5 Things Must-Consider Before Selling Your Phone

A phone may be the rage, but give it a year or two, it loses its lustre; new models flood the market and you start to itch for an upgrade.
Of course, you are not just going to toss your old phone in the drawer labelled “old stuff”! Trading it in can help with the cost of an upgrade and selling it online can give you some major cash.
Before you sell off your old smartphone in favour of something shiny and new, though, it is important that you take some precautionary measures.
You need to prep your cast-off device properly by deleting all the precious digital entertainment and media and the wealth of sensitive personal data that you do not want disappearing or falling into the wrong hands.
To avoid potential trouble, Jumia Travel offers these few steps to take, to make sure that your information is really cleared off your phone before you get rid of it.
Backup Apps and Data
First thing to do is make a backup of your data and personal information including your contacts, messages, calendar entries, app data, documents, photos etc.
You can do this either by plugging the phone to your laptop and syncing the data, or you can upload it to Cloud storage service such as Dropbox, Flickr, Microsoft OneDrive and Google Drive if you need online based approach.
Encrypt Your Phone
You may decide to delete your data after you back them up, but to ensure all of your data is gone, you may need to take a step further and encrypt the phone. That way, you will ensure the data will not be able to be recovered by anyone.
To do this, plug your phone in; go to your “Settings” page, then Security, next Screen Lock or Encrypt Device, depending on your smartphone.
You will be prompted to create a unique password or lock PIN, and that allows you to perform an encryption. The process can take about an hour, and once you encrypt your phone, there is no going back. After the device is encrypted, now you can then perform a factory data reset.
Restore to factory setting
The easiest way to erase every single data on your phone is by initiating a factory reset. Restoring your phone to factory setting erases all of the data and takes your phone back to the settings that were on it when initially purchased.
This usually only works with smartphones and basically entails going to Settings, then Backup & reset, then Factory data reset. The factory setting is usually a permanent form of erasing as you cannot reverse a factory reset.
Get Rid of your SIM or MicroSD cards
After you have cleared all data, the next last step in making sure everything is gone is physically removing the memory card and the SIM cards.
Most people forget to take these out, with the hope that it is harmless after a factory reset, but contacts and call logs can be stored on your SIM or microSD cards.
Clean The hardcover of the Phone
To get a good price for the phone, you certainly do not want to present it looking unkempt. After clearing out the data and taking out the memory cards, take some time to thoroughly clean the phone’s cover so that it looks as new as possible.
Remove the protective screen and casing, and get the dirt out from underneath.
Further, put it in a casing and if possible, include the stock accessories and extras that originally came with it.

Study Shows Blocks in Telegram are Pushing the Underground Out

Modern messengers, such as WhatsApp, Telegram, Signal and others, are often used for illicit purposes. Kaspersky Digital Footprint Intelligence has conducted an in-depth monitoring of over 800 blocked cybercriminal Telegram channels between 2021 and 2024.

While a range of illegal activities continues to be hosted on the platform, its environment has become noticeably more challenging for sustained underground operations.
Telegram’s bot framework and other built-in features make for a low-effort ecosystem for the underworld.
A single bot can simultaneously manage queries, process cryptocurrency payments, and instantly deliver stolen bank cards, info-stealer logs, phishing kits, or DDoS attacks to hundreds of buyers per day, often without operator involvement.
Unlimited, non-expiring file storage eliminates the need for external hosting when distributing multi-gigabyte database dumps or stolen corporate documents. This frictionless automation naturally favours high-volume, low-price, low-skill offerings, such as leaked bank cards or other data, hosting malware, etc.
High-value, trust-dependent deals (for instance, zero-day vulnerability information) still remain on reputation-gated dark-web forums.
Kaspersky researchers found two clear trends related to illegal activities on Telegram. The average lifespan of shadow channels has increased, with the proportion of channels surviving over nine months more than tripling in 2023-2024 compared to 2021–2022. At the same time, Telegram’s blocking activity has risen significantly.
Monthly takedown figures recorded since October 2024 – even at their lowest – are comparable to the peak levels seen throughout 2023, and the overall pace continued to accelerate in 2025. This impedes malicious activities.
Other disadvantages of Telegram for cybercriminals include the lack of default end-to-end (E2E) encryption for chats, the inability to use their own servers for communication (due to the messenger’s centralised infrastructure), and closed server-side code, which makes it impossible to verify its functionality.
As a result, several established underground communities, including the nearly 9,000-member BFRepo group and the Angel Drainer malware-as-a-service operation, have already begun shifting primary activity to other platforms or proprietary messengers, citing repeated disruptions of their activities on Telegram.
“Fraudsters find Telegram a convenient tool for many malicious activities, but the risk-reward balance is clearly shifting. Channels are managing to stay online longer than a couple of years ago, yet the dramatically higher volume of blocks means operators can no longer count on long-term stability.
“When a storefront or service disappears overnight – and sometimes reappears only to be removed again weeks later – building a reliable business becomes much harder. We’re starting to see the early stages of migration as a direct consequence,” comments Vladislav Belousov, Digital Footprint Analyst at Kaspersky.

Galaxy Backbone Marks Two Decades of Powering Nigeria’s Digital Evolution

Galaxy Backbone Limited (GBB), the Federal Government’s leading ICT infrastructure and shared services provider, will mark its 20th anniversary in June 2026 with a grand celebration that reflects two decades of innovation, resilience, and national impact.

Since its inception in 2006, Galaxy Backbone has been at the heart of Nigeria’s digital transformation journey; building the technological foundation that supports modern government operations and public service delivery. What began as a bold vision to connect government has grown into a critical national platform that drives efficiency, transparency, collaboration and innovation across the public sector.
Over the last 20 years, GBB has helped redefine how government works. By providing secure connectivity, enterprise-grade data centre services, cloud platforms, and digital collaboration tools, Galaxy Backbone has enabled Ministries, Departments and Agencies (MDAs) to move from fragmented, paper-based processes to more integrated, technology-driven systems.
This transformation has improved government-to-government coordination, strengthened engagement with businesses, and enhanced the delivery of services to citizens. Today, the digital infrastructure powered by Galaxy Backbone supports thousands of government users, hundreds of institutions, and critical national platforms that Nigerians rely on daily.
A key part of this journey has been the Federal Government of Nigeria’s investment, managed by GBB in robust national infrastructure, high-capacity and world class data centres, fibre-optic connectivity across multiple states, secure hosting services, and shared platforms that have helped government operate more efficiently and responsively. These contributions have played a pivotal role in Nigeria’s progress toward a more digital, agile and citizen-centered public service.
Galaxy Backbone’s impact has earned both national and global recognition. In 2025, the organisation was ranked first overall in the Federal Government Website Performance Scorecard, reflecting its commitment to excellence in digital service delivery. Internationally, GBB, a couple of years ago, received the prestigious United Nations Public Service Award, a testament to its leadership in promoting a whole-of-government approach to digital transformation.
As GBB celebrates two decades of service, this milestone is more than an organisational anniversary; it is a celebration of Nigeria’s digital evolution. It is an opportunity to appreciate how collaboration between government, industry partners, technology providers, and dedicated public servants has helped build a stronger, more connected nation.
The June 2026 anniversary celebration will bring together stakeholders from across the public and private sectors to reflect on the journey so far, acknowledge the partnerships that have shaped this success, and chart an ambitious course for the future. It will highlight how collective effort, shared vision, and innovation have positioned Galaxy Backbone as a strategic national asset.
Looking ahead, Galaxy Backbone remains committed to deepening digital transformation across the country; expanding infrastructure, strengthening cybersecurity, enhancing service delivery, and supporting the Federal Government’s drive for a smarter, more efficient and digitally empowered Nigeria.
At 20 years, Galaxy Backbone stands proud of its past, confident in its present, and inspired by the limitless possibilities ahead.
