Is anyone using Smarty mobile for a data link? I'm hesitant to try them at the moment as it seems you can't pick up the SIMs from stores, only posted to you. Their deals are great at the moment, 100Gb for £15 PAYG per month. I suspect the speed is heavily restricted as it is the case with Three's unlimited PAYG SIM.

I'm curious to hear if anyone has any experience of them?

Cheers
