I have a usage question. I have looked at the O2 website on WiFi and 4G calling but have questionsthat are not answered. They are as follows:
1) How is it initiated? The website says 'when the signal is poor' so do I use my phone allowance as normal but if the signal is poor does the 'phone use wifi or 4G automatically or do I have to initiate?
2) If I am abroad and have wifi can I use wifi calling to call home without incurring roaming charges?
3) Do I leave wifi calling 'off' on my 'phone (iPhone 7) until/unless I wish to use it or do I leave it on?
Hopefully someone from the community can help with these questions.
Solved! Go to Solution.
Thanks MI5 for clarifying, how do you get your knowledge?
Further to the comment I made about calling home from abroad, do you know of an app that I could use to call back to the UK using wifi? I am going to Egypt in October and will be taking a 'MiFi' device with me and will use a local sim to provide a data connection, just wondered if I could use this to call home via wifi!?
