I received a text message requesting a response code from this number. ID said that is was Whatsapp.com, which I have never used or signed up for. Shortly after that I received a phone call from the same telephone number which I did not answer. I am very suspicious about phone numbers I do not recognize. If it is really important, it will go over to voice mail. This one I did not answer. Reading some other posts, I saw that this is a possible spam that responded to would allow malware to get into your cell phone to steal information.
This morning I have gotten 3 calls from this number in 3 minutes. It is a recording and in a foreign language I cannot identify. It does not appear to asian, arabic or african. I cannot place any sort of dialect.
