SIM plan benefits

Personal Hotspot If you're taking out one of our plans, you can use all of your data allowance as a Personal Hotspot in the UK. Unlimited texts All our plans come with unlimited texts, so you can send as many standard rate text messages as your fingers can type in the UK.

Use your phone abroad at no extra cost Our plans let you use your data allowance, text and call in the UK from abroad at no extra cost with Go Roam.



Available in over 70 destinations including Spain and New Zealand. Find out more about Go Roam. 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.
