However, not everyone has the opportunity to connect such a device exactly when it is absolutely necessary. they forgot to take it with them, ran out of money, forgot, did not buy, or corny your gadget does not have a USB connector. Today I will show a way to access the network from any device and from anywhere. We will use the phone as a modem for a laptop and any other gadget. Yes, yes, the most ordinary phone or smartphone with a working SIM card, which will become for us a wired modem or wifi router.

To use the phone as a modem, you will need to make some settings on the computer, which can be a little difficult for a beginner. Therefore, the easiest way to use it is as a router distributing wifi. over, in this mode, it can work both on the Android that is widespread today, and on iOS. By the way, the iPhone already has a built-in function to connect the phone as a modem and distribute Internet from it. We are talking about devices (it can be not just a phone, but a smartphone or even a tablet) with support for SIM cards, and therefore GPRS / 3G / 4G communication.

But it also happens that on a laptop, and especially on a stationary PC, there is no built-in or external wifi adapter. It is in this case that the function of connecting the phone as a modem via a USB cable will come to the rescue.

In this case, the Internet will be distributed the one that receives this phone through a SIM card from a mobile operator.
