Why do I have unlimited data but its not working?
Restart the phone
Most data connectivity issues (and many other software issues on the phone) can be resolved with a simple restart. As basic as this approach may be, it actually gets the problem solved. Do not confuse turning off the phone and restarting it. Long-press the power button then hit on Restart.
Restart your device.
If restarting doesn't work, switch between Wi-Fi and mobile data: Open your Settings app and tap Network & internet or Connections. Depending on your device, these options may be different. Turn Wi-Fi off and mobile data on, and check if there's a difference.
“My mobile data is on but not working” could be caused by a minor system glitch or an error from your mobile operator that can be fixed by rebooting your phone. In that case, just reboot your phone to see if the trick works: You can restart most Android devices by long-pressing the power button for about 10 seconds.
Most probably the phone has temporarily lost it's internet connection, try updating the SIM on the network.
De-Prioritization: The Limits of Unlimited Data
It's true, with unlimited data plans, there are no limits to the amount of data you can use. There is, however, very truly limits to data speed.
What does unlimited data mean? Unlimited data means exactly that - no limitations on the amount of data you can use. So you can scroll social media, browse online and WhatsApp as much as you like. However, there is a limit on the speed at which you can use your data.
Your cellular data not working may happen for a few reasons. It may be the poor connection in your area or lack of mobile internet coverage altogether, a bug in the system, a physical problem with your device or SIM, or simple forgetfulness to turn on the cellular data or turn off the Airplane Mode.
Turn cellular data off and then back on again. Go to Settings, then tap Cellular or Mobile Data. If you're using an iPad, you might see Settings > Cellular Data. If you're traveling internationally, make sure that your device is set up for data roaming.
A slow data connection on your phone is usually caused by a poor connection in your location, network congestion, or too many background apps running. Slow iOS or Android internet is a familiar problem for smartphone owners, and there are many reasons why your phone internet is slow.
Restart your device to fix LTE mobile data issues
Press and hold the power button of your smartphone and then tap Restart. Wait a couple of seconds and turn it back on. Check your status icon and test the speed of your LTE connection by opening some websites or downloading some smaller apps.
Why is 4G not working?
Enable The Right Network Mode
If your phone is 4G/LTE, make sure you check that it's enabled in your network options. Doing this is very simple. First, go to settings and select Sim cards & mobile networks as shown in the previous steps. Go to SIM card settings and under Mobile network, tap “Preferred network type.”
LTE and 4G networks were introduced around the same time, but 4G is faster than LTE and is more suitable for IoT. Long Term Evolution (LTE) and fourth-generation (4G) networks were mainly introduced around the same time and are often marketed together.

If all your devices get no internet connection, yet your WiFi indicator is still on, the most obvious answer is that your internet provider has an outage. Before you start rebooting and shuffling wires around, it's always a good idea to check this first.
One of the most common causes of LTE problems is a glitch in the connection between your device and the network. This can often be fixed by simply turning airplane mode on and then off again. To do this, go to your device's settings and find the “airplane mode” option.
100GB data (or 100,000MB) is functionally almost unlimited. Even with video streamed in high quality you could manage around 30 hours a month (depending on the source). Chances are you don't need that much, or would be fine with medium quality, which gives you a lot more.
A 100GB data plan will allow you to browse the internet for around 1200 hours, to stream 20,000 songs or to watch 200 hours of standard-definition video. Nowadays, the key difference between mobile phone price plans is how many gigabytes of data it comes with.
For the vast majority of phone users, 50GB is more than enough. Take a look at the table below to see how much data you use, on average, for each activity on your smartphone. For reference, a MB is a 'megabyte', and approximately 1,000MB make up one GB.
For most people, 30GB of data will be more than enough to last for an entire month's allowance. When you're out and about, your phone needs to consume data to complete tasks you ask of it, such as browsing the internet or watching videos.
The standard unlimited data plan includes unlimited minutes, unlimited messages, and unlimited high-speed data up to a certain data cap. Usually this high-speed data cap is 22–23 GB.
Overall, 25GB provides a good chunk of data suitable for most people and their needs.
Why is unlimited data not actually unlimited?
Throttled Speeds
The biggest catch in most “unlimited” data plans is speed limits. It's common practice for unlimited plans to only allow access to high-speed data for a set amount, such as 25GB. After you use that much data, your speed gets throttled down.
Using too much data
Doing things on the internet uses up data. Activities such as watching movies or TV use a lot of data, and basic web pages that just have text and a few images use less. If you use more data than your plan allows, you might have to pay more, or your internet service might be slowed down.

So what's the difference between 4G and LTE, and is 4G or LTE better? In short, 4G offers a much faster speed, more stability and access to a larger variety of online activities. LTE is a half-point between 3G and 4G, so its performance suffers compared to the fourth generation.
