The growth of 5G networks doesn't mean 4G is going away. Mobile carriers will use existing 4G LTE networks to provide their customers' cell service well into the next decade. 5G networks will work with 4G — not outright replace it. The upshot is that 5G-capable cell phones will still use 4G technology.
Will 5G work on existing devices built for 3G or 4G? No. New devices will be required. This includes mobile phones and other cellular devices, such as tablets and smart watches.
Within the U.S., it's reasonable to assume that by the end of 2022 there will not be a single major carrier supporting 2G. The same fate awaits 3G. 4G LTE operates under a different scenario, and we can confidently say that 4G will be around for at least another decade.
The first 4G LTE sunset announcements are expected after 2030, which means that companies can safely invest in 4G-based IoT solutions today and for the foreseeable future.
Is it OK to buy a 4G phone in 2023? 4G phones still work on 4G LTE networks for now, but eventually they will become obsolete. Consider how long you plan to keep your phone; if you plan to keep your phone for longer than a year or so, it might be a good idea to get a phone that is 5G compatible.
Can We Use 5G SIM in 4G phone? If the question has to be answered in one word, then it is “Yes”. However, there is a catch to it. While a 5G SIM card can be used in 4G mobile, it would still be providing you with 4G networks as one of the major requirements to use the 5G technology is having a 5G-powered device.
If you don't have a 5G phone, that's fine. You can still access super-fast and extensive 4G coverage on the Telstra network until you're ready for a new 5G device. The 3G network will be decommissioned in 2024.
With 5G, you can expect higher download speeds when using mobile data, lower latency (the time it takes for a device to respond to information or an action), increased reliability and more network capacity. Basically, 5G is faster and more stable than 4G, and it's capable of connecting a lot more devices.
Chances are your mobile phone will work in Australia, however, you have a few different options if you want to stay connected during your travels - activate your international roaming (or your mobile phone's data roaming plan), connect to local wifi, or purchase an Australian SIM card and join a local network.
If you see 4G, LTE, or 4G LTE, your phone is safe and will continue to work after the 3G networks are shut down.
With faster speeds and low latency, a 5G cellular connection also provides broader signal coverage at all times.
The easy answer is no; You will not need a new SIM card for 5G. Most modern phones support both 4G and 5G, and switching to 5G is as easy as making sure your plan is 5G compatible.
Will a 5G device work with my current sim? Yes, your 5G device will be able to use a 4G sim to receive 4G/3G/2G coverage whenever it needs to. But if you want to use our 5G network, you'll need to swap to a 5G sim. Will 5G use up my data allowance quicker than 4G?
If your carrier doesn't support 5G roaming, you can get cellular data through 4G or LTE networks or obtain a local SIM card or eSIM with 5G where available.
Similar to the legendary switch from wired dialup to high-speed broadband, we will rethink what mobile data can do. That said, there is one major downside keeping 4G from being entirely replaced right now: 5G is hard to install and deploy. More transmitters are needed to cover the same area as current 4G networks.
5G up to 100 times faster than 4G
In the right conditions 5G download speeds can reach 10 gigabits per second. That's up to 100 times faster than 4G – and certainly the level of performance needed for an increasingly connected society.
4G phone will work on 5G networks, but they won't receive the enhanced 5G speed. So, if you want to experience the full potential of the next-gen network, then it is a good idea to upgrade.
No, you do not necessarily need a new SIM card for 5G. As long as your current phone model supports 5G connectivity and you're already with a provider that offers a 5G network (and plan to stick with them), you can use your existing SIM. All you have to do is switch to a 5G-enabled plan and you're good to go.
The key difference between 4G and 5G is that 5G is faster. Much faster. You should easily be able to get 4G speeds of 50Mbps in metro Australia, while 5G can go over 500Mbps.
Will a 5G SIM work on a 4G-enabled smartphone? The answer is yes. However, there is a catch to it. “While a 5G SIM card can be used in 4G mobile, it would still be providing you with 4G networks as one of the major requirements to use the 5G technology is having a 5G-powered device,” according to the Airtel FAQ.
Do I need to change my SIM card from 4G to 5G? No, 4G SIM cards are forward compatible with 5G networks. You can use 5G services with your existing 4G SIM. That said, if your mobile carrier requests you to get a 5G SIM, you should switch to a new SIM as it will improve speed and indoor coverage.
Any 3G device, whether it's a smartphone, tablet, or smartwatch, will not be able to connect to 5G networks, according to the Federal Communications Commission (FCC). What is 5G, and why should we want it?
