WISMO228 doesn't work with USIM

Hello everyone,
I’m using the WISMO228, about a month ago I bought a new Mexican SIMs of the TELCEL operator. The SIMs are in version 6.2 LTE.
Using the SIM in a normal 2G phone I’m able to dial and receive calls, but using the WISMO Module it doesn’t work.

I had the same problem on a TELIT module, but using the proprietary 2G AT command AT#ENAUSIM=1, I have activated the “USIM application” and now the Telit module works very well.

There is a similar AT command for the WISMO228?
It is possible to use WISMO228 with an USIM?

Thanks in advance!

As per AT command guide it supports USIM. You can find AT command guide here: http://source.sierrawireless.com/resources/#tags=WS228


Hello canforastilo,

Have you found the solution to this issue?
I’m having the exact same problem.

Best regards,

I don’t think Wismo support LTE…
