NO SERVICE

5 devices have suddenly lost connection.  We've noticed more dead spots that anytime prior on our property.  We work and live from home and this is a big deal and big issue.  We've attempted to reset everything.  This site doesn't help much because all it give is phone numbers to call, no chat function or at least it must be down too.  I cannot call in for tech support because we have no signal to call out on.  Is there anything happening to resolve these issues?  I pay a lot of money per month and do not feel as though I'm getting the service I'm paying for recently.  I just had to upgrade phones because my last phone was connecting to everyone else's tower networks expect t-mobile's. I checked their map of outages and they show no problems, but obviously there is.
