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.

Have you tried a new sim card?
If you have and it's no different I would suggest it's the same problem as many are suffering all over the country with 3g network congestion.

No I haven't, is it possible it could make a difference. Had the same sim for a while now, atleast 2 years or so. How would I go about ordering a replacement?

Yes, it can make a huge difference.
The easiest method is to pop into an o2 store and they will do it for you or you can order one from CS on 202 and then do a sim swap online http://swapmysim.o2.co.uk/

If your sim card is more than 2 years old it may not be a 4G sim. Are you on a 4G tariff? You can call into any O2 store and they will give you a new sim and swap your contacts over to it. It's free to do.

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)

I assume its a 4G sim because when I am in a 4G area it shows up with the 4G icon, and when I did my upgrade they said everything was ready for 4G.

If you see the 4G icon, then you have a 4G sim. You wouldn't see it otherwise. Even so, just to eliminate the possibility of the sim having a fault, if you can easily go to an O2 store and do a swap, please do so. If that doesn't solve things and you're still having the same problems, then you can move on to try to sort out what it is.

When you go into the store they can try your present sim in one of the test phones to see if it is giving a problem but change your sim anyway, it certainly makes sense.

Anything is worth trying.

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