Mobile BB USB stick

[Deleted User]

I need some advise b4 I buy the T-mobile BB usb stick E3131. I wanted to get this for when I visit my mother's house who doesn't have BB so that I can still acces email and general surfing. Can someone please help me with the following questions

I understand that when I top up with £10 am I correct that when I go online I will be charged £2 per day. Will any unused credit be c/f to the next month.

What happens if I exceed the 250MB allowed in any 1 day? Probably unlike in my case but worth knowing.

I'd appreciate you help

When you go online, you will be re-directed to a T-Mobile page where you can select a package. A one day package is £2.

If you use up 250MB, you will still be able to surf and send email, but downloading may be curtailed for that day.
The rest of your credit stays unused until you buy another package.

Thank you NiftyDigits. This sounds just what I need.
