I honestly have no clue, this whole naming thing got me completely confused! If I use mobile data now, it says “4G”. However, as far as I can remember, when I did the speed test with the results I posted above, it was indeed displaying “3G”. Unless I might’ve forgotten since it was indeed a while back.

I agree, the speeds don’t seem all that usual for 3G.

I would say that what you've used was a 4G-LTE (if not even a 4G-LTE Advanced) connection. The Upload speed is really that high IMHO.

Ok!.. Back to my own case. While I was rechecking my ISP's LTE bands last weekend, I got my last week's biggest surprise when I've found the following speeds:
Ping:     33 ms
Download: 92.91 Mbps
Upload:   42.83 Mbps

That was a killer!... Never got those numbers before, EVER!... Now, a bit of a background, to get my sense of all this.

My ISP has deployed its FDD (Frequency Division Duplex)'s 4G-LTE service over 2 frequency bands:
> Band 3 (1800 MHz)
my signal strength: -88 dbm.
Current data peak:
Ping:     33 ms
Download: 92.91 Mbps
Upload:   42.83 Mbps

> Band 20 (800 MHz)
my signal strength: -64 dbm.
Current data peak:
Ping: 23 ms
Download: 65.67 Mbps
Upload: 22.99 Mbps

The only thing that was holding me off the Wireless broad-band wagon till recently was the absence of the unlimited plan (as I used to have a basic ADSL cnx). Things changed recently and I did get an unlimited plan with a fair-use Clause; both the upload and download speeds are capped to 4 Mbps (this was about the speed I used to have with my ADSL plan) during working hours when the client's bandwidth usage reaches 100 GB. That seemed fair to me.

Now, you're all in the now :-)
