    Default Samsung S4 suddenly unable to make data connections/connections to the internet

    Hello everyone,

    Something quite annoying (extremely annoying) and confusing happend to me today. All of a sudden my Samsung S4 was unable to connect to any mobile internet network (the mobile network itself seems to connect fine). I then connected to several different wifi networks and although it connects to the network, there doesn't seem to be actually an internet connection being established.

    This happened all of a sudden and without any real explanation. I tried rebooting numerous times, taking out the battery, changing sims (same problem with both my sims US & European). Currently on a roaming network, but this wasn't a problem before.

    Also the fact that no wifi connection is working (connecting but not getting data) never happened to me before. I cleared the cache from the internet, cleared the memory cache, but to no avail. I tried to wipe the cache partition in the recovery mode, but couldn't do that (just got error)

    I have a US Samsung S4 - unlocked.

    Any help, insight would be really appreciated as I don't know what to do and this is extremely annoying as I need to be connected as much as I can

    Tom

    Welcome to Android Central!

    Well, taking your phone into the carrier is always a safe bet. However, you could always back up your phone and do a factory reset (keep that thought in your hip pocket). Helium Backup is great for backups. Pop into settings Networks -->More--> Mobile Networks (I'm wing'n it, I no longer has a Samsung phone) and take a look at your mobile network settings. Does anything seem amiss here? Everything checked that should be? You could try toggling a few settings like Network mode (or the equivalent) and rebooting to see if that makes any difference. Worse comes to worse you can do that backup (if you want) and do a factory reset.
    Live long and prosper.

    Hey Haalcyon, thanks for the advice, as the phone is unlocked it's not bound to a carrier. I can't easily take it into the shop where I bought and unlocked it as it's in Los Angeles. The factory reset might also not be an option because of that as I would then probably lose my unlocked mode, right?

    Any other opions on this or people who had this happen, my mobile network isn't even connecting to the 4G or regular data network.
    Could my internal antenna be broken or something, any way I can check this?

    Now that is a good question and one of which I don't know the answer.
    Live long and prosper.

    I had this happen intermittently with calls and data for unknown reasons. I cleared the phone apps cache and data and it's been okay since then (now I've jinxed it)

    Tried cleaning the memory cache, is there another way to clear cache (the reboot mode give me an error when I want to do it via that)

    Correction, it seems I can access the wifi networks and I contacted my provider and it seems to be a dataroaming issue. Hope it gets sorted too, at least it's not a phone problem.

    Hi there. I faced that problem today. I found that by 1. Turning off mobile data, 2. Deleting the APN 3. Restarting the phone 4. Adding back the same APN works like a charm. Why not give that a try.

    What is APN 3 and where would it be found (to delete)?
