If you are go out somewhere and find that there is no Wi-Fi connection for your laptop or you do not want to risk using a public Wi-Fi network, you can always turn on your phone as a Wi-Fi hotspot. Using your phone this way is often called tethering and is usually quick and easy to set up, but there are a few things to keep in mind.

What you need to know about tethering
Different operators and plans have different rules for tethering. To avoid unexpected charges, always check before using your phone as a hotspot. Tettering is usually included, but will be reported in the amount of your data.
Even with supposedly “unlimited” data plans, there are some limitations. Surfing the web shouldn’t be a problem, but if you want to stream video to your laptop using your phone as a Wi-Fi hotspot, for example, you may encounter limitations. Adjustment is common when certain data limits are reached, so check the fine print of your plan.
For tethering to work well, you will need a strong mobile data connection on your phone. When your phone acts as a hotspot, it works just like a mini router and appears as a simple Wi-Fi network option, so it’s vital to set a password or anyone can connect and use your data.
Although it is usually slower than regular Wi-Fi, a strong 4G or 5G signal will allow relatively fast speeds. Using your phone as a hotspot will also drain the battery quickly, so it’s a good idea to take a portable charger and keep in mind that this can cause your phone to become very hot.
