Mudita Pure is a stand-alone phone, compatible with most telecommunications service providers and that monthly fees depend on the operator they choose. Pure is able to operate on network frequencies in Europe, North and South America, Australia, Africa, and Asia. Your phone will officially work on dozens of mobile networks around the world.
However, Verizon and AT&T in US are currently not working with Pure. This is due to internal certifications that Pure is not able to fulfil without compromising current low SAR value. We recommend using T-Mobile in the US.
