I stopped putting my phone number in any ads. When I did I received texts non stop and at all hours. All scammers. I`ve been told that if you open a text there could be a virus attached to it. I use the cheap flip phones and had one of them hacked and ruined. At least that`s what my carrier said. If someone is serious about your item for sale they will send their number. If they are a buyer they will answer when you call. If they don`t answer don`t waste your time by calling again.
