Does anyone know how to fix phones? My phone has a standard sim and i bought a new sim to go with a new phone. EE sent the wrong one! They sent a nano sim instead of a micro sim. I can't use my new phone. I took my standard sim out of my phone to check it compared to the nano sim, then put it back in and i cant send or receive txts. It says i can only make emergency calls? What's happened, as basically i have taken the sim out and then put it back in and it won't work....
