DO NOT BUY THEIR PREPAID PLAN
DO NOT BUY THEIR PREPAID PLAN! I had the prepaid plan for a year when I was on a working holiday visa in Australia, and thought that since it was a one time purchase, it would end once the year was over. But just a few days ago, I got a tax invoice telling me that they had taken my money for yet another year. I tried to get through customer service to get a refund, since I won’t be using the mobile plan again, and they just said that since I had auto recharge enabled, they couldn’t do a refund? This is not something I have manually done, and there was in no way any consent from me for them to do this. No email or anything, asking me if I wanted to go through with the payment. Absolutely ridiculous, and I’m beyond frustrated with this company.

Telsim had auto recharge enabled by default without user consents and took ppls money without remorse. the Australia government is not doing anything to protect the consumers. Shame on the Government leaving Telsim doing all this. i would think the government has shares with Telsim.

Bad experience. No understanding from customer support
Telsim does not support google pixel 9 pro. Before the activation process of the esim was completed, I asked to cancel my order and a refund, but support didn't help on that. They charged me for a service that I couldn't use. The list of supported devices is limited.

Awful service
Purchased a sim card, and then when I went to activate it, they told me that the email address which I have been using for the last 20 years 'is not valid'.
Then proceed to tell me I should register for a gmail account. Since when do I have to have a gmail account just to buy a sim card!
Then told me that they wouldn't give me a refund !!!!
