Is there a ‘rough’ coverage map for the US? Particularity need to know coverage in rural/agricultural areas of the country. ---

Hi @jderimig and welcome to the Blues community! There are contractual reasons why we cannot provide a coverage map (we can’t publicly state who our carrier is in the United States). It is a major carrier and we work with their roaming partners globally. If you run into coverage issues, it’s an option to use an [external SIM](https://dev.blues.io/guides-and-tutorials/notecard-guides/using-external-sim-cards/#using-external-sim-cards) (though I can understand why that is not always ideal). We also recommend using one of our “wideband” Notecards (any that start with WB\*) as those tend to establish faster and more robust cellular connections. Rob ---

Rob, thank you for the reply. Can I assume that a WB card is plug and play with a system prototyped with a NB card? ---

Yes, 100% compatible.
