Jio and Airtel have both released a list of compatible handsets\n\n\n\nBharti Airtel and Reliance Jio have released a list of supported mobile phone handsets that can be used with their newly launched 'WiFi Calling' feature.\n\n\n\nWhile Airtel supports only four brands -- Apple, OnePlus, Xiaomi and Samsung, Reliance Jio's WiFi calling can be activated on phones from 12 brands.\n\n\n\nBesides three of the four companies supported by Airtel, Jio's WiFi calling is supported on selected models from brands such as Vivo, Motorola, Lava, itel, Infinix, Coolpad, Google and Tecno. \n\n\n\nJio, however, does not support OnePlus, according to the list given on its website.\n\n\n\nIt should be noted that not all handsets from the above brands are supported.\n\n\n\nTaking the case of Xiaomi, for example, Jio supports only three, high-end models: Poco F1, Redmi K20 and Redmi K20 Pro.\n\n\n\nHowever, Airtel supports a wider range of Xiaomi handsets. Besides the above three, Airtel WiFi Calling works on Redmi 7, Redmi 7A, Redmi Note 7 Pro and Redmi Y3. \n\n\n\nAirtel's list of supported devices is smaller\n\n\n\nHowever, popular Xiaomi devices such as Redmi 8, Redmi 8A, Redmi Note 8, Mi A3, Redmi Note 8 Pro and Note 7S are not in the list of supported mobile phones.\n\n\n\nIt is believed that these will soon be added to the list on both networks.\n\n\n\nThe highest number of devices supported today are from Samsung. \n\n\n\nWhile Airtel lists 14 Samsung handsets, Jio supports over 75 Samsung models -- including practically all the recent models including Galaxy M30, M40, A50 and A10s. Samsung is one of Jio's key network partners.\n\n\n\nSamsung's high-end devices like S10, S10 Plus and Note 10 are also included in Jio's list of compatible devices.\n\n\n\nAs for OnePlus, it is supported only by Airtel's network as of now. The company supports both the 6 series and the 7 series, including OnePlus 6T, 7 Pro, 7T and 7T Pro.\n\n\n\nJio supports Google Pixel 3, 3A and 3A XL, none of which are found in Airtel's list.\n\n\n\nJio also supports about 20 models from Vivo, including V9, V10 and V11 series.\n\n\n\nAmong the cheapest models that are currently compatible with WiFi calling on Jio network are iTel S42, and several models from Infinix, Lava, Mobiistar and so on. These devices are currently available for around Rs 6,000.\n\n\n\nWiFi calling can be a life-saver for those working or living in large buildings, particularly on lower floors, and those living in rural and remote areas where cellphone signals tend to be weak.\n\n\n\nInstead of routing the call via the regular cellular route, WiFi calling patches the call through the local WiFi network. The feature works with any broadband connection, irrespective of who the provider of the broadband service is.\n\n\n\nYou can check out Jio's list of supported mobile phone models here, and Airtel's list here.\n\n\n\nVodafone Idea has not revealed any plans of introducing the feature yet. However, the company can be expected to unveil the feature later this year.
