Upgrade from Internet Lite to Unlimited

I'm in a rural area of NC and have had the "200GB Internet Lite" for about 5 months now (this plan costs $100 per month).  I was able to switch to the "Unlimited" plan for $50 per month and wanted to relay my experiences in doing that so as to maybe help others.

Even though I requested thru the TM web site that I be notified when "5G" became available in my area, I never received any notification.  Still, I would occasionally go to this website:

Verifica la elegibilidad para Internet 5G | Internet 5G residencial de T-Mobile

and see if 5G had become available "just in case" TM wasn't telling me.  I do speed-checks of my service pretty regularly and noticed about 3 weeks ago that they seemed to improve significantly, and my router was occasionally connecting to the N41 band…..so I knew I was often receiving 5G service despite what the above link said and being > 5miles from my tower (I do have line-of-sight to it though).  Then one day the link above said "Good news...5G is available at you address".  Well, I didn't around to calling them immediately (and no e-mail from them either) and a few days later...the website goes back to saying "unavailable at my address".  So I call TM services and explained what had happened, and they checked the site above and said "it is showing as unavailable at your address".  I pressed a little harder saying I was getting the N41 band and it showed as "available" a few days ago (and didn't call then because I was busy) and the rep checked the tower and told me it did support 5G and would change my plan over.  Today is the first day of my new billing cycle and I can confirm that the switch was made and I now have 5G Unlimited.  I'm a happy camper.  I'm the only one of my neighbors that has internet this good.

In any case, my advice to those with "Internet Lite" plans is to check the above link regularly and don't rely on a TM e-mail notification.  I would also check the TM app and see if you are ever connecting to the N41 band.  Be persistent and maybe you can save a bunch of $ and remove that pesky data-cap.
