I will be revisiting South Africa. As before, I will use a Pay As You Go local sim in my old dumb phone for local calls. I will not be using my new PAYG Samsung S21 for sending sms texts or calls back to UK. I only need it for logon authentication codes texted by UK banks, etc. I will connect mostly via wifi or sometimes via a local network. My understanding is that I do not have to enable O2 Travel for incoming sms texts and calls which should be free? My thanks in anticipation to whoever can confirm my thinking, or otherwise!
