It seems that Huawei phones don’t seem to have that feature, which may be due to certain manufacturer's reasons. Its skinned UI (EMUI) provides the feature in a slightly different place.
If you go to your data management screen, you will find that it does
not offer that feature at all. Instead, it shows you your daily usage,
and that is about it.
This similar feature is found in data traffic management.
Depending on your EMUI version, follow this proceedure:
Go to Settings (All) → Data traffic management → Package settings (or gear icon in later EMUI versions). You should get a screen looking like this:
Here you actually get the Android Data Traffic manager, but a super version of it. You can set daily limits, start the day of the month
for your package, disable data if you go over limit to save you money,
and set various limits and reminders
Since the feature is somewhat hidden, another probable workaround is installing a 3rd party open source tool Activity Launcher(No root required).
- Under activities select all activities.
- Select Settings
- Search for data usage
Here you will find the options you need to change the mobile data cycle date similar to what you do in stock versions.
Another workaround is installing an altogether data manager application, that takes over the default monitoring of data, cycles etc.
From experience of many users you can search the appropriate one from Playstore e.g ( My Data manager, 3G watchdog etc) which are also very flexible when it comes to changing data cycles, limits, reminders and so forth.
