**Reasons Why a Device May Be Restricted to the Original Carrier:**
* **Network Compatibility:** Carriers use specific frequencies and network technologies, so devices may be optimized for the networks of their original carrier.
* **Device Subsidies:** Carriers often subsidize the cost of devices in exchange for a contract, which may restrict the device to their network.
* **Software Customization:** Carriers may modify the software on devices to enhance their own services or restrict access to other networks.
* **Branding and Marketing:** Carriers may brand devices with their logos and lock them to their networks to promote brand loyalty.
* **Anti-Theft Measures:** Carriers may restrict devices to their networks to deter theft and unauthorized resale.
**Consequences of Device Restriction:**
* **Network Limitations:** The device can only be used on the original carrier’s network, limiting connectivity and roaming options.
* **SIM Lock:** The device may be SIM-locked, preventing you from using a SIM card from another carrier.
* **Software Updates:** You may not receive software updates from the manufacturer or carrier if the device is not unlocked.
* **Resale Value:** Restricted devices have limited resale value since they cannot be easily used with other carriers.
**Options to Remove Device Restriction:**
* **Carrier Unlocking:** Contact your original carrier and request an unlock code or pay a fee to unlock the device.
* **Third-Party Unlocking Services:** Use a third-party service to unlock the device, but be aware that these services may not be reliable or legal.
* **Factory Reset:** Attempting a factory reset may remove the network restriction in some cases, but this is not guaranteed.
* **IMEI Changing:** This is an advanced and illegal method that involves changing the device’s unique identifier (IMEI), which can potentially bypass network restrictions.

This device might be restricted to the or… – Apple Community Apr 21, 2022Yu Teng l. Settings -> General -> About -> Carrier Lock: SIM locked. Clicking into it it says “This device might be restricted to the original carrier and/or have certain capabilities limited. Contact your provider for more info”. The seller told me it’s because the phone was unused for 90 days so there is a temporary lock.
