Google has unveiled a mobile phone service that gives customers better network coverage but keeps their bills low, in a move designed to put pressure on its telecoms rivals.
The search giant has pushed further into the mobile sector by teaming up with US carriers Sprint and T-Mobile to launch Project Fi.
Customers signed up to Fi will be automatically switched between free Wi-Fi hotspots, Sprint and T-Mobile depending on which offers the better phone signal.
Instead of signing up to a strict monthly contract, people on Google Fi will only pay for the data they use. So, if you pay $30 (£20) a month for three gigabytes (GB) of data but only use 1.4GB, Google will give you $16 (£10.66) back.
A study in 2013 by Validas found that smartphone users typically waste $28 (£18.66) a month on unused wireless data.
Users’ phone numbers will also be cloud-based, so they can talk and text with their number on any phone, tablet or laptop.
“So the next time you misplace your phone, you can stay connected using another screen,” Google said.
The project is expected to put pressure on telecoms rivals such as AT&T and Verizon in much the same way Google has forced broadband suppliers to improve their services after launching Fiber, which is 100 times faster than the average US broadband connection.
With better phone reception and cheaper contracts, Google hopes customers will visit its sites, such as YouTube, more often.
Google Fi will initially only be available in the US and on Nexus 6 phones, which the firm developed with Motorola.
