Hi,
I’ve tried to upgrade firmware from R7.44.0 to R7.51.0 but older types of SIM card are not recognized.
New SIM cards works well.
Is there any feature that can enable old SIM cards on new firmware, or we have to replace old SIM cards in our devices?
many thanks
Lukas

Not recognised means?

Hello Luca,
Yes, there´s an issue withe versión R751.I detected this issue with global SIM´s in Q2687RD. Problem is solved with versión R752. Other option is to use a old SIM.
