Difference between old SIM card 3G and newly released SIM Cards on 3G

Answered

Guys,

 

I currently have a mobile device that connects to the telstra 3G network via a Telstra SIM card. This has been working correctly until now. I have purchased a new SIM card and the device will not even recognise the presence of a telstra SIM.

 

However when I put a SIM in from another carrier or my old Telstra SIM it works fine.

 

Can you please explain this, has the PAD out on the SIM cards changed? If so why?

 

Thanks for your time

Just to be sure, the “newly released SIM card” is a mini-SIM (of the same size as your old one) and not a micro-SIM (which is smaller in size), right?

It is a mini SIM it looks the same size as the old one and no its not a micro SIM.

 

The PAD out does look different that is what's concerning me. I have also been reading that some SIMs require 3.6v and other require 5v. This may be the issue as well if the have change the voltage.
