The phrase "support change imei at command" refers to cellular hardware (modems, routers, or smartphones) that allows users to modify the International Mobile Equipment Identity (IMEI) through standard serial AT commands. This capability is highly sought after in developer communities for hardware testing, network simulation, and privacy-focused use cases.

Core Technical Meaning

The most common command for this function is `AT+EGMR=1,7,"[NEW_IMEI]"`.

* Chipset Dependency: This specific command is natively associated with MediaTek (MTK) chipsets. Qualcomm devices typically use different proprietary protocols (like Diag Mode/QPST) rather than simple AT commands for IMEI management. WondershareGithub

* Application: It is frequently used on OpenWrt routers and M.2/Mini PCIe cellular modules to "repair" an IMEI or match a specific device's identity to bypass carrier restrictions (e.g., using a phone SIM in a dedicated router). Reddit

Product Trends & Insights

* The "Grey Market" Niche: There is a growing market for 4G/5G modems and routers explicitly marketed with "Custom Software" or "IMEI Change Support." These products often feature unlocked firmware to bypass the security locks imposed by major OEMs. AlibabaAlibaba

* Developer Focus: Modules from brands like Quectel and SIMCom are popular because they offer extensive AT command documentation, though official firmware rarely supports IMEI modification due to legal compliance. QuectelAlibaba

* Carrier Detection: Modern network operators use advanced "IMEI-TAC" database lookups. If a changed IMEI belongs to a different device category (e.g., using a phone IMEI on a industrial router), the carrier can automatically flag or block the connection. Alibaba

Market & Legal Landscape

* Legality: In many jurisdictions, including the UK (Mobile Telephones Act 2002) and the US (Wireless Telephone Protection Act 1998), changing an IMEI with intent to defraud or bypass detection is illegal. It is generally tolerated for private R&D or "IMEI Repair" of damaged NVRAM, but remains a high-risk activity. YcombinatorUsmile

* Security Risks: Many tools or firmware versions that enable "Easy IMEI Change" require Root access, which can strip away critical OS security layers and leave devices vulnerable to malware. Alibaba

Before running the command, I suggest that you write down your factory IMEI and keep it somewhere safe as there is no way to automatically reset the IMEI back to the factory default. Log into your X3000's GUI. On the main dashboard, select the Modem Management button (wrench+screwdriver icon) in the upper-right corner of the cell status, change "Shortcut" to Manual command and enter the following into the "AT command" box: I had to go to Manual Setup at the bottom section and change the APN to the carrier correct APN. Specifically speaking, I have AT&T using a sim from an ipad im paying for. I matched the IMEI from the ipad using the above command and changed the APN under manual setup to “BROADBAND” and it immediately connected and has been working flawlessly since. I just received my GL-X3000 and I'm also dealing with an error message when I apply AT+EGMR=1,7,"123456789012345” . The IMEI in that command has been changed to my current hotspot's, but the GL-X3000 won't accept it (error message) after many attempts and resets. Its extrodinarily simple - a single AT command will change the IMEI permanently.

SMS Tutorial: Introduction to AT Commands, Basic Commands and ...

www.developershome.com

Get basic information about the mobile phone or GSM/GPRS modem. For example, name of manufacturer (AT+CGMI), model number (AT+CGMM), IMEI number (International Mobile Equipment Identity) (AT+CGSN) and software version (AT+CGMR). That's why modem commands are called AT commands. Many of the commands that are used to control wired dial-up modems, such as ATD (Dial), ATA (Answer), ATH (Hook control) and ATO (Return to online data state), are also supported by GSM/GPRS modems and mobile phones. Besides this common AT command set, GSM/GPRS modems and mobile phones support an AT command set that is specific to the GSM technology, which includes SMS-related commands like AT+CMGS (Send SMS message), AT+CMSS (Send SMS message from storage), AT+CMGL (List SMS messages) and AT+CMGR (Read SMS messages). In addition, some AT commands require the support of mobile network operators. For example, SMS over GPRS can be enabled on some GPRS mobile phones and GPRS modems with the +CGSMS command (command name in text: Select Service for MO SMS Messages).
