Hi, I am planning to spend this winter in India. Mid-November to mid-February. Can anyone enlighten me as to which is the best way to get connected via a mobile phone? I will be using data to book transport and to stay in touch with friends and family Would buying a local sim and installing that have any issues with connecting to my Facebook and Whatsapp contacts? Has anyone used an Esim? any opinions on the pros and cons would be appreciated. TIA
