Is Three a good mobile phone network?

As always, this depends what you're looking for. Three is an industry veteran with a solid 4G and 5G network. 3's truly unlimited data offering also holds appeal for those that consume large amounts of data every month. Flexibility of contract length is one limitation, so if your priority is a short-term deal with flexibility to move around or change contract, then you will definitely want to consider other options.
