Help and FAQ
How much do unlimited data plans on Three cost?
Prices vary depending on the type of plan you opt for and the phone you couple it with. Pick a mid-range phone and unlimited data plus 600 minutes and unlimited texts can be had from around £40 per month on a 24 month contract.
If you don’t need a new phone then you can opt for an Advanced Plan SIM Only tariff, which on a 12 month contract gives you unlimited data, 200 minutes and unlimited texts for just £23 per month, or for a more flexible 30 day contract you can get the same allowances for £26 per month.
Is Three’s unlimited data really unlimited?
With an unlimited data tariff on Three use can be capped at around 1000GB per month. This cap is used to identify inappropriate use of the service, such as commercial use, which isn’t permitted. However for non-commercial use it’s very unlikely that you’ll ever get anywhere close to the cap, even if you use your phone as your main or only internet device.
Can I use my data when roaming abroad?
Yes, with Three's Feel At Home service you can use your allowances in 18 international destinations at no extra cost. However there are some minor restrictions, including the use of data, which is capped at 12GB if you’re on an all-you-can-eat data tariff. But in most cases that should still be more than enough for even the longest of holidays.
Where can I use my data?
You can make use of your data anywhere in the UK, just as long as there’s coverage, which in most cases there will be, as 98% of the UK population receives 3G coverage and over 63% can get a Three 4G signal. You can also use it outside the UK free in Feel At Home destinations, subject to the 12GB cap detailed above.
Feel At Home is expanding its reach all the time, but if you want to use data somewhere where it isn’t currently offered roaming charges will apply.
Can I use unlimited data for tethering?
Yes, if you have unlimited data you’ll be able to use it towards a Personal Hotspot (aka tethering). The only restriction is that you can only use a maximum of 30GB per month tethering.
Can you get unlimited mobile broadband?
No. While all Three's phones and mobile phone SIM cards have all-you-can-eat data plans its tablets, tablet SIMs, dongles and MiFi don’t.
However, they do still offer generous allowances of up to 20GB of monthly data with a MiFi device, tablet or dongle or SIM card.
That's more than enough for most users and as an example 15GB of data allowance per month will enable you to:
- Send 15000 Emails
- Browse the internet for 150 hours
- Download 75 4 minute videos
- Download 480 4 minute songs
What is TrafficSense?
TrafficSense is Three's management of data traffic and is a way of ensuring the best possible mobile internet experience is given to users.
In general you won’t notice this at work, the aim is to give you a smooth experience and if that’s happening then TrafficSense is doing its job. However in order to achieve that some types of data use will see small restrictions at certain times.
For example between 3pm and midnight a certain amount of bandwidth will be dedicated to tethering and file sharing, ensuring that the use of those services doesn’t hamper general mobile internet performance.
Is my speed capped?
Currently there is a limit to the speed you'll get from Three, but that speed is increasing, with the network recently boosting speeds by up to 50% above the previous 50Mbps cap. This is easily fast enough to ensure a great experience and allows even HD videos to be streamed smoothly. The cap is in place to ensure Three's network is spread correctly across all users, so no-ones experience is hampered by anyone else.
