tmobile home internet speed issues

I live in a more rural area in Ft Myers FL. The only wired internet options currently are Centurylink DSL which is not very good. I decided to give the T mobile Home internet a try. I am unable to get the unlimited so am trying the 150g month plan to start.  I set up the gateway yesterday and have a full 5 bar excellent 5g connection. I only have my work computer and phone connected and I am only getting .5 to 5mb if lucky download speeds. I called the TMO rep and they said this was unacceptable speed but that there  was a ticket for cell tower maintenance going on and they would check back with me in a few days. I really want this to work as I work from home and even if I can just get a consistent 25mb download I would be happy.  This will be temporary until Fiber comes to our area. I will try and repost in a week to see if anything changes.
