I have a pay as you go plan so I'm very limited in what I can do on it but I was able to download an app to block calls. If you can do that, try PhoneWarriors.
Received call in the 9 am hour Pacific Time. Hung up before I could answer, no message left. Other posters state caller is credit card scam type of call, glad I missed. I typically don't get these calls to my home, but frequent calls if this type to my cell lines.
Called. Didn't leave a voicemail message. I do not call back numbers that don't leave me a message unless I recognize the number and or left a message for me and that is important.
