How Many Types Of Mobile Networks In the USA?

Often, different mobile network service providers do not use the same technology. 
This is why phone designed for one network cannot work on another. 
Thus, the various service providers make their exclusive offer to clients.

CDMA and GSM are the most widely used cellular networks in the United States.

Generally speaking, you won’t be able to use a phone that was manufactured for the CDMA network or one that was designed for the GSM network, and vice versa. In the United States, for example, Sprint and Verizon both utilize the CDMA networks, whereas AT&T and T-Mobile make use of the GSM networks. Ting, on the other hand, utilizes a model that is a hybrid of the two. It is also compatible with the CDMA network, in addition to the GSM network.

GSM Network

GSM (Global System for Mobile) It is the world’s most popular mobile network. As stated previously, AT&T and T-Mobile use the GSM network. GPRS and EDGE are also included in the GSM standard. High-Speed Downlink Packet Access (HSDPA) enables faster data transfer on 2G GSM networks.

CDMA Mobile Network

Code Division Multiple Access It is a more recent mobile network technology with greater data transmission capacity. Verizon and Sprint Nextel are CDMA providers. The 3G CDMA standard uses Evolution-Data Optimized (EV-DO) technology.

LTE Network

Long Term Evolution (LTE) 4G is the latest generation of cellular technology. AT&T and Verizon are working on LTE Advanced Networks.


WiMAX is another new mobile technology. It is Sprint’s first 4G network and a competitor to LTE. The HTC Evo was their first 4G phone.

Mobile Network Not Available Error Fixing On Android

Fixing your Android phone’s mobile network is as easy as following these simple steps. Even if you don’t have much experience, you can use these:

1. Turn on/off Airplane Mode


If you get the error message “Mobile network not available” on your Android phone, the first thing you should do is turn on Airplane mode. If that doesn’t work, check the settings for the network.

Simply navigate to setting>Network & Internet (in some devices, it’s Connection and sharing) section.

The next step is to locate Airplane/Flight mode and turn it on and then off using the slider button there. The mobile network will be restarted, hopefully resolving the issues.

2. Reboot Your Computer to fix mobile network error

If turning on and off airplane mode does not resolve the “Mobile network not available” error, reboot your phone.

Background apps and temporary files clog memory over time, resulting in error messages like these. Restarting your device helps clear out all of this junk and restore it to its original state.
Simply press and hold the power button for a few seconds until a popup screen appears. If prompted, select the Power off option and confirm.

To turn on your Android smartphone, wait about 30 seconds and then press and hold the power button again.

3. Take out the SIM card and replace it.

If your SIM card status network not available error persists after restarting your device, you can try removing and reinserting the SIM card in your android device.

Locate and open your device’s SIM card slot. To access the SIM card on very old Android phones, you may need to remove the back cover and battery, but on most modern devices, you can use a SIM ejector pin tool.

Now gently remove the SIM card, wait a few seconds, and carefully replace it. If the network problem still exists, restart your device.

4. Firmware Upgrade

Many people ignore Android system updates because they believe they are unnecessary or because they do not have access to WiFi. The issue occurs when the device hasn’t been updated in a long time.

To avoid errors like these, it is highly recommended that you update your Android phone. To update your system, follow these steps:

  1. Go to Settings > Phone Info.
  2. Check for updates by clicking the button.
  3. Any available software updates will be displayed on the screen. Downloaded and install it.
  4. Check if the “Mobile network not available” error message appears after your Android device has rebooted.

5. Disable data roaming

When you’re outside the coverage area of your primary cellular provider, your device uses the services of local cellular network operators. In general, when travelling internationally.

When you’re already within the coverage area of your cellular plan, however, this feature isn’t necessary. Furthermore, you may be subject to roaming charges. You must disable it on your phone in this case.

The steps are as follows:

  1. Open Settings.
  2. Go to Network & Internet (or Connections).
  3. Find the Roaming slider and turn this OFF

6. Consider Changing Your Location

It’s no secret that signal reception is difficult when you’re in an area where no cellular network available. When you’re in a remote location or an insulated environment, this happens frequently.

If possible, try moving to a location with a stronger cellular network signal. Also, ask your coworkers or friends for advice. If they’re having the same issue, it’s likely that your location is experiencing a temporary network outage.

4. Get in touch with your service provider

Before proceeding to the next and final step, the best practice is that you contact your network provider and ask them why is your mobile network not available. You’ll have some peace of mind and won’t risk losing all of your important data and files this way.

You may need to perform a factory data reset if none of the above solutions worked.

  1. On your Android phone, go to Settings.
  2. Reset by tapping on Backup. (If you can’t find this option, go to Settings > System > Reset instead.)
  3. Select Factory Reset and Erase All Data from the menu.
  4. If prompted, enter your PIN and wait for your phone to perform a factory data reset.
