TalkTalk has launched a new All-in SIM for mobile users, offering unlimited calls, texts and mobile broadband data to its customers.
From today (Monday April 27th), the firm has upgraded its 30-day XL SIM to offer 'unlimited everything' to existing customers and new broadband subscribers.
TalkTalk says the tariff is "perfect" for those who love to talk or text a lot, as there is little need to worry about running up a significant bill.
Consumers can get their hands on an unlimited SIM for just £12 per month - a price it says is the lowest on the market.
The mobile SIM can be bolted onto triple-play broadband, phone and TV packages to create quad-play bundles featuring mobile services.
It can be used with existing mobile devices or new handsets, with consumers able to purchase up to five different plans.
TalkTalk's SimplyBroadband and TV Essentials customers can take one All-in SIM when they first join, and add four more - including two mobile devices - after three months.
TV Plus subscribers can initially buy one All-in SIM, on top of the free SIM that comes as standard as part of their package.
After three months, they can add up to three more mobile plans, including two handsets.
"Our XL SIM plan just went unlimited, so now you can say yes to unlimited minutes, yes to unlimited texts, and yes to unlimited mobile data, all for £12 per month," TalkTalk said.
"With our All-in SIM, the only thing you have to worry about is keeping your battery charged."
