You can do a lot of cool things with your phone! Phones have this fantastic ability to connect to the internet as long as you are within range of a wireless network provider.
Did you know that your carrier data can be shared with any other device? With a few simple steps, you can turn your phone into a mobile hotspot and tether data to a friend nearby.
So, you may be wondering, "How does tethering work?"
What exactly is Data Tethering?
Data tethering is the process of converting your mobile phone into a modem. Effectively, you can turn on your mobile hotspot from your phone's settings app, under cellular, which creates a mobile network (seen under Wi-Fi connections).
Your phone will generate a password that you can share, and anyone with your password will be able to connect to your portable Wi-Fi hotspot via data usage.
There are several types of tethering, which are as follows:
- Tethering over Wi-Fi
As previously stated, Wi-Fi tethering is one of the most common types of tethering. You effectively create a Wi-Fi hotspot with your wireless data and then allow another device to connect to the temporary Wi-Fi network you've created.
This means that a laptop, tablet, or computer within range of your phone is connected to the internet. While Wi-Fi tethering is generally quite fast, it depletes your battery quickly.
- Tethering via Bluetooth
Bluetooth tethering can be enabled on an Android phone when it is connected to another Android device. It's essentially the same process as setting up a Wi-Fi mobile hotspot, but the binding connection is now made using Bluetooth technology.
Keep in mind that this will still consume data and that the connection speed will be slower than on the primary device. While Bluetooth tethering is slower than other types of tethering, it is more battery efficient.
- Tethering via USB
When you use a USB cable to connect a phone to another phone, tablet, or laptop, you are tethering. USB tethering works best with another phone.
The USB connection provides the strongest and most direct internet connection, but it can be taxing on your device.
What exactly is a phone hotspot?
The act of sharing data between devices is referred to as data tethering, and the device that is sharing data is referred to as a portable hotspot. (A hotspot-capable device also supports tethering.)
The only requirement for setting up a personal hotspot is that the device has mobile data.
For data connectivity, most Android phones, Apple phones, and some tablets will have an IMEI number built in. You can quickly learn what types of SIM cards your phone can use by checking your IMEI settings on your device or dialling *# 06 #.
You can use your IMEI to see if your device supports dual-SIM connectivity and digital eSIM cards.
What exactly is an eSIM?
An "embedded" SIM card is referred to as a "digital eSIM." If your device supports eSIM, you can download data packs from the Airhub store to use as a portable hotspot.
Simply ensure that you have an internet connection, and you will be able to download a corresponding plan to your phone.
Pre-programmed data
Keep in mind that because the Airhub data packs are pre-loaded, you can only tether as much data as you purchased.
If you have a data plan with your primary carrier, you may be charged an "other data" fee for using the hotspot. Check with your service provider to see if tethering is charged extra, even if you have unlimited data.
SIM and eSIM Setup for a Phone Hotspot
Setting up a personal hotspot is simple, whether you use a USB cable, a Wi-Fi hotspot, or Bluetooth.
In terms of Wi-Fi
Go to settings > "cellular" > "find your cellular line" > "setup personal hotspot"
In terms of Bluetooth (Android), Navigate to Settings > Locate "Bluetooth" > from your Bluetooth, then "pair new device" or "connect existing device." Connect the secondary device to the primary device.
For USB (Android) Connect your phone to the device you want to connect via USB. Go to Settings > Look for "portable hotspot" or "personal hotspot" > Find the "USB tethering" menu and enable it.
Things to think about when tethering
Keep in mind that your mobile data service will differ from carrier to carrier, which means there may be hidden costs or a tethering fee, depending on your agreement with your provider. If you are unsure about your data limits for tethering other devices, always consult your provider.
Tethering is available on the majority of phones and devices.
Here are a few things to keep in mind while tethering:
Your strategy will be heavily reliant on far more data than you realize: Unless you have an unlimited data plan, be aware that your tethered connection will provide high-speed data to another device or devices. Be cautious about which devices you give your hotspot password to, as any data they use will be deducted from your plan. It is recommended that you only turn on your hotspot when the other person requires data.
There is a limited range: mobile devices can only connect to your phone's hotspot if they are close to you. The range varies depending on the phone and network type, but in general, any device within 10 feet of the phone will be connected. This is why it is best to only allow access to your hotspot for a limited time.
Tethering can be draining on battery life. The battery life of your phone is entirely dependent on what you enable on it. Bluetooth, apps, web/data services, and tethering all contribute to your mobile usage. The good news is that all of these hardware factors can be limited by modifying the software. Make sure to go to your settings and disable any apps or web services that are taxing your device when not in use.
Tethering a mobile hotspot with an Airhub eSIM
These rules generally apply to most plans, but if you're using the Airhub app and want to tether data from your eSIM data plan, there are a few other things to consider:
Global carrier service will vary by region. Keep in mind that if you use the Airhub "Global eSIM," your wireless connection speed will vary across our 90+ global providers. The Wi-Fi network and subsequent Wi-Fi connection will differ depending on where you are in the world. Depending on the network name, this could be 3G, 4G, or LTE. You can always check the "additional information" tab within "my eSIMs" to see which network your Global SIM will be part of.
Tethering speeds will differ by region. Even within a single country, carrier speeds are determined by the existing infrastructure. If you live in a region with slower network speeds, keep in mind that your tethering speed will be limited to a fraction of your data speed.
You now understand how to make the most of your Wi-Fi hotspot while tethering.
