What's New

Version 3.7.0

It's a brand new year, so we've got some brand new features for you. Here's what we've been working on to get through the January Blues:

We've made bill breakdowns clearer.
Use our new Call Checker page to see if a number will cost you to call, and how much.
Confused about Wi-Fi Calling? We've added a page to explain it.
We'll give you a little reminder to switch Wi-Fi back on if we need you to switch it off.

And last but not least - we've snuck a (super addictive) game in there. Bye-bye boredom.

I change over to Three 6 months ago from O2 which I had been with for over 10 years. I had a new iPhone at the time so took up a SIM only contract that allowed me to use my data in many countries outside the EU for free and was surprised how great the Three packages are for traveling around the world (make Russia your next ‘home’ place please); easy to understand, flexible to change and transparent with costs and billing.

Since being with Three I doubt I will change provider unless there’s a better offer out there. The only down side to Three is the week signal coverage in some areas of the UK but apart from that... they rock!

Oh and the new Three app they have is incredibly helpful and makes it easy to keep track of your bills and package allowance. Keep it up Three. Bye bye stingy 02.

I’ve been with 3 for about 2 years now, never once have I lost signal. I’ve always either got either 3G or 4G even in places with o2 I could barely get a bar of signal!!. Occasionally inside was an issue where I lived in the sticks but then WiFi calling came along which sorted that, then they put up a mast so now I get 4G..... wouldn’t choose another network now, the unlimited internet is a godsend. While my mates struggle with their limits I just stream away! All day every day!. I’m a lorry driver so I go to some pretty rubbish in the middle of nowhere places, look at my phone expecting nothing and have 3G! I dunno how they’ve gone from apparently having rubbish signal to the best signal I’ve ever come across but I love it!. Thanks
