 and malicious mobile software threats were found in more than 230 countries worldwide, making travelers especially vulnerable to cyberattacks.
Therefore, to ensure our smartphones are secure, having a reliable anti-malware is a no-brainer. The software performs routine scans of your smartphone or mobile device and updates itself with the latest security protection against cyber threats.
Always Use a Virtual Private Network (VPN)
A VPN, or Virtual Private Network, ensures you can use the Internet safely because it disguises your online identity. Rather than browsing the Internet openly by using a coffee shop, restaurant or hotel’s free Wi-Fi network, use VPN software with encryption technology to safeguard your identity and ensure you are browsing anonymously. This will protect you from those who want to spy on what you’re doing online.
A reliable VPN for smartphone automatically changes your IP address to conceal your actual location. Fundamentally, a VPN makes your smartphone or mobile device as well as the information within it undetectable and therefore inaccessible to anyone who may be on the same Wi-Fi network as you. Not only will hackers not be able to pilfer your data, but they also won’t be able to infect your device with ransomware or other malware.
Be Careful Where You Connect
It is crucial to be sure you’re joining a secure Wi-Fi connection. Often, we connect simply by instinct. For example, if a network is called HotelFreeWiFi, we may innocently assume that it is the hotel’s network, yet it can often be a calculated “man-in-the-middle” attack employed by hackers to fool users into logging in in order to steal their information.
According to the Pew Research Center, 54% of internet users use public Wi-Fi networks, and many perform sensitive activities such as online shopping (21%) or online banking (20%) in public. Therefore, when logging in on the go, ensure your Wi-Fi network is secure and not a rogue network. Double check with the barista or receptionist to find out the actual name of the coffee shop or hotel Wi-Fi network.
Remain Alert On-The-Go
It is also important to be selective about what you’re looking at on your smartphone while in public. Using free Wi-Fi for reading the news or streaming music is one thing but be careful when you’re performing sensitive tasks like reading your email, banking, or online shopping. When performing these activities, you find a secured connection in an Internet browser that has a padlock or the letters HTTPS or SSL in the URL window, rather than HTTP.
Also, for added security, try to perform sensitive operations from your own personal hotspot by using your data plan for things like email, shopping or banking.
Additional Tips
It is also important to back-up your important information and other data at least once a week just in case you lose your smartphone, or your mobile device is stolen. A great solution is to use cloud services and local back-up, like a USB flash drive or external hard drive.
Also, use a strong password, which is at least 7 characters long, has a combination of letters, numbers and symbols, and combines upper and lower cases. Experts say it can also be effective to use a passphrase, such as a line from your favorite song, like “royaltyinsidemydna,” from Kendrick Lamar’s DNA.
Additionally, when possible, choose a two-step verification that requires not just a password to log in, but also a one-time code that is sent to your smartphone in order to confirm it’s actually you using the device. If your smartphone is not set up to do this automatically, download the latest free software updates for the Windows or Mac operating system on your device.
Users should be concerned about smartphone security even if privacy isn’t a top priority for them. A VPN for smartphone or tablet, which unlike your home computer will be using public Wi-Fi access occasionally, either in a coffee shop, airport, or hotel, ensures your data is protected. Public hotspots are not particularly trustworthy, and those that don’t require a password are even more vulnerable to attack. A mobile VPN isn’t just smart, it’s vital.

Nigeria has emerged as Africa’s highest-ranked country in the latest Global Index on Responsible AI (GIRAI), climbing 42 places globally in just two years.
Nigeria rose from 80th globally in 2024 to 38th in the world with a score of 45.93.
The GIRIA ranking boosts Nigeria’s appeal as a destination for AI talent, innovation and investment.
According to the Cape Town-based independent research and policy think tank, the ranking is one of the world’s most comprehensive assessments of responsible AI. It evaluates 135 countries across five pillars: inclusion and diversity, ethics and sustainability, labour and skills, trust and safety, and AI use in public services.
Despite that rapid adoption, the report found that public governance capacity remains weak. Average GIRAI scores stand at only about 35 out of 100 globally, while evidence of implementation exists in just 55 per cent of countries with responsible AI frameworks, dropping to 45% across the Global South.
Nigeria’s rise reflects deliberate policy efforts to strengthen its AI ecosystem.
According to the Minister of Communications, Innovation and Digital Economy, Mr Bosun Tijani, the government has accelerated work on its National Artificial Intelligence Strategy (NAIS), expanded digital public infrastructure, invested in digital skills, developed governance frameworks for emerging technologies, and strengthened international partnerships to ensure AI is deployed responsibly.
“This recognition is a testament to Nigeria’s deliberate efforts to build an AI ecosystem that is inclusive, responsible, and aligned with our development priorities,” he said.
“We believe that Africa must not only participate in the AI revolution but also contribute meaningfully to shaping how these technologies are governed and deployed globally.
“Our focus remains on creating the infrastructure, talent, and policy environment that will enable AI to deliver real value for our people and support President Bola Tinubu’s vision of building a $1 trillion economy,” he added.
The report identified Nigeria as a global “Bright Spot” for combining AI skills development with safeguards for children and vulnerable groups.
The index noted that Nigeria is among the few African countries that have attempted to simultaneously prepare citizens for an AI-driven future while strengthening protections against the risks posed by emerging technologies.
It highlighted the National Artificial Intelligence Strategy, which mandates AI literacy programmes, teacher training and broader capacity-building initiatives across the country.
The report also cited the Federal Government’s flagship 3 Million Technical Talent (3MTT) programme for delivering structured AI and machine learning training through a hybrid model designed to reach young people nationwide.
In terms of regulation, GIRAI recognised the Nigeria Data Protection Act and the General Application and Implementation Directive (GAID) 2025 for introducing enhanced safeguards for children’s personal data, including parental consent requirements and restrictions on decisions based solely on automated processing.
The report said these initiatives position Nigeria as an example of how governments can pursue AI adoption without overlooking digital rights and citizen protection.

The need for accessible, affordable and locally relevant Artificial Intelligence (AI) to drive Africa’s digital future has been emphasised by the Managing Director of ipNX, Mr Ejovi Aror.
Mr Aror, whose paper was presented by the company’s Director of Strategic Business Initiatives, Mr Olusola Teniola, at the West Africa Telecoms Infrastructure Summit and Exhibition (WATISE) on June 18, 2028, said AI is not a new concept, but has been in existence since 1955 and is an integral part of today’s digital ecosystem, with intelligent algorithms already embedded in so-called ‘traditional’ telecommunications networks and services.
At the event held in Lagos, Mr Aror, in his paper titled Next-G Telecoms Infrastructure and Ethical AI in Networking Management, stated that, “Artificial Intelligence already shapes how networks are managed, optimised, and secured. The conversation is not about whether AI will transform telecommunications, but how we can ensure that its benefits are responsibly deployed.”
He emphasised that while Africa may not have played a leading role during the earliest stages of AI development, the continent still has a significant opportunity to shape the next phase of innovation by developing technologies that address local challenges and realities.
“Africa does not need to be solely a consumer of AI technologies developed elsewhere. There is a unique opportunity to build solutions that reflect our local contexts, address our specific needs, and create value for our economies and communities,” he stated.
The presentation also highlighted the importance of ethical considerations in AI deployment, particularly as intelligent systems become increasingly involved in network operations, service delivery, decision-making processes, and customer interactions.
Mr Aror stressed that the development of AI must be guided by principles of transparency, accountability, privacy, and inclusivity to ensure that innovation delivers meaningful benefits to society.
He further noted that the success of AI across Africa will depend on continued investment in digital infrastructure, including broadband connectivity, data centres, cloud platforms, and reliable telecommunications networks capable of supporting advanced digital services.
The discussions at WATISE 2026 reinforced the strategic importance of the telecommunications industry as the foundation of Nigeria’s digital economy. While stakeholders highlighted the role of telecom infrastructure in enabling innovation across various sectors, participants underscored the need for improved digital literacy, public awareness, and responsible use of emerging technologies.
ipNX was recognised at the event as the Best Customer-centric Telecoms Operator. As Nigeria’s leading technology and connectivity provider, the brand remains committed to advancing the infrastructure, innovation, and collaborative partnerships required to unlock the full potential of AI and support Africa’s digital transformation.

Latest data from the Nigerian Communications Commission (NCC) has revealed that Nigeria’s teledensity rose to 86.73 per cent in April 2026, up from 85.67 per cent recorded in March, as active mobile subscriptions increased to 188.01 million, reflecting sustained expansion in access to telecommunications services across the country.
Teledensity refers to the number of active telephone connections (mobile or fixed-line) per 100 people in a specific geographic area.
This growth was driven largely by increasing demand for mobile voice and data services, as more Nigerians integrated digital communication into their daily lives for work, education, commerce, and social interaction.
The NCC’s report provided a detailed breakdown of operator performance, with MTN Nigeria retaining its dominant position as the largest mobile network operator. MTN recorded 96,391,419 active subscribers, accounting for more than half of the country’s total mobile subscriptions.
Airtel Nigeria followed with 64,670,018 subscribers, maintaining its stronghold as the second-largest provider. Globacom, the indigenous operator, recorded 23,178,597 subscribers, while 9mobile had 3,538,021 active subscribers during the period.
The competitive dynamics among these operators continued to shape the market, with each vying for greater market share through innovative data plans, network expansion, and enhanced customer service offerings.
The commission’s data also highlighted a significant technological shift in network usage, as consumers increasingly migrated to faster broadband technologies. Fourth-generation technology remained the dominant mobile network platform, accounting for 54.41 per cent of total network connections in April, up from 53.76 per cent in March.
This steady increase underscored the growing preference for high-speed internet capable of supporting video streaming, online gaming, remote work, and digital learning.
Similarly, fifth-generation technology continued its steady growth trajectory, with its market share rising from 4.20 per cent in March to 4.34 per cent in April. The gradual rollout of 5G infrastructure by operators in major cities and urban centres has begun to yield tangible results, offering lower latency and faster download speeds that are expected to drive innovation in sectors such as healthcare, agriculture, and manufacturing.
In contrast, the share of second-generation subscriptions declined to 35.93 per cent from 36.74 per cent, reflecting a gradual but clear shift away from legacy networks to higher-speed broadband services.
The third-generation segment remained relatively stable, accounting for 5.32 per cent of total connections compared with 5.30 per cent recorded in March.
This stability suggested that while 2G users were upgrading, a core group of subscribers still relied on 3G networks, particularly in rural and underserved areas where more advanced infrastructure was not yet fully deployed.
The report further showed that of the total subscriptions, 154,347,260 were on mobile GSM networks, while fixed wired internet subscriptions stood at 156,662. Voice over Internet Protocol services accounted for 220,166 subscriptions, indicating a niche but growing interest in internet-based voice communication alternatives.
The NCC also reported significant growth in broadband subscriptions, which increased to 120,684,625 in April from 117,710,397 in March.
Consequently, broadband penetration improved to 55.67 per cent from 54.30 per cent recorded in the previous month. The commission attributed this increase to continued investment in broadband infrastructure by both private operators and government-backed initiatives, as well as the growing adoption of high-speed internet services by households and businesses seeking to leverage digital tools for productivity and connectivity.
Despite the encouraging growth in broadband subscriptions, total internet data consumption declined slightly during the month. According to the report, internet usage fell marginally to 1,414,848.70 terabytes from 1,422,764.54 terabytes recorded in March.
The report suggested that while more Nigerians were gaining internet access, overall data consumption remained relatively stable, possibly due to factors such as price sensitivity, data bundle optimisation, and the varying intensity of usage across different user segments.
This moderation in consumption did not detract from the broader positive trend of expanding connectivity and digital inclusion. The NCC noted that the telecommunications sector continued to play a critical role in the nation’s economy, contributing 9.19 per cent to Nigeria’s Gross Domestic Product (GDP) in the first quarter of 2026.
This contribution underscored the sector’s transformation from a mere utility provider to a foundational pillar of economic activity, enabling everything from fintech transactions and e-commerce to remote governance and digital entertainment.
The commission added that sustained investment in broadband infrastructure, wider deployment of 5G networks, and improved quality of service would further accelerate digital inclusion, spur innovation across industries, and drive inclusive economic growth in the country.
It also emphasised the need for continued policy support, regulatory stability, and collaborative efforts between the public and private sectors to bridge the remaining digital divide and ensure that the benefits of connectivity reach every corner of the nation.
