Turned on my cell and the same phone number was there - I missed the call - thank goodness. Thanks for giving me a heads up. I have disabled my text messaging so that is probably why I didn't get a message.
I visited Wal-Mart website looking for something and then got the text form 408-520-8475 and telling me to call 877-861-8581 to claim $100 gift card from Wal-Mart so somehow someone is intercepting and getting e-mail address when you visit Wal-Mart Web Site.
I work for the company with which this prepaid number was held. I have since disconnected the number from the network, so you should not be receiving any more messages from this phone.
