[Q] Gs4 Network Problem

Can someone help me to fix my gs4's Data Connection . I can only make calls when i choose Gsm only. but when auto connect Lte/3g/gsm and wcdma only. no signals on my unit. What should i do. TIA peeps:crying:

is there a possible way to activate lte only?

is it possible to activate 4g only on our devices because the switching between 4g 3g sometimes makes connection lost in the process .
You can't use 4G only because you will be unavailable for calls. 4G only you can use only if your carrier supports VoLTE.

LTE only/4G only is available on marshmallow beta B511 and on Kitkat firmware (however, in KitKat, it is a hidden option which you can access by installing 'Advanced Signal Status' app in Google Playstore. For Lollipop, it is not possible to have 4G only/LTE only mode unless your phone is rooted. When LTE only /4G only is activated, it will remain on that setting even if you restart your phone. You have to get into the settings again if you want to be back to 3G or other network modes. When LTE only/ 4G only is activated, you will not be able to receive any phone calls. Only text messages will be received.
it is possible.... just watch this video in youtube: Mobil Data 2g 3g 4g Switch Only Root
but you have to be root
regarts!
