Not all unlocked phones are fully compatible with all networks. It’s common for a phone that’s not carrier-locked to be incompatible with certain networks or have sub-par performance due to compatibility issues.
On this page, I list devices that I believe have near-universal compatibility across U.S. wireless networks. The page is inspired by a similar list on PrepaidPhoneNews.com that seems to be falling out of date.
Please verify anything important before buying a device and be sure to pay attention to model numbers. Phones with the same names but different model numbers often have different radio hardware.
I consider a phone to have nearly universal compatibility if it meets the following criteria:
- Support for LTE bands 2, 4, 12, 13, 25, 41, and 71
- Support for UMTS at 850 and 1900 Mhz (bands 2 and 5),
- Support for CDMA at 850 and 1900 Mhz (BC0, BC1, and BC10)
- Whitelisting from Sprint (check IMEI numbers here)
- Expected VoLTE support on Verizon
Additional characteristics I track that may make a phone closer to fully universal include:
- Explicit whitelisting from Verizon (Android whitelist, Apple whitelist, IMEI check).
- Support for LTE bands 5, 26, 29, 30, and 66
The big, wonky Google Sheet I use for tracking devices and their characteristics is publicly available here. For more details about how carriers use different frequency bands, see this excellent article from PhoneArena.

In this article, I only assess the bands and frequencies that are important for accessing major networks in the U.S. Other bands and frequencies may be important in other countries.
Sprint, Verizon, and MVNOs running over those networks may be finicky about devices they allow. Dennis Bournique suggests the following:
- Sprint’s prepaid brands may have a more restrictive whitelist than Sprint itself. Virgin Mobile is especially restrictive, only allowing some iPhone models under it’s BYOD program. (Boost compatibility can be checked here. Virgin compatibility can be assessed here.)
- Verizon may block MVNOs using its network from activating devices that were last used directly on Verizon. (I’m unsure if this still happens or is common. I have not encountered this issue myself.)
In my article Phone Compatibility & Unlocking Explained, I go into more details about the factors that affect phones’ compatibility across networks. In another article, I summarize the major carriers policies around device locking and unlocking.
- You can check whether your phone is whitelisted by entering your IMEI here. As far as I know, Sprint no longer offers a text list of supported devices.
- VoLTE support is often difficult to verify, so I’m not always confident about my expectations around VoLTE support. Here are my impressions about VoLTE requirements by carrier:
- T-Mobile – According to Dennis Bournique, “VoLTE is required to make phone calls in band 12 and band 71 T-Mobile markets.”
- Verizon – Verizon will not activate devices that do not support HD Voice (a VoLTE technology)
- AT&T – In an October 2018 forum post, an AT&T employee stated the following: “VOLTE, WiFi calling, Video Calling, are luxuries essentially. Not having VOLTE doesn’t affect the ability to use the network for voice calls. It’s an enhanced feature for branded phones essentially.” I am not confident that this was true then or that it is still true now.
- Sprint – I am not aware of any requirements for VoLTE support on Sprint’s network.
- As of June 2019, I believe the Android list is out-of-date and may not include a handful of recently released phones that are whitelisted.
Non-whitelisted devices appear to work with Verizon, but that may not guarantee they will continue to work on Verizon’s network in the future.
- “Currently, Virgin Mobile only supports iPhones in its ‘Bring Your Own Device’ program.”
