My local Digital Store and xpress mini say they are now out sims. New sims coming out on monday as per them.
If you buy a new high end phone from them though, they are willing to "help out" with issuing the sim without standing in the queues when the new lot of sims arrive.
One guy came from outstation to buy an S7 Edge but they couldnt offer him a sim the same day, so they must be really out of sims at my store.
