I've ordered a new sim card yesterday 2pm as my existing one burnt out in in a water damaged phone. The sim card has not yet been dispatched and the last one took ages to arrive as well.
I have not found any shops that stock them in the meantime.
It's a shame you can't pay for a premium next day service when its your own sim card you need a replacement for. I don't want a free sim a week later I want my dispatched today via special delivery - need my phone up and running again asap
I then have to wait another 24 hours for the sim activation transfer process (once i get the new sim details)- all rather tedious.
Premium service would do all this for you for less than £10 (to include special delivery).
