OptimERA Inc., operating in the United States of America (North America & Caribbean region), is a mobile network provider recognized under the Mobile Country Code (MCC) 313 and Mobile Network Code (MNC) 380. While detailed public information about OptimERA's specific subscriber base and coverage area is somewhat limited, its existence is confirmed through its allocated MCC and MNC, essential identifiers for mobile network operation within the global telecommunications infrastructure. These codes are crucial for devices to correctly identify and connect to a specific mobile network when roaming or registering within the OptimERA network footprint. Compared to larger national carriers like Verizon (MCC 311, MNC 480), AT&T (MCC 310, MNC 410), and T-Mobile (MCC 310, MNC 260) that boast extensive nationwide coverage and millions of subscribers, OptimERA likely serves a more niche market segment, possibly focusing on specific geographic areas, business sectors or innovative technologies. While specific details on OptimERA Inc.'s technology (e.g., 4G LTE, 5G) or services require further investigation, its presence in the US mobile landscape highlights the diversity of providers operating within the highly competitive telecommunications market in the United States.
