GSM4 v 7.035

[juwi_uk]

Can you clarify \"some gsm modules\" point; do you mean modules of the different chipset types that have been Introduced over the last few years or within certain modules  of the same chipset type.
My question is because this is posted at a gsm4 firmware but surely this is SIM900 chipset only? Are you saying there are different batches of these?
