TracFone and its sister brands NET10, and Straight Talk, do not have their own networks. They're Mobile Virtual Network Operators (MVNOs) that buy wholesale minutes, texts and data from AT&T, T-Mobile, Verizon and over a dozen smaller regional networks. Straight Talk and Net10 also have smartphones that run on the T-Mobile, Verizon and AT&T networks. Each phone has a home network that's either AT&T, T-Mobile or Verizon. Years ago Straight Talk and Net10 some some phones homed on Sprint but those seem to be long gone from the distribution channels.
All three companies sell BYOP (Bring Your Own Phone) SIMs. SIMs for the AT&T, Verizon and T-Mobile networks are available from all three companies. Net10 and Straight Talk can also activate Sprint phones on the Sprint network but the user must supply their own Sprint SIM.
TracFone, Straight Talk and NET10 phones will favor their home network and refuse to roam in an area where the home network claims to have coverage. So if you have a phone whose home network is T-Mobile and you are in an area where T-Mobile has spotty coverage, the phone will refuse to roam on AT&T even if AT&T has a better signal. The Sprint based phones don't roam at all.
Which network a given TracFone, NET10 or Straight Talk phone is homed on depends on the market it's sold in. TracFone companies seem to prefer selling T-Mobile homed phones, followed by Verizon with AT&T as a last resort. I suspect this is because they get the best deals from T-Mobile and the worst from AT&T.
What's most cost effective for TracFone is not always what's best for you as the end user. Here's how to tell which network a given TracFone is homed on and how to get a phone that will give you the best coverage in the areas where you live, work and play.
Start by determining which of the three networks will give you the best coverage. If you have a TracFone, NET10 or Straight Talk phone that works well see below for how to find out what network it uses. Ask friends with prepaid phones what network they are using and how well it works. Look at the Verizon, AT&T and T-Mobile prepaid coverage maps to see each carrier's native coverage area (ignore areas labeled as "roaming" or "partner").
Once you know what home network you want, here's how to determine which phones work on that network.
The NET10, TracFone and Straight Talk iPhone 4, 4s and 5 use the Verizon network.
The current NET10, TracFone and Straight Talk iPhone 5s, SE, 6 and 7 come with Verizon SIMs but can be activated on AT&T uy using a Net10, Straight Talk or TracFone BYOP SIM

The Motorola V176, V170 and C139 and LG225 are also GSM phones that can be on either T-Mobile or AT&T.
To tell if a GSM phone is homed on T-Mobile or AT&T:
If you are buying the phone in a store look for the product number on the box under the barcode. If it ends in P4, R4, AL or P4P, like TFLG800GTMP4P it's AT&T. If it ends in P5, R5, TL or P5P like TFLG800GTMP5 it's T-Mobile.
Most Tracfone, NET10 and Straight Talk phones also have a network code on the box. It's usually in the lower left corner on the front of the box. These codes are: CDMA-V or LTE-V = Verizon, GSM-A or LTE-A = AT&T, GSM-T or LTE-T = T-Mobile.
If you already have the phone, check the SIM ID printed on the SIM and shown in the Prepaid menu (feature phones only). The first six numbers of the ID determine the carrier: 890126 = T-Mobile, 890141 = AT&T, 891480 = Verizon.
Or look at the SIM itself. AT&T Tracfone SIMs have a code on them that includes the sequence SIMC4, like TF64SIMC4. If the SIM has a code containing SIMT5, like TF128SIMT5, it's for T-Mobile. Verizon SIMs codes contain SIMV9 like TF256PSIMV9DD
If you are ordering a phone online from NET10, after you enter you zip code look at the page URL for a string of characters beginning with &market=. The 4-6 characters after the "=" are the TracFone Market codes. Decode them as follows:
GSM4 = AT&T
GSM4SPR = AT&T or Sprint (Net10/Straight Talk Only)
GSM5 = T-Mobile
GSM5AT = T-Mobile or AT&T
GSM5SPR = T-Mobile or Sprint (Net10/Straight Talk Only)
CO = Verizon
COGSM4 = Verizon or AT&T
COGSM5 = Verizon or T-Mobile
COSPR = Verizon or Sprint (Net10/Straight Talk Only)
For example, the URL; http://www.net10-store.com/bpdirect/tracfone/Start.do?action=view&market=GSM5AT&aid=&vid=&vc=&sahcid=&com=&zip=94132&locale=en&siteType=TR&gotoPhonelist=true&AID=
Contains "&market=GSM5AT" so it's a market in which both T-Mobile and AT&T will work. TracFone almost always sells T-Mobile phones in GSM5AT or COGSM5 markets.
If your zipcode gives you a T-Mobile or Sprint market and you know AT&T or Verizon works better for you then:
- For NET10 go to www.net10.com/store_manager.jsp?task=buyphone
- For Straight Talk go to shop.straighttalk.com/shop/en/straighttalk/phones
- For TracFone go to shop.tracfone.com/shop/en/tracfonestore/phones
- When prompted to enter your zipcode use 65046 (Jamestown MO) or 76825 (Brady TX) for AT&T or 73949 (Texhoma OK) for Verizon
- After entering one of the zipcodes and clicking OK and amswer Yes to the "phone will be used in..." prompt. Fot Net10 only you can verify that the URL of the page listing the available phones contains "&market=GSM4" for AT&T or "&market=CO" for Verizon. If it doesn't don't order the phone, as you probably won't get what you want. Please leave a comment if one of the zipcodes stops working so I can update the post.
- Be sure to change the zip code back to yours in the address field on the shopping cart page. Regardless of what market a phone was sold for you will get a number local to wherever you activate the phone.
- An alternate way to get what you want on Net10 is to enter your own zipcode at the initial prompt and then edit the URL of the page showing the available phone. You need to change whatever is between &market= and the next & to the market you want; CO for Verizon, GSM4 for AT&T or GSM5 for T-Mobile. For example, if the phone's page URL contains &market=GSM5SPRCO& and you want to see only AT&T phones, replace &market=GSM5SPRCO& with &market=GSM4& and press the Enter key. The page will reload showing only AT&T network phones. This trick only works on Net10.
Before using a different zipcode or the URL edit trick to get the phone or network you want be sure to check the Verizon, AT&T or T-Mobile coverage map to verify that the phone's home operator has coverage where you will be activating the phone. Phones will not activate in an area where their home operator doesn't have coverage.
