Comet Cloud is a paid service. With every purchased Comet device that is compatible with Comet Cloud, you get free and limited access to COMET Cloud. At any time, you have the option to purchase a recharge coupon for 1 year, 2 years, or more years of operation of the device. Extension of the subscription for individual devices is realized through credits from the wallet, which is built into the COMET Cloud. You can increase the credit balance in your COMET Cloud wallet as needed by purchasing a Top-Up Voucher. The unit price of the coupon is always for one credit.
