What is Internet Data Usage?
Internet data is a service provided by telecom operators like MTN, Airtel, Glo, and 9mobile that allows users to access the internet. When you browse websites, stream videos, or use social media apps on your phone, you're consuming internet data. The amount of data used depends on your online activities – watching a YouTube video uses more data than sending a WhatsApp message, for example.
The speed of your internet connection and the types of activities you can perform online largely depend on the network technology being used. These technologies are classified into "Generations" that indicate their age and capabilities.
Understanding Network Generations
2G (Second Generation)
2G is the oldest widely available mobile network technology still in use in Nigeria. It uses circuit-switched technology and provides relatively low-speed internet access through GPRS (General Packet Radio Service) or EDGE (Enhanced Data rates for GSM Evolution).
With 2G, you can:
Send text messages
Make voice calls
Browse simple websites (though very slowly)
Use basic WhatsApp text messaging
2G is still common in rural areas of Nigeria where newer network infrastructure hasn't been deployed. If you've ever noticed your phone showing "E" instead of 3G or 4G, you were on an EDGE (2G) connection.
3G (Third Generation)
3G uses both packet and circuit-switched technology, operating in HSPA (High Speed Packet Access) or HSPA+ modes. It provides significantly faster internet speeds than 2G.
With 3G, you can:
Browse websites comfortably
Use social media apps
Stream music
Watch videos at lower resolutions
Make video calls (though quality may vary)
3G is widely available across Nigeria's urban and semi-urban areas. It's suitable for most everyday internet activities, though it may struggle with high-definition video streaming or online gaming.
4G (Fourth Generation)
4G is a packet-switched technology that operates in LTE (Long Term Evolution) or LTE-A (LTE Advanced) modes. It offers significantly faster speeds than 3G, making it suitable for data-intensive activities.
With 4G, you can:
Stream high-definition videos smoothly
Make clear video calls
Download large files quickly
Play online games with minimal lag
Use multiple data-intensive apps simultaneously
4G coverage has expanded significantly in Nigeria in recent years, with most major cities and towns now having access. For example, in Lagos, Abuja, Port Harcourt, and Kano, 4G coverage is widely available from all major providers.
5G (Fifth Generation)
5G is the newest generation of mobile network technology, designed to increase speed, reduce latency (delay), and improve the flexibility of wireless services. It represents a significant leap forward from 4G.
With 5G, you can:
Stream 4K videos without buffering
Download very large files in seconds
Experience virtual reality and augmented reality applications
Connect multiple devices without speed degradation
Enjoy near-instantaneous response times for applications
In Nigeria, 5G deployment is still in its early stages. MTN Nigeria launched the country's first commercial 5G network in September 2022, initially available in Lagos, Abuja, Port Harcourt, Ibadan, Kano, Owerri, and Maiduguri. Airtel has also begun rolling out 5G services in select locations.
What does G stand for?
As explained above, “G” stands for “GENERATION”. When you connect to the internet, the speed of your internet access is dependent upon the signal strength and the access technology. The technology is shown in alphabets like 2G, 3G, 4G 5G etc. right next to the signal bar on your mobile phone’s home screen.
Does the usage of 2G, 3G, 4G or 5G have any impact on data exhaustion? Can this also lead to fast data depletion?
The higher the Generation, the higher the speed, and consequently the better your browsing experience i.e. browsing on a lower Generation is slower but would still consume the same quantity of data (bytes/MB/GB). In addition, the device resolution has a great impact on the data consumption. i.e Highest video quality consumes more.

Backward Compatibility of Network Technologies
An important feature of these network technologies is backward compatibility. This means newer phones are designed to work with older network generations. For example, a 5G-capable phone can still connect to 4G, 3G, or even 2G networks when 5G isn't available.
This is particularly important in Nigeria, where network coverage varies significantly between urban and rural areas. When you travel from Lagos to a village in Oyo State, for instance, your phone might switch from 4G to 3G or even 2G as you move away from urban centers.
Your phone typically displays the current network generation you're connected to in the status bar (G, E, 3G, 4G/LTE, or 5G).
Practical Implications for Nigerian Users
Understanding these different network generations can help you make better decisions about your internet usage:
Data Plans: 4G and 5G consume data faster because they allow you to access more content more quickly. If you're on a limited data plan, be mindful when connected to faster networks.
Device Selection: When buying a new phone in Nigeria, consider the network capabilities. A 5G phone might be future-proof, but if you live in an area with only 3G coverage, you won't benefit from the 5G capabilities yet.
Network Provider: Different providers have different coverage strengths. MTN might have better 4G coverage in one area, while Airtel might be stronger in another.
For example, if you live in Yaba, Lagos, and frequently stream videos or attend online classes, a 4G connection would be essential. However, if you're in a rural area in Benue State where only 2G or 3G is available, you might need to adjust your internet usage accordingly, perhaps downloading content when you're in areas with better connectivity.
