Tethering What is it, how does it work, and what is it used for?

If you have ever run out of mobile data to access the Internet and need to receive information or send an email, tethering is the solution for this type of situation. It consists of sharing the Internet via mobile phone to other devices.

It is a widely used technology, since there are rates of the operators that have unlimited megas to navigate or with a great amount of these and that the users do not finish using them during the cycle of invoicing.

In order for you to learn more about this tool, we want to share with you the following paragraphs. You can find all the information related to the network anchor and the difference that exists with the hotspot, as well as the steps necessary to activate the tethering.

What is tethering and what is this technology for?

Tethering is the mechanism by which a mobile device can share the Internet and act as a modem or router to other phones and computers. This allows for a wired or wireless mobile network.

To perform this process is used WiFi, Bluetooth to a USB cable.

What are the benefits of using tethering to share data?

When a person shares the Internet or performs a network anchorage can generate the following benefits:

A mobile network is created

What we mean by this benefit is that the Internet can be accessed anywhere through this technology. You only need to have 4G coverage so that different mobiles that are close to the provider device can access the web without the need for cables or other types of hardware.

Share mobile data

One of the reasons why tethering is used the most is because the device that acts as a gateway has a contracted rate in which a significant amount of megabytes can be made available.

In this way, you can save money in different service providers, since you can contract a line with unlimited gigs and share it with others who have contracted a lower rate.

Internet for computers without prior installation

Tethering is also useful for desktop or laptop computers that need to access the Internet and do not have an open public WiFi network. So by using this technology the PC will be able to surf the web without having to pay anything for this action.

Download content in case of emergency

If a person needs to access their email and does not have mobile data to do so, tethering is an ideal tool. All that is needed is to give the phone that is sending the Internet signal.

There are settings to be sure

Another advantage of this technology is that you can limit the time for sharing data, as well as set passwords so that no intruder can access the WiFi network without the owner’s authorization.

On the other hand, it allows access to the web via Bluetooth, making it practical and safe. Because first you have to pair your phone and then you can share your data.

Better than ADSL

When fiber coverage is not available, this tool can be accessed as a means to replace the broadband connection.

Don’t forget that the maximum speed you can get with ADSL Internet access is up to 35 Mbps, while with 4G coverage you can reach 180 Mbps for downloading, and up to 800 Mbps for 5G.

Compatible with any operating system

You will be able to perform a network anchorage on both your Android device and iPhone, so you will not be prevented from sharing your data with people who have the phone near you.

What to consider before sharing data with tethering?

Don’t forget that when you use this technology what you are doing is sharing the mobile data you have contracted with your operator. So every mega that uses a device connected to yours spends the GB you have in your monthly plan.

By this we mean that if you do not have a rate that allows you to have a good amount of megas or are unlimited is not convenient to use the Tethering.

This is because most of the service operators have automatic renewal bonuses, so once your contracted data is finished it will renew more megas to surf without you noticing, so you will have a big surprise on your end of month bill.

Tethering vs hotspot What is better and how do these methods differ?

We already know that tethering is the technology that allows you to share the Internet with other mobiles or computers via WiFi, Bluetooth or cable. But this is not the only tool that exists to access the web by other devices, there is also the Hotspot (translated as “hot spot”).

These are access point generators that are used in public and open places (with high traffic demand) so that the web can be accessed via a wireless connection. For this it is necessary to have a router that is connected to a provider’s Internet service.

Tethering is more secure, as only authorized devices can enter the network, while in the Hotspot the network is open making it possible for any third party to see the connected devices. Don’t forget that hackers need to be on the same network to access the mobile.

Steps to enable tethering and Internet sharing from Android or iOS

The steps you will have to take to activate tethering will depend on the OS you have in your mobile. Let’s see how you have to do it in each case.

On Android

The steps you will need to follow on your Android are as follows:

  • Go to the “Settings” option.
  • Then click on “More…
  • Choose the option “Network and WiFi Zone Anchorage”.
  • Type the name of the WiFi network, set a password, when you’re done click “Save”.
  • So far you have set up tethering so that no one who is not authorized by you can enter your wireless network. What you need to do now is activate it and share the password with whomever you choose.
  • To do this you must click on “Portable WiFi Zone” (in Android versions you will find “Share Internet Access”) and activate the option.

In case you want to share it via Bluetooth, you should follow this guide:

  • What you need to do is pair both devices.
  • Then go to your mobile Internet provider and go to “Settings”, then click on “More”, choose “Share Internet Access” and finally look for the option “Share Internet via Bluetooth”.
  • On the receiving device you only have to connect via Bluetooth and accept the tethering.
  • If you want to use USB to share the Internet with a computer you must follow the same steps as Bluetooth, but choose the option “Share Internet via USB”. If you have Windows you must enable the name of the tethering by searching the option “Available networks”.

If you have a Mac computer, you’ll have to follow the same steps as Windows, but you’ll be asked if the device is trustworthy.

In iOS

With your iPhone you must follow this guide:

  • Go to “Settings”.
  • Click on “Share Internet and activate the option”.

In case you want to change the access password, you will have to click on WiFi Password and then follow the steps to complete the network name and password.

If you want to do it by Bluetooth you will do these steps:

  • Pair both devices.
  • Go to “Settings”.
  • Activate the “Internet Sharing” option.
  • Click on “To connect by Bluetooh.”

If you want to do it via USB, you’ll need to connect your phone to your Mac, update iTunes, and then choose your iPhone. In case it asks you if you can trust the computer, you must press “Trust”.

When you have a Windows connection, you’ll need to follow the same steps as with the Mac.

Alternatives to tethering What are the best connections to share the Internet?

There are other alternatives you can use to tethering, which we will show you below:

USB Anchorage

So far we’ve told you how you can connect via USB. But we don’t comment on the advantages of doing it this way.

First of all, you can share the Internet for both Mac and Windows anywhere, all you need is 4G or 5G coverage. The benefit of this is that you can be anywhere with your laptop and connect it via a cable to access web browsing.

Another advantage of this system through USB is that you can avoid the connection of open WiFi networks, which are often not secure and do not have the same speed as networks by tethering.


One of the most outstanding features of Bluetooth Internet sharing is that you can only do it with the paired devices, so security is a must. Since other mobiles that do not have your authorization will not be able to access it.

In addition, it will allow you to make a connection to a computer if you do not have a USB cable, so you will also have the same benefits of this type of connection.


This technology is related to certain rates offered by Internet operators in our country. It consists of having multiple SIM cards in different devices and being able to use all these cards as if it was in a single mobile.

This has the advantage that you will be able to use the mobile data you have contracted on each of the phones and thus save money, since you will not have to contract a line for each one.

You should be aware that phone companies provide these services in different ways, some allow you to call and browse without any limits while others only allow you to browse.

Sharing megs from the operator

This is another characteristic that some of the telephone companies in our country have. It consists of authorizing certain lines that are in the same group to use the mobile data that were contracted together.

In this way you can have a bag of megas and use them according to the needs of each mobile, regardless of the type of contract they have in each of these lines. It is also possible to transfer mobile data to a given line by means of an authorization from the holder.
