Some of the things mentioned here are something most of the regular users did not know and found them incredibly useful. This may even save you financially and give you a heads up as a new smartphone user.

Network Connectivity

Mobile devices connect to the open Internet via the variants of 802.11 Wi-Fi standards. There are a bunch of Wi-Fi standards out there. This is a quite common use case of smartphones. You tap on the Wi-Fi connection found inside the quick setting tray. If the network is properly configured with encryption methods like WPA, WPA2, and WPA3, you need to type in the login information like name and passwords to get access to the network. You will have a list of Wi-Fi available to you upon turning on the Wi-Fi. From there, tap on to the network which is yours or you want to have access to and type in the proper credentials.

Once you are on the network, every mobile device stores that network access information. This is typical behaviour of any device that connects to a Wi-Fi network. By any chance, if anybody changes the name of the Wi-Fi or password, you will be failed to connect to the Wi-Fi. You will have to delete the profile of the previously saved network and re-type the network name and password or in most cases, just tap into the new network name and enter the password. Forget this network is how the previous profile is deleted. By any chance, if you need to cut off all connections to the Wi-Fi or signals in general, you can simply turn on the airplane mode, this will cut you off from any incoming and outgoing signals. For instance, before getting on board a flight.


Almost every device let you get on to the cellular data services to get you access to the Internet. This is undoubtedly one of the convenient features of having a smartphone. You can get access to the Internet from anywhere and surf the Web.

One of the things you might want to keep in mind is that, by default, your phone uses cellular networks for Internet connectivity by using data roaming. What this does is, as you travel around, your phone’s signal jumps from one coverage area to another to provide you with the signal. This could be your carrier or others. This is great and inexpensive as long as you are inside the country. If you are out of the country and your data roaming is on, you can find yourself in for a shock. You can find yourself with a pile of bills as soon as you come back to the country. To avoid this, you might want to get a roaming plan from your carrier, which is still expensive but not as high as you would find yourself billed with an accidental roaming charge.

If you do not need to connect to the Internet when you are out of the country, simply turn off the roaming data. You should find these settings inside the settings app. Most of the settings apps now come in with a search bar, type in ‘data roaming’ or ‘roaming’, whatever settings you are looking for, try using the search bar for faster search. One other thing is, that you can completely turn off the cellular plan completely or shut off selective cellular services if your device offers you so. You would want to turn off the cellular data completely if you do not have an unlimited data plan and getting close to the limit. Not only this but, there is some security issue involved for which you want to disable the data plan.
