Help! Before I open the box, is it true this T home internet will replace my Spectrum service or should I return it.? I'm hearing negative reviews!

Overall, you'll need to ask what your needs are and if TMobile may be the right fit for those needs.  It should have a trial period and you may be eligible for some extra $ for converting, so what is the concern?  Potentially, yes, this may allow you to replace Spectrum, you must have reasons for even considering it.  There are always people that have negative reviews, and people that have very positive reviews.  My advice would not to let fear rule you, but at least approach change with an open mind.

The wording for "congstion" situations exist in all of the service providers, so this is normal. I have a few streaming services for entertainment, but do not stream TV regularly, so that may be a question to ask a rep or see if anyone actually knows of a services that this would fall under (if you care)… I had the rep on the phone for a while, and the persone was great in answering all of my questions about all sorts of things, but I did not ask about streaming live tv.  I have had issues with Xfinity-who likes to raise the rates, and I know people that have even more issues with Century-Link, and no other viable options until now.  I would save $8/month, but at the moment, it looks like I would be more than tripling my speeds, not that I actually need it but I am tired of Xfinity's tactics or telling me there are no outages, when I am clearly having an outage.  From my understanding, TMobile gameplan is not to oversaturate an area, but there are always risks.  True 4/5G data maximums rated for extremely high data, but what any cell provider gives you for your phone is no-where near what is actually possible or even these speeds that they are offering for home.  If they do this right, it should be very good… of course, you can always go back if you had to.  The one main point to remember with bandwith/speed or "slow" internet, more often it is actually the website you are trying to go to.  I have had evening where Netflix would have slow/loss of the connection, but my internet is still fine and I just move over to something else.

As for my actual experience, I've only had the gateway for a week.  Finding placement was easy enough and it was painless to set it up initially.  I hooked up my Ring doorbell without issues, integrated my mesh APs into this with minimal effort. Granted, I do work with computers, but the instructions were very simple, and there are videos online to help you out for just about everything else.  I've been getting consistent numbers, and just got this speed test while streaming 3 different videos,one from Disney+ and no hick-ups or apparent loss in speeds.  I am still going to test for a little while, but I haven't come across any negative issues yet that makes me want to send it back.
