Huffington Post and O2 have teamed up to present three challenges using the TU Go App. Presenters Zoe Salmon and Matt Edmonson from Huff Post, have taken the challenge under their belt to use the new revolution app from O2.
This first challenge sees Matt in a basement at youth homeless charity Centrepoint without a phone signal, watch the video in the featured player above to find out how he gets one!
The TU Go App frees up your O2 mobile number to roam across all manner of devices, from tablets to PCs, and even lets you make calls over wifi when you lose signal, a real bonus if you find yourself working out of doors.
