T-Mobile Connection Issue

[Joe43wv]

I'm trying to get a NEXQ6GO-M with Quectel EM06-A Modem to connect to T-Mobile but am running into a roadblock. Here are my settings:

APN: fast.t-mobile.com
TTL: Tried both 64 and 65

WAN1 Port: MBIM

WAN1 is showing the following error: Error: Unknown error (NO_REGISTRATION)

I've tested the SIM card and the sim card is working just fine. Any thoughts on as to why it's not connecting?

How are you testing the SIM card? Putting into a phone? What kind?

[Joe43wv]

Yes, iPhone 6S Plus.

If it works in a phone but stop working the moment you put it into the Modem, then it's not a compatible plan.

What's your plan?

[Joe43wv]

It's on the T-Mobile Essentials plan.

essentials only has 3G for hotspot, that may be part of the issue.

WAN1 is showing the following error: Error: Unknown error (NO_REGISTRATION) may be the network denying you though, without even trying.

Look in the Status-> System Log and do a search for "MBIM" to find all the modem messages, when the modem is in MBIM. If the modem is in QMI then search for "QMI". (Without the quote marks in the search)

Did you turn off the APN autoload that the EP06A does?

AT+QMBNCFG="AutoSel",0

then

AT+QMBNCFG="Deactivate"

Check the APNs set on the modem with:

AT+CGDCONT?

Also make sure you are setting both TTL and HL

Would switching to QMI resolve the issue or should I keep it on MBIM?

[Didneywhorl]

Ive had better luck on mbim, but it wouldn't hurt to try

[Joe43wv]

I've lost the AT commands to switch it back and forth to QMI and back to MBIM, could you provide me with those please?

Quectel Set Connection Modes

Code: Select all

AT+QCFG="usbnet",0

MBIM

Code: Select all

AT+QCFG="usbnet",2

For Quectel Modems:

QMI
AT+QCFG="usbnet",0

MBIM
AT+QCFG="usbnet",2

It definitely is. This plan is not meant to be used in a hotspot

It's on the T-Mobile Essentials plan.

Sorry, this plan is not meant to be used in a hotspot.

If you chose this plan because it's cheap, look at my latest post to get Magenta Max for $45/mo

[Joe43wv]

Update: I checked their bill and the bill is under Sprint and the SIM card is T-Mobile, does that matter what settings I use?

[Didneywhorl]

It may, but I've found previously that the APN could be just about anything with T-mobile and it would work. Not sure lately though.
