A: Yes you can, so long as you FIRST use the sim inside of a cell phone first.
Make sure your phone is unlocked
As well as confirming your phone’s compatibility, you’ll also need to make sure it’s unlocked before you can bring it to Google Fi’s network. Most carriers lock the devices on their network to keep their customers from joining another carrier's network before an allotted time. Be sure to review your contract with your current cell phone carrier and resolve any pending balances on your account before joining Google Fi.

 While all carriers have their own unlocking guidelines, you will likely need your:

Account number and information, including the owner's name and PIN
Social Security number
Device IMEI number

确保您的手机已解锁
除了确认手机的兼容性之外，您还需要确保手机已解锁，然后才能将其接入 Google Fi 网络。大多数运营商都会锁定其网络上的设备，以防止其客户在规定时间之前加入其他运营商的网络。在加入 Google Fi 之前，请务必查看您与当前手机运营商签订的合同，并解决您帐户上的任何未结余额。
虽然所有运营商都有自己的解锁指南，但您可能需要：
帐号和信息，包括所有者的姓名和 PIN
社会安全号码
设备 IMEI 号码
