It's detailed on this page as "6 months internet access": https://www.t-mobile.co.uk/services/payg/boosters/ https://www.t-mobile.co.uk/services/payg/boosters/ I'm generally more concerned with low latency than high bandwidth on my mobile connection. I tend to use SSH on my phone on a fairly regular basis and I've found T-Mobiles network to be very low latency in comparison to others.
