Find the Best Fit
Mudita Kompakt comes in two versions - Global Optimized and North America Optimized - designed to provide the best connectivity in different parts of the world. Mobile network technologies and the frequency bands they use can vary significantly by region.
The primary technical difference that impacts your connection is the specific set of 2G, 3G, and 4G LTE frequency bands each version supports.
To ensure the most reliable connection with your mobile carrier:
Identify Your Carrier's Bands: Check which specific 4G LTE bands your local mobile service provider uses. You can usually find this information on their website or by contacting their support.
Compare with Kompakt Specs: Match your carrier's bands against the detailed list below for each connectivity version.

If you primarily use your phone in the US or Canada, choose the North America Optimized version for the most consistent and reliable connectivity on local networks.
