We are using the Telit ME310G1-W1 modem and are planning to switch to the 4G network registration process. Previously, we used a 2-second delay between each AT+CEREG? query. However, after referring to the Telit 2G/3G/4G Registration Process R3 document, we found that it recommends a 5-second delay.
Additionally, the document suggests a flow where, if AT+CEREG? returns 0,3 or 4, the modem should be put into airplane mode and then reattempt registration.
Would this approach be suitable for our project, or do you recommend a different process?
