But tech blog Engadget spotted the fine print on T-Mobile's data plan, which showed that the carrier planned to throttle speeds for customers who used more than 1 GB of data.
After much criticism across the Web, the fourth-largest U.S. carrier removed the soft-cap wording from its monthly data plans Wednesday.
"We removed the 1 GB soft limit from our policy statement, and we are confident that T-Mobile G1 customers will enjoy the high speed of data access over our 3G network," T-Mobile said in a statement. "The specific terms for our new data plans are still being reviewed and once they are final we will be certain to share this broadly with current customers and potential new customers."
T-Mobile is finalizing terms for the monthly data plans, which will cost $25 and $35 depending on messaging options. The carrier hasn't dismissed the possibility of a soft cap, as the company's 3G network is still in the process of being rolled out.
"We have a responsibility to provide the best network experience for all of our customers so we reserve the right to temporarily reduce data throughput for a small fraction of our customers who have excessive or disproportionate usage that interferes with our network performance or our ability to provide quality service to all of our customers," the company said.
AT&T, Sprint, and Verizon Wireless also have soft caps on their 3G data plans, but these generally start at 5 GB a month. Customers who exceed these limits are normally charged extra fees, and it's likely that T-Mobile could mirror that policy.
