Mobile operators have to certify devices, even if they don't include them in the portfolio.

This is a consequence of commitments to a country's spectrum management organizations.

If an operator expresses commitment, I would take this is a very important initial step, but not necessarily an indicator of full blown embracement of a platform. Operators will schedule time for a device to go through their certification labs. This means that a device can get approval from the regional spectrum bodies for qualifications that ensure the device doesn't interfere with authorized spectrum devices. Lab certification is not free- the operators are eating a cost. But certainly it's not the same thing as buying pallets of devices and trying to sell them to consumers.
