Apple iPhone 6s Carrier Unlock Guide
Introduced in 2015, the iPhone 6s can be identified using Apple’s official A-number list. Its carrier unlock is applied by the current carrier through Apple’s activation system, not by a calculated code.
GetMyUnlock helps you find the legitimate free method. Only the original carrier or an authorized provider can issue a numerical network code when one is actually required.
Quick answer
Apple does not unlock an iPhone for another carrier and modern iPhones do not use a generated network-unlock code. The current carrier must approve and apply the unlock through Apple’s activation system.

Check the carrier-lock status
On supported iOS versions, open Settings → General → About and check Carrier Lock. “No SIM restrictions” indicates that the iPhone is unlocked.
How unlocking works on this phone
This device is normally unlocked remotely after the original carrier approves the request. It does not need a calculated code.
SIM details
Apple documents a physical nano-SIM tray for this model. SIM configuration can still vary in China mainland, Hong Kong, and Macao, so confirm the A-number.
eSIM details
Apple’s identification documentation shows a physical nano-SIM tray for this generation; it predates iPhone eSIM support.
Find the IMEI safely
Dial *#06# on many phones or use the device settings. Keep the full 15-digit number private. This public page does not need it, and it should only be entered in a carrier's official form or GetMyUnlock's private checker.
Test with another SIM
After approval, connect to Wi-Fi, restart when instructed, then test a compatible SIM or eSIM from another carrier. Unlocking does not guarantee radio-band, eSIM, or plan compatibility with the destination network.
Request a legitimate carrier unlock
- Identify the original carrier and exact device variant.
- Resolve applicable financing or contract obligations.
- Confirm the device is not reported lost, stolen, or associated with fraud.
- Meet the carrier's activation and service-period rules.
- Submit through the carrier's current official website, app, store, or support channel.
If the unlock request fails
Confirm the exact model, original carrier, account eligibility, financing status, and the carrier's instructions. Do not repeatedly guess codes—too many incorrect attempts can cause additional restrictions.

Frequently asked questions
Is there a free unlock code for the iPhone 6s?
The original carrier may unlock an eligible phone without an additional unlocking charge. Many modern phones are unlocked remotely and never use a numerical code. If a code is required, it must come from the carrier or an authorized provider.
Can the iPhone 6s be carrier unlocked?
It may be eligible, but the original carrier decides based on its current policy, the account, financing, activation period, and lost or stolen status.
Will a network unlock erase my data?
A normal carrier unlock should not erase personal data, but you should always keep a current backup before changing SIMs or device settings.
Does this remove Activation Lock or a screen passcode?
No. A carrier or network unlock is separate from screen locks, iCloud Activation Lock, and Google Factory Reset Protection.
