4G, or 4th generation of cellular communications technology, provides faster Internet speeds than 3G and 2G. This is the age of 4G mobile Internet access, as more and more subscribers migrate from 3G to 4G. Sometimes, someone asks, “How do I upgrade a 3G phone to 4G?”
4G is so much faster than 3G that it makes sense for you to upgrade from 3G. Everything is better with 4G. Technically, it is possible to upgrade a 3G phone to 4G. But you would have to be a highly skilled electronics engineer to pull it off. Let me explain.
How to upgrade a 3G phone to 4G
To upgrade a 3G phone to 4G, you would need to change a number of key components in the device. These components include: the modem and the processor. You would need to replace the 3G modem in your phone with a 4G modem. Also, if the built-in processor does not support 4G, you would need to replace that with a 4G-compatible unit too.
Chances are that the phone’s software already support 4G, but you might also have to modify one or two things in that too. So, you pretty much have to dismantle your 3G phone and have these above modifications made in order to convert it to 4G.
Unfortunately, these parts that you need to replace are not sold in your local market, and the expertise required to make those changes are not exactly available in the average phone repair shop. Where available, the total cost of such a conversion will make nonsense of things. Are you catching my drift? While it is possible to upgrade a 3G phone to 4G, it is not very pragmatic. So, what do you do?
Just Replace Your 3G Phone With A 4G Phone
If you currently own a 3G phone and want 4G Internet connectivity, the easy and simple way to go about it is to purchase a 4G phone to replace your existing device. Then sell or gift out your old 3G phone. While it is technically possible to upgrade a 3G phone to 4G, it is largely impracticable. The process is beyond what you can do, and it would be too costly.
How To Choose A 4G Phone
Before choosing a 4G phone, be sure to confirm that it supports the LTE frequency band of the 4G mobile operator that you want to use it on.
There are dozens of 4G frequency bands in use around the world by various cellular carriers. If you buy a 4G phone that does not support the 4G frequency that your operator/carrier uses, your phone will not be able to connect to that 4G network. And that would be a waste.
In addition, if you travel internationally, you should also consider what network frequency bands are supported in the countries you travel to, or intend to travel to. If you plan to use a local SIM for 4G Internet access in those countries, you will need a phone that supports available networks there. As a rule, the more bands a smartphone supports, the better.
Now you understand that though it is possible to upgrade a 3G phone to 4G, it is mostly impractical and will cost an arm and a leg. It is just best to replace your 3G phone with a 4G smartphone.
