Tmobile is experiencing "service interruptions" in all markets. Calls from some T-Mobile phones as well as the news coverage,  confirm that there is a problem. Some customers may have signal bars, calls from their phones usually result in a busy signal or a disconnection. Nothing is posted on tmobile.com or mytmobile.com, however they are nice enough to provide a LINK on how to report outages or service disruptions.
