I have no service on an Android phone. What’s wrong?

You are not alone on this ship! Many individuals face this problem and I know how this small error can disrupt nearly all the functions of a smartphone. So here I bring some amazing fixes that have worked out for me and my colleagues on Samsung and other Android devices.

Top 6 Fixes For Android Device Showing “No Service and Signal”

Fix # 1: Restart Your Device

The easiest and the first thing that you must do is restart your android device. It is proven to be a very effective method for solving numerous Android problems and bugs. Restarting the device will clear the random access memory, and reset any processes that may be interfering with optimal device performance. Simply hold down the power button for a few seconds and it will manually shut down. Once the phone is off, push the power button to turn it on again. Check to see if this resolved the issue once it boots up.

Fix # 2: Toggle Airplane Mode

Another way is to switch on the airplane mode by either going to the settings menu or by pulling down the notification panel. After a few minutes, switch off the airplane mode. By doing so, you will manually disconnect your device signal from the tower and then attempt to reconnect it. This method will reset the device’s APM-Cycle in case it has lost connection to a signal tower.

Fix # 3: Select Your Network Provider Manually

There is a possibility that your device is facing trouble finding your network provider. To assist your device simply enter the settings menu, go to mobile networks, then to network operators, and select your mobile network provider. This might fix your problem.

Fix # 4: Run Ping Test

All you have to do is dial in the following number in your phone’s dialer. Open your dialer and input the following digits: *#*#4636#*#* to enter your device’s service mode. A menu will come up with some options. You’ll want to locate your device information here and then select “Run Ping Test.” Once the test ends, navigate to the bottom of the menu and ensure that the radio data is active. Lastly, restart your device and check if your issue is resolved.

Fix # 5: Check If Your SIM Card Is Properly Placed

Switch off your device and remove your Sim card. Clear it with a microfiber cloth and replace it properly in its right position. Switch on your device and see if the issue has resolved.

Fix # 6: Factory Reset Your Device

The last resort, when all the above fixes fail, is factory reset. It is true that factory data reset clears all your data and is not considered ideal but it is one the most effective method to solve majority of the Android/Samsung issues. So whenever you plan to factory reset your device it is highly recommended that you create a backup of your device somewhere safe.

I hope my answer helps you solve the issue of “No Service and Signal” on your Android device.

How do I fix the problem of an error while searching for networks on an Android?

If in case the problem is with a Samsung phone;

This problem is caused by your SIM card not placed properly, hence, the mobile not available on network error may also occur. To fix this issue navigate to:

  • Settings
  • Mobile network settings
  • While you are in mobile settings, you have to hold the power button and the home buttons together until your device turns off.
  • While your Galaxy is off, gently remove the battery
  • Press the home button and the power button 10 times together
  • Then, Press and hold the power and home button for 1-2 mins this will drain all static charges
  • Insert your battery
  • Boot up your Samsung galaxy with the SIM Card
  • Do not attach the back cover yet.
  • While your phone is on, remove then insert the SIM card 3 times.
  • You will be prompted to restart your phone.
  • Restart your phone and you will no longer see the error while searching for network.

How do I boost my Wi-Fi signal strength?

Wi-Fi networks have a range that is limited by the transmission power, antenna type, the location they’re used in, and the environment. A typical wireless router in an indoor point-to-multipoint arrangement using 802.11b or 802.11g and a stock antenna might have a range of 32 meters (105 ft).

Here are some quick tips to maximize your signal strength and minimize interference.

Improving WiFi reception at home.

  • Put large furniture along the exterior walls of your home. Signals that don’t have to travel through large, cumbersome furniture will make reception better.
  • Minimize mirrors. All metallic surfaces reflect WiFi signals, including the thin metal layer found in most mirrors.
  • Place your router to maximize effectiveness. Where you place your router has a lot to do with how it performs. When placing a router, consider putting it:
    • Near the center of the house, on a top floor. Radio waves best travel down and laterally.
    • Off the floor, ideally on a wall mount or high shelf.
    • As far as possible from your neighbor’s WiFi router.
    • Away from cordless phones and microwaves, which operate on the same 2.4-GHz frequency. (There are some cordless phones that are WiFi friendly).
    • Away from power cords, computer wires, microwaves, baby monitors, and halogen lamps. These wires and waves can interfere with radio reception.
  • Make your reception even bigger with a repeater or a wireless bridge. If your office is inconveniently far from your wireless access point, and you find yourself stretching to the edge of the room to get better reception, install a wireless signal repeater. Wireless repeater extend your coverage without the need for more wires or hassle. Place your repeater halfway between your access point and your computer for an instant boost.
    • A wireless bridge (also called an Ethernet converter) is used to get better reception for wired devices. If you’re having trouble getting reception on your wired devices, try the Ethernet converter for a few extra bars.
  • Change from WEP to WPA/WPA2. WEP and WPA/WPA2 are security algorithms that keep hackers from breaking into your network. The only problem is that WEP (“Wired Equivalent Privacy”) is a lot less secure than WPA/WPA2 (“Wireless Protected Access”). So if you’re still running your internet through WEP instead of WPA/WPA2, consider changing so that unwanted forces don’t break into your network.
  • Limit the number of devices your WiFi will support with MAC addresses. The fewer devices your network has to support, the stronger speed you get out of it (Usually). Limit the number of devices can access your network by creating a device access list of MAC addresses. A MAC address is a “Media Access Control” identifier for devices that you and your family use.
    • Create a device access list of MAC addresses by first finding your device Mac address, and then by going to your access point’s configuration screen and setting which addresses get the green light.
  • Don’t publicize your network’s name. If you don’t want other people from potentially mooching off your signal, don’t let them know it’s there in the first place. (It is possible for software to locate “hidden” networks, but the point still stands.) Go to your access point’s admin page and uncheck “Enable SSID Broadcast.” You can still access your network, of course, but it won’t be discoverable when a computer is looking at the list of available networks.

Using kitchen foil(first hand method).

  • Use aluminum foil. This will reflect the wireless signals from your router.
  • Before you begin, go to your Network and Sharing Center on your computer. Click the name of your WiFi. It should bring up another window. Check your speed/mbps and keep note of the number that is displayed (I.E. 72.2 mbps). Once you have done that, tear off a sheet of foil that is around the size of normal printing/copying paper (8.5 x 11 in.).
  • Curve the sheet of foil. If you want to make it easier/quicker, just wrap the sheet around the label area of a 2 liter (0.5 US gal) soda bottle, and hold it there for about 5 seconds. Unwrap it and it should be curved.
  • Place the curved sheet of foil on its side (where it’s standing up horizontally) behind your router.
  • Now check the mbps/speed to the Network and Sharing Center. It should be faster than the original speed before you placed the foil behind your router.

While Traveling.

  • Set the adapter settings to maximize coverage (i.e., Power Management. to Maximum, Transmit Power to Maximum, and Throughput Enhancement to Enabled).
  • Turn off your adapter if no WiFi can be found anywhere. When you reach a town, turn it back on. You will seem to find WiFi everywhere. Whether or not you can access it will be another thing.
wifi boost

Besides, there are Wi-Fi Boosters and Extenders. WiFi Range Extenders boost the existing WiFi in your home by receiving the wireless signals from your router and repeating them with powerful amplifiers and antennas, extending your coverage by up to twice the range. They are universally compatible—so they can boost the WiFi of any standard router from any brand, even the one you got from your service provider.

WiFi Boosters take only a few minutes to install and can give you complete home WiFi coverage. It’s best to place the extender halfway between your router and the dead zone. Your signal strength and bandwidth will be immediately boosted and directed to the WiFi trouble spot.

For optimal performance you should at least match the WiFi speed of your new extender with your existing router’s WiFi. For example, if you have a dual band AC1200 router, choose a dual band AC1200 extender to maximize the boost in performance and range.

Thanks.
