Evening all,
I'm coming towards the end of my 12-month SIM only contract with T-mobile, which is £9.50 per month for 300 mins, unlimited texts and unlimited internet.
However, they have baffled me by saying I use 37GB of data per month!! Now I use my lumia 710 to do betfair, BBC sport, a few apps, yahoo email for circa 2 hours a day - surely that can't be 37GB of data per month??!! ... Or can it?

Are they telling fibs to make me think of staying with them?
As I was thinking of going to Three or Virgin, but am worried about potentially high data costs.

T-mobile annoy me as they charge for lyca mobile calls, voicemails and 0800 calls (but don't charge extra for data).

Any advice or experiences appreciated folks ...

What does the data counter on the handset suggest?
3.7gb maybe more realistic, a colleague had used 11gb in a month, he wasn't streaming as such , just the data was clocking up on his handset after he had visited youtube.
