mobile

Recently I have been experiencing problems with my data connectivity on my Nexus 5. Quite often I will try to send a text message, and no matter what it will not send, even though I have full bars. After I reboot the phone, it will show "No service" for about 5 minutes before it shows a connection. I will then be able to send and receive messages. Sometimes messages that were backed up will appear hours or days after they were sent. This happens almost on a daily basis, multiple times a day, and I am getting sick of having to reboot it all the time.

One thing I have noticed is this occurs most after I travel somewhere. So when I get to work from home I won't be able to send or receive texts until I reboot, and vice versa. It's almost as if it is changing zones, and fails to connect to the new tower.

So what I am wondering is, is this an antenna problem with my phone or my service provider? I am on Virgin Mobile in Canada, which uses Bell service towers. I have checked the coverage map, and am well in the range of 4G/LTE. I have never had this problem on other carriers, and it most recently started after updating to Lollipop 5.0.1 or 5.1 (not quite sure exactly).

Any help greatly appreciated
