Mobile phones on Pay as you go

• All the allowances in a Smart Pack last for 30 days. At the end of the 30th day we'll take your next payment and a new pack will start automatically (unused minutes, texts and data don't roll over, though).
• If you don't have enough credit we'll let you know - so you can top up and text again to buy another pack.
• You can see how much data, minutes or texts you've got left at any time by simply texting BA to 150.
• We'll remind you by text when your new pack is about to start, and if any of your allowances run out before the 30 days.
• If you're already on T-Mobile pay as you go then you'll need to make sure you are on our Everyday plan before you buy a pack. Just call 146 to check, or text EVERYDAY to 146 to change. Smart Packs are not available with any other T-Mobile plan.
• If you want to change your pack, first text STOP plus the name of the pack to 441, then wait for your current pack to expire (we'll tell you when that happens). You can then buy a different Smart Pack in the normal way.
• If you move to another price plan while a Smart Pack is active, you will lose any remaining minutes, texts or data you haven't yet used.
• And remember, whatever pack you choose you also get terrific coverage as you'll be using EE's 3G network, the biggest in the UK.

Get a Smart Pack in three easy steps

1 Get a free T-Mobile SIM
2 Top up
3 Text your chosen pack name to 441

Then use your smartphone as you want for the next 30 days

Want one? Well, it's easy.

Once you've joined T-Mobile and topped up, you can pick a Smart Pack any time you like. Text SMART and the value of your pack to 441 (like SMART10 for a £10 pack). For BlackBerry® Packs do the same, but text BBPACK (so BBPACK10) to 441.

The money will be taken from your credit, so make sure you've topped up first.
