1.0 out of 5 stars WARNING MAJOR SECURITY FLAW
Reviewed in the United States 🇺🇸 on 17 November 2020
Colour: BlackVerified Purchase
Product was easy to setup but once online I did a port scan to check for vulnerabilities.
Two issues make this a very dangerous modem/router
1) although HTTP (Port 80) is closed on the WAN, HTTPS (433) Port is
open and I was unable to close or block.
2) there is a published root account and password and the user is unable to change the password according the the seller (see question answered around page 4) . Only the admin account password can be changed by user.
I was able, over the internet, to access the modem configuration page, use the default root logon information to access the entire root level modem confirmation, including firewall and port forwarding. A nefarious person could reroute
all your connections to gateway and capture anything you do on the internet.
THE FIRMWARE MUST BE FIXED
Also there is no VPN supported by the modem
4.0 out of 5 stars How We Connected To Verizon
Reviewed in the United States 🇺🇸 on 3 October 2020

Here are the issues: Skimpy non-existing instructions included with device. Skimpy knowledge of Verizon people both on phone and in person at Verizon store. We overcame these little time-wasting speed bumps by doing the following:
First go to Verizon store (they should provide a free sim card).
Step1: Activate sim card on another device in Verizon store (they used a tablet).
They will try many things but they will sadly hand you back your device after failing to make it work on their network. Do not despair. Go home with gadget under your arm, and steely determination in your stride.
Step2: Put sim card in router.
Step3: Turn on router.
Step4: Use a computer,tablet,phone to
connect and then configure the device. (you need a browser)
Step5: When router appears on your wifi connections, connect to it and enter the WI-FI KEY (label on back of router).
Step6: Open a browser on your device and type in "192.168.0.1" (no quote marks, just the numbers and dots) click enter.
Step7: Click on "Login" (Upper right, next to "Refresh").
Step8: Type in "admin" for User (no quote marks).
Step9: Type in "admin" for Password (no quote marks).
Step10: Click on
Device Settings button.
Step11: Click on Internet Settings button.
Step12: Click on APN button. (Most GSM-based networks require an APN (Common Access Point) to be entered in the router to establish the final handshake between the carrier's cell tower and the modem/aircard.)
Step13: Change APN Profile name to "Verizon" (no quotes).(this is optional)
Step14: APN name must = "vzwinternet" (no quotes)(Required for general Internet connections on Verizon networks).
Note: the default
setting of IPv4 is working ok on ours, and there is no Authentication,Username, or Password.
Step15: Click Apply and modem will reboot.
If you are successful, in a few minutes (takes time for handshaking), you will see the signal strength from cell tower and little globe with up and down arrows on your screen. As well, the router itself will display the signal strength in blue bars, and the 4G/LTE arrows icon will be lit blue.
I am watching youtube videos and it is working well.
5.0 out of 5 stars This device will work on the Verizon Wireless network!

It took me several visits to find the right person at Verizon Wireless (VZW) to help me get the Yeacomm 4G LTE CPE Router set up on the VZW network.
First, the Customer Service Rep (CSR) for VZW tried to scan the IMEI; it said, "this device is not compatible with our network." Instead, the CSR activated the SIM in one of their Jetpack devices, moved it to my device, and waited for the blue up and down arrows to come on to show the VZW signal was being received. We could not get the device to work in the store.
After arriving home, I read the instructions in the box to set up the device and connected the Yeacom via my PC. The key was to add the VZW APN in the appropriate box; after that, it started to work. You can find the appropriate APN online. You should also consider renaming your network and creating a password.
I have Verizon DSL at home, twenty-year old obsolete technology. I typically get one or two bars of VZW network strength on my Yeacomm and this device outperforms my Verizon DSL service hands-down.
4.0 out of 5 stars Rural Internet replacement solution

I saw a YouTube video on how to update this router to spoof the Phone company SIM card into thinking it was in a cell phone with unlimited data. Woo. Long sentence. Now, while I recognize the moral ambiguity of this, I was intrigued with the idea.
I life in a rural area with no Internet connection whatsoever. I’ve tried several means of obtaining Internet (Satellite Internet was an expensive disaster), none of them worked. So, with my wife trying to run a business while using the limited hotspot data that comes with our phone plan and listening to her scream every time her computer dropped the connection, I decided I need to do something drastic, when along came a hotspot plan that offered a 100gbs for $50 a month. The question being would 100gbs be enough for the month?
That’s when I saw the video showing how to use this particular router as a WiFi hotspot, and with the update and one setting change, I could potentially have unlimited hotspot data (Our phone plan gives us unlimited data for our phones, not the hotspot).
So, now with a mission to upgrade our ability to live our lives as the Internet Gods intended, I ordered the SIM card and the Yeacomm P21 router. Now, let me preface this by saying my plan came to fruition and works great. The router gets better signal strength than the Phone company router and I can connect devices via Ethernet ports on the back if I want, too. The wireless coverage covers our entire 3,000 sqf house and attached garage. No WiFi extenders needed.
Now for some problems I encountered while trying to set it up: The instructions were written by someone with a limited grasp of the English language. I get it. The router is made in China (Sigh, along with most things these days and yes, I realize my hypocrisy for still buying Chinese made products), so it makes sense the translation was written by a native Chinese speaker and lost a lot in translation. Enough of that.
The next problem I had was the method of inserting the SIM card into the slot. The router accommodates three sizes of SIM cards and utilizes inserts to hold the cards in place as you insert the card into the slot. The problem is the inserts don’t hold the card as you try to insert into the slot. So, they supplied a flat metal “tool” to assist with inserting the card. Except they never explain that you need to use this tool or mention the tool in the instructions at all. After several aborted attempts to insert the card, and getting so frustrated I almost returned it, I figured out the puzzle (Insert Chinese puzzle pun here).
After that, the router recognized the card and the Ethernet connection was up an running. The wireless connection was another matter. Needless to say, after a couple hours of fumbling around, I figured out how to make everything work. And it works great! Now, aren’t you glad you read 5,000 words of a review to get to the bottom line?
4.0 out of 5 stars Make sure you have a compatible plan.

Started out as a headache. I need Internet in a remote location and thought this should work. I bought an at&t sim card from bestbuy and when the router arrived I was able to activate the sim card online. They asked for the IMEI number of the router and even though they did not recognize the device I was able to activate the sim card without much trouble. So I activated the card and paid for a prepaid hotspot plan 3gb for $25. I put it in the router and turned it on and it doesn't work. Look at the instructions for router and they are in very poorly written english(probably a rough translation from Chinese). Difficult to understand but I was able to figure out how to login to the router and change the APN. I used the APN NXTGENPHONE, broadband, and phone and each time the router would connect to the network but when opening a browser I get a message from at&t that says it looks like I have no data available on my plan. So I thought maybe it is an AT&T problem. After a couple days and multiple calls and chats to ATT I find out my "data only plan" is not compatible with hotspots (that makes no sense to me). Of course no refund even though It's only been a day and I have used no data. I have to pay another $35 for a compatible plan. ATT on the phone was no help at all. They couldn't even tell me my plan was incompatible with hotspot use, I found it on a forum online. When I paid for the new plan the hotspot started working almost instantly. I put the sim card in the phone and get about 7 MBPS. That is as good as my home internet so I'm happy with it. I live in Idaho where internet is slow. So far now that I have the right plan the router has worked well. The wifi signal is not as strong as my home internet router but it works fine. I took off a star for the lack of support from yeacomm and very poorly written instructions.
