Good ol’ Wally isn’t a stranger when it comes to offering prepaid wireless goods within its shops, and now the retail giant’s about to add yet another service to that carrier-packed inventory. Starting next month, US Cellular — in partnership with Alltel Wireless — will begin rolling out a new contract-free package dubbed “U Prepaid,” which, naturally, is set to be backed by both of the aforementioned carrier’s networks. The fresh U Prepaid deal will be making its way into “nearly” 500 Walmart stores across 18 US states, though there’s no mention of which ones specifically. That being said, US Cellular and Alltel did announce the four devices coming at launch, including Samsung’s Repp and Chrone along with the LG Attune / Exchange and Saber. In any case, now you know where to go if those recently announced plans from AT&T and Verizon aren’t keeping a smile on your face.
