Connectivity Problems with Galaxy Note 4 on o2

[Anonymous]

Hi, I have a Samsung Galaxy Note 4 which I have had for 2 months now and the connection is terrible. Even in areas of good coverage it will drop out from time to time and during this time I cannot make calls or use data. I took the device back to the shop once and got a replacement and it still does the same thing so it's almost certainly not the handset. I also used to get the same problem on my Nexus 4 before I upgraded to the Galaxy. On the Galaxy the signal works whenever the icon in the notification bar is set to H+, but if it changes to just H the device doesn't work at all, I can't make calls or use data. Any help would be greatly appreciated.

Hi @MI5  Could I ask a question please?

I know this is more than likely to be a sim card problem but could it have anything to do with the Smart network switch?....(Just trying to learn as I go along)

Anything is worth trying.

Mine is off all the time as it gets annoying anyways.

Why does it get annoying? Is it because it spends too much time trying to sort out the best network?

(See answer a question....you get asked another one)

Just because I want to use WiFi when I can and not my mobile data.
If I was on an unlimited data plan it would be OK.

This is a well known issue. Wherever I go if I have H+ then data may work depending on congestion issues. If I only have H then nothing. The device in a H area is searching for a H+ so doesn't deliver. H is likely to be congested.

Swapping the sim may help and is well worth a try but as you had this on your nexus 4 as well I suspect it is a network issue

It's also annoying when you are on a private WIFI network, (I.E. not an internet connecton), and the phone drops it to associate with another more powerful one.
