All cricket phones I have had in the past have deadzones in Tucson, AZ. I get 1 bar, or no coverage in ANY of the following buildings: Walmart Target Kmart Government Buildings (Schools, Social Security Office, DES, etc.) Certain types of houses. (generally the further east, the worse off.) Also for those familiar with Tucson, anywhere east of Wilmot RD I get increasingly lower and lower service until around Houghton where I lose the signal entirely, plus anywhere east of there I have no service (Sierra Vista, for example.) My main concern for keeping my existing service is: Are my deadzones phone specific? If I buy a LG Optimus C, will I have deadzones in the same place? I am going to be a dorm student for the next year in a current deadzone and if Cricket has problems with this area, and Virgin Mobile doesn't, is it worth keeping the Cricket service for the insurance (only reason I'm even debating this lolz.) If I'm unable to use my phone in the building, I don't think the phone insurance will be worth only being able to use my phone after 4 PM, but only until 10 PM (curfew.) Someone please let me know if they have experienced similar problems, and if the LG Optimus C will have the same problems as other cricket phones I have owned.
