Yes, but it is not working for me. I have tried with string and numeric options. ---

You mean auto mode is ok but manual mode is not ok? Can you paste the AT log here? ---

+COPS: (1,“Verizon”,“Verizon”,“311480”,7), This only means it is available, it does not mean registered. I suspect your sim card cannot register verizon. ---

@akn I would try the following. at+cmee=1 at+cereg=1 at+cops=1,2,“311480”,7 This will give you a few responses to work with, specifically if the +CEREG unsolicited response comes back with 3 then you know you have been rejected. I presume since you are trying to attach to Verizon you are using a Verizon SIM? There are very few SIM’s that are able to roam on to Verizon and unless you have Verizon approved your application as well then it is most likely to fail. With regards the different ways to manually select a network, you can use AT+COPS or the QMI API’s but that’s it and both mechanisms are as valid as each other. Regards Matt
