Why am I being charged a dollar each time my phone rings, even when I don't take the call? Seems like a rip-off, for the "roaming enabled" feature offered by Optus.
Hi @N_H, the call is perhaps being diverted to Voicemail which is back in Australia so roaming rates will apply. You can turn off voicemail or unconditional diversions to stop this from happening. There's more info in the FAQ's here → https://goo.gl/dRHu7Y
