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.

Switching to a new SIM plan

Switching to a new SIM plan. Already on one of our older plans? As your minimum term has ended, you can switch to one of our new plans any time you like. It's really easy - we just move your new plan details on to your existing SIM.
