T-Mobile USA Offering $50 Unlimited Nationwide Calling Plan

Sources close to T-Mobile USA said today that the company would be offering a $50 per month unlimited calling plan to long-time customers. This move comes as phone companies continue to compete to stay competitive in the price wars in the mobile phone industry.

Also under the same promotion, T-Mobile is offering customers a $135 credit for switching to T-Mobile from rival services.

The new unlimited plan will only be avaliable to customers who have had service for 22 months or more and you must live in the San Fransisco area during this limited trial. It's expected to be nationwide by end of March with a more formal announcement expected then.
