Google Project Fi now offers additional data-only SIM for 4G LTE devices such as tablets to its existing customers without per device fee, a standard feature among mobile operators across the globe. Google Fi customers can add up to a maximum nine devices to a shared data plan at a flat rate of $10/GB billed monthly. According to Google's help forum page, the option for data-only SIMs should rollout to customers in the next couple of days. Users, however are not allowed to use these data-SIM devices for tethering.
Google launched Fi earlier this year as a partnered project with US carriers T-Mobile and Sprint. The service allows users to make calls, SMS messages, and data connections at a flat rate of $20 per month and $10/GB respectively. The data charges will be pro-rated if customers use more than the allocated quota and refunded if they have any remainder at the end of the month.
