FAQ
Common questions
Is 100GB enough for a primary home broadband replacement?+
For 1-2 person households who don't stream 4K video, yes. Average UK home broadband use is around 480GB/month — so 100GB on mobile only works as a backup or for low-usage households. Power users should look at unlimited 5G home broadband instead.
Can I use a 100GB SIM as a hotspot?+
Yes, all the plans we list permit hotspot/tethering use. Some networks (notably EE) impose a soft hotspot cap of 30GB/month on certain tariffs — we flag this in the deal description.
