What carrier is AirTalk Wireless with?

Could you please clarify for me which carrier AirTalk Wireless operates under? I'm interested in understanding the network infrastructure and coverage that AirTalk Wireless provides to its customers. Is it a subsidiary of a larger telecommunications company, or does it have its own independent network? Additionally, how does AirTalk Wireless compare to other carriers in terms of pricing, data speeds, and customer service? I'm eager to learn more about this provider and how it Stacks up against the competition.
