Hi, I am currently overseas. I used my local Australian Sim for the first two days on roaming in Japan with no issues and then chose to purchase a local data sim. I put my Oz sim back in a week later to check my messages and I have no service at all. I am overseas for another 4 days in The Philippines. The Yes Optus app says I am not registered on the network and I am unable to recieve or send any calls, messages or data. I desperately need it for work!
Kind regards,
Charmaine
