Three Data SIM Card – Preloaded Data

Getting a router, dongle or tablet online is easier when the data is already on the SIM. These Three data SIMs come preloaded with an amount of data from 1GB to 24GB, so you can pick a small one for occasional use or a larger one for regular browsing. The SIMs use Three’s own 4G and 5G network.

Check your device first

• The device must be unlocked, or locked to Three.
• It needs a SIM slot. The card is 3-in-1, so it fits standard, micro and nano slots.
• It is a data SIM. If you want calls and texts, go for a Three pay as you go SIM instead.

Data options

• 1GB: £9.99
• 3GB: £13.99
• 12GB: £32.95
• 24GB: £49.99

The data amount in each option is what is loaded onto the SIM. When you need more, you can top up the SIM with Three or with our Three top-up vouchers.

Postage and payment

Pay by UK bank transfer. Once the payment reaches our account, we post the SIM by Royal Mail to your UK address. Postage options are shown at checkout, from Second Class Signed at £2.95.

To stop Three closing the number, put it to paid use at least once in each 180 days. A top-up counts.

Questions

Which size should I choose?

For email and light browsing on a tablet, a smaller amount may last a while. For a home router or video calls, a larger amount makes more sense.

Can I put it in my phone?

Yes, if the phone is unlocked. You will get mobile data, but it is not meant as a calling SIM.
