I just switched to an LG236C as my old LG440G was missing most of my calls. But activating it was a nightmare. It took the guys as walmart 2 days just to get it working. But now when I go to make a call I get a message that the call can't be completed as dialed, *67 and *82 can't be used for blocking...call again and don't press send? It takes about 3 tries to get through, all the while my minutes are being deducted too.
