Have you ever noticed the "E" symbol on your iPhone's status bar? It's not the same as the "LTE" or "5G" symbol, but it's not the old-school "3G" either. So what does it actually mean? In this article, we will discuss the purpose of the "E" symbol on your iPhone and what it signifies.
What is the "E" Symbol on iPhone?
The "E" symbol on your iPhone means "Edge" network, which is a cellular data network technology that was used before the introduction of 3G and 4G LTE networks. Edge is a slower data network than 3G or LTE, but it is still faster than the original 2G network. The Edge network provides a maximum data transfer speed of up to 384 kbps, which is about 10 times slower than 3G and 4G LTE networks. However, the Edge network is still useful in areas where 3G or 4G LTE networks are not available.
How Does the Edge Network Work?
The Edge network works by using the same radio frequencies as the original 2G network. The difference between the Edge network and the 2G network is that the Edge network uses a more advanced modulation scheme, which allows it to transmit data at a faster rate. The Edge network also uses a packet-switching technology, which means that data is broken up into small packets and sent over the network in a more efficient manner.
When Will You See the "E" Symbol on Your iPhone?
You will see the "E" symbol on your iPhone when you are in an area that does not have 3G or 4G LTE coverage. This could be in a rural area or in a building with poor reception. The "E" symbol will also appear if you have turned off cellular data on your iPhone or if you are using a prepaid SIM card that does not support 3G or 4G LTE networks.
How to Turn Off Cellular Data on iPhone?
If you want to turn off cellular data on your iPhone, you can do so by going to the Settings app and selecting Cellular. In the Cellular settings, you can turn off the Cellular Data option, which will disable cellular data on your iPhone. You can still use Wi-Fi to connect to the internet if it's available.
Is the Edge Network Still Relevant Today?
The Edge network is still relevant in some parts of the world where 3G or 4G LTE networks are not available. Some older iPhones and other mobile devices still use the Edge network as their primary data network. However, as more and more areas are getting 4G LTE coverage, the Edge network is becoming less relevant. In fact, some mobile carriers are starting to phase out their Edge networks in favor of 3G and 4G LTE networks.
How to Check Your iPhone's Network Coverage?
If you want to check your iPhone's network coverage, you can do so by going to the Settings app and selecting Cellular. In the Cellular settings, you can see the network coverage of your iPhone. If you see the "E" symbol, it means that you are in an area with Edge network coverage. If you see the "LTE" or "5G" symbol, it means that you are in an area with 4G LTE or 5G network coverage, respectively.
In conclusion, the "E" symbol on your iPhone signifies that you are connected to the Edge network, which is a slower data network than 3G and 4G LTE networks. The Edge network is still relevant in some parts of the world where 3G or 4G LTE networks are not available. However, as more and more areas are getting 4G LTE coverage, the Edge network is becoming less relevant. If you want to turn off cellular data on your iPhone, you can do so by going to the Settings app and selecting Cellular. Always check your iPhone's network coverage to know what type of network you are connected to.
