And most locked down networks? Virgin, Trac and Net10. No outside phone on their network and their phones are hard to get on other networks?
Worst coverage: Most mom and pop regional unlimiteds (Frawg wireless, Revol, etc.)
Most confusing naming scheme for an mvno: Locus. They have two billion subbrands of gsm and H2O cdma. Now they have an unlimited gsm name that uses the cdma brand name! lol
