T-Mobile and Walmart add new $45 unlimited plan, with a catch

. T-Mobile and Walmart announced on Tuesday that the Walmart Family Mobile plan now offers unlimited talk, text and web for $45 per month. Additional lines cost just $35 per month. Until Tuesday, Walmart's plan did not offer unlimited web access, but there's a big catch: the unlimited data doesn't always provide 3G data speeds. Instead, those who sign up before March 16th will be able to consume up to 5GB of data at 3G speeds. After March 31st, however, new customers will only be able to surf at 3G speeds for the first 250MB. Customers interested in purchasing the plan can do so in any nationwide Walmart store or by visiting Walmart.com.
