A:Answer Absolutely! I use straighttalk which is owned by tracphone I believe. It takes about 24 hrs for everything to work properly but I used the unlocked model, I think straighttalk/tracphone has one available locked to their network that is instant correct APN settings out of the box. On the unlocked model, you have to modify your APN settings to work properly, I had to manually do it and once I was able to receive SMS straighttalk was able to fine tune my APN settings. Also when I first put in SIM, phone could send everything out going, I just wasn't getting anything back incoming till I made changes except calls where working correctly. Tip* If you have to look up APN guides online make sure to check the dates of publishing because there is A LOT of outdated APN data that gets frustrating because it comes up first on search engines.
