SIM plan benefits

Control your spending

If you run out of minutes, you can block outgoing calls so you don't run up any extra charges. Plus, you can block calls and texts to numbers that always fall outside of your allowance (like 0845 and 118).

Add extra data anytime

Don't worry if you run out of data halfway through the month. You can buy more anytime you like in your My3 account, giving you all the flexibility you need.

Set usage limits and alerts

Along with our fixed data allowances, our usage alerts for minutes and data make sure you never spend more than you planned.

What is SIM Only?

What is a SIM plan?

A SIM plan is just that – no phone or tablet, just data, minutes and texts. If you're happy with your device and don’t need a new one, a SIM plan is your best bet. We've got a wide range of Pay Monthly and Pay As You Go SIMs, so you can find one that best suits your needs.
