Will 4G be discontinued?
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.
When Will 4G Be Phased Out? 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.
Verizon is sending free 4G flip phones to customers who are still using the company's older 3G network, which it plans to retire by the end of 2022, according to the company's support page. Verizon's issuing the devices to people who haven't yet upgraded to a 4G LTE phone.
First of all At&t '4g' is 3g, and is shutting down now through February 2022. You need a phone that is voice over LTE capable on AT&T.
But since phones are not modular by nature, in reality, it is impossible to upgrade a 4G phone to support 5G. You'll be better served upgrading to a newer phone that natively supports the faster 5G networks.
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.
The 5G phones currently on the market are "backward compatible," meaning that they are capable of functioning on earlier-generation networks outside of 5G coverage areas. Will a 3G or 4G phone continue to work? 4G devices will continue to work.
T-Mobile announced that it finished shutting down Sprint's 3G CDMA network as of March 31, 2022 and Sprint's 4G LTE network as of June 30, 2022.
So what's the difference between 4G and LTE, and is 4G or LTE better? In short, 4G offers a much faster speed, more stability and access to a larger variety of online activities. LTE is a half-point between 3G and 4G, so its performance suffers compared to the fourth generation.
On Android smartphones, go to settings > Network settings > mobile network. It should give you a dropdown menu of mobile standards such as 2G, 3G or LTE (4G). If you don't see 4G or LTE, then your smartphone doesn't support the standard.
How long has 4G cell phone technology been available?
Since its adoption in 2009, 4G has just about reached its capacity in terms of data transferring speeds. With new technologies being introduced at a rapid pace, the world needs a faster network.
AT&T is slated to pull the plug Tuesday on its “third generation” telecommunications network as it shifts bandwidth resources toward the expansion of far more advanced 5G technology. That means people with 3G and some 4G devices — namely, those that don't support VoLTE (Voice over LTE) — will no longer get service.
AT&T has made the decision to sunset their 3G/4G network effective February 22, 2022. In order to avoid service disruption, any OmniMetrix monitoring device that utilizes this technology will need to be replaced prior to the sunset date that AT&T has provided.
Now we can revisit the earlier question: Do you need a new sim card to access the 5G network? The short answer is no, you do not need a new sim card to upgrade to 5G if your current sim card is working on 4G.
Verify that there is 5G coverage where you are. Yes, 5G is everywhere, but there are still huge gaps in the network which means you won't always have coverage. Your 5G capable phone will always find a signal and connect if 5G. If it isn't available, your phone will revert back to LTE or 4G.
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.
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.
No one has announced 4G/LTE sunset dates yet. It's likely to be around until at least 2030. And usually, once sunset dates are announced, they slip a year or two. That's just what happened in the USA with 3G, which was supposed to vanish at the end of 2020, but didn't really get phased out until the mid/late 2022.
Unfortunately, the ability to access the 4G network depends on your phone's capability. So, if you have a 3G phone, you won't have access to the 4G network.
After December 31st, 2022, says Verizon, if you are a Big Red customer still using a device that is 3G (CDMA) or 4G that does not support HD Voice (Non-VoLTE), the device will no longer make/receive calls, send/receive text messages, or use data services.
What phones will not work after 5G?
Among iPhones, only iPhone 12 and the later models like iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max support 5G. So, if your iPhone is older than iPhone 12, it won't support 5G. All of these models are built with the Apple A14 Bionic processor.
If you own an older cellphone with 3G, be aware that in 2022, some of your electronics will stop working because of a 5G upgrade. If you own an older cellphone with 3G or a Kindle, be aware that in 2022 some of your electronics will stop working because of a 5G upgrade.
You're experiencing 4G congestion. It's also possible that you are experiencing slow 4G downloads because of congestion on the mobile broadband network, rather than the network suffering an outage. When too many in your area people use 4G at once, this can decrease your download and upload speeds in severe cases.
"As a result, many older cellphones will be unable to make or receive calls and texts, including calls to 911, or use data services. This will affect 3G mobile phones and certain older 4G mobile phones that do not support Voice over LTE (VoLTE or HD Voice)," the FCC said.
Some tracfones, flip phones, Jitterbugs and even older-style smartphones will no longer be able to make calls once the networks are taken down. Most of these phones, which are sometimes called “third generation” phones were launched nearly 20 years ago and will no longer work with most of the carriers in 2022.
Tap on “More” Tap on “Mobile network” Tap on “Preferred network type”
If 4G or LTE is available from your provider, you can switch to a 4G network in your cellular or mobile settings. If you don't see the 4G or LTE option on your Android and are sure your phone is compatible, dial #*#4636#*#* to enable the feature. Some carriers do not allow you to change your network type.
Depending on the wireless carrier, 4G can indicate either a UMTS or LTE connection. If your carrier doesn't support VoLTE and is a CDMA carrier, you'll only see an option to Enable LTE. This allows cellular-data use over the LTE network when available. Learn more about cellular data networks.
Are other cellular devices affected? Yes. Any device with a 3G cellular connection or a Sprint 4G LTE connection will be affected by the 2022 3G Shutdown. For example, many automotive-connected devices may be affected, including older OnStar systems and certain remote start systems.
That all remains possible through 4G LTE, 5G, and Wi-Fi networks. With 3G turned off, the iPhone 3GS, for example, won't be able to make calls or text messages, but can still connect to Wi-Fi to access internet-based applications.
What is the oldest phone that supports 4G?
Any iPhone since the iPhone 6 will support 4G/LTE (VoLTE). That is, any iPhone made since 2014.
A 4GB data plan will allow you to browse the internet for around 48 hours, to stream 800 songs or to watch 8 hours of standard-definition video. Nowadays, the key difference between mobile phone price plans is how many gigabytes of data it comes with.
2010 – First LTE (4G) smartphone
The Samsung SCH-R900, the first 4G smartphone, was also released by Samsung in the same year. In 2010, several further innovative features hit the market.
A local network outage can be one of the many reasons that AT&T's Internet may be slow or unreliable. Common causes of a local network outage include power outages, equipment malfunctions, and software issues. If there is an issue with the AT&T infrastructure in your area, this could also lead to service disruptions.
What phones are affected by the 3G shutdown? For Apple, any phone model older than iPhone 6 will stop working on the 3G network. Whereas for Samsung devices any model before Galaxy S4s will stop working on the AT&T 3G network.
AT&T will shut down its 3G network by February 2022 and is offering customers a free phone if their older one won't work after the shutdown.
LTE+ has less buffering and faster downloads than regular 4G LTE. Data rates are higher with peak download speed of 3 Gbps and Uploads at 1.5 Gbps. That is 2-3 times faster than regular LTE speeds. The network can use what is called carrier aggregation.
In 2011, it was reported that AT&T would upgrade its network to HSPA+ throughout the year, which it would market as offering 4G-grade speeds. On September 18, 2011, AT&T first launched LTE service in 5 U.S. metropolitan areas, with plans for serving 15 markets by the end of the year.
So in other words, LTE is 4G. The HSPA+ that ATT calls 4G is not really 4G.

Can I change my 4G SIM to 5G with same number?
The simple answer is yes. You don't need to buy a new 5G SIM card for a new 5G smartphone. You can easily use your old 4G SIM card on your latest 5G phone. If your SIM card works well with 4G/LTE networks, then it will also work with 5G whenever it goes live in your area.
Multiple studies suggest that 4G is going to be a major part of India till 2027 at least. Only after 2027 will we see 4G slowly phasing out.
