The subject line says it all. I got a brand-new Motorola RAZR for my birthday, and it's locked to the Fido network. It's on a plan and it works fine, but text messages that are sent to me never appear in my inbox. I can send the text messages just fine, but the phone fails to recieve text messages. I hacked the phone to download games and a skin for free, but I haven't fiddled around with the firmware so I doubt that this is the problem. I already called Fido Tech Support, but their solution does not fix the problem. Any of you experience the same thing and know the remedy?
