Use Your Data as a Personal Hotspot

Three's contract SIM deals offer a range of great benefits if you don’t want to fork out for a new pay monthly phone. You can use all of your data allowance as a personal hotspot in the UK, while all of their plans offer unlimited texts and calls, which means you can send as many standard rate messages as you like in the UK without it costing you any extra.

Three’s plans also let you use your monthly data allowance abroad, as well as text and call the UK from abroad, at no extra cost thanks to Go Roam. This brilliant feature is available in more than 70 destinations, from France to Australia.

If you find yourself running out of minutes before your plan renews, you’re able to block any outgoing calls to ensure you’re not hit with any extra charges. You can also block calls and texts to numbers which are not included in your monthly allowance.

If you do find yourself running out of data halfway through the month, there’s no need to panic as you can buy more whenever you like through your My3 account. If you’re looking for some flexibility, you’ve got it.

Finally, as well as fixed data allowances, Three’s usage alerts for minutes and texts means you’ll never send more than you‘ve budgeted for. This all makes them a great alternative to expensive phone contracts. Don't forget, you can get an even better Three SIM only deal by taking advantage of our cashback offers.
