3G vs 4G
3G internet stands for “third generation” and is a standard used for mobile telecommunications technology. This is a feature that most phones and devices have built into them enabling broad-band speed internet accessed through the same radio towers that provide your phone service . There are lots of different varieties of 3G and some are much faster than the others, they all need to offers a minimum consistent internet speeds.
4G is the forth generation and has potential to be much faster than 3G. However this potential is not always maximized as there is no requirements or standards needed to call a network 4G. This means, depending on the location and the operator, there are 3G networks that are faster than 4G networks.
Depending on your mobile plan you will have a certain amount of 3G or 4G data will or will not be included. The best way to know if you have any 3G data included in your plan is to directly contact your provider.
When to choose 3G or 4G ?
If you have to buy a new phone should you choose a 4G compatible phone or is 3G good enough? 4G is is the future of mobile data connections. Although it does not solve any call related issues if you use your phone for streaming videos or anything else that involves high data transmission 4G may be the better option for you. If you use your smart phone if primarily for it’s phone features than 3G is all you would need.
Data roaming
Phone plans include a certain zone/area in which their offered services apply. Outside of this area connection to networks will be done through data roaming. This takes into account internet access, receiving photos, app notifications… Mobile operators can charge you extra for using data roaming. It is good practice to leave it off by default unless it is needed.
