I have bought a GX LTE 4G module and have inserted a sim card. But it keeps telling me that there is no sim inserted. It doesn't recognise the sim card but when I insert it into my phone it works fine.
It is a normal mobile sim (data and phone) that is inserted into the module. Do I need an only data sim card? Will this fix my problem?
It is inserted into a Multiplus II GX and is running firmware v2.84
Thank you in advance!
