This category is for discussion of the Librem 5 phone products, the phone operating system, and apps that either Purism or third parties are working on. Ideas for apps are also welcome! Discussions about PureOS in general or other products are more appropriate in other categories.
Before posting questions about the phone, take a look at the Purism FAQ page to see if your question has already been answered. In particular, the answer to the What are the phone specs? question may contain the information you are looking for, and the page about modems in the developer documentation may also be useful to you.
