I have a group that I text to, a sports team, but two of my contacts in the group don't get my messages. They bounce back to me because they are sending to their land phones! Obviously there are multiple phone numbers for these contacts, and the first time this happened I went into the contacts to set the mobile number as default - but that makes no difference. Google Android still tries to send them to the landlines! My phone uses ICS. Can anyone tell me what's going wrong?
