Problem 1: Galaxy S6 can’t send SMS to emails

I had an iPhone 4S for a little while and that worked great for me and then I was eligible for an upgrade. So my mom used my upgrade and got an S7 and gave me her S6. I got on my phone and made a new group text with my friends. But then it said delivered to some and when somebody texted back it made a new text with the people who received my text. I then realized it wouldn’t send to people with email instead of phone numbers even if I had a private text with them. One of my friends it failed to send to has email and a phone number and it picked his email over his number. Thanks for the help! — Nathan

Solution: Hi Nathan. The only instance wherein smartphone is unable to send SMS to an email address is when MMS service is inactive or disabled. Are you positive that you MMS is working? To do a quick test, simply send a regular text message to your own email address. Be sure that mobile data is on when sending. If your test SMS will arrive in your email inbox, then that’s a clear indication that MMS is working. If the messages fails to arrive though, you should contact your carrier so they can activate your MMS service.

Keep in mind too that if you enter at least 2 contact information for one name under Contacts app, your phone will automatically pick one as the default contact. This means that if you put an email address and a phone number under one name, your phone may have selected the email address as the default contact instead of the phone number. If your phone’s MMS is not activated, it may be the reason why you are unable to send a message to your friend.

To ensure that you set the phone number as the default, try the following steps:

  1. Open Contacts app.
  2. Select a contact with multiple contact information.
  3. Tap the arrow pointing to the right to display the available phone numbers and emails.
  4. Select the preferred default number or email.

Problem 2: Galaxy S6 can’t connect to 4G LTE network when roaming

Hi Guys! Having issues roaming in Canada. My wife and kids have had no issues (we are all on T-Mobile network) as they have Apple products… however I’m having problems properly connecting to a network to get phone calls and send and receive texts and surf the net. I had zero network connectivity. However, I fixed this issue by turning off wifi calling in phone settings, then turning airplane mode on and off…Now, I seem to get 2G but not the 4G LTE. I need to execute basically any function. Very frustrating!! 🙂 Any help would be greatly appreciated. (tried the safe mode and reboots etc) Thanks! Adam.  — Adam MacKillop

Solution: Hi Adam. Roaming is a value-added service, which means that most carriers don’t support it for free by default. A user must configure the phone properly and must have the right subscription plan to enjoy it. We don’t know the exact setup you’re in with your carrier but it would be best if you can talk to them directly about your difficulties. We don’t work for T-Mobile and we are not familiar with their Roaming service as well as the right configuration in both your device and account. It may be as simple as activating a certain code in your phone or as complicated as having to reconfigure the phone’s network settings from scratch. Each network configuration is unique so the best party that can help you is T-Mobile itself.

For example, not every place may have LTE service so your phone may be able or not to enjoy 4G LTE speed. If you have the time, kindly visit T-Mobile’s useful site for your roaming-related questions as well.

Problem 3: Galaxy S6 keeps showing callers as unknown

Hello my name is Alvin and i have recently got a new SIM card called Vaya and they have already activated and now register with them. However i am using my Samsung S6 Edge and there seem to be one problem where whenever my family or friends ring me, it always says Unknown number and instead i get a text SMS which shows both their name and number on it. Please tell me how do i fix this. Thanks — Alvin Chang

Solution: Hi Alvin. The first thing that you need to do here is to ensure that you don’t have duplicate contacts. If there are redundant or the same copy of names in your contacts list, the phone won’t be able to identify which name to display in the screen.  By default, the system will simply show the calling party as an unknown contact.

If there are no duplicate contacts at all, the problem might be caused by a bug in the Phone or Contacts apps. Make sure that you clear their cache and data. Here’s how to do that:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more.
  5. These are all clickable items. You’ll want to click on Storage.
  6. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Should the problem continue after doing the steps above, try to wipe the phone with factory reset. This will help in clearing out unwanted bugs and/or app causing the problem. Be sure to test how calling works right after you factory reset the device.

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
  8. Be sure to check if the issue remains right after setting up the phone again. Do not install any app at this point.
  9. If the problem stays even when there are no apps installed, then there may be a coding-related limitation that’s keeping it that way. This means that the phone’s software may be incompatible with your carrier’s system, resulting to calls even from known contacts as being tagged unknown.

Problem 4: How to recover missing SMS from Galaxy S6

Hello, I’m sorry to bother you like this. Unfortunately, THIS IS AN EMERGENCY! I have set the emails of two persons, on or about February of this year, maybe before, that my phone keeps ALL the texts no matter how many! Now, I can only find the texts from August of this year! I need those texts from before! It’s for a court case! I HAVE to be able to prove the abuse! PLEASE help me! Thank you! — Debby Donner

Solution: Hi Debby. There’s nothing much any one can do to help you at this point. Text messages are usually kept locally by default. This means that they are only saved in your device and not anywhere else. If you are using the native Samsung messaging app and you did not set your phone to automatically create a backup, like what a Samsung Cloud feature can do, you’re out of luck.

Some carriers can keep their customer’s text messages for some time however so if you need those SMS/MMS as evidence in a court, you should be able to legally request for them. You should employ the help of an attorney to do that.

To see if you set your phone to create a backup of your messages before, you can go under Settings>Cloud and accounts>Samsung Cloud>Backup settings. If you did allow Samsung to back your stuff up before, you may be able to recover your old SMS by simply going under Settings>Cloud and accounts>Samsung Cloud>Restore.
