Following AT&T’s lead, T-Mobile will soon be offering new 5GB and 10GB data plans for a limited time. In a purported internal memo acquired by TmoNews, the carrier will begin offering the new plans starting January 25th. The Unlimited-Premium 5GB and Unlimited-Ultra 10GB plans will both include a free mobile hotspot and cloud storage, which normally costs $20 per month. The promo will be available to both new and existing customers, however the memo states that in order “to protect T-Mobile revenue” reps should “not proactively offer the bundled features to customers already on a 5 GB data feature who do not want additional data.”
