I left the phone and want to know if I can turn on data to locate the phone from my account.
I’m not sure if this article helps but you might give it a read.
I’m afraid there’s no way to turn on cell data remotely if it’s turned off in either the Republic app or Android settings. If it’s a matter of changing the plan on the phone to one with data, that may be possible. You could try using this undocumented Republic website: Republic Wireless.
Additionally, this Google website can’t tell where your phone is but might be able to tell you where it’s been recently: https://www.google.com/maps/timeline?
