Gone are the days when carrier pigeons were our source of communication. We have evolved drastically, and now we have the gift of technology. Technology advances, and so do our interests. More than 70% of the world’s population has a mobile device, with the smartphone being the most common type of device. Smartphones are therefore also responsible for the most significant cause of web traffic worldwide.

We have become so habitual of having an internet connection 24 hours a day, right in the palm of our hand. The moment the Internet fails to connect is the moment we need it the most. In order to cater to our needs, it is essential to be up to date about new products in the technological world, possibly making our lives easier.

Portable Wi-Fi, also known as pocket Wi-Fi, is that palm-sized gadget that can get you online, anywhere in the world.

How Does a Portable WiFi Router Work?

The portable Wi-Fi router is just like your internet box at home, but instead of being attached to a phone cable, it has a SIM card inserted inside. Its basic function is to broadcast the Internet to the compatible devices around it, like Smartphones, tablets, cameras, or personal computers. A portable Wi-Fi device will enable you to set up your private internet connection, practically anywhere in the world, on more than ten devices simultaneously, including phones, laptops, tablets and iPads, games consoles and cameras, etc.

Portable devices are available in many types. Usually, they can tether to the LAN connection of the Internet network. Some Wi-Fi routers may also tether to the 3G or 4G data connection of your telecom provider.

A portable Wi-Fi router may connect to the Internet in multiple ways. Some of the major ways to use a portable Wi-Fi router are given below:

  • Using an ethernet connection: This method is useful when you have multiple devices which have to be connected to the Internet.
  • Using a cellular network: This is possible when your router has a sim card inserted.
  • Using public Wi-Fi: This is suggested if your router can create a secure connection.

A cellular network-based Wi-Fi router is most commonly used. In simple words, the portable Wi-Fi router acts as a mobile Wi-Fi hotspot. This mobile router converts 3G or 4G connection into a private Wi-Fi signal for your different devices.

Therefore, it works as a Wi-Fi access point at home, generating a Wi-Fi radio field of about 10-15 meters. It does not require you to install cables and software to use it. You turn it on and follow the directions.

Initially, setting up a portable Wi-Fi router is simply the case of inserting a SIM card and turning it on. Within no time, you can be surfing the Internet on several devices simultaneously. If you get an ‘unlocked’ portable Wi-Fi device, this means you can use any SIM card, from anywhere in the world, inside it.

Therefore, the benefit of this is that you can get the lowest rates, and you can use a worldwide functioning data SIM or a local SIM in it. The portable Wi-Fi device works anywhere, but the SIM card needs to be programmed to operate in different zones.

Portable Wi-Fi is one of the devices used regularly in many households and offices. You can choose the data package and pay for the rental duration. The internet provider activates post-rental payment of the device, and then the device is ready for use. It is assigned a username and password, which are required to access the service.

You can also reset the username and password if you need. All the trusted systems can access the Internet through this portable Wi-Fi. Portable Wi-Fi being wireless makes connectivity a lot easier and moveable while traveling. A Portable Wi-Fi router also brings in the convenience of international travel with undisrupted connectivity. It is ideal for people who travel for work and need a secure and reliable connection.

Today we are surrounded by multiple public networks. Relying on them can be risky and can be fatal for the devices. It is not simple to identify a secure network. Your portable Wi-Fi network will provide stricter encryption rules. You can trust it with your data and rely on it to access sites even for confidential data transfers or banking transactions. With your device, you can use the latest safety standards and establish any password rules you want.


The need for the Internet has become as vital as electricity. Whether for work or pleasure, the ability to access the Internet regardless of your location is a necessity. With portable Wi-Fi everywhere, you can ensure access to secure and high-speed Internet at affordable prices, even on the go. A portable Wi-Fi is a perfect item for those who need a safe, permanent, and mobile internet connection.
