Telecoms giant BT has announced its return to the mobile phone market with the launch of its new network that will give customers cheap access to 4G internet from as little as £5 a month.
BT Mobile is offering three "incredibly competitive" 12-month SIM Only deals, with the best deals available to existing BT Broadband customers.
The cheapest deal will get you 500MB of 4G data, unlimited texts and 200 minutes for just £5 a month, or £10 if you aren't a BT Broadband customer.
The middle tier tariff offers customers 2GB of data, unlimited texts and 500 minutes for £12 a month (£17 for non-broadband customers), while its high-end deal will get you a hefty 20GB of data with unlimited texts and minutes for £20 a month or £25 if you don't have broadband.
Customers signing-up will get free access to BT Sport through an app on their phone and unlimited access to five million BT Wi-Fi hotspots around the country, while parental controls and spending caps come with all three tariffs as well.
The move is expected to be the first of many as BT develops it strategy in the highly lucrative mobile market over the next few years.
Ernest Doku, telecoms expert at uSwitch.com, said: "After a long time away, BT is throwing its hat back in the mobile ring with an incredibly competitive set of SIM Only tariffs – provided you're an existing customer.
"In a time of hand-me-down smartphones, BT's plans are perfectly poised to become a disruptive part of its consumer strategy – and that's before the EE acquisition comes into the equation.
"Existing customers get a deal that plants BT firmly ahead of TalkTalk and Virgin from just £5 for 500MB of 4G data."
He added: "With superfast speeds on top, its 4G offering is another selling point that gives BT Mobile an edge over the rest. BT's capped contracts, parental controls and shared billing offer peace of mind for users and make this an ideal offer for the family. Sports fans will welcome the addition of the free BT Sport app, a huge draw for new customers sitting on the fence."
BT has been out of the mobile marker for a decade, after selling 02 in 2005. It was announced last year that BT plans to buy EE.
