Hi, I have accumulated a lot of prepaid credits on my Telstra Pre-Paid Mobile Broadband Data Pass plans.
I have tried to insert the sim in my android mobile but I cannot buy anything from google play that way.
Would I be able to buy things on google play if I had a sim enabled tab or would it be enough to use a portable router (using the sim in the portable router) and then buy things from google store?
You should be able to use your Recharge credit balance on Google Play assuming you are on the original data pass offer. The sim needs to be inserted in an Android device.

More recent activations are on Data Pass 2 and cannot be used with Google Play
