When it comes to being the leader in terms of 5G coverage in the United Kingdom, Three undoubtedly checks all the right boxes. Even though the company faces stiff competition from arch-rivals such as EE and Vodafone, it has not only accelerated its 5G rollout since last year but also improved 4G and 5G speeds simultaneously. Not to mention, Three’s network reliability has also seen a similar improvement over the last couple of months.
One of the major selling points as to why any consumer would flock to Three network is because the company offers some irresistible offers on smartphones when signing up for a contract. Also, you can opt for unlimited data deals if the need arises and the best part is that your data allowance can also be used abroad without any additional cost.
What is more enticing is that Three’s 4G coverage in the UK is close to around 99.8 per cent while the 5G coverage currently sits at 56 per cent – both of which are highly competitive numbers. And as the company plans to roll out 5G further and faster in the upcoming months, the network reliability and service are only about to get better.
However, do remember that if you like to travel a lot, then roaming on Three’s network will cost you 2 UK Pounds per day in European countries and 5 UK Pounds for roaming outside of the EU. So, if you are ready to make the jump from your current network service to Three’s services and thereby enjoy all the benefits that the company is currently offering, then be sure to follow our SIM card activation steps below.
