I have activated a Aeris 2G SIM and am trying to use it with a NeoWay M590 board. The AT commands work. However, AT+CREG? keeps giving me 0,0 or 0.2, which according to Neoway M590 documentation means "2:the registration is refused". Anyone else had luck with Neoway based board?
We have checked and verified that there is neither registration nor any attempts of registration for the given ICCID since 31st Aug to date. There is no messaging (network logs) for this ICCID indicating it is trying to communicate with the network..
Can you please provide location of the device to check coverage ? Additionally, can you check the signal strength from the device if possible ?
And also if possible do you have a smart phone in which you can insert the SIM to force registration?
