@ sign after Provider Name

[532910]

Sometimes, after some time, I see at sign or unprintable square at the end of provider name:

cellgate*CLI> dongle show device state tele2
-------------- Status -------------
...
Provider Name : Tele2�
...

cellgate*CLI> dongle show device state tele2
-------------- Status -------------
...
Provider Name : Tele2@
...

This is expected output:
cellgate*CLI> dongle show device state tele2
-------------- Status -------------
...
Provider Name : Tele2
...

sometimes dongle cmd tele2 reset helps
sometimes I need to reboot

An @ sign would be an incorrectly decoded NUL.

But the fact that the output changes worries me more.

If you find any more info, please update this ticket.

And now it's "TELE2" in uppercase:

dongle show device state tele2
...
Provider Name : TELE2

I don't know, how I do this. I just toggle modem power on the usb hub.

And some time after it become Tele2� again.

Looks like it's not the asterisk-chan-dongle bug!

May it be a simcard bug?

[532910]

Another dongle shows the same error, but all my dongles are E1550 with the same firmware.

[532910]

I've replaced the simcard, but nothing changed.
Sometimes it shows
+COPS: (2,"Tele2@","Tele2�","25020",2)...
sometimes it shows
+COPS: (2,"Tele2�","Tele2 ","25020",2)...

Maybe you want to share the make/model of your dongle as well.
