How to resolve Mobile Data problem on Android

Mobile data, mobile data, whatever you want to call it, is one of the things that only become necessities of life once you get your first smartphone. Only when you lose connectivity that you realize you do not know how to get anywhere without Google Maps, does not have anything to read without Flipboard, and do not know how to communicate with people through other media of WhatsApp.

When Mobile data stopped working on Android, it is the world against itself, in other words. Here are some tips on how to get it back.

Reset your phone Connection


A simple and powerful networks to improve data that does not work on your Android device is to incorporate SCRTN (Special Code Reset Network). Note that this fix will only work on phones using the CDMA network. In the US in 2019, this network Sprint, Verizon and US Cellular.

Assuming you with a CDMA network, go to your phone’s dial pad and enter the following code, depending on your device:

  • Google Pixel, Moto G4: * # * # 72 786 # * # *
  • Nexus 5, Nexus 6, Moto G5: # * # * 72 786 # * # *
  • Other Android phone: ## 72 786 #

Note that phone carriers are slowly trying to phase out the CDMA network as they strive to move fully to faster, newer LTE standard, so that a specific fix may not exist for it any longer.

Enable Network Mode Right

Starting with the simplest solution, it is possible that during the update, or just a phone default setting, mode network (3G, 4G, etc.) from your mobile phone is set to the one that does not offer optimal coverage.

If you have a 4G phone, for example, you should always ensure 4G is selected in your network mode to capture those sweet 4G rays. Or if your phone is not 4G, but you run the OS that features a network mode (with roots, for example), your phone might try to connect to the 4G signal that it is not capable of.


Changing. Go to “Settings -> Mobile Data -> Network mode,” then switched to the one that best suits your phone. As my phone is 4G, I went for 2G / 3G / 4G Auto so that it always tries to connect to the best available signal.

Remove and Re-Insert Your SIM Card

Some will scoff at the very mention of suggestions such as “reboot your phone” and “remove and reinsert your SIM card,” but this should always be the first port of call when trying to fix the problem of mobile data. Another option is to test your phone with another SIM card to see if the problem comes from the card or phone.

There is also an extra little tricks to reboot your phone that can help:

  • Before reboot, turn on Airplane Mode
  • Wait 30 seconds, then turn Airplane Mode off
  • If you still do not have the data, changing the return flight mode, turn on your phone, wait a minute, turn your phone back, turning airplane mode on, wait for thirty seconds, then turn on.

If of mobile data fails, then try the following fixes.

Organize your APN

Access Point Name (APN) is the means by which mobile network provider you connect your phone to the mobile Internet. Set the phone with all the important settings such as IP address and gateway to (hopefully) keep you connected. However, this process can sometimes be wrong and require a reset. The following shows how to do it.

  1. Go to “Settings -> Mobile Data Controls / Wireless / Wireless & Networks.”
  2. Press the “Mobile Networks -> name of the access point.”
  3. You will see a list of APN (potentially with only one network at them). Tap the menu icon at the top right, then “Reset to default.”

Set APN Protocol IPv4 / IPv6

This option does not exist in the APN settings of all mobile phones, but some devices (such as OnePlus 3) gives the option to leave the field empty APN Protocol. If it happens on your network APN settings, make sure it says IPv4 / IPv6 instead. Likewise, with other devices make sure it says this is not only one of two.


Enter your APN settings manually

It is a regular occurrence sad but not for your APN settings to get out of whack after the Android software update, and if the standard reset does not fix the problem, then you may need to enter your APN manually.

  1. Go to your APN list using the method in the previous tip.
  2.  Tap the “+” icon or the three-dot menu button, then “New APN.”
  3. Enter all the APN details for your network. There’s a decent list of US, Canadian and UK APN settings here and a more comprehensive list of UK APN settings here.
  4. Save your new APN settings, then select them from the APN list on your device.

Do You Have a Mobile Data Limit?

Every Android phone allows you to customize your cellular data limit and warning when you’re about to reach your limit. It is usually not enabled by default, but maybe before you set a limit, since upgrade your tariff, and forget to update the mobile restrict your data accordingly. To check this:

  1. Go to “Settings -> Mobile Data / Data Usage” (depending on your device).
  2. You’ll see a graph that shows your data usage along with a large number of settings. Make sure your data limit in the graph according to what your network allows to drag the upper or lower limit on the graph.
  3. Alternatively, you can turn off all data limit with unticking the “Limit mobile data usage” box.


There it is – the key to get you back online just when you think you should start to switch to paper maps and letter pigeons to communicate with people.

Of course, it would be ideal if there was a single, universal fix for a problem with your phone’s data, but the tech world just is not that simple anymore. If you have tried all of the above but you still can not connect, then you should contact your mobile operator to get a new SIM card.
