LYF EARTH 1 is a good device by the company. Its for the jio 4g sim. And comes with the sim also. Its the new entry of LYF into smartphone market and a phone with price range of around 20000rs its that promicing as people would only spare money upon some reliable brand as its never easy to earn. Also its not that impressive and outstanding in terns of looks and specs. Its a decent device. You could surely go for other better 4g phones like moto g4 plus, le l2 etc which are for more better and cheaper than this device
