I brought a HUAWEI E153 usb-stick/dongle in last week..
Thay said to me it can be support to 7.2Mbps speed...
but I checked in internet is it true or false...but i couldn't find that type model support to 7.2Mbps.Lots of articles mention me to Lot of E153 dongles are support to 3.6Mbps..:(
But after told that shop & I check it @ there..
While i connecting it "system tray icon" show me to 7.2Mbps dongle connected meg..
after check in "task manager" it also show 7.0Mbps..:-/

so what i want to believe "what is show me to true speed?"
how i can find the actual speed in that dongle...:-/


dongle model --> E153u-1

Short summary and likely cause (short): reported the E153u-1 showing “7.2 Mbps” in the UI. The E153 family is a 3G/HSDPA USB stick and there are region/firmware variants, so the management software or firmware can show the modem’s peak PHY capability (what it is rated for) rather than the actual usable TCP/HTTP download rate. Check the device label and the product/regulatory manual for the declared HSDPA class for your exact unit. (fccid.io)

What “7.2 Mbps” means in practice: that number is a physical‑layer peak defined by HSDPA UE categories (the modem and the cell negotiate a category). A Category‑7/8 UE is allowed up to 7.2 Mbps on the downlink at the radio layer, but protocol overhead, cell loading, backhaul limits, contention, signal quality and the Internet path reduce real application throughput — often substantially. The 3GPP HSDPA tables explain the peak/category concept and why the advertised number is not the sustained TCP download rate. (portal.3gpp.org)

A simple, reproducible verification plan (practical steps):

  1. Confirm the exact model/firmware shown in the modem UI (Mobile Partner) or on the sticker — firmware can be carrier‑customized. (fccid.io)

  2. If the stick exposes a serial/AT interface (Windows COM or /dev/ttyUSB* on Linux), probe signal and attach state: 

    AT+CSQ        // RSSI / quality
AT+CGATT?     // packet attach
AT+CGDCONT?   // PDP context / APN
AT^HCSQ?      // (Huawei proprietary: richer signal info; may return ERROR)

    AT+CSQ is standard and maps to dBm values you can use to judge radio conditions. (support.hologram.io)

  3. Run a controlled throughput test to a known server (avoid public speedtest variability). Use iperf3 with a nearby server you control (server: iperf3 -s; client: iperf3 -c <server-ip> -t 30 -P 4 -R). Close other apps, use a USB 2.0 port, disable VPNs/proxies, and repeat tests at different times/locations. Iperf gives a clearer view of raw link throughput than a web speed test. (iperf.fr)

Troubleshooting checklist and interpretation: if iperf shows ~3–4 Mbps but the UI says 7.2, that usually means the modem or cell is limited (UE category, single‑code allocation, or network load) — not a Windows display bug. Try a different SIM/operator or location, check firmware/VID‑PID, and share the AT+CSQ dBm and iperf results (time/date/server) when comparing with carrier support. Note: was correct to suggest measuring, and ’s question about “dongle vs modem” matters — treat the E153 as a modem and follow AT/iperf checks above.

Google Internet speed test and after using the test look at your download speed. Don't be surprised if it isn't 7.2 Mbps as their "up too," speed means exactly that. 7.2 Mbps is the MAXIMUM speed capable under absolutely perfect conditions. There are numerous factors that can effect and potentially slow it down like distance, interference from other radio waves, interference from physical objects whether it be walls in a building or as simple as rain outside, anyways the list goes on but I'll finish by saying that I highly doubt you're getting their "up too," speed as almost nobody does.

Until now,I did not meet that what I want...
help me to find actual data transmission rate in my dongle...

Is it a dongle or a USB modem? What do you want to find out?
