Spectrum is the real problem. There is just not enough space for 3-4 LTE providers in addition to all existing GSM/CDMA carriers. We are solving this problem in Russia too, but with a different solution. One carrier (Yota) is building a shared network of LTE base stations and allows all carriers to sell it. Other carriers have the option to buy 20% of Yota five years down the road. Also, Yota agrees to stop being a carrier itself by that time. It's like energy grid, GPS sattelites or highway system. You better have just one utility and regulate it well.
