To surf, YouTube, stream live…
You mean the speed?
So for surfing and occasionally YT 5MBit / s will be enough - I had it for a long time and was always enough.
But a livestream about the latency from a mobile network… - no idea whether that works - have never streamed…
Movies consume a lot of data. You put a SIM card in the internet stick, then you have a limited volume on the SIM card that you pay for. An unlimited data volume costs from 30-100 euro per month. A data speed of 5 - 10 Mbit / s is necessary.
Pay unlimited 19.99 mtl at 30 mbits
