Ah My Daer Netizens .....
As is sooften the case, my answer is
1) "It Depends" and
2) Your milage may vary
The speed of loading webpages depends more upon your connection to the web, then your device, and finally
the web server itself.
The first thing to look at, as John Spartan tried is "look at other pages"
When "other people" report no problems then it is usually at the user end.
If "other pages" work fine it is possible the "other pages" are cached and thus dont need to load completely.
I usually look at 1) the device, then 2) the service.
If an android , download and run an app called CCleaner. It is available in a free version
and cleans out ra, excess crap, andsone other bad juju
If it is your service, there ARE TWO MAJOR ISSUES: WiFi and Cellphone, and throttling .
One needs to see WiFi will always be faster, surfing via cell connection is as slow as you state.
Lastly, the service may be throtlling your connection.
The only way to troubleshoot all this is to have multilpe devices with multiple connection and
my little 'toolbox on a thumbdrive" with tools for troubleshooting.
BTW now that I am retired, I charge nothing if I really really like you,
$200 per hour if I am on the fence about you and
$600 an hour portal to portal if I dont care for you much at all.
if I hate you , well , you can guess.
Hope this helps,
or at least gets a chuckle
