All Three plans allow you to use any or all of your data to tether over a personal hotspot in the UK. That means those on unlimited data plans can enjoy unlimited tethering!
That's right, there are a range of Three plans with unlimited data which include free unlimited tethering. That makes them a great alternative to mobile broadband and even a viable temporary internet solution for your home or office – though for long-term home internet you should consider Three’s 5G home broadband or 4G home broadband.
We've put a few of the most popular deals in the table below for you to check out.

Tethering can use up a lot of data so you’ll probably want to monitor your usage. On Three that’s easy to do though. As it just comes out of your normal allowance, in most cases you can check how much data you’ve used and got left by heading to your My3 account here or by downloading the Three app.
Three plans taken out before July 12th 2016 include different tethering policies depending on the contract type and when the contract was first taken out. We've summarised the tethering limits for older plans in the tables below.
Note that we’ve included this data for your reference but in most cases customers will have been moved onto newer contracts, so the following is unlikely to still apply.
| Contract start date | Max amount of data that can be tethered |
| From 2nd September 2015 onwards | 12GB per month |
| 3 July 2015 - 1 September 2015 | 8GB per month |
| 29 April 2015 - 2 July 2015 | 4GB per month |
| 14 March 2014 - 28 April 2015 | 2GB per month |
| Plans before March 17 2014 | None* |
* If you have a Three Pay Monthly tariff which started on or before March 17th 2014 then tethering won’t be included and you’ll have to pay for a monthly personal hotspot add-on.
| Contract start date | Max amount of data that can be tethered |
| From 2nd September 2015 onwards | 12GB per month |
