Hi! I've been running into issues for the last month or-so with inbound and outbound calls to my mobile phone on my Sim-Only TPG plan. It may have happened on previous occasions and I have worked around it (whatsapp, messenger), but today I have been particularly in need of my calling/mobile service due to the nature of the caller trying to get in touch with me,- and me with them.  I am unable to make, or receive calls. However, I am still able to send and receive text messages. I have full reception, and have so-far tried/checked the following: 1) Airplane mode is off 2) I have turned my phone off and on again (twice) 3) I have done a full network reset on the mobile phone 4) I have checked my account for call barring (it is disabled) 5) I have tried manually selecting the service provider in the sim settings and preferred provider. 6) I am inside the coverage area (Perth, WA) 7) I am not using a handset/headset 8) The earpiece is not broken. I know this because I am still able to make calls using messenger.   Thank you! ... View more
