Phone switching from LTE to 4G randomly

I'm using a Samsung Galaxy S7, and noticed recently that in places I used to have no problems,  my phone has been going from LTE to 4G randomly. If I'm in a call, it appears to stay connected,  but line goes dead. Data goes to a crawl. What's happening?

Re: Phone switching from LTE to 4G randomly

@jayfoxx 

Pm does not offer this service unlike koodo postpaid and telus who has voLTE calling for their customers that operates on the 4G LTE network. Pm only has calling on the 3G network so you phone has to switch to the 3G network to take/make calls. So either your signal with the 3G network is getting interrupted causing you to drop the call or your phone is having a hardware/software issue when switching networks.

 

@sheytoon  explained how this all works in a thread somewhere that @z10user4 dug up recently so he could probably post the link quicker than I can find it.

Re: Phone switching from LTE to 4G randomly

do one thing take your SIM card out and waiting for a minute and put it back and do rebooting your phone - This one is quick and simple. Make sure your phone is off before removing and reinserting its SIM card.


Remove your phone’s battery - Some phones have removable batteries. Sometimes removing and reinserting the battery can fix certain issues. Just make sure your phone is off before you do this.

 

what is mean for Rebooting the phone means to turn off your phone and turn it back on again.

 

please make sure APN Settings On your device,

Re: Phone switching from LTE to 4G randomly

not sure what is the difference when Samsung showing 4G instead of LTE, but some phones show 4G instead but still mean LTE.

@jayfoxx 

I don't think @S--S 's post will help much....are you saying its switching from 3G to 4G LTE? Your phone will normally be in 4G LTE until you get a call then it switches to 3G to take/make a call. Try forcing your phone into 3G only in your settings and see if this improves your service. You will find that you will likely get faster data speeds in 3G but can slow down depending on network traffic.

 

Of course @Nezgar knows more about this than I do...

Re: Phone switching from LTE to 4G randomly

I forgot to mention that this usually resolves itself when I move to a different area, without rebooting. It goes back to LTE and everything is normal again. Just to be sure, I have also updated the APN settings mentioned, and it seems the proxy and the MMSC port were incorrect. Not sure if those would have been the issue though, as they have not been touched since I signed up with public mobile and this issue has only been the last week or so.

Re: Phone switching from LTE to 4G randomly

do you notice that you always in LTE or non-LTE in some particular area?  

 

Maybe it depends on the towers around you?

Re: Phone switching from LTE to 4G randomly

@darlicious 

So, when I'm not on wifi my phone usually says LTE where the signals bars are in the top of the phone. Lately, a couple places I go regularly have been switching whats displayed there from LTE to 4G, and that's when I notice interruptions. 

 

Once I move away a bit, it goes back to LTE again and my service begins to work normally. On data, i suppose i can deal with it. But today i was on a call, and it just went dead while still seemingly connected as far as my phone was concerned.

Re: Phone switching from LTE to 4G randomly

 @jayfoxx : And how do the bars look when it does that?

Maybe post screenshots of your APN so we can see. It shouldn't do anything about radio reception but at least to optimize that.

Re: Phone switching from LTE to 4G randomly

@jayfoxx , generally 4G and LTE are used interchangeably.  I have not seen a phone display 4G and LTE, just either or.  I suggest installing this app to get data on your cellular connection.  You will see a lot of geeky stats including the connection band and location of the cell tower.  I suspect if you are having slow data issues, it is because the connection is on 3G and the local network is very busy handling phone calls on 3G.

@jayfoxx 

Try toggling airplane mode on/off to get a better network connection. 4G and LTE are the same thing essentially. Does your phone give you seperate 4G and LTE choices?
