Have you just bought a Huawei or HONOR smartwatch or smartband and don't know how to connect it to your Android smartphone? Have you installed the Huawei Health companion app but are unable to continue with the pairing procedure? 
In this guide, we explain the steps necessary to download and install HMS 4.0 (Huawei Mobile Services) to be able to make the most of your new smartwatch or your new Huawei or HONOR smartband. So let's see how to solve connection problems with devices such as Huawei Watch GT 2, Huawei Watch GT 2e, Huawei Watch GT, HONOR MagicWatch 2, HONOR MagicWatch, Huawei Band 4 Pro, HONOR Band 5, Huawei Band 4, Huawei Band 3 Pro, HONOR Band 4 and others.
Huawei Health and HMS 4.0
You have just purchased a Huawei or HONOR smartwatch or smartband and following the instructions in the package, and also visible on the smartwatch, you have installed the Huawei Health app on your smartphone.
Now, rightly, you think that it is enough to start the new application and follow some simple instructions to complete the operation. If your smartphone is a HONOR or Huawei then you are right and you just need to follow a couple of simple instructions on the screen to complete the configuration and start enjoying your new smartwatch or smartband.
But if the smartphone is from another manufacturer and you have never paired Huawei wearables, it is likely that the writing you see in the screen below will appear:
If you do not have a Huawei or HONOR smartphone it is highly unlikely that you have already installed AppGallery, so the first thing you will try to do is try to download Huawei Mobile Services from the Play Store, at least for the most savvy users. It is likely that the less experienced are already lost, given that there is no link that allows, at least, to automatically open an application store.
The Play Store is not a viable path, since you will only find the 3.0 version of Huawei Mobile Services, absolutely useless for this case. It is therefore necessary to perform some manual operations to solve the problem. Remember that at the end of the installation you will not find any icon for the Huawei Mobile Services, which can still be managed or uninstalled through the application management in the Settings of your smartphone
How to download and install HMS 4.0 (download)
There are two ways that allow you to download and install the coveted Huawei Mobile Services in version 4.0 on Android, whether they are Samsung, LG, Google, Sony, HTC, OnePlus, Motorola, Nokia, Realme, Oppo, Xiaomi, Redmi, ASUS or from yet another brand: manually download the installation file from secure sources, such as APKMirror, or install AppGallery, which allows you to simplify any future updates. So let's see the steps to follow for both solutions, with very simple operations that will require a few clicks to be completed.
Installation with AppGallery: download APK
If you want to simplify the installation process and make sure you always have the latest version of Huawei applications, the best solution is to install AppGallery. Just follow the instructions on the official Huawei page which provides you with a link to download the alternative store.
Once AppGallery is installed (you may be asked for permission to install applications from unknown sources) simply search for HMS to get the latest version of Google services. Usually on the AppGallery there are more recent versions of the apps, both HMS and Huawei Health, so this solution is the most suitable for those who want to be sure they always have the most recent version and compatible with the greatest number of products. Once the installation is complete, you can continue configuring the new smartband or smartwatch without further problems.
Manual installation: download APK
It is definitely the simplest operation to perform, since you just need to download this APK file in the internal memory of your smartphone and proceed with the installation. Android may ask you to provide permission to install applications from unknown sources, if you have not already granted this permission. Once the HMS 4.0 are installed, you can return to Huawei Health and continue with the pairing of the smartwatch or smartband, without any other hitch.
Conclusions
As you can see, the procedure is not particularly complex, just a pity that Huawei does not mention it in the installation procedure and abandons its users in such a delicate phase of configuration. A direct link to the apk file to install would have been enough, or a link to a page that explains in a simple way the procedure to follow, so as to make the operation easy even for beginners. This is what you need to download and install the HMS (Huawei Mobile Services) in version 4.0, useful for using your smartwatch or your Huawei or HONOR smartband.
