Bought a new v3xx that was unlocked (not from a dealer so taking back is not an option). It is branded ATT Singular. Works fine with my Cellular One sim card, around here. Whenever I travel outside my service area, signal is gone, no roaming, no anything. I haven't had this problem in the past when switching sim card from phone to phone.
Have tried reading through other posts and tried changing network menu options, but there aren't any. I'm trying : Main menu > Settings > Network >, but in there I only have two options, " Service tone & Call drop tone". Should there be other options there? How can I open these options up to search for other towers?
Any help appreciated. Thanks. Also, I live in southern Ky if relevant.
Hey! I wish I had the answer for you because I have same issue. I bought an ATT and paid to have it unlocked because Tmobile doesn't have RAZRs available any more. I use a Tmob SIM and it works fine... til I visit my friend in Chino VAlley, AZ. I know there is coverage out hter because my cowboy friend had Tmobile and it worked fine when he went to his family's ranch out there.
You think it's because it's unlocked it gets poor reception?
