New Three Supercharged Pay As You Go!

In March 2020 Three updated their Pay As You Go offering with new data bundles, Go Roam and 5G as standard. This was quite an upgrade over the old 3-2-1 packages which were already well thought of.

Three PAYG SIMs come with data pack bundles that give exactly what they sound like – an allowance of data that you can use over the month. You don’t have to commit to a data bundle every month and you don’t have to always buy the same one – you can scale up and down or even take a break completely to suit your needs. Even though it sounds counterintuitive to buy a monthly bundle for a Pay As you go SIM or phone it is much cheaper than buying the same data allowance on a Pay As You Go basis.

Go Roam on Pay As You Go

Go Roam is a key feature for Three users that sets the standard for mobile roaming on any network so it is great to see it available on PAYGO. Now all Three users can use their phone abroad just like at home without running up a huge bill. 71 countries are covered including all of Europe and most key global holiday destinations including Australia, America and New Zealand.

No Credit Checks!

Don’t want to risk unnecessary searches on your credit history? Well don’t worry, Three don’t perform any credit checks for Pay As You Go SIMs or phones.

What's that £90 SIM deal about? Why would I buy that?

It does look a bit scary doesn’t it! Don’t worry, there is a perfectly good reason for the price. It gives you unlimited data for 90 days. That is enough for a long holiday or an entire term in education. Coupled with Go Roam it can be great if you are travelling regularly and don’t want to be bothered with extra admin (please note that unlimited data plans do still have some sensible usage limits when roaming).
