Anyone could help me? One month ago, I bought one att iot starter kit (gen 2), and I think it was really good, so for project purpose, I bought ten (gen 2), but this time, some problems occur.
Firstly, APN problem, I opened two kits, they both cannot connect to the network successfully, the yellow led keeps flashing, then I used set_wwan_modify_apn to attach it to "m2m.com.attz", the problem is solved, but several minutes later, one of them again cannont connect to the network, the yellow led started flashing again. so if any one could help me.
Another problem is SIM card registration problem, I tried to register SIM card online, but it says "unknown SIM ICCID", then I asked the question online, an officer told me that " you don't need to register the SIM card, cause it has already been activated, you should see your SIM card in ATT Control Center". But these kits are bought by others, so I think if I want to see the SIM card in My Control Center account, I should make some connections between the SIM card and my account. One month ago, when I firstly use this kit, I registered my first SIM card, it can successfully be registered, but this time, I cannot "Add more Sim Card" in my account, the problem is "unknow SIM ICCID", I don't know how to deal with the problem, because I want to monitor the data usage in my ATT Control Center about each SIM Card.
Now I only tried two kits, I am not sure if there will be more problems occur on the following 8 kits, so could I ask if you have some real-time contact method instead of leaving problems here, I will appreciate it very much, cause the time of my project is very tight, if a in-time problem solving method could be provided, it should be much better. But if not, I could completely understand. So thank you very much.
Updating: I think the problem should lie in the SIM card, I checked the WNC mode in iot_monitor, the "IP addr: 0.0.0.0". And I still cannot register the SIM card online. Could you help me.
