Call Forwarding Between SIM Cards
If one of your two SIM cards is switched off, out of coverage, or physically removed, callers trying that number just hit a busy tone or voicemail instead of reaching you on the other line. On dual-SIM Huawei phones, this happens because the two SIMs operate independently unless call forwarding between them is switched on. That's a problem if you rely on both numbers while traveling or when one card regularly drops signal.
Send a File via Bluetooth
When a Bluetooth transfer just sits there or the receiving device never shows up in the list, it usually means the two phones were never paired first. Bluetooth sharing on Huawei phones runs through the system Share menu, so picking the wrong app or an unpaired device stops the transfer before it starts. This guide walks through sending a single photo, though the same steps work for videos and other files too.
Delete a Saved APN on Huawei
If a Huawei phone suddenly loses mobile data or MMS stops working after a SIM swap or carrier update, a leftover or wrong Access Point Name (APN) entry is often behind it. Manually typed APN details or an outdated carrier profile can block a clean connection to the mobile network. Removing the faulty entry is usually what lets the phone reconnect or accept a fresh APN.
Enable or Disable Emergency Location Service (ELS)
When you dial an emergency number or send an SOS text, your Huawei phone normally shares its location automatically so responders can find you faster. If Google Location Services are turned off, Emergency Location Service (ELS) steps in to determine your position instead, and whether it is active or not can matter in a real emergency. Many people never check this toggle until they need it.
Rename SIM Card
On a dual-SIM Huawei phone, both slots often show only the carrier name, which makes it hard to tell your two lines apart at a glance. This gets annoying fast if one SIM is for work and the other for personal calls. A custom label fixes that without touching your carrier settings.
Turn Mobile Data On or Off
If apps stop loading data outside Wi-Fi range or your phone shows no internet connection away from home, mobile data is likely switched off or an app is blocking background data. Huawei phones separate the mobile data toggle from Wi-Fi, so turning it off cuts cellular internet access completely once you leave a Wi-Fi network. A missing or wrong APN can cause the same symptom even when mobile data is already turned on.
Change the AP Band for Mobile Hotspot
Your Huawei phone hands out its mobile hotspot on 2.4 GHz by default, and that works with almost any WLAN device but slows things down once several gadgets share the same channel. Laptops, tablets or streaming sticks that support 5 GHz stay stuck on the slower band until you switch it manually. This shows up as sluggish transfers or buffering whenever more than one device connects to your hotspot at the same time.
Configure Personal Hotspot Name and Password
If your personal hotspot still broadcasts the factory-set name and password, anyone nearby can recognize your phone and try to connect. A weak or default password also makes it easy for strangers to guess their way onto your data plan without asking first.
Enable or Disable Wi-Fi Direct
Trying to send a photo or stream a video straight from your Huawei phone to a TV or Fire TV Stick only works if Wi-Fi Direct is active. When the toggle stays greyed out or nearby devices simply do not show up, the feature is usually switched off or hidden inside the Wi-Fi menu. Both devices also need to sit on the same Wi-Fi network before a direct transfer can start.
Enable or Disable Data Roaming
If your Huawei phone locks onto a foreign or unfamiliar network abroad, mobile data simply stops working until roaming is switched on. Once you activate it, the phone can use a foreign carrier's mobile network, and that access almost always comes with extra charges from your provider. Leaving roaming off protects you from surprise bills but also blocks data, calls, and messages on networks outside your home carrier.
Set Location Access for Apps
If an app keeps showing local ads, weather for the wrong city, or asks for your position every time you open it, its location permission is probably set too loose. EMUI lets you fine-tune this per app instead of using one global switch. Picking the right option also affects battery drain and how much data an app collects in the background.
Enable Simple Mode
If the home screen on a Huawei phone feels cluttered with too many icons, tiny text and confusing settings menus, Simple mode can fix that. It hides rarely used functions, enlarges icons and text, and reduces the interface to the essentials many users, especially seniors, actually need. The tricky part is finding the toggle, since it sits several menus deep and is easy to overlook.
Enable or Disable WiFi and Bluetooth Location Scanning
If your Huawei phone keeps pinpointing your location even with GPS switched off, WiFi and Bluetooth scanning is likely doing the work in the background. This feature checks nearby networks and devices to sharpen location accuracy, but it can also drain battery and raise privacy concerns. Both signals can be controlled separately from the location settings.
Location Scanning via Wi-Fi and Bluetooth
Even with Wi-Fi and Bluetooth switched off, your Huawei phone can still run short scans of nearby networks and devices to pinpoint your location. This happens whenever an app with location permission asks for the most accurate fix available, no matter what your radio toggles say. The scanning behavior sits in a separate setting from the Wi-Fi and Bluetooth switches themselves, which is why turning those off doesn't stop it.
Restrict App Access to Mobile Data or Wi-Fi
If a video streaming app keeps burning through your mobile data plan even when you are not actively watching anything, background network access is usually the cause. Some apps also switch between Wi-Fi and mobile data without asking, which drains your data allowance faster than expected. You decide per app whether it may use mobile data, Wi-Fi, or both.
Turn Google Location History On or Off
Even without opening a single Google app, your Huawei phone can still log where you go through Google Location History. Many people only discover this after checking their Google account and seeing a detailed timeline of past visits. This background tracking runs independently of Maps, Search, or any other Google service, and you can switch it off directly from the phone settings.
Enable or Disable 'Ask for Location' in Browser
If websites on your Huawei phone keep asking for your location every time you open them, or never ask at all, the browser's own permission setting is behind that behavior. This option sits inside the browser's site settings and works separately from the phone's general location toggle. Turning it off stops every website from requesting your position, while turning it on lets sites ask individually.
Limit Maximum Hotspot Connections
If your Huawei phone's mobile hotspot allows up to eight devices to connect at once, uninvited users or unnoticed background traffic can quietly eat into your mobile data plan. Lowering the connection cap gives you a clearer picture of who is actually using your hotspot and how much data each session pulls.
Restrict App Downloads to WiFi Only
If apps keep downloading or updating over your mobile connection and eating into your data plan, the Play Store app download preference is likely set to allow any network. This setting exists separately from your phone's general mobile data controls, so switching off mobile data elsewhere will not stop it. Adjusting the download preference inside the Play Store settings gives you direct control over when new apps and updates are pulled onto your Huawei phone.
Set Default SIM for Mobile Data
On a Dual SIM Huawei phone, mobile data can silently switch to the wrong SIM card, leading to unexpected charges or slower speeds. This happens when EMUI has never been told which SIM should handle mobile data by default. Without a fixed assignment, the phone may keep using whichever SIM was configured last.
Connect to a Wi-Fi Network
If your Huawei phone shows no internet access or keeps dropping the connection, the Wi-Fi function itself might still be turned off. You need an active Wi-Fi connection before you can join a private network with a password or a public hotspot. Once Wi-Fi is switched on, your device lists every network within range so you can pick the right one.
Connect to Wi-Fi via WPS
Typing a long Wi-Fi password on a Huawei phone is easy to get wrong, especially with mixed-case or special characters. If your router has a WPS button, you can skip password entry entirely and pair the devices directly. This only works if WPS is enabled on the router and the phone is close enough to receive the signal.
Unpair a Bluetooth Device
Old Bluetooth connections pile up fast on a Huawei phone, especially after pairing with rental cars, speakers, or a friend's headphones you only used once. If a device you no longer use still shows up in your paired list, a broken or outdated pairing can also cause connection errors with a replacement device sharing the same name. Removing the pairing clears the stored connection completely, so the phone treats it as brand new next time.
Enable or Disable Wi-Fi+
If your Huawei phone keeps jumping onto mobile data even though you are sitting right next to your router, Wi-Fi+ is probably the reason. The feature watches your current Wi-Fi signal and switches connections on its own once it judges the network too weak. That can mean surprise mobile data usage or a phone that never stays on the Wi-Fi network you actually want.
