First try to change your SIM card, meaning use any other network may be your network is having issue. If so then go to your service center and get a brand new SIM.

  • Switch your mobile network settings from LTE/WCDMA/GSM to Auto. Now, wait for few seconds then reboot your device.
  • When your device is rebooted. Go to Settings.
  • Network connections.
  • Then More Networks.
  • Now Mobile Networks-> Network mode.
  • After getting in to the network mode switch back to LTE/WCDMA/GSM mode.
  • Again reboot your device.
  • This method worked for most of people so you should give it a try.

After performing all the above instruction and if your mobile data connectivity problems still remains the same. Try toggling airplane mode to get it connect. If none of this worked for you ,then go to your Samsung service center they’ll fix this problem, if not then you will get the new device.

Fix/Workaround for mobile data connectivity problems (3G/H/H+ dropping connection).


  1. I was happy to find this article b/c I am having trouble with my new Galaxy S5 (model: sm-g900F): so far it’s only connecting via H+ and the people in the AT&T store don’t seem to have any suggestions for what do about this. I started to follow your directions, but when I went into network connections I couldn’t find a LTE/WCDMA/GSM option, only WCDMA/GSM. I went into the list of possible network connections and I couldn’t find LTE listed there either. The G900F should be the international/european model if I’m not mistaken. The phone is clearly unlocked b/c the phone etc. are working with the AT&T sim; just this one problem with the data connection… Thanks for any help others can provide!

    • @metrotima:disqus you’re right. G900F is the non LTE variant, it doesn’t have LTE option. I believe that your phone is not carrier branded, but the SIM card you’re using is from AT&T. Correct me if i’m wrong?

  2. My phone has the h+ as well …. I’m using it through straight talk AT&T and the guy from straight talk had no advise for me on why the h+ is appearing … my phone says LTE on the back … so I don’t understand why I can’t get LTE … will I ever get it?

  3. I do not have the choices you mention under mobile networks on my Galaxy S5. There is no choice of “network mode.” Instead, under Mobile Networks, I have “WCDMA/GSM (Auto”, “WCDMA Only”, & “GSM Only.”

  4. Hi I think this is very late now may be. I am having issue to connect to Mobile Data I don’t get even H/H+/3G any of these. I am from Pakistan. I tried above method and others non seem to work for me. My device is running Android Lollipop 5.0. and my Device’s model is SM-G900P. Any help would be very appreciated.

  5. Just purchased my phone it’s samsung galaxy s5 g900p .the problem with my phone is that it just works on the gsm band .my phone is running on to fix the problem
