we826GO-U, quectel EC25-AF can't get on t-mobile

[wherman]

I am unable to get my WE826GO-U on the internet

I installed the Quectel EC25-AF modem
connected antenna pigtail connecters
configured apn for fast.t-mobile.com
set time zone, password saved all

got t-mobile sim and put in apple iphone 6, connected and got on internet pulling 40 Mbps
pulled sim from iphone 6 and put sim in adapter tray
installed sim in we826GO-U

powered up we826GO-U
look at debug info

looks like dev/ttyUSB2 AT+COPS=0 returns an error code +CME Error 13

Under Modem-->Network Status does your modem show up, IMEI info filled in and SIM info?

Which plan are you using?

What mode is your modem in? QMI, MBIM, ECM?
Should say this at the bottom of the first section. If not you can go to Modem-->Miscellaneou-->AT Command Terminal and enter the command:

Code: Select all

AT+QCFG="usbnet"?

if it returns a:
1 its ECM
0 is QMI
and 2 is MBIM

[wherman]

Before I answer all your questions, it dawns on me that maybe I should configure the modem to use the IMEI number from the iPhone 6 as it is what is activated on the network. Is there a way to do that? Or is there a way to activate the Quectel IMEI, or doesn't it matter?

All this info came from Modem->Network Status

Modem :Quectel EC25-AF
Modem 1
Modem ID :2c7c : 0125

Provider :Failed to Connect : Retrying

Comm Port :/dev/ttyUSB2

Modem/SIM Information

Modem IMEI :866834040913522

The plan is a Sprint Unlimited Plus - but I am using APN fast.t-mobile.com because I went to the T-Mobile store and traded in my Sprint SIMS for T-Mobile SIMS. The iPhone 6 showed up on the T-Mobile network using APN fast.t-mobile.com

The modem says it is in QMI mode

Any ideas?

[Mattflexreed]

If it's a sprint plan then it probably uses the sprint apn, not t mobile.
And you don't need to configure the modem imei

[wherman]

i have now tried the sprint apn's. Same error. I am pretty confident that I need to use the t-mobile apn as the sim is t-mobile and the iPhone 6 it came out of was configured to use the t-mobile apn. the plan is sprint, but I have been migrated to the t-mobile network because sprint is so bad at my house. I can't find what error 13 meant in the Quectel AT command guide

[wherman]

About to give up on this and return the router, does this mean anything to anyone?

That means that you dont have a 5G modem, so its not registering on the 5G networks. Its built into the router firmware for 5G modems. You can ignore this.

[Didneywhorl]

If you swapped SIMs and the new SIM registers fast.t-mobile.com on the phone its registered in, then it should work out fine on that APN.

If you go to the command terminal again and run the command:

Code: Select all

AT+CGDCONT?

What is the output?


Also, did you set your system time?

System-->System-->Time settings, or something like that

After Modem IMEI does it Show the SIM information? If not, there's a major issue, its not reading your SIM card.

[wherman]

When I type in

AT+CGDCONT?

I get

+CGDCONT: 1,"IPV4V6","fast.t-mobile.com","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT: 2,"IPV4V6","ims","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

+CGDCONT: 4,"IPV4V6","tmus","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

OK

under modem network status it appears to read the sim info, it is providing the imsi, iccid and phone number

[wherman]

I did set the system time each and every reboot

[wherman]

i did set the system time after each and every reboot

+CME ERROR: 13


What is Error 13?

[BillA]

i have now tried the sprint apn's. Same error. I am pretty confident that I need to use the t-mobile apn as the sim is t-mobile and the iPhone 6 it came out of was configured to use the t-mobile apn. the plan is sprint, but I have been migrated to the t-mobile network because sprint is so bad at my house. I can't find what error 13 meant in the Quectel AT command guide

The CME Error 13 means that the modem is not provisioned properly for some reason. Even thought you have migrated your Sprint to Tmobile, Sprint accounts have always been problematic to provision.
Not sure if you have done it already, but I would try the sim card in a phone first, make a test call and browse the web, then insert it back into the router. You may want to reflash the router with the latest firmware
Here's the latest WiFix firmware for the WE826-T2/GO-U/MoFi dated 2020-05-16.
https://drive.google.com/file/d/1omKTO7 ... d3vAyM5Kk/
After flashing it, perform a full factory reset via System > Backup/Flash Firmware > Flash Options > Restore > PERFORM RESET.
Restart the router, set the APN to "fast.t-mobile.com", TTL to 65, restart the router, wait about five minutes then try to access the web. By the way, iPhones tends to show the APN incorrectly (though internally it's set correctly), you could try to insert the sim into an Android to read the correct APN (it may not be "fast.t-mobile.com" due to being a former Sprint account).
If there's still no connection, I would test the route with a different carrier's sim card, make sure to set the proper APN and TTL. If all else fails, drop me a line at the contact info under my profile pic.
