What is the use of the Hejiaqin app? I had long since renamed it China Mobile Aijia, switching the optical modem to WiFi and TapBand, so you can do it even when you're not at home

helped my childhood friend figure out the super admin password for the mobile optical modem that night (I write about the process in the super-secret article), he casually asked: The 'He Jiaqin' that the technician asked him to install during the setup—he couldn't find it in the app store no matter how hard I searched. Was it taken down? I picked up his phone and laughed at it—it wasn't taken down, but the name was changed. This app is now called Mobile Love Home , and this was in October 2024. Just this one name change—I guess half of the people are like childhood friends, thinking they've remembered the wrong name.

first recognize the door: Hejiaqin has changed its name to China Mobile Aijia

Let's

sort out the timeline. Hejiaqin is the smart home app of China Mobile, used for managing optical modems and mobile delivery smart devices. In October 2024, China Mobile upgraded and renamed it Mobile Aijia , with a straightforward positioning: the unified entry point for smart homes. If you search for 'Hejiaqin' in an app store now, the official store will usually redirect you to 'Mobile Love Home.' If the icon is changed, the developer is still China Mobile (Hangzhou) Information Technology Co., Ltd.—recognize the developer's name, but don't download third-party customization packages.

also clarify a more common confusion: many people have the "China Mobile" app installed on their phones and think they can manage optical modems there. No, it is not allowed. The China Mobile app manages your number and plan , and you can check your phone bill and handle business with it. The Aijia management system is your device , such as the optical modem, FTTR, and the camera provided by China Mobile. The two apps did use the same phone number for login, but their functions didn't match—like a business hall and a maintenance technician each doing their own thing.

binding is the first hurdle; if you can't bind, check these three first

install the app and log in with the broadband-bound phone number. Next, bind the optical modem. Many people get stuck at this step. First, lay out three prerequisites—none of them can be tied to it

even if all three are present, they still can't tie it together—basically, three sources come from. The first most common is device that has previously linked another account . Used optical modems and worker machines that technicians casually tied under their own user accounts during assembly all fall into this category. You have to unbind your original account first before binding you. Don't skip the second simple trick: restart the optical modem and router, wait until the lights stabilize, connect your phone to WiFi and browse for a few minutes, then go back to the app and tap 'Add'—that's how Huawei's official troubleshooting recommendations work, and my childhood friend's device worked the second time. The third issue is on the account side. If you can't handle it yourself, call 10086 and have the RMS platform side in the background unbind the optical modem and account again. This step can be handled remotely by customer service.

the five most valuable things in daily life

After binding

, the app homepage opens to the gateway device, and it can do more than most people imagine. I went through each of them one by one and picked the five most valuable ones, saying:

check the device list. who is connected to your network, what your name is, whether you're online or not—it's clear at a glance. You can also view the router backend from my childhood friend, but only here can you see all the devices under the optical modem's name (like the phone my technician connected during speed tests).

Change the WiFi name and password. the modem's built-in WiFi signal, you can change the name and password directly in the app, no need to remember 192.168.1.1 or access the backend. After a wave of guests at home, they wanted to change their passwords and just pressed a couple of times while lying down. If you don't like the internet-friendly device, you can directly block and kick them offline. It's the same approach as I wrote before Tianyi Gateway web version kicking people out, but it's just moving the battlefield from computer to mobile.

speed limit. the TV box secretly caches at midnight, the child's tablet opens the live streaming family card, and by adjusting the upload and download speed in the device details, the effect is immediate.

speed measurement. App built-in WiFi speed test runs through your own mobile node. Before reporting for repair, you should test it first so you have a clear idea when communicating with the technician.

green internet access. means parental control and setting internet time slots for designated devices. I wrote about this feature in the about the optical modem restricting children's internet access—China Telecom does it in the Xiaoyi Butler app, China Mobile in Aijia, and the logic is pretty similar: rules run in the cloud, optical modem executes it, and it manages the whole device.

real trump card is that even outsiders can control

these things can be done by the backend of the Guangmodem platform, so why should an app be a must-have? Just one thing: it travels in the clouds, no need to be home .

The

link is as follows: your mobile app → Mobile's cloud → RMS platform → your optical modem. The phone and optical modem don't need to be on the same WiFi; commands bypass from the cloud. The webpage backend ( the process of logging into the optical modem backend ) requires someone at home and connected to the optical modem's network to get in; once outside, it's a disaster. A childhood friend remembered the WiFi password at home on a business trip that seemed to have been revealed in a relatives' group, so they took out their phone at a highway service area and changed the password—that's the point of the app.

remote restart of the optical modem feature. Some models have it on the app's gateway detail page, others do not. Check the firmware. For models without it, remote restart is impossible, which is normal: restarting the optical modem means disconnecting both landline and IPTV, while Mobile is cautious about this button.

want to keep the app line, don't delete the entire RMS channel

there's an unavoidable trade-off here, so you have to read it together with the ultra-dense one. The configuration of the mobile optical modem is quietly pushed back by RMS in the middle of the night, which is a headache for many. The solution is to access the super admin backend to handle the remote management channel. But be mindful: turning off "periodic reporting" and deleting the entire RMS WAN connection are two different . The former cuts off the habit of regularly overwriting your configuration, while the latter uproots this cloud cable.

The price of deleting

entire app is the app going blind—the link from the phone to cloud to the optical modem is cut off, and you keep spinning the device list in the app, and no response when changing the password. It's the same logic as how Xiaoyi Manager malfunctions after the telecom deleted TR-069 (I noted this trade-off in the of Xiaoyi Butler in ). My childhood friend's last choice was to just turn off periodic reporting and keep the channel open: the specs wouldn't be so late at night as a dance, and the app would still be alive. If you don't plan to use the app for remote management, deleting it is a simple option—everyone gets what they need.

these few things can't be handled by the app, you have to go back to the web backend

be blunt: apps are not a master key. It can't touch the deep-water areas: modifying bridging, dynamic WAN connections, port mapping, etc., and you still need a super admin account to go into the 192.168.1.1 webpage backend. The operation method is in the from Mobile Chaomi. In the app, connect the optical modem WiFi switch node to search. Some models don't have some options, and if not, return to the backend—if you want to completely shut it off because the fiber modem WiFi is fighting with your router, you can check my previous article about turning off the optical modem WiFi. IPTV and landlines are even less of its jurisdiction; that's a matter for another channel.

here's another fun fact: I've never used the same app on Unicom's side. China Telecom has Xiaoyi Butler, China Mobile has Aijia—their approaches are almost exactly copying each other. If you have dual broadband households, the two apps each manage their own cats and deny each other's responsibilities.

order: first, search for 'Mobile Love Home' in the app store and install the right app. Broadband phone number login, and at home, connect to the fiber modem's WiFi to complete the binding; If it can't be bound, follow the three layers of unbinding, restarting, and rebinding, or rebinding in the 10086 backend; Once the binding is successful, the five daily tasks can basically be done to say goodbye to the computer. If one day you follow the approach from Chaomi and start the remote management channel, think carefully before you decide whether you still want the app line. The solution is to only turn off periodic reporting.
