I checked the 5G bands used by the providers against the list on the Murena site. The FP5 is missing n40 (used in a few non-Eurpean countries and Lithunia, and reserved in a few more European countries) and n78 (used in Austria, Belarus, Belgium, Bulgaria, Croatia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithunia, Luxembourg, Malta, Monaco, North Macedonia, Norway, Portugal, Romania, Russia, San Marino, Slovakia, Spain, Sweden, Switzerland, United Kingdom). The two gigahertz bands n257 and n258 are also missing. They are also reserved in some European countries.
While I can believe that the gigahertz bands are missing for tech reasons, I very much hope that n78 is missing due to an editorial error. Anybody know if this band is really something one would miss?
Does anybody have a source closer to Fairphone B.V. for a definitive list of 5G bands? Or the name of the relevant chip?
