Turn On Automatic Network Selection
If your Realme phone stopped switching networks automatically after a trip abroad or near a border region, chances are automatic network selection got switched off along the way. The phone then stays locked to whichever carrier it last connected to, even when a stronger signal from your home provider is available. This usually happens after a manual carrier search or a change made in roaming settings.
Wi-Fi and Bluetooth Scanning for Location Accuracy
If your Realme phone still detects nearby Wi-Fi networks or Bluetooth devices after you switch both radios off, Wi-Fi and Bluetooth scanning is running in the background. This system function lets apps and location services use nearby networks and devices to sharpen your position, independent of the actual Wi-Fi or Bluetooth toggle. That extra accuracy comes with a trade-off in battery use and background access for apps you may not want scanning at all.
Set a Data Limit for the Personal Hotspot
If mobile data runs out fast whenever devices share your Realme hotspot, no restriction is currently in place. Realme UI lets you cap the exact amount of data the personal hotspot can pass through before it shuts off on its own. Without that limit, laptops or tablets connected to your phone can quietly burn through your plan.
Set Default SIM Card for Calls
Every outgoing call on a dual-SIM Realme phone triggers a prompt asking which SIM to use, and that gets tiring fast. This happens because the calling preference is still set to 'Always ask' instead of a fixed line. Locking in one default SIM removes that extra tap before every call.
Turn Location On or Off
If weather widgets, maps or navigation apps suddenly stop finding your position on your Realme phone, the Location service is often switched off without you realizing it. A GPS signal that keeps searching in the background can also drain the battery faster than normal. Whether Location is on or off decides which apps can even request your current position.
Change SIM Card Name
When two SIM cards on a Realme phone belong to the same carrier, both slots show the same label in call logs and data settings. That makes it hard to tell at a glance which SIM you are actually using for calls or mobile data.
Auto-Connect to the Best Wi-Fi Network
If your Realme phone clings to a weak or slow Wi-Fi network even though a stronger one is available nearby, the Wi-Fi Assistant feature is likely switched off. This tool compares stored networks in range and automatically picks the strongest signal, but only when enabled. Without it, you have to switch networks manually every time you move between rooms or floors.
Unpair a Bluetooth Device
If a Bluetooth accessory like a headset, tablet or another phone still shows up as paired even though you no longer use it, the connection stays active in the background on your Realme phone. Old pairings can block new connections or keep permissions alive that you actually want to revoke. Removing the pairing clears these saved settings completely.
Set a Monthly Mobile Data Limit
If your mobile data plan runs dry days before the billing cycle ends, you probably have no monthly limit configured on your Realme phone. Realme UI tracks consumption on its own, and that count can drift from what your carrier actually bills. Without a limit set, you only find out about overuse once your provider throttles speeds or adds extra charges.
SIM Card & Dual-SIM Settings
On Realme phones with two SIM slots, you decide which card handles calls, texts and mobile data at any given moment. This area covers how that assignment works, how to switch between active SIMs, and why one SIM might stay idle while the other carries all your data traffic. Understanding these settings helps you avoid dropped calls, unexpected roaming charges, or a SIM that silently stops working.
Limit Personal Hotspot Connections
When several devices join your Realme personal hotspot at the same time, mobile data disappears fast and the connection gets noticeably slower for everyone. Realme UI lets you cap the number of devices allowed to connect, so guests or family devices cannot eat into your data plan unnoticed. Without a limit, any nearby device with the password can join until you run out of data.
Turn Wi-Fi On or Off
If your Realme phone will not join a nearby Wi-Fi network, the Wi-Fi radio itself might be switched off rather than the connection settings being wrong. You can flip Wi-Fi on or off either from the quick settings panel in the status bar or from the dedicated Wi-Fi menu. Leaving Wi-Fi enabled without an active connection also drains the battery faster than it should.
Add Access Point Names (APNs) Manually
If mobile data stops working or MMS messages won't send on your Realme phone, the access point name from your carrier is often missing or incorrect. Realme UI normally pulls these APN settings automatically from your SIM, but a carrier switch, a factory reset, or a corrupted profile can leave the field empty. Without a valid APN entry, your phone cannot establish a data connection at all.
Turn On/Off Emergency Location Service
Realme phones can send your exact location the moment you dial an emergency number, even if you never touched a location setting yourself. Emergency Location Service (ELS) runs independently from Google location controls, so switching those off does not stop it. If you want to decide for yourself whether your position goes out during an emergency call, ELS itself needs to be adjusted.
Connect to Wi-Fi via WPS
Typing a long Wi-Fi password on a small keyboard gets annoying fast, especially with mixed-case characters and symbols. If your router has a physical WPS button within reach, Realme phones can skip the password screen entirely and pair directly with Wi-Fi Protected Setup. No password entry, no QR code needed.
Allow or Block Apps From Scanning for Wi-Fi Networks
If your realme phone still detects nearby Wi-Fi networks with Wi-Fi switched off, a background feature called Scanning always available is likely active. Location services and certain apps use this scan data to improve accuracy, even without an active connection. Turning it off stops that background search, but some location-based apps may become less precise.
Auto-Disable Personal Hotspot When Idle
Leaving the personal hotspot active on your realme phone even when no other device is connected drains the battery and keeps the connection open longer than necessary. Realme UI can switch off the hotspot on its own once it has been idle for a while, but the option is easy to overlook in the settings. Without it enabled, the hotspot only stops when you turn it off yourself or when every connected device disconnects.
Mobile Data Warning and Limit
Mobile data warning and limit settings let your Realme phone track how much cellular data you use each billing cycle and alert you before you run out. You set a threshold, and the phone warns you as you approach it or cuts off data entirely once you hit your limit. This is especially useful if your plan has a hard data cap or you want to avoid unexpected charges from your carrier.
Manual Network Selection
If your Realme phone keeps latching onto a weak home carrier near a border or in a rural spot, calls drop and data stalls even though a stronger foreign network sits right next door. Automatic network selection picks whatever signal is strongest, but that can also mean an expensive roaming partner or a 2G-only connection. Switching to manual selection lets you pick the exact network yourself instead of leaving it to the phone.
Auto Switch to Mobile Data
If your realme phone stays connected to a weak Wi-Fi network instead of switching to mobile data, streaming stalls and calls drop even though you have full signal on your carrier network. This happens because Wi-Fi Assistant, the feature that hands off to mobile data automatically, is turned off by default. Once it is active, your phone checks the actual Wi-Fi signal quality and switches over on its own when needed.
Rename a Paired Bluetooth Device
If your Realme phone only shows a serial number, MAC address, or model code for a paired Bluetooth device, keeping several connections apart gets confusing fast. This happens when the accessory does not send a readable name during pairing. Renaming the entry fixes the display without breaking the existing connection.
Set Start Date for Data Usage Stats
If your mobile data limit resets on the first of the month but your provider bills on a different day, your usage stats never match your actual bill. Realme UI lets you pick any day of the month as the reset point for the data usage counter, but the option is buried a few taps deep in the mobile data settings. Without adjusting it, your data warning and limit alerts stay out of sync with your real billing cycle.
Block Mobile Data or Wi-Fi for a Single App
If YouTube, Netflix or a background app keeps eating through your mobile data plan even when you only meant to use it on Wi-Fi, the app's individual network permission is likely still set to allow both connection types. The same issue shows up in reverse when an app refuses to load unless mobile data is switched on, even though you are connected to Wi-Fi. Realme UI lets you control each app's network access separately from the general Wi-Fi and mobile data toggles.
Turn On/Off Personal Hotspot
If your laptop or tablet won't pick up your Realme's internet connection, the personal hotspot toggle is often switched off or buried in a settings menu you don't check often. Some phones also auto-disable the hotspot after a period of inactivity to save battery, which can look like a connection failure on the other device. Knowing exactly where this switch lives and what limits it saves a lot of guesswork.
