So I purchased a US Cellular branded phone off eBay(last time I do that). it had a clean MEID and the store put the SIM card in. The worker called *228 to activate and Verizon's programming line picked up instead of US Cellular's. I was not roaming and should have had great access to 4G. The seller is being uncooperative abd saying he did nothing and it isn't possible to flash or unlock a US Cellular phone. Does anyone have a clue how to fix this?
