TalkTalk broadband customers who sign up for a Samsung Galaxy S6 through the service provider now receive double data when they buy online.
The new handset - which went on sale today - is available from TalkTalk Mobile from £35 per month, with Small, Medium, Large and Extra Large plans available.
Each tariff comes with double the usual mobile broadband data allowance, giving TalkTalk customers extra incentive to upgrade their smartphone or sign up for their first device.

Consumers signing up for the Medium tariff pay £37.50 per month for a free handset, 500 minutes, unlimited texts and 1GB of data.
The Large plan currently offers a free Samsung Galaxy S6 32GB Black, 1,000 minutes, unlimited texts and 2GB of data for online subscribers - for £42.50 per month - while the top-tier Extra Large deal comes with 2,000 minutes and 4GB for £47.50 per month.
According to TalkTalk, the Samsung Galaxy S6 is crafted from "the finest materials", offering a full metal and glass design that consumers are sure to love.
"Ultra-thin, the Galaxy S6 is full of cutting-edge technology, from the stunning 5.1" QHD Super AMOLED display to the 16 Megapixel camera that launches in just 0.7 seconds and boasts fast tracking auto focus and f1.9 aperture for better low-light photos," the firm stated.
"Samsung also includes fast-charging technology that will give you four hours' use from a ten-minute charge."
TalkTalk Mobile deals are only available to customers who sign up for the firm's broadband and line rental services, with or without inclusive calls and TalkTalk TV.
The current double data promotion applies to any TalkTalk subscriber who signs up to a monthly SIM plan, 24-month tablet bundle or smartphone online.
