It depends on the coverage of the specific budget broadband deal you’re talking about. In addition, home internet plans’ internet speeds and data capacity vary from one company to another. Hence, it’s difficult to determine if the specific budge broadband deal you’re talking about will work for you.
But what you can do is to determine your internet consumption patterns (work, gaming, streaming content, uploading, downloading, voice and video calls and meetings, etc.), and that will somehow give you an estimate of how much speed and data usage you’ll be needing each month.
As to the budget-friendliness of the deal, you can check out different websites of service providers and check their budget plans and their respective inclusions (data, maximum internet speed, and even the typical evening speed) and compare the budget plans of the service providers to see who offers the best rates.
