Hello,
The module is advertised to come with a build in antenna but I don’t see any when I get the product.
From the past month I am trying to get into iridium network and send a sample message but I am getting signal strength of zero. So I am suspecting it is due to lack of antenna to communicate.
I don’t mind buying one but I just want some kind of conformation 
Thank you.
The product description https://www.sparkfun.com/products/14498 mentions needing a subscription to the iridum satellite network; is one being used? The module does have an integrated antenna, or you can add a (better) external one
Try some of the examples (after confirming account!) here https://github.com/sparkfunX/Qwiic_Iridium_9603N and see how that goes
Is it SPX-16394 you’re using?

I see an antenna socket but not an antenna built into the board.
The product page recommends the antenna below.

I see an antenna socket but not an antenna built into the board. So can anyone adapt the product description page?
