TalkTalk is urging existing Plus TV subscribers to claim the free mobile SIM they are now entitled to as part of their deal.
From this week, all new customers signing up for the top-tier broadband bundle will receive a mobile SIM worth £90 as standard.
This allows them to use 100 minutes, 250 texts and 200MB of data a month as part of their TalkTalk subscription, at no extra charge.
But the offer is not merely restricted to new subscribers - it also applies to any customer currently signed up to the TalkTalk Plus TV deal.
"You can use your SIM in any unlocked phone, and even keep your existing mobile number," explained TalkTalk's Head of External Communications Alex Birtles.
"Just let us know if you’d like to do that and we’ll make all the arrangements."
She explained that calls between family members with mobiles on the same account can be made for free - ensuring TalkTalk subscribers get more for their money.
"We really hope you have fun using your extra minutes, texts and data," Ms Birtles added.
