China Unicom VN007+ Review

Hey Hey, it's another review time.

Today I finally got my China Unicom VN007+ 5G modem. It's been a rough journey, first order was cancelled by Aliexpress for "security concerns" (I used a revolut card). Second one went missing and is now being disputed and having little success with the dispute , third one arrived today.

speed:
12986797856.png


compared to the Huawei CPE Pro 2 I use to test everything against:

I should point out that these are BOTH well below my usual speed, so I will try again at different times. But so far, there doesn't seem to be much difference. Another nail in the £500 coffin price of the Huawei.

Pros:
Extremely cheap (£140, shipped, no VAT/customs - lucky?)
Supplied with a UK power supply, not a nasty adaptor.
More network ports than the Huawei.
Easy to flash firmwares, does not seem to be any restrictions on downgrading.


Cons:
Not much to look at, plastic is a bit cheapo but seems strong enough.
No bridge mode that I can find. There is, see below
SIM card slot is fiddly.
No WiFi 6
No SMS function without using a patched fw.

I will update this thread on the speeds and power consumption figures as time goes on. Initial findings are good, very happy with the performance vs cost.

Updates:

Power consumption:
4.7W idle (WiFi on). 3W idle (WiFi off)
7.5W downloading WiFi.
6.6W downloading wired (WiFi turned off)
These are all averages. It fluctuates.

Why is your upload speed so low compared to your download? I have similar 5G download speedtests(around 350+Mb) but an upload of around 80-90Mb. I'm assuming we are both at a similar distance from the mast?

Good question. With my phone, if I go stand 300m from the mast I see 100mbit upload. There are trees between my house and the mast which is about 700m away for the 5G ENCD one, there are two 4G masts one 300m and one 1km away.

I don't know, is the answer. The 5G mast has 100MHz bandwidth according to huactl. Traffic priority / management ? The trees in the way ? the roof tiles on my roof ?
 
I will NOT buy these Huawei 5G from China as these are spying in UK
I'll bite. Got any proof ? Besides what orange man and some former spook say without backing any of it up ? .

I mean I don't doubt it right, but the NSA put back doors in Cisco and Juniper products but most people don't seem to care about that. It's also not a Huawei product but yes still Chinese.
 
Updates:

Managed to try downgrading and upgrading firmwares, there seems to be no locking / checking you can up/downgrade as you please. Thanks to a Fillapino forum, I've managed to enable ADB , get the root password and discover that it does in fact have a bridge mode (called IP passthrough) which is ONLY available via the root password!!

So yeah, bridge mode works fine. Root PW also lets you lock cells.

This modem is super easy hackable, hoping to discover more. Will be cracking it open to fit some SMA connectors too probably at the weekend.
what does adb shell getprop reveal?

So new learnings. In addition to the 'root' user (again, different from the 'admin' user you are given on the device sticker) there is also a 'superadmin' user. You can set a password for it via ADB.

This has turned this thing into a swiss army knife of 5G. There are now dozens of options, test / engineer menus etc. Including typing AT commands directly to the modem.

Poking around on the box, it appears to run some slim android version (haven't figured out what yet but here's some interesting bits) I'm going to see if I can compile something on it :D

The firewall appears to be iptables. There doesn't appear to be any compiler, or anything I can use like python.

lulz it has VLAN support too. hidden away.

Update: It's not android at all. It's YOCTO. https://www.yoctoproject.org/
 
It's looking like a raspberry pi compute module, probably pi 3.


Even the source has rpb in it, raspberry pi b.

It's definitely not a Pi. CPU isn't right, doesn't look anything like a compute module inside. I saw that too, and yeah it says module-pi in places. Perhaps built from pi code?

But it's a UNICOM system on a chip (their own CPU), definitely not a pi with a broadcom CPU. It also has 200MB memory which I haven't seen on any pi compute modules.

Amazing. The itch is back.
Have you done any more speedtests vs huawei?

I'm absolutely loving this modem.
I'm just having fun now .... messing with the onboard http daemon
check the logo, instead of the uniocom mandarin one :D

The cables to mod it arrived today. Fitted them and it works great. I will provide some proper results soon because my antennae are not mounted yet so I was simply holding it to check. But it works, unplugging the antenna gave me no signal at all.

For now, i've let the wires come out of the grate at the bottom, I will drill some holes in the case and fit them on the case.

Sure, the store is called WLAN24-Shop

Cheers dabigm, looking on there now and they want nearly £20 shipping. How’d you get it for free!?

Maybe they've bumped up the price ? I have seen several different listings for the same device. All in all mine was £140.36 but the one I purchased originally which got cancelled was £156.10
