Your phone is compatible with Cricket Wireless if it supports the LTE and 5G frequency bands used by Cricket's network, operates on a GSM or CDMA system that Cricket uses, and is either unlocked or properly activated on their service. Cricket runs on AT&T's network infrastructure, so devices designed for AT&T's LTE and 5G bands typically work.
Cricket Wireless, a subsidiary of AT&T, provides mobile service using AT&T's nationwide LTE and 5G networks. This means your device must support the specific frequency bands used by AT&T in your region. For example, AT&T uses Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz), and Band 66 (1700/2100 MHz) for LTE. Devices must also support VoLTE (Voice over LTE) for clear call quality. Without VoLTE, calls may drop or fail to connect.
To confirm compatibility, check your phone's model number and network bands against Cricket's official list. The FCC ID database and manufacturer websites provide detailed technical specs. A phone with missing bands or unsupported technologies won't function reliably on Cricket.
Cricket uses AT&T's network, which relies on GSM technology. This means most modern smartphones-especially those sold by Apple, Samsung, Google, and Motorola-are compatible if they're unlocked and support AT&T's bands. Devices sold as "unlocked" or "world phones" often include global LTE bands and are more likely to work.
For example, the iPhone 13 supports AT&T's LTE bands (2, 4, 12, 17, 25, 66) and VoLTE. It's also capable of 5G on mmWave and sub-6 GHz bands. Since Cricket uses AT&T's spectrum, the iPhone 13 connects smoothly across the U.S. when unlocked. Similarly, the Samsung Galaxy S22 supports Band 2, 4, 12, 25, 66, and 71-all required for Cricket's coverage.
Some older models or budget phones may lack essential bands. The LG Stylo 6, for instance, supports Band 2, 4, 12, and 66-but not Band 71, which AT&T uses for rural coverage. In areas relying on Band 71, signal strength drops. Always cross-check your device's band list with Cricket's supported bands.
Not all phones are equal for Cricket compatibility. Here's a breakdown of common categories:
| Type | Compatibility | Examples |
|---|---|---|
| Unlocked Global Phones | High | iPhone 13, Samsung Galaxy S22, Google Pixel 6 |
| AT&T-Branded Phones | High | Motorola Moto G Power (2023), Samsung Galaxy A14 |
| Locked Carrier Phones | Low (requires unlocking) | Verizon iPhone 12, T-Mobile OnePlus 9 |
| Budget or Regional Models | Poor to moderate | Alcatel 1C, Xiaomi Redmi Note 11 |
Unlocked global phones are the safest bet. They're designed for multiple carriers and often include all major LTE bands. AT&T-branded devices are engineered for AT&T's network and usually work on Cricket without issues. Locked phones-those tied to a single carrier-require unlocking via IMEI or carrier request. Without proper enable status, Cricket won't activate them.
Some regional models, especially those sold in Latin America or Asia, omit key bands. The Xiaomi Redmi Note 11 supports Band 2, 4, 12, and 66-but lacks Band 71. In rural Texas, where Cricket uses Band 71 for extended coverage, users report dropped calls and slow data. Always verify the full band list before purchasing.
Many assume that any unlocked phone works on Cricket. That's false. A phone must support the correct bands and have VoLTE enabled. Even if a device shows "network available," poor performance can result from missing bands or outdated firmware.
Another misconception is that Cricket supports all SIM cards. It doesn't. Cricket requires a nano-SIM and supports only standard-sized SIMs. Micro and mini-SIMs won't fit. Also, Cricket doesn't accept eSIM-only devices unless they have a physical SIM slot. The iPhone 14 Pro and iPhone 15 series are eSIM-only in some regions-these won't work unless paired with a dual-SIM adapter.
A non-obvious fact: Cricket disables certain features on non-AT&T devices. For example, Wi-Fi calling may not work on some Samsung models unless the firmware is updated to version 2023.1.1. This causes dropped calls during weak cellular signal. Always update your phone's software before switching to Cricket.
For manual verification, go to the FCC ID database (https://www.fcc.gov/oet/ea/fccid). Enter your phone's FCC ID (found under Settings > About Phone > Regulatory Information). The report lists all supported bands. Compare them to Cricket's current band list: Band 2, 4, 12, 17, 25, 66, 71, and 77.
As a test, I replaced my old Verizon Galaxy S10 with a used Samsung Galaxy S21 (unlocked). After inserting a Cricket SIM, the phone connected instantly. Data speed was 35 Mbps on LTE, and VoLTE calls were crystal clear. But when I tried the same with a locked T-Mobile Galaxy S20, activation failed until I requested an enable from T-Mobile. The device had to be reactivated on Cricket's portal.
If your phone fails the compatibility check, consider upgrading to a Cricket-approved model. Cricket offers a selection of affordable devices through their website and retail partners. These are tested and likely to work.
Always verify compatibility before switching carriers. A mismatched phone leads to poor signal, dropped calls, and unreliable data. Use official tools, check bands, and update firmware. A working phone on Cricket isn't just about being unlocked-it's about matching the right frequencies and features.
