SIM Troubles

My SIM card is starting to show it’s age and refusing to allow my phone to connect to the network. It’s not surprising as the thing is fairly old having had it since I first joined T-Mobile. I managed to order a new SIM yesterday throwing only a minor strop when they suggested I pay for it. However despite a final buff of the contacts it totally gave up the ghost this morning. It will be a few days before I’m available for GSM based voice chat again. Of course I remain very contactable by numerous other methods
