Wireless device transmissions to non-terrestrial networks face challenges due to limited link budgets, at least at mid-band Personal Communications Service (PCS) or Advanced Wireless Services (AWS) frequencies. An example solution includes a method that involves causing a wireless device that is classified or capable of a first power class to instead use a second power class (having a lower maximum transmit power) by default while operating in a terrestrial communication mode. Upon a transition from the terrestrial mode to a non-terrestrial mode (e.g., a satellite mode), the wireless device evaluates its connection with a non-terrestrial network with non-terrestrial nodes. If the evaluated connection does not meet certain success thresholds, the wireless device dynamically switches to the first power class to improve its connection to the non-terrestrial network. The flexibility in power class configuration for a wireless device uniquely allows a device to handle communications with terrestrial and non-terrestrial networks.
