Because t-mobile stinks for one, and two when a larger company ie T-mobile buys/merges with a smaller company ie Metro pcs, the smaller company dissolves over time. T-mobile is a contract provider, they have their own small "prepaid" that stinks, Metro Pcs is really the only one of its kind, its no contract but yet somewhat larger then other "prepaid" carriers. Its the only no contract carrier that has true 4g lte, T-mobile a contract carrier doesn't even have 4g lte yet. Prices are going to rise, the conversion of the networks is going to bottle neck the speeds. I don't see anything good in this merger for metro users.
People are saying oh metro will have better phones. HAVE YOU PEOPLE LOOKED AT THE PREPAID PHONES THESE CONTRACT CARRIERS OFFER? they suck. Most of them are worst than what metro pcs carries. Hell we are getting the SGS3. I don't see that on any of the list of prepaid phones.
