A humble request to all dear Apple iPhone India customers and tech executives. All the customers in India are using latest mobiles in which the new technology called 4G+ is used. But Apple is only showing 4G on iPhone till date. iPhone 12 and above models are said to support 4G+. But 4G+ is not actually coming. This should be made original in the upcoming update.
