Problem #1: Samsung Galaxy S6 can’t send text to international numbers and keeps adding country code (Ireland) to number when replying to text message

I purchased an unlocked Verizon Samsung Galaxy S6 from America. I am living in Ireland and am having problems sending text messages. When I send a new text message to an Irish contact number on my phone the message will send. When that contact replies my phone changes their mobile number to + (353); It adds in the country code. My phone will not allow me to respond to this text message so in order to reply I need to create a new message to that contact. I am also unable to send a text message to any international number. — Alana

Solution: Hi Alana. Were you able to text your friends (from Ireland) without any problems before? If you did, the issue is either due to some network outage in your area, or a phone glitch.

This problem is actually not an isolated case as a similar one had been reported by AT&T users before. Here are the things that you can do to try to fix the problem:

Refresh the phone

A simple restart sometimes works wonders. To do this, simply press and hold the power button for at least 10 seconds until the phone reboots.

Clear app cache and data

The next best thing to do is to ensure that the problem is not coming from the messaging app you are using. Wiping the cache and data of the said app may work. Here’s how:

  • Go to Settings.
  • Proceed to Applications.
  • Select Manage Applications.
  • Tap the All tab.
  • Look for the messaging app you are using and tap it.
  • From there, you will see the Clear Cache and Clear Data buttons.

Tapping the Clear Data button is a virtual re-install of the app (without the hassle of downloading) so it will wipe out all your messages. Doing so would also revert the app to its factory state so if the glitch is coming from it, it should be eliminated.

Delete the cache partition

The cache partition, also known as system cache, is a special repository that holds app-specific files that are used by the system. If the cache has become corrupted for some reason, it can lead to all sorts of problems so you want to make sure that it is in good working order. This procedure can be safely done and won’t result to any loss of your personal data. Here’s how:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up, Home, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight wipe cache partition.
  • Press the Power key to select.
  • When the wipe cache partition is complete, Reboot system now is highlighted.
  • Press the Power key to restart the device.

Call your network

Now, if any of the steps above won’t fix the issue, the problem is most likely coming from your carrier (the SIM card provider). Try calling them to see if there’s any network-related problems that’s causing text messages to automatically add an extra set of numbers when replying to a text message. You can also tell them that you are having trouble sending a text message to any international number.

Problem #2: Galaxy S6 unable to send text message at home (due to poor signal)

Phone won’t send text messages when I’m at home. I am in an area with poor signal, I already know that, but I also know it doesn’t take much signal to send a text message. I have a Sprint AIRAVE installed to help with our phone calls. I really don’t want to turn off the Airave because then I won’t be able to get/make phone calls as well, which is important to me because I take call for my job. I do not have problems sending text messages from work or anywhere else.

Earlier today I was unable to send messages but my phone was due for an update so I did the update, and it still wouldn’t send.  I updated the profile and PRL and it sent a few messages but then it stopped working. I asked some friends and they said to disable the hangouts app (which was previously the only way I could get texts to send when I was at home) so I did that and it worked… for a few minutes.  I did some Googling and disabled Wi-Fi on my phone. It worked for a minute. When it didn’t work again, I turned my phone off and on airplane mode, and it worked. — Maegan

Solution: Hi Maegan. If your Sprint AIRAVE works as advertised, there’s shouldn’t be any problem for your phone sending and receiving text message, especially that calls are working just fine. Both calls and text messaging services use the same network (3G or 4G, etc) so if one has an issue, the other won’t properly work as well.

You can try to clear the cache and data of the messaging app you are using first to see how the phone behaves. If that won’t change anything, clear the system cache.

If the problem remains, proceed to factory reset. Keep in mind that factory reset is the ultimate potential solution that you can try on your end. Before doing so, we recommend that you insert your SIM card to another phone to see how text messaging works when you’re at home.

If you haven’t tried doing a factory reset on your S6 before, simply do these steps:

  • From the Home screen, tap the Apps icon.
  • Find and tap the Settings icon.
  • Under the Personal section, find and tap Backup and reset.
  • Tap Factory data reset.
  • Touch Reset device to proceed with the reset.
  • Depending on the security lock you used, enter the PIN or password.
  • Tap Continue.
  • Touch Delete all to confirm your action.

Factory reset will wipe the phone’s internal storage so make sure to create a backup of your personal data before doing it.

If doing all these standard troubleshooting steps are not helping, consider calling your carrier (the SIM card provider) and   ask for firsthand assistance as the issue may be network-related in nature.

Problem #3: Galaxy S6 text messaging app lags and takes a long time to send

Thanks for making yourselves available for questions. I appreciate that. I have an Samsung Galaxy S6. The main problem i encounter is when texting. It takes a long time to load (open) a person’s text and it also lags when trying to type a text message. In fact i keep typing and then wait for the phone to catch up. other times the send button doesn’t activate even though there is text in the box. I don’t want to have to change phones again but this is the second Samsung phone i have (i had an older version prior to this one) that continues to give me this problem. Any suggestions.

i am happy to offer more details/information if you need it.

Any help you can provide will be greatly appreciated.

Thank you. — Amnery

Solution: Hi Amnery. If this problem keeps happening on at least two phones, the issue may be app-related. Simply clear the messaging app’s cache and data and you should be okay. You can also wipe the cache partition afterwards. Steps are provided above.

Problem #4: T-Mobile Galaxy S6 has no option to attach text when sending MMS

After downloading the recent T-Mobile Android update, I’ve been having an issue when sending picture text messages. Before the update, I used to be able to simply attach a picture, then send a text message to go along with the image. Now, if I attach an image through the messaging app, the image automatically sends and I cannot add a caption.

Additionally, if I go to share an image through Gallery, it prompts me to select a new contact or existing contact. How can I return to the old attachment settings? — Sandy

Solution: Hi. This issue may be a T-Mobile specific glitch due to the firmware version now running on your phone. Try deleting the standard solutions first (deleting an app’s cache and data, wiping the cache partition, and factory reset), before calling T-Mobile technical support.

Problem #5: Galaxy S6 not receiving all SMS and MMS

I have a Galaxy S6 and have not been receiving regular text messages – only a couple were MMS, the rest were regular texts. I have tried getting a new SIM card, T-Mobile sent me a new phone and I’m still having trouble.

I have tried powering it down regularly to no avail. I have called them EIGHT times regarding this. No one seems to know if it’s a phone issue or network issue. They told me to try swapping my SIM card with a different phone – which I would prefer not to do, but will if I have to.

They also suggested to uninstall all my apps and reinstall one at a time to see if it’s an app causing the problem. That is not conducive for me as I use some of my apps every day for work. They also told me to reset the phone but this is the second S6 since March that I’m having the problem with. The only way I’ve been able to figure out that I’m not receiving texts is if someone asks me “Didn’t you get my text?”, which happened with my boss today, or if I get just a partial text and then realize the whole thing didn’t come through. Do you have any idea if this is a network issue or S6 issue??? Help is greatly appreciated!!! — Laura

Solution: Hi Laura. This kind of issue may be caused by your network as well so T-Mobile technical support must support you all the way. But just like Amnery above, this problem can also be due to problem messaging app you are using. We strongly urge you to invest some time doing a factory reset and letting the phone run for at least 2 days without installing any third party apps to really isolate the reason behind this trouble. There is no pinpoint way to identify the cause of an issue like this so wiping the phone clean and installing apps individually is the only way.

You can also do a reverse by booting the phone in safe mode to prevent third party apps from running. This way, you won’t be uninstalling things from the device first. These are the steps:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

If the problems fails to occur in safe mode, that’s a clear indicator that one of the installed third party apps is to blame.
