Samsung Galaxy S7 Edge - "Mobile Network Not Available"

HELP! My Samsung Galaxy S7 Edge worked perfectly until a few days ago, when text messages stopped sending. Then incoming/outgoing calls failed. Have tried the most commonly recommended fixes (airplane mode off, rebooted phone, checked for software updates; reset network settings, removed SIM card and rebooted, cleared cache in safe mode, etc.) Nothing worked. Want to avoid factory reset if possible. Suggested fix, please????

33134. I don't believe it's a Network signal issue; my family are on same AT&T plan; they have iPhones and no issues.

Thank you for the reply, @TechAmNot!

 

Our sources show no immediate service interruption in your area. If you haven't already, try reestablishing connection to the service by performing a soft reboot of your device by powering the device completely off, then after several minutes, power your device on again. This action clears the memory of your phone thus fixing most minor issues.

 

If your issue persists despite the first step, use our Device Support tool to resolve your issue. Simply select Connectivity then Signal & cellular data and follow the steps as prompted.

 

Hope this info helps.

Tried Device Support Tool. Connectivity/Signal Data response: "We hit a snag. The system is currently unavailable. Please try again later." Tried it again later. Same response.

Hello @TechAmNot!

 

If you're trying to access the Device Support tool on your phone make sure to clear your cache and cookies in your browser, close your browser, then reopen your browser and try accessing the Device Support tool again.

  1. Open your browser.
  2. Tap the menu toolbar.
  3. Select History > Clear browsing data.
  4. Choose a deletion time range or the specific items you want to delete.
  5. Select Clear data > Clear.

Also, if you're at home trying to make and receive calls and text messages, try resolving your experience by disabling cellular data:

  1. Swipe down from the Notification bar, then select the Settings icon.
    Note: Mobile data is on by default. Turning off the mobile data will not allow any data to be transferred over the wireless network. Wi-Fi access, voice function, and standard text messaging are still allowed. You can also turn data on/off using your myAT&T account. Learn more about disabling or activating AT&T Mobile Share member’s data usage by device.
  2. Select Connections.

  3. Select Data usage.

  4. Select Mobile data.

  5. Select the Mobile Data circle.
    Note: When turning Mobile data off, you will receive a prompt. Select TURN OFF.

Let us know how this worked for you.

Tried the above suggestions. No difference. Still no mobile network connection.

We appreciate the update, @TechAmNot!

 

One other step to try is to partition your cache.

  1. Power off your device.
  2. Press and hold the Volume Up key, Home key, and Power key simultaneously.
  3. Release all of the keys when the Android System Recovery appears on screen after the phone powers back on.
  4. Press the Volume down key to scroll and select Wipe Cache Partition.
  5. To select your option, press the Power key.
  6. Press the Volume down key to highlight yes. Press the Power key to select.
  7. When the Wipe Cache Partition completes Reboot system now will be highlighted.
  8. Press the Power key to restart the device.

Also, does your phone's SIM card work in another Samsung phone (assuming you have access to one). If not, now's probably a good time to replace it.

Did that previously (wipe cache partition). No difference. Do not have another Samsung phone to try SIM card.

We suggest replacing your SIM card, @TechAmNot.

You can visit an AT&T Retail location or log in to myAT&T and place an order there. If the problem continues, the next step will preforming a factory data reset. Thank you for posting.
