Who's getting good experience on the unlimited off peak? In my area (Bez valley, JHB east) the signal is there and 4g but no through put. When you switch off and on, it works for a couple of seconds but then the speed slowly deteriorates and eventually back to zero, rendering it unusable. This especially when trying to stream videos or downloading updates. It doesn't make a difference if change between access points of internet, rain or unrestricted. It's forced on band 3 and band 38 not making a connection. When initially got the sim to test out the 1 week the speeds were good at 20mbps. But now you can barely browse a website, it's a struggle to stream even in 144p. Do you think a router like b618 will make it better? Or is this network congestion?
