I have Metro PCS as my provider and the Samsung sch-r410 for my phone, I'm not sure if it's my phone or Metro but when I try to text some people it repeatedly fails sending 3 times, no matter how many times I attempt to text some people it just never sends, the only way I can text them is if they text me I can reply, so I have to lock one text message from everyone I know it won't send to if I want to text that person. Does anyone know why this is happening and if the problem can be corrected? Thanks in advance.
