5G won't fully replace 4G anytime soon; instead, they'll coexist for at least another decade, with 4G LTE expected to remain functional and essential well into the 2030s and possibly the 2040s, acting as a crucial foundation, especially in less dense areas, as 5G rollout continues to expand. The transition involves a gradual shift, not an abrupt replacement, with operators phasing out older networks like 3G to repurpose spectrum for 4G and 5G, creating a hybrid network for years.
5G isn't replacing 4G any time soon. In fact, they will coexist and work together. 5G-capable phones can actually use both 4G and 5G technology.
(But if you were to build a brand new network today, you would likely use 5G only.) They won't even starting thinking about 4G obsolescence until 6G is established, in the early 2030s.
5G may be the new standard of wireless internet, but 4G still has its uses, especially if you need online backup. 4G technology has been available for 15 years, and experts consider 2030 to be the year we'll begin phasing it out.
In theory, 5G delivers an average speed of 10 Gbps, which is more than 100 times faster than current 4G technology. Actual average 5G download speeds are currently being measured between 1.4 and 14 times faster than 4G.
Disadvantages of 5G Technology:
Network speed: 6G speed is expected to be 50 times faster than 5G with 6G anticipated to reach rates of up to 1 Tbps compared to theoretical speeds of up to 20 Gbps per second in 5G. Enhanced reliability and wider network coverage.
Factors such as network congestion, signal strength and coverage, device limitations, background apps, data throttling, and SIM card issues all play a role in your 4G experience.
2G, understood as GSM and CdmaOne, has been superseded by newer technologies such as 3G (UMTS / CDMA2000), 4G (LTE / WiMAX) and 5G (5G NR). However, 2G networks were still available as of 2023 in most parts of the world, while notably excluding the majority of carriers in North America, East Asia, and Australia.
A modern 4G phone in 2025 can still provide an excellent mobile experience for most daily tasks. You can expect: Reliable internet browsing and social media use. Smooth video streaming in HD.
4G LTE operates under a different scenario, and we can confidently say that 4G will be around for at least another decade. And because 4G LTE has plenty of speed and reasonably low latency for most applications, it is an excellent choice for IoT applications today.
5G can deliver faster speeds, but only in well-covered areas. NBN provides wider coverage across Australia.
While 2G and 3G networks are now being phased out globally, both 4G and 5G networks continue to coexist. If a 5G network isn't available, the phone will automatically connect to a 4G network, or possibly an earlier network service, depending on availability.
Commercial deployment of 6G is anticipated in the early 2030s, following standardization milestones later in the 2020s.
Yes, cellular networks like 5G will always consume more battery than Wi-Fi. The reason is simple: the further you are from a 5G tower, the harder your phone has to work to maintain a connection.
If 5G coverage is strong, you'll enjoy the benefits of ultra-fast speeds and low latency. If the 5G connection falters or becomes temporarily unavailable, the modem will seamlessly switch over to the 4G network**, helping maintain a stable internet connection without you needing to do anything.
None of the major carriers in the US have switched off their 4G LTE networks yet. Only T-Mobile USA has announced a planned 4G LTE final shutdown date, and that is not until 2035.
If your mobile was identified as being affected this way by the 3G shutdown on or before 1 November 2024, your services may have been disconnected between 28 October 2024 and 1 November 2024.
Users will need 4G or 5G-compatible devices to continue enjoying uninterrupted mobile services. As 2025 approaches, the retirement of 2G and 3G networks marks a critical juncture in the global transition to modern telecommunications.
An older mobile phone could also lead to signal issues. Carriers often add frequencies to their networks, and your phone may not connect to the newest frequency. As technology standards for cellular networks improve, older iPhone and Android phones become outdated.
Wi-Fi signals have a limited range, and the farther you are from the router, the weaker the signal becomes. This can result in slower internet speeds, disconnections, and even complete loss of connection. In contrast, 4G cellular signals are not affected by obstacles in the same way as Wi-Fi signals.
Toggling airplane mode works in much the same way as restarting your phone. When you activate and then deactivate airplane mode, you are instructing the mobile device to restart the network search from the beginning, helping resolve the issue of slow internet.
To date, China has implemented its 5G wireless technology in 52 of the country's 97 main economic categories. Its implementation is now being expanded to a larger scale, such as to the mining, port and electricity sectors.
How much faster could 6G be than 5G? In November 2024, New Scientist reported that researchers at University College London had sent data at 938 gigabits per second across a lab-built 6G network. That's more than 9000 times the average speed of a current 5G phone connection.
At 6g I can't even lift my hand off my leg, let alone press buttons on the watch. James Bond never had this trouble. At 12g he still managed to get his watch to shoot a dart to disable a centrifuge. I can feel the blood leaching from my head, my face sagging.
