National UK telecoms operator BT has begun offering its new superfast 'up to' 40Mbps FTTC broadband (BT Infinity) packages alongside a 3 Months FREE service promotion, but only when bundled with one of its weekend or anytime home calling (phone line rental) deals.

The new promotions are part of BT's Springwatch special offers, which also includes a basic 'up to' 20Mbps broadband + Evening and Weekend Calls promotion that offers the first 4 Months of service for FREE. Full details can be found below.

It should be noted that the £18 per month BT-Infinity package, despite claiming to offer a "free connection", will still charge a £25 activation fee but only if you're an existing BT customer. However, the £28 deal makes no mention of any activation fee in its small print.

It's also still possible to take the "Unlimited" BT-Infinity service as a standalone broadband package; although it'll set you back £25.60 per month and does not come with any special offers.
