Permanently unlock your carrier-locked Apple iPhone 18 series handset from AT&T USA using our official Semi-Premium server service on GrandUnlock. This cost-effective server solution submits your IMEI directly to AT&T and Apple GSX database queues, permanently whitelisting your device for open connectivity across any GSM, LTE, or 5G carrier worldwide.

- Supported Carrier: AT&T USA (Original Network Lock)
- Supported Device Scope: Apple iPhone 18 series (iPhone 18, 18 Plus, 18 Pro, and 18 Pro Max)
- Service Standard: Semi-Premium tier offering high success rates at an optimized price point for qualified accounts
- Unlock Permanence: 100% permanent Apple GSX factory whitelisting—freely update iOS firmware, perform full iTunes/Finder restores, and switch network carriers without relocking

Important Service Requirements & Verification Rules:
1. 14-Day Activation Rule: The handset MUST have been activated on the AT&T network for a minimum of 14 days prior to submission. Unactivated or newly opened out-of-the-box units will be rejected by the server.
2. Clean Status Only: Strictly intended for clean IMEI records with clear policy standing. Devices reported lost, stolen, or flagged on carrier blacklists are not supported.
3. Carrier Confirmation: Confirm your device is locked strictly to AT&T USA (run an Apple GSX Carrier Check beforehand if uncertain).
4. iCloud Status: This service removes network carrier SIM restrictions only; it does not bypass or remove iCloud / Find My iPhone (FMI) activation locks.

How to Order & Complete Activation:
1. Dial *#06# on your iPhone 18 to retrieve your 15-digit IMEI number.
2. Enter the IMEI into the required order box on GrandUnlock.
3. Complete checkout and monitor your dashboard for the "Completed / Unlocked" status update.
4. Once completed, connect the iPhone to a stable Wi-Fi network with a non-AT&T SIM inserted (or scan an eSIM QR code) to trigger automatic over-the-air activation.
