Which companies use Verizon towers?
AT&T has Cricket, Sprint has Boost Mobile, T-Mobile has GoSmartMobile and Verizon has Total Wireless. The sub-brands use the same towers and systems as the major brands, but at a lower price and with no contract. Although you should check first, the parent network phone should be compatible with the sub-brand service.
Buy or Sell on Glyde
- Unlocked. Unlocked phones are compatible with GSM carriers like AT&T and T-Mobile as well as with services that run on GSM SIM cards.
- MVNOs. MVNOs or Mobile Virtual Network Operators are smaller carriers such as Cricket Wireless, Credo Mobile, Ting, and Red Pocket.
- Verizon is a CDMA carrier, and operates on a different technology than AT&T and T-Mobile (which are GSM). However, you should still be able to use your unlocked Verizon 4G LTE device on AT&T or T-Mobile, as most handsets will be compatible with both carriers' LTE bands.
- Which carriers are compatible with one another?
- CDMA Technology: Verizon and Sprint both run off CDMA technology. However, Verizon devices will not work with Sprint services and vice versa.
- GSM Technology: AT&T and T-mobile both run off GSM technology.
- Switching carriers - the carriers outside of the big four all run off one of the big four's networks.
- If you buy an iPhone from AT&T, it will be "locked" to AT&T's network. That means if you try to put in a T-Mobile SIM, it won't work. Same with an international SIM if you're traveling. Just because you're locked, though, doesn't mean you can't unlock.

- Answered: What Does Carrier TFW Stand For on Your Straight Talk Phone? It just occurred to me–Straight Talk's parent company is TracFone Wireless!! I.e, TFW. There you go, just in case you wanted to know, TFW stands for TracFone Wireless, the parent company of Straight Talk.
- It could, but typically, US carriers choose not to. Many Sprint and Verizon phones now have SIM cards, but that isn't because of CDMA. The SIM cards are there for Sprint's and Verizon's 4G LTE networks, because the LTE standard also uses SIM cards. (3G GSM is also actually a type of CDMA.
- After AT&T's merger with BellSouth Corporation, Consumer Cellular re-negotiated its contract with AT&T to allow national coverage through its network. In 2008, Consumer Cellular became a preferred provider for AARP members, making the company the first cell phone provider to market to retirees.
TracFone Wireless operates as a mobile virtual network operator (MVNO), holding agreements with the United States' largest wireless network operators to provide service using their networks, including Verizon Wireless, AT&T Mobility, T-Mobile US, Sprint Corporation, and U.S. Cellular.
- Straight Talk is a service provided by TracFone Wireless Inc., America's largest no-contract cell phone provider in the U.S., with over 25 million subscribers. TracFone Wireless is a subsidiary of América Móvil S.A.B. de C.V.
- Boost. It would be tempting, and not entirely wrong, to think of Boost Mobile as the Mini-Me to its parent company, Sprint. Boost uses Sprint's network and essentially offers the same performance. And like Sprint, Boost is pushing unlimited plans, though with a few more restrictions than what Sprint now offers.
- Both Tracfone and Verizon Wireless cell phones use a Subscriber Identity Module (SIM) card. This card lets you switch networks with ease. Tracfone will provide you with an unlock code. Once the phone is unlocked, you can have your phone flashed and activated to the Verizon Wireless network.
