one bar of service

For days now, i have had only one bar of service on the mobile data network no matter where i go. Im outside-one bar, in my home-one bar, driving along the highway-one bar.

I did a speed test on my phone and it says 4.53 mbps download, and .30 upload,,,your internet connection is slow it says.

Lots of other people have had the same issue on other providers, I've looked on downdetector and other similiar sites...
