Also, bad weather can disconnect you from the internet. Your mobile will also be billed/charged if you want to use the internet on your device.

Battery problem:

All the mobile devices use a battery for charging your device. If you have no place to charge mobile battery i.e. you are away from home then it creates a problem. You cannot use your mobile device if your battery is not charged.

VPN Support:

Mobile devices also have a feature to connect to a virtual private network (VPN). By using a VPN you can hide your identity and use the internet anonymously. One benefit of a VPN is that you can also access the websites that are blocked in your country. For example, if Tiktok app is blocked in your country and you want to entertain yourself then you can connect VPN and get access to Tiktok app.


If you are connected to the internet then you are unsafe in the sense that your data can be stolen. Some apps can track your location and search terms you use on different websites. If you use your credit/debit cards online then your money is also on risk. Hackers can hack your mobile/tablet/laptop and get your confidential data from your device. So it is better to not store any of your bank details, credit/debit card details on your mobile.
