Telsim not reliable and customer friendly
Worst experience with Telsim. Even though it runs on the Telstra network, they block incoming SMS just 24 hours after your recharge expires. This is basic functionality that most providers still allow. Poor service, poor policy, and not customer-friendly at all. Much better to go with Telstra, Amaysim, or Optus.
Your reply is not matching with your confirmed official call records I have and official verbal call recording I have. !! Says. 24 hours after validity expires u bar incoming sms and also can bar incoming calls. If you want I upload here ! U want me to upload it ? Or even ur email ??

We’d like to clarify that the you have contacted us 10 days after the plan had expired.
Incoming services like SMS are only available for a limited time post-expiry as per plan terms. Additionally, eSIM activations are typically completed within minutes when all submitted details are accurate and successfully verified.

Not worth the hassle
Wow evey step of the way trying to get the esim activated there were issues. And you cannot activaye early as you can only activate upon arrival. Better of buying a physical sim at the airport

We’re sorry to hear about your experience and appreciate your feedback.
Our eSIMs are designed to activate upon arrival to ensure full validity during your travel period. While most activations are smooth, we regret that you faced issues along the way.
We’re continuously working to improve the activation experience and appreciate you sharing your thoughts.
