TracFone SIM Card Questions Answered

I get a fair amount of questions regarding TracFone and Net10 SIM cards. Here are some of the most common questions I hear:

  • What kind of info is stored on my SIM card?
  • I just bought a new phone. Can I just switch the SIM card from my old phone into my new phone, and be ready to use the new one?
  • Can I use an unlocked phone with TracFone service?
  • What do the numbers on my SIM card mean?

I’ve come across a web page that does a good job of answering those and other questions about SIM cards, and provides some more technical info about TracFone in general. Even if you don’t have any of those questions now, you might want to check out this page:

Hopefully you will find it informative, and maybe it will save you some headaches in the future.

  1. This is one of the most asked questions about Tracfone SIM cards. Tracfone is the only cell phone provider that actually locks the SIM card to the phone that they are activated in. It is part of the proprietary software Tracfone developed to show the minutes on your phone all the time. Now the Verizon phones show how many minutes all the time also.

  2. i would like to know if i can talk to a someone that has knowledge of how cell phones work. especialy TRACFONE and voice mail plans thru ATT.
    thank you for ur time

  3. i i have my straight talk phone sims card and put it in the unlocked e71 nokia will it work because straight talk has this phone but im not buying it from them will it work???

  4. Hi Rose
    Unfortunately this will not work. The E71 will have to be purchased from Straight Talk in order for it to work, at least as far as I know. Other people have done some testing of similar SIM swapping without success. I think the basic reason for this is that Straight Talk will only activate phones that are in their database of eligible handsets. This is tracked by ESN. So your plan would not work. Further, I believe that once activated, the Straight Talk SIM will be locked to the phone in which it was activated.

    If you decide to take your chances and test it out, though, please let me know how it turns out!
