AT&T Semi Premium Unlock - iPhone All Models Till 16 Pro Max
AT&T iPhone 16 Unlock — Fix “Carrier Blocking eSIM” on iPhone 16e, 16, 16 Plus, 16 Pro & 16 Pro Max
Travelling, moving abroad or switching networks, and your iPhone 16 says “SIM locked – contact your carrier” or that your carrier is blocking a new eSIM? We remove the AT&T carrier lock remotely by IMEI. After that, you can use any local or travel eSIM in any country, and the unlock is permanent.
About the AT&T USA iPhone 16 Series Unlock
Every iPhone 16 model sold in the United States, including the budget iPhone 16e, is eSIM-only. These phones support two active eSIMs and can store several more, which makes them excellent for international travel. When the phone is still locked to AT&T, though, that feature doesn’t work. A travel eSIM, a local operator’s eSIM or another US carrier’s eSIM is rejected with messages such as “Your carrier is blocking this eSIM”, “SIM locked – contact your carrier” or “eSIM not compatible”.
This service removes the AT&T carrier lock through the device IMEI. Once your order shows Success, Apple’s activation server lists the iPhone 16 as unlocked, and Settings > General > About > Carrier Lock shows “No SIM restrictions”. You can then add eSIMs from any carrier that supports iPhone, wherever you are.

Is Your iPhone 16 AT&T-Locked? Common Signs
The most common case: a travel data eSIM won’t install on an AT&T iPhone 16 Pro Max.
This appears after you land abroad and try to activate a local eSIM on an iPhone 16 or 16 Pro.
Dual eSIM is supported by the hardware, but the AT&T lock blocks the second carrier.
A US phone sold abroad can’t connect to any local network because it is still tied to AT&T.

How to Unlock an AT&T iPhone 16 by IMEI
Dial *#06# or check Settings > General > About.
Add funds, select “AT&T USA iPhone 16 Series” and enter the IMEI.
You are notified by email and in your dashboard.
Settings > Cellular > Add eSIM, then scan the QR code or use the eSIM app.
Still Seeing an Error After the Unlock?

AT&T iPhone 16 Unlock — FAQ
Why does my iPhone 16 say my carrier is blocking the eSIM?
Your iPhone 16 is carrier-locked to AT&T, so it only accepts AT&T-approved eSIMs. Removing the lock lets you install eSIMs from any provider.
Can I unlock my AT&T iPhone 16 while I’m abroad?
Yes. The unlock is done remotely by IMEI, so you can order from any country. Once it is completed, connect to Wi-Fi and install your local eSIM.
Is the iPhone 16e supported?
Yes. The AT&T iPhone 16e (A3212) is eSIM-only like the rest of the US iPhone 16 family, and it is fully supported.
Can I use a physical SIM card after unlocking a US iPhone 16?
No. US iPhone 16 models have no SIM tray. After the unlock, you can use eSIM from any carrier that supports iPhone.
Is the unlock permanent after iOS updates?
Yes. It is saved on Apple’s activation server and stays after updates, restores and resets.
Can you unlock a blacklisted or iCloud-locked iPhone 16?
No. Lost or stolen devices cannot be carrier-unlocked, and this service does not bypass iCloud Activation Lock.
