Hi @RobLauer,

I am planning purchase blues stuff to use in India using external sim card because notecard doesn’t cover my country. May I know the difference between note carrier A and F? also please giving me suggestions on list of my items in the cart. Thank you for your valuable time.

Hi @Srihari,

There are quite a few differences between the Notecarrier A and Notecarrier F, most importantly the F provides a socket for plugging in a Feather-compatible host and it supports [Notecard Outboard Firmware Update](https://dev.blues.io/guides-and-tutorials/notecard-guides/notecard-outboard-firmware-update/#notecard-outboard-firmware-update) without any additional wiring. Notecarrier A includes onboard antennas and (through the exposed headers) can connect to any host MCU.

The items in your cart look good!

Rob

Is it a Feather-based MCU? Use the Notecarrier F.

If not, use the Notecarrier A.
