@Bell1984 Did you check that there was good coverage before you joined? always worth doing for a new network that you are going to try.
If you have only recently joined, then hopefully you have not wasted a lot of money. The good thing about Smarty is that you're not tied in to a long contract and can leave after a month if it is not suiting your needs.
Unless you have tried every network, then you cannot really say it is the worst network ever. Also, concealing swearing with other words doesn't really help your case.
