Cricket Wireless Compatibility in the U.S.: 15 Digits Aren’t Enough
Run Cricket’s IMEI compatibility checker with your phone’s 15-digit IMEI, which you can pull up by dialing *#06#. If it says compatible and your phone is unlocked, you can activate. A 5G label does not guarantee Cricket 5G, because a phone missing the right bands falls back to LTE. Activate with a Cricket SIM or an eSIM on an eligible plan.
TL;DR:
- Cricket’s checker may omit some models, so contact support with the IMEI before rejecting an unlisted phone; first recheck its digits and exact model.
- Cricket requires a phone to be fully unlocked, paid in full, and not reported lost or stolen; unlocking alone does not ensure compatible radio hardware.
- An unlocked 5G phone can still fall back to LTE if its exact model lacks AT&T and Cricket bands or 5G coverage is unavailable nearby.
- If calls work but mobile data or picture messages fail, check Cricket’s APN, MMSC, MMS proxy, MCC, and MNC values, then restart the phone.

How do you find your IMEI and run the compatibility check?
Cricket says the most reliable pre-activation step is its own checker, and that you need the 15-digit IMEI to use it. Cricket’s BYOD guidance also states that a brought device must be unlocked and HD Voice capable. Here is the workflow:
- Open your phone’s dialer and enter *#06#. The IMEI appears on screen.
- On an iPhone, you can also go to Settings > General > About and scroll to IMEI.
- On Android, go to Settings > About phone and look for IMEI, which may sit under a Status submenu.
- Open Cricket’s online compatibility checker and enter the number exactly.
- Read the result and act on it.
The result usually falls into one of these categories:
- Compatible: you can move on to buying a SIM or setting up an eSIM.
- Incompatible: recheck the digits, the model number and the unlock status before giving up.
- Needs clarification on SIM type: the device may support eSIM, a physical SIM, or both, so confirm which one you will use.
If the phone has no IMEI at all, treat it as unusable. If you do not have the phone in hand yet, ask the seller for the IMEI in writing, or look on the retail box and receipt.
Pro Tip: Cricket’s own notes say the checker may not list every device, so a missing model is a reason to ask support, not proof the phone fails.
What does “unlocked” actually mean for Cricket?
An unlocked phone is not tied to one carrier’s network, so it accepts a SIM from any compatible provider. The simplest test is to insert another carrier’s SIM and see whether it gets service. You can also ask your original carrier to confirm the lock status.
Cricket’s guidance is blunt: a common pitfall is a phone that is still carrier-locked, and the device must be fully unlocked, paid in full and not reported lost or stolen. Carriers typically ask for the same before they will release a lock. Unlocking is only half the story, though. The FCC explains that unlocking enables carrier mobility but does not guarantee technical compatibility, since carriers use different frequency bands and radio technologies.
Keep these blocks in mind:
- A phone reported lost or stolen can be blacklisted and refused on any carrier.
- A phone with an unpaid balance may be locked by its original carrier.
- A phone built with incompatible network hardware can fail even when fully unlocked.
Why isn’t a 5G label a guarantee on Cricket?
Not every 5G phone carries the same radio bands. Cricket notes that not all 5G devices will have access to Cricket 5G, and an unlocked 5G phone may only connect on LTE if it lacks the specific bands used by AT&T and Cricket. Early 5G models and region-specific versions are the likeliest to fall short.
The FCC says 5G needs compatible hardware and band support, and that 5G devices are backward compatible with earlier networks. So the phone still works, just on LTE.
Before you buy, do this:
- Find the band list in the manufacturer’s spec sheet for your exact model number.
- Compare it with the bands AT&T and Cricket use.
- Confirm Cricket 5G coverage at your ZIP code, since 5G is not available everywhere.
On LTE, you still get calls, texts and data. What you lose is the faster 5G speed tier. For a broader walkthrough, see our guide on 5G compatibility checks.

Does eSIM or a physical SIM make activation easier?
eSIM is usually quicker. Cricket says eSIM-capable devices often activate faster, and that iPhone models from the XS onward and many recent Samsung and Google Pixel phones support it. You skip waiting for a mailed card.
How to tell if your phone supports eSIM:
- On iPhone, look under Settings > Cellular for an Add eSIM or Digital SIM option.
- On Android, check Settings > About phone for an EID number.
- If neither appears, assume you need a physical SIM.
With a physical SIM, order the Cricket SIM, insert it, and install any software update the phone prompts for.
Pro Tip: Keep Wi-Fi on during eSIM setup, since the profile downloads over the internet.
How do you restore data and MMS with APN settings?
If calls work but data or picture messages do not, your Access Point Name may need a check. Cricket publishes the values on its Android support page, and the fields to confirm are APN, MMSC, MMS proxy, MCC and MNC.
- On Android, open Settings > Network & internet > SIMs > Access Point Names.
- Edit or add the Cricket entry and match each field to Cricket’s published values.
- Save, select that APN, and restart the phone.
- On iPhone, confirm MMS and cellular data are on, and install any carrier settings update that appears.
- If it still fails, reset network settings and try again.
What should you do when activation goes wrong?
Most problems have a short fix:
- IMEI says incompatible: recheck the digits, the exact model number and the blacklist status.
- Calls and texts work, data does not: reinsert the SIM, reset network settings, then update the APN.
- No 5G icon: verify band support and Cricket 5G coverage in your ZIP code.
- Service drops outside town: Cricket does not charge extra for domestic roaming, so partner networks may carry you at no added cost.
Pro Tip: Write down the IMEI, SIM number and exact error before you contact support. It shortens the call.
Why do verified unlocked phones cause fewer surprises?
Most BYOD headaches come from unknowns: a hidden lock, a blacklisted IMEI, a model sold for another region. A phone sold with its unlock status and IMEI disclosed removes most of those unknowns before you pay. Less time troubleshooting means a smoother switch.

FAQ
Does Cricket charge for data roaming?
No. Cricket does not charge extra for domestic roaming. When its own network is unavailable, your phone may use partner networks across the continental U.S., Puerto Rico and the U.S. Virgin Islands.
What carrier does Cricket Wireless run on?
Cricket runs on AT&T’s network, which is why band support matters. Our AT&T unlocked checklist covers the same checks you will need for Cricket.
Can Cricket users use AT&T phones?
Often yes, if the phone is unlocked and passes the IMEI check. An AT&T phone that is still locked must be unlocked first.
Is my phone compatible with Cricket if the checker does not list it?
Not necessarily incompatible. Cricket’s BYOD page says the checker may not list every device, so contact support with your IMEI before assuming the worst.
