Just wondering if anyone is having similar issues. Every now and then when I send a text to someone from my contacts I get a text telling me I have to use a valid 10 digit number. But when I check the contact it shows that it is a 10 digit number. I have tried deleting the contact and reentering it but still the same thing. This has only happened to about 7 of my contacts. Any thoughts? Thanks and sorry if this isn't the right section for this.
