Introduction

If your Android device displays a "No Service" or "Searching" message, or can't connect to your cellular network or cellular data, the following steps may help resolve these issues for you.
Android

1 Enable Cellular Data

Enabling Cellular Data allows your Android Smartphone to tap into the data you pay your provider for. If this is turned off you may not get a connection to your provider at all.

Make sure that you're in an area with cellular network coverage. If you're not within range of your network you may not be able to access your cellular data or you may be charged roaming fees. Check with your cellular provider to determine if you are in an area covered by your cell provider.

Domestic Cellular Data

  1. Open Settings on your phone or tablet.
    Android Settings.
  2. Select Data usage.
    Settings with Data usage highlighted.
  3. Make sure Cellular data is turned On.

Roaming Cellular Data

If you are out of the country, your cellular provider most likely charges much, much higher rates. Please check with your cellular provider to determine what prices to expect, before you travel.

By default, your Android device disables roaming data, to prevent you from getting really large bills for your data use. If you wish to enable data while roaming, continue below.

  1. Open Settings on your phone or tablet.
    Android Settings.
  2. Under Wireless & networks, select More.
    Settings with More highlighted.
  3. Select Cellular networks.
    More wireless and network settings with Cellular networks highlighted.
  4. Set Data roaming to On.
    Wireless and networks with Data roaming highlighted.
  5. Decide to enable roaming or not.

    As a final reminder, turning this feature on may incur significant charges on your cellular bill. Select OK to proceed.
