Hello!
I am using a RUT240 and want to start using Teal physical M2M eSIM's.
As per this (https://wiki.teltonika-networks.com/images/a/aa/1oT_eSIM-Test_Teltonika-RUT240.pdf) test report, the RUT240 should fully support eSIM functionality:
"...
The Teltonika RUT240 features a Quectel EC25-EC cellular module which supports needed SIM Toolkit(STK), and Bearer Independent Protocol(BIP) features for Remote SIM Provisioning (RSP).
While the RUT240 comes with a mini-SIM card(2FF) slot, it can easily be used with 1oT plastic eSIM, which enables you to Over The Air swap carrier profiles. 1oT eSIM improves the reliability of the Teltonika RUT240 router by making sure that you have future-proofed the connectivity.
You can configure the main router settings in the user interface, the cellular modules are controlled via AT-commands, and you will need to have access to the AT-command terminal.
..."
I have accessed the AT-command terminal on my RUT240 and the first required AT command goes through succesfully:
gsmctl -A AT+QSTK=0
CLI response = "OK"
The second command however, results in an ERROR:
gsmctl -A 'AT+QCFG="bip/auth",1'
CLI response = "ERROR"
The brand new Teal M2M eSIM's in question will not "latch" to a network when installed into the RUT240.
So it will not provision on the network for activation.
The RUT240 recognizes the SIM card as "inserted" and reports the proper IMSI and ICCID.
RUT240 factory reset/ set to default settings.
All mobile networks settings set to "auto" or defualt.
-Any ideas?
EDIT: -UPDATE-
So, Teal support responds fast!
The support desk asked me for the eID of the eSIM I was trying to get activated in my RUT240;
As I understand it the workflow works as follows:
!Brand new Unactivated eSIM goes in a device for the first time
>the eSIM "self provisions" 'automatically' onto its "Global Roaming" Network Plan (so that brand new esim's can self provision anywhere in the world)
>after latching to 'any' cell tower and provisioning as a 'Global Roaming' the user changes the APN to "teal" (no quotes)
>After this is done, the eSIM sends a "heartbeat" to the Teal Cloud servers, and the user can see that eID as "Online" in the Teal user dashboard
>The user then selects their desired Network Plan in the cloud dashboard and the freshly activated eSIM is automatically provisioned OTA (over the air) by the Teal cloud servers with the selected Network Plan.
For whatever reason, the eSIM would not auto provision onto the Global Roaming network for me. Bummer.
Teal support asked me for the eID of the eSIM I had installed in the device.
Once I provided this to support, they "activated" the eID for me on their end.
They asked me to change my APN to "teal" and reboot the device.
After reboot, the device very quickly provisioned itself onto the Global Roaming Teal Network Plan
(this was after I had done many factory resets, and rolled back my RUT240 firmware from the latest release, to the current production release, so any AT commands I had tried previously had been cleared out; that is to say, after Teal activated the eSIM on their end, no AT commands were required on the RUT240, it was literally in factory defualt configs with the production release firmware)
-WIN-
Okay, at this point, I selected my desired Network Plan in the user dashboard, clicked apply, and crossed my fingers.
Literally magic stuff.
After ~10-15 mins my RUT240 automatically provisioned onto the AT&T 'home' network (not roaming) -this is the plan I selected.
I am seriously impressed.
I asked the Teal support team if I am going to have to have them actiavte all the eSIM cards I want to use in RUT240's if I cant figure out how to get the AT commands to fire, and I will update this thread with their response.
Furthermore;
What the AT commands are actually trying to accomplish:
Enable the STK (SIM Tool Kit) embedded in the LTE modem inside the RUT240
Enable the Bearer Independent Protocol (BIP) which is required for Remote Sim Provisioning (RSP)
As I gain more info I will reply here;
I still want to find some kind of answer as to why the AT commands from the Teltonika IoT eSIM test report (literally FOR the RUT240) dont work on MY RUT240.
