There are a few reasons why your phone might say E instead of 4G. One possibility is that you're not in an area with strong enough cell signal for 4G. Another possibility is that your phone is set to use 2G or 3G data speeds instead of 4G.
You'll see the E symbol when your phone is using Enhanced Data Rates for GSM Evolution, which is also known as Enhanced GPRS. This is the second slowest mobile network, and it's usually the last network a modern smartphone will connect to.
The E indicates that you're iPhone is connected to the Edge or 2G network. That will change depending on the type of cellular data or Wi-Fi connection your iPhone is connected to. If you're in a region that offers different cellular data connections such as 2G, 3G, 4G or LTE you will so those appear.
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. If not, turn mobile data off and Wi-Fi on and check again.
If 4G or LTE is available from your provider, you can switch to a 4G network in your cellular or mobile settings. If you don't see the 4G or LTE option on your Android and are sure your phone is compatible, dial #*#4636#*#* to enable the feature. Some carriers do not allow you to change your network type.

First, toggle on and off the Airplane mode.
On most Android phones, you can toggle on/off airplane mode from the Quick Settings panel. If not, you may go to Settings → Mobile Networks → Airplane mode. Turn on Airplane mode for about 30 seconds or more. Turn it off again to reconnect your network.
Letter E stands for EDGE (Enhanced Data Rates for GSM Evolution). It is also called Enhanced GPRS. This technology lies somewhere in between 2G and 3G technology. So, we refer to it as 2.5G.
The “E” symbol on your iPhone's status bar stands for “EDGE,” which is basically 2G service. By today's standards, EDGE is very slow, and you must be in an area that doesn't offer 3G or LTE service.
First, check to make sure that mobile data is turned on. You can find this setting in the "Wireless and networks" menu. If that doesn't work, try restarting your phone. If you're still having problems, you may need to update your carrier settings.
The 4G Network lets you have the fastest rates and provides a fast connection while the E network is the slowest connection. However, true network quality depends on the congestion and the coverage.
Reset network settings
This is an extremely important solution to follow when cellular data fails to work on your iPhone. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Once this completes, cellular data should work like a charm.
It might be that the area you are in gives only a weak 4G+ hence the drop to 4G. Most carriers have maps detailing the coverage and strength of each network on their website so checking there might help. You should also consult the carrier for this problem as they might do better in helping you.
Enter the Cellular Data Options section. Hit Voice & Data. 5G Auto switches between 4G and 5G automatically. If you want to rely on 4G at all times, tap on LTE/4G.
If your iPhone 11 Pro Max keeps on losing the 4G LTE signal, it might be because of overloaded resources. This can happen when your iPhone has been running for a long time. To fix this, you need to offload the accumulated tasks on your device. You can achieve this by doing a device restart.
Open the Settings app. Go over to Mobile Network. Choose the SIM card to enter SIM info & settings. Select Preferred network type, then choose the mode you want.

Restart your device
Aside from toggling on/off Airplane mode, restarting mobile devices has been a one-click solution to various problems. “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.
Make sure that you're in an area with cellular network coverage. 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.
