Can’t send SMS or make calls if not connected to Wi-Fi

Problem: It’s been a while since I got my cell but recently I’ve been having this issue when out of my WiFi connection I try to send a text or make a call and text and call doesn’t go through unless I un check the network connection. Once I do this text and call go through. I thought Android latest update will take care over this issue but I wasn’t that lucky. Any idea what could be causing this issues? Thanks!

Troubleshooting: It looks like Wi-Fi Calling feature is enabled or turned on in your phone. In this case, the phone will use your Wi-Fi connection to transmit SMS or make calls. Your device will continue using this service until you disabled it. It’s only then that you can be able to send texts or make calls normally. So, by now, you may already have an idea how to fix your problem–turn off the Wi-Fi Calling feature.

  1. Touch Apps from the Home screen.
  2. Touch Settings.
  3. Scroll down to Connections menu and touch Wi-Fi Calling to get to Wi-Fi Calling settings.
  4. Touch the ON/OFF switch to turn Wi-Fi Calling off and disable the feature.

Galaxy S6 Edge doesn’t have Wi-Fi Calling feature

Question: Hi! I came across your website today. It’s really good, lots of useful tips! I got a galaxy s6 edge as part of a phone upgrade with EE. However I got the phone from carphone warehouse. So it doesn’t have the WiFi calling option. Do you know if there is a way to get the WiFi calling option installed on my phone? Thanks. — Marc

Answer: Not all variants of Samsung Galaxy S6 Edge have a Wi-Fi Calling feature. Each model or variant, especially for units carried by service providers, are built according to the specifications of the carrier and everything is based on the services it offers to its subscribers. In other words, some variants have features that cannot be found in other variants.

To enjoy the feature offered by your service provider, you need to root your phone and install custom ROM that comes with Wi-Fi Calling feature. Firmware updates are based on the phone models and I’m afraid the next update for your phone won’t bring along the feature. CyanogenMod ROMs often come with complete list of features but you must proceed at your own risk as it’s not always safe to flash custom firmware not to mention you’ll void your warranty. Good luck though!

Wi-Fi Calling won’t work with other Wi-Fi networks

Problem: Hi. I was staying a week at a place where there was poor cellular, T-Mobile, service however the WiFi network i was very good and my galaxy S6 connects just fine. All apps and internet browsers work. I am unable however to make any WiFi calls or texts. The error message said unable to connect for WiFi calling. The WiFi network did not require a password and apparently this is the problem according to T mobile after having me try a factory reset which as we all know is excruciating!!! I called Samsung and they said there is nothing wrong with the phone and no nothing about why it is doing this. When I got home, I selected in my settings to use only Wi-Fi (I have a secured password network) and no cellular service and was able to make Wi-Fi calls and texts. Is there something else that can be done to be able to connect in open Wi-Fi networks too? Thanks, Heidi.

Troubleshooting: First of all, Wi-Fi Calling is still in its very early stage and there are still of lot of things to be improved. That said, you may encounter some hiccups every now and then. One known issue with this service occurs when you connect to other Wi-Fi networks with Wi-Fi Calling feature still enabled in your phone. When this happens, you may not be able to place calls and send SMS or people on the other line couldn’t hear you.

If you’ve already connected to a different Wi-Fi network and the feature is still enabled, try to disable the feature first and then clear the cache of the WiFi Calling service through the Application Manager.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap WiFi Calling.
  6. Tap Clear cache.
  7. Now, reboot your phone.

After the phone has fully booted up, make sure you are connected to the WiFi network and then enable Wi-Fi Calling. It should work by now.

But another thing that might just hinder you from using the feature is the stability of the network you are connecting to. Remember, you cannot use it when the connection is very slow, which is very much possible in your case considering the network you are connected to is open.

Wi-Fi Calling stopped working for no apparent reason

Problem: Hi. My Samsung Galaxy S6 Edge cannot send texts or make calls over Wi-Fi for no apparent reason. Ever since I bought the phone about 4 months ago, Wi-Fi Calling always worked but now it doesn’t. I’m with Sprint and I haven’t contacted tech support just yet. I’m hoping you could help me figure out what this problem is all about because I’m in an area with poor coverage. Wi-Fi is the only thing that’s reliable and I’m happy I can now send texts and make calls with it. What shall I do to fix this?

Suggestion: Call Sprint. If the feature just stopped working without apparent reason and everything else is properly set in your phone, then the problem is with your provider. There have been a lot of Sprint users who reported to have experienced a problem like yours and according to them, they just called tech support, told the rep Wi-Fi Calling didn’t work and let him/her do his/her job.

But what happens actually is that the WiFi Calling service will be disabled in your account from their end. Then, it will be re-enabled and you will receive a text message notifying you that Wi-Fi Calling has been added to your account. The service should work perfectly after that. In some cases though, it may take up to 24 hours to be able to use the service again but at least necessary actions have already been done to fix the problem. So, again, call Sprint.
