My current internet provider and cell phone carrier is complete and utter garbage (In terms of price and intwrnet speed), and I can't even express how much I hate it. Their products rarely work, the internet speed in non-existent, customer support might as well be non-existent, many offers are deliberately misleading and cost a fortune, the internet speed is insanely slow.

I'm not a tech person, so I don't know how fast should a 4G mobile connection be, but I'm pretty sure that it's not the 0.15Mbps download and 0.06Mbps upload that I regularly get. That is, if 4G even works. I often have to switch to a 3G network mode because otherwise I don't have internet at all. That sometimes also doesn't work...

They also offer internet routers, which actually work well... only if you directly plug an ethernet cable into them. Otherwise the speed (Which they promised to be 100Mbps both upload and download) is around 1Mbps upload and download. That, however, is I even manage to connect to my router. My phone often just says that there is an error with the connection and I don't get any connection at all.

All of this & even more, and somehow this is the most popular cell phone carrier and internet provider in my country. Though, they do also advertise a ton.
