Why is my LTE upload speed slow?

Forgive me for the repost, I accidentally approved an answer and unfortunately I guess it closed the thread.
Ever since I switched to Fizz, I've been unable to send MMS, I thought it was because something was wrong with MMS but now I'm starting to think it's an upload issue.
As you can see my download is fast but my upload is almost 0 on LTE (it sometimes goes up to 0.03 during the speedtest). I've tried everything I can think of. I've contacted support, manually input the APN, tried the SIM card in a different phone, I tried it in multiple locations in Montreal and the north shore of Montreal, restarted my phone's factory defaults, contacted support again. Nothing does it. With such slow up speeds,, some online services don't work at all. I can't load most webpages, I can't upload pictures, I can't get traffic data on my phone to use it as a GPS.
What else can I do?
In my previous thread, Allison W. suggested that I try 3G and that doesn't work at all, no upload or download at all. As for the bands, it's a Samsung Galaxy S7 which should be compatible.


  • My model is a SM-G930U which is not listed here but it appears to support the appropriate bands
  • Alright so I just tested my phone with my brother's sim card from a competitor (I don't know if we're allowed to name competitors here but it's the big boys in blue.) Using his line I'm able to send and received MMS as well as upload data. So I'm back to suspecting there's something wrong with my line with Fizz.
