The second development coverage-wise: they've contracted with a bevy of other unlimited carriers (MetroPCS...and apparently Pocket...included) to provide unlimited-use roaming coverage in a ton of markets. The usage is voice-only, and you can't buy a CricKet phone and activate it in one of the roaming areas, but it's a nice bonus for areas in whihc Cricket has less than stellar coverage (ahem, Fredericksburg, TX).
Note that CricKet's ew home area coverage is available for PayGO (overpriced prepaid) customers, but the extended-area unlimited coverage is not.
Also note that MetroPCS did this earlier, and that one of CricKet's unlimited-minutes (no texting or data) roaming partners is in fact MetroPCS, thanks to the agreement they made recently.
If you're wondering about what the new roaming policies can do for you, check CricKet's new coverage maps out here. Hopefully i'll be able to post back with details on exactly who is provising CricKet with "PEC" (Premium extended Coverage), so you know exactly which fourteen coverage maps you should look at to get a better idea of where you'll be having service now.
UPDATE 1: I've narrowed down the unlimited provider in Kansas to NexTech Wireless. Also, I'm 99.9% sure that Pocket is a roaming partner. With metroPCS, we're up to three out of the fourteen roaming partners present and accounted for. If you have any ideas as to the other eleven, post a comment!
