I have poor / break internet connection on my phone and I want to know it is ntural or there is a problem on my phone.
I lose / break time to time my connection or signal and because of that I am thinking to change my cell phone service provider.
I have a unlock factory Samsung galaxy s III .
I hope hear from you soon.
Losing reception could be 'natural' depending on your location. I lose reception when take the elevator or go walking in the woods. I lose reception in my basement as well. I also get really weak reception when I go riding up north (near Tremblant, Quebec). I get few bars in some clubs and I never get reception in the subway. These are all 'natural' occurrences.
In what city are you located?
Losing connection is very dependent on where your phone is located. Even in your own home there will be spots where you cannot get a reception (basement).
Since you are using a Samsung S3. I assume your phone is using the LTE 2100 bandwidth only. I would suggest you get the Fido Samsung S4 as it has both LTE 2100 and 2600, its very possible it will reduce the frequency of your disconnections.
