Some people aren't totally sure whether Three has its own network or if it shares with one of the other providers. The answer is they do have their own network. And its customers rate it very highly for reliability.

The closest anyone else can get to All-You-Can-Eat data:
giffgaff offer a deal known as 'Always on' data that might seem to be offering unlimited data:
Unlimited texts
Unlimited mins
Always on data
on 4G
£20 a month
on a 1 month contract
The problem is: 'Always on' gives you get just 6GB of usage at the 4G speeds you're paying for. Then it downgrades you to just 2G speed.
There's no limit on the number of GB with 'Always on' but it will take you forever to use the internet!
Three's All-You-Can-Eat offers all your data at 4G speeds with the only restriction on P2P filesharing, which most people never use their phone for anyway.
Your frequently asked questions about Three's unlimited data SIMs, answered:
Is Three's All-You-Can-Eat data truly unlimited?
Yes. You can download and upload as much data as you like.
The only restriction is on P2P filesharing, which is slowed down at peak hours (15:00-0:00) weekdays and weekends.
This doesn't affect normal phone use like internet browsing, video watching, streaming etc, which you'll get at full blown 4G speeds all the time.
Don't giffgaff do an unlimited data SIM too?
giffgaff have what they call an 'Always On' data SIM for £20, which seems like it's unlimited data.
However, the catch with 'Always on' data is: once you've used up 6GB data, giffgaff will slow you down to 2G speeds.
Can I use this SIM for tethering (personal hotspot)?
Absolutely yes. You can use up to 30GB of data for tethering your phone to another device on Three's All-You-Can-Eat data SIMs.
If I take a 12-month contract, what happens if I want to leave early?
You've got 14 days after your purchase to send back your SIM and cancel free of charge. You'll only have to pay for usage up to that point.
If you're nervous about taking out a long contract, use the filters above to see just 1-month contracts. They're a little more expensive but you can always switch to a 12-month later and save.
