Pay as you go

Only pay for what you use with pay as you go (PAYG). Order a free sim and pay for calls, texts and data only when you need them. PAYG is more expensive than monthly plans for the same amount of data, but if your usage is sporadic it may be worth your while. Here’s how much Three PAYG will set you back:

Calls (per minute) Texts Data (per MB)
10p 10p 5p

 

Data Pack 

Three Mobile data packs offer unlimited minutes and texts, and let you choose the data allowance you need every 30 days. All you have to do is choose the data you want for the next 30 days and buy one of the following Three Mobile data packs on Amazon:

  12GB 30GB 50GB Unlimited
  £10 £15 £20 £35

Prices have been included as a guide - they’re correct at the time of writing but may change. Data packs are different to monthly plans because they’re commitment-free. It lasts a month and you decide whether to renew or not.
