Have you tried setting AT+COPS? command? You can set automatic network detection off by sending AT+COPS=1 and then the network name etc. that you want to switch to. You will fidn the numeric or alphanumeric network names or codes when you send an AT+COPS?
Hope this helps
I ran into another issue where it seems that I have to power cycle the device for it to connect to network “B” after it was previously connected to network “A”. I am a bit concerned about what will happen in a real world scenario where signal strength from network “A” has deteriorated and connection to network “ B” is required. Power cycling the device is really not a very good option. Any thoughts, input or suggestions would be greatly appreciated.
I assume you ran into this when using "AT+COPS=1". If so, this is the main reason you don't want to use this command. If you lose the network, the module will not connect to other networks. However, when the module is reset it returns to automatic network selection. DON'T use "AT+COPS=1".
