My phone (Samsung Galaxy Grand Prime) let's me send msgs to everyone. Everyone, that is, except for businesses. I'm talking about the ones with 5-6digits in their number. For example, AE and Ulta have both sent me msgs asking for permission to send me coupons etc via text ("Reply 'UlTAYES' to confirm" or "Reply 'YES' to confirm"). That's the only point where my phone has a problem. It won't let me send those msgs for confirmation. I've tried clearing the data in the Application Manager and turning it off. I don't know what the deal is. Any help would be appreciated. Thanks!
