S5 Can’t Connect To Mobile Data

Problem: Just installed a new screen as old one was broken. Phone still worked fine but hard to see with broken glass. When repair was completed (no problem) phone started right up and looked fine but date and time were wrong. Reset those and tried to use phone. I can call but when I text it doesn’t show up on my phone. I also can’t get internet even though it says I am connected to my home wi-fi. Can’t connect to mobile data either. I have service with Straight Talk. Please help

Solution: Since this phone underwent a repair prior to the issues occurring then it’s possible that a component in your phone may have been affected during the repair process. Try to eliminate any software related problems first by backing up your phone data then doing a factory reset. Once the reset is done see if you can connect to your home Wi-Fi or your mobile data.

If connecting to your home Wi-Fi you need to turn on the Wi-Fi switch of your phone then connect to the network. You will probably need to input the network password first if you have a secured connection.

If connecting to your mobile data connection make sure that the Wi-Fi switch is off and the mobile data switch is on. If your phone does not have the correct Straight Talk APN settings then you need to make sure that it is set first before you can connect to the Internet.

You should also check if you can now view your text messages.

If the issues still persist then I suggest you bring your phone back to the repair shop and have it checked.

S5 Doesn’t Automatically Switch To Mobile Data

Problem: When I leave my house, where it has been using wifi, my phone rarely switches to data mode unless I turn airplane mode on, then off — then it finds my data connection. This behavior happens whether or not I have the Smart Network Switch on or off. It also happens whether or not I have wifi on or off when I leave the house. My carrier is Airvoice, which uses the AT&T network, but I don’t think it is an Airvoice issue since sometimes I don’t have this problem. My husband has exactly the same phone and the same service and also encounters this problem. It has me stumped! I haven’t been able to find any info on how to solve this. Any help you can give would be most welcome.

Related Problem: I am having issues with mobile data when the connection to a WiFi network is on. For example I am out of the house all day using 4G. When I get home the phone automatically connects to the WiFi network. However, when I leave the phone will not automatically switch to mobile data unless I restart the phone. This has been happening a few months now, after an update was installed. I assumed it was a glitch and a patch would be issued but there is nothing as of yet. How do I sort this issue?

Solution: This problem is usually caused by some form of corrupt temporary data in the phone. The best way to deal with this issue is to start your phone in recovery mode then wipe its cache partition. This procedure delete the temporary data stored in your phone. Once this is done restart your device then check if the issue still occurs.

In the event that the problem still occurs then try to check if an app installed in your phone is causing this by starting your device in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are disabled. Try to check if switching between a Wi-Fi connection and a mobile data connection proceeds without any problems. If the issue does not occur in this mode then an app you downloaded could be causing this. Find out what app this is and uninstall it.

If the above troubleshooting steps fail then I suggest you backup your phone data then do a factory reset.

S5 Can’t Connect To LTE

Problem: I have an AT&T Galaxy S5 (SM-G900A) that I unlocked and ported over to Ting (which uses T-Mobile’s network).  I have an APN setting recommended by Ting (https://help.ting.com/hc/en-us/articles/205428698-GSM-Android-APN-Settings) and have been able to get only 2G data.  I tried the settings you recommended here: http://thedroidguy.com/2015/07/how-to-fix-samsung-galaxy-s5-network-mobile-data-wi-fi-problems-108616, with the same result.  For what it’s worth, my phone is rooted, and I had no issues getting 4G on AT&T.  I’ve traveled around my area, all of which is supposed to get 4G LTE from T-Mobile, but I have yet to get anything other than 2G.  I work out of my home, so 95% of my usage is WiFi, therefore this is not a show-stopper.  But I would like to be able to get 4G. I’m still working with Ting, and they’re now suggesting a factory reset.  Per the information on your site, I thought I’d check with you first to see if you had other suggestions.  Thanks in advance for any information you may have.

Solution: If there are no issues with the account connecting to LTE and the APN settings of your phone are correct then you should go ahead and try to do the factory reset as suggested by Ting. Just make sure to backup your phone data first since this will be deleted in the process.

S5 Verizon Not Able To Access APN Settings

Problem: Hello, I am currently trying to use my Samsung S5 (verizon) with my new straight talk plan. I try to add the Straight Talk APN but my phone does not allow me to add a new APN, everything is locked down. Will the directions given on your troubleshooting page on clearing the cache and performing a factory reset fix this problem? I appreciate any help you can provide.

Solution: Is your phone unlocked? If it is then you should be able to use the Straight Talk SIM on it. Accessing the APN settings on a Verizon S5 however can be tricky since this is usually locked down by the software. Try to backup your phone data then do a factory reset. Once this is done check if you are now able to access the APN settings of your phone and make the necessary changes.

If the issue persists then your other option is to flash an unbranded stock firmware on your device. To do this you will need a copy of the firmware file and the latest version of Odin installed in your computer. Instructions on how to do this can be found at several of the popular Android forums online.

S5 Not Connecting To Mobile Data After Factory Reset

Problem: I performed a factory reset on my galaxy s5 and now I can’t get my 4G network. .. can only use wi-fi

Solution: The APN settings of your phone may have been deleted during the factory reset. Try to check your phone APN settings then make the corrections if necessary.
