Does the oneplus 5T have an additional external storage?

[Android Central Question]

Does it have an external mini-SD card option?

 

[CallMeEric]

No, just the option of either 64 GB or 128 GB

 

[Aquila]

No, thank goodness. OnePlus has been doing that right since the start

You can use a USB-C flash drive or adapter to offload stuff.

Also I think you mean micro SD, mini SD hasn't seen widespread use in some time.
