BT Mobile Broadband
Who are BT?
Best known for it's fixed line broadband, BT hasn't done much involving mobile networks since the days of BT Cellnet, instead concentrating on its free nationwide Wi-Fi network to capture broadband users on the move.
But recently BT has started to branch out into mobiles once more, offering SIM only deals for smartphone users.
What's particularly attractive about a BT SIM only deal is that they're available at a reduced rate for BT home broadband customers - if you get your fixed line broadband via BT you can also enjoy a £5 discount on all BT SIM deals.
BT Mobile uses the EE network so coverage is extremely good, and it also includes access to 4G mobile broadband where available.
