Control your spending

Three allows you to block calls and texts to numbers that are not allowed, such as 0845 and 118 numbers.

Is Three a good network?

Three is one of the four UK mobile networks, the others being EE, Vodafone and O2. All other UK mobile service providers are in fact MVNOs (Mobile Virtual Network Operators) which are grafted onto one of these four. Three has always said their network was built for the internet and currently handles 36% of UK mobile data traffic, with Three’s customers using 3.5 times more data than the average Briton, according to Three.

Three’s 4G network covers 98.3% of the UK population and supports 4G Super-Voice, which gives you better indoor signal and clearer voice calls over 4G. In the last analysis published by OpenSignal, Three’s 4G network achieved an uptime score of 76%, meaning OpenSignal testers could get a 4G signal just over three-quarters of the time.

Data and calling features

More and more, mobile service providers are including additional data and calling features in their offerings to make your phone easier to use, and therefore life, a bit more. We’ve rounded up a few of the more popular ones, and now let’s take a look at whether Three offers them or not, and Three’s data speed.

• 4G data speed – Openignal Analysis shows that Three’s 4G network offers average download speeds of 18 Mbps. It’s a bit behind Vodafone and EE but ahead of O2, for comparison. Three’s average 3G download speed, at 8 Mbps, was the fastest in OpenSignal’s analysis.
• Data rollover – Three doesn’t offer any sort of data transfer scheme, but its plans tend to be quite data heavy, and there’s the Go Binge feature which represents some popular data-hungry apps.
• Sharing the line – Three wants to say that you can use your data to create a personal hotspot and connect with another device (a process known as tethering). And there’s no limit for that – you can use your entire data allowance this way if you want.
• Wi-Fi calling – Three is one of a growing number of providers offering wifi calling, a technology that allows you to make calls and send text messages over wifi when you don’t have access to a mobile network (3G or 4G).
• Data donation – Three doesn’t have a data donation program in place, but you can use tethering to help your friends and family get online using your data allowance.
• Data Limits – Three lets you control your monthly spending by blocking your phone from calling certain numbers, but the provider doesn’t put any kind of data cap in place.
