Why Check SIM Lock & Carrier Before Buying?

A SIM-locked phone only works on one carrier network. If you buy a locked device without knowing, you won't be able to use it with your preferred carrier. Our free SIM Lock & Carrier Check reveals the exact carrier, lock status, and unlock eligibility — so you know exactly what you're buying.

Our iPhone Carrier Check is the most accurate tool available — it queries Apple's servers to return the original carrier name, country, and next tether activation policy. This tells you whether the iPhone can be unlocked and which network it belongs to.

For non-Apple devices, our Universal SIM Lock Check and Model Lookup identify the device and verify its lock status across global databases.

What You Get in the SIM Lock & Carrier Report

• Carrier Name & Country — Know exactly which carrier the phone is locked to (AT&T, T-Mobile, Vodafone, etc.) and the original country.
• SIM Lock Status — Locked, Unlocked, or Factory Unlocked — know before you buy.
• Next Tether Policy — Apple's activation policy reveals if the device can be unlocked or is permanently locked.
• Unlock Eligibility — Whether the device qualifies for carrier unlock or needs to be paid off first.
• Network Compatibility — Check which bands and networks the device supports.
• Device Model & Specs — Full model identification, manufacturer, and hardware details.

Buying a Phone? Check SIM Lock First

1. Check the carrier — A phone locked to AT&T won't work on T-Mobile (and vice versa). Verify carrier before buying.
2. Verify unlock status — "Unlocked" phones work on any carrier worldwide. Always confirm this with an IMEI check.
3. Check next tether policy — For iPhones, this Apple-specific policy reveals the true lock status and unlock eligibility.
4. Avoid financed devices — Phones with unpaid installments can be re-locked by the carrier at any time.
5. Test with your SIM — After checking online, insert your SIM card to physically verify compatibility.
