5 ⭐ for Emma Harper Fixed the 2nd time occuring fault that Telsim should have fixed since last month when the same fault happened!.
Major problem with Telsim overall is that even though it's on the Telstra network you can't use their sim card in Telstra products! So you have to buy unlocked devices if available!.
