Does xfinity mobile plan on increasing the unlimited data cap now that 5g is available? Xfinity mobile drops data speeds after 20gigs as someone who works Mobile i tend to use a lot of data. 5g signals can easily run speeds around or over 1 gig a second. In theory you can reach that 20gig data cap in l20 seconds for the entire month if you're downloading/ uploading alot. Also now that stream gaming has become a thing I imagine even more people will be hitting that 20gig cap quickly. I would be willing to pay more for a higher data cap on an unlimited data plus or something.
