Choosing an ISP affects your daily life, work, and entertainment. Don't just follow flashy ads; look for facts.\n\nThe most important factor is the available technology. Fiber (FTTH) is king, followed by VDSL, then old ADSL. Ask neighbors in your building about their experience, as quality varies by local infrastructure.\n\nCheck the "Fair Usage Policy"; some companies offer high speeds that drop sharply after a certain data limit. Don't forget technical support quality. Price is important, but stability is the priority in the internet world.
