问题 After searching everywhere I found there is a way to add eSIM in iPhone using the following API func addPlan(with: CTCellularPlanProvisioningRequest, completionHandler: (CTCellularPlanProvisioningAddPlanResult) -> Void) I don't know why but completion handler not returning the result of CTCellularPlanProvisioningAddPlanResult just printing the following error.

问题 Working on a Android network utility Know Your Android Network I know that we can easily handle the changes in network state by creating our own Broadcast Receiver and check whether n/w switched from WiFi to Mobile data, But is there a way to get notification when "Mobile Data" switches from one network type to the other. Basically I need to know when "mobile data" connection jumps from one network type to the other, Below can be the various network types: NETWORK_TYPE_1xRTT NETWORK_TYPE_CDMA

问题 Is there any way to access NAS messages from LTE network on Android platform? I have all needed software for decoding, but can't get actual message. 回答1: NAS messages are present in Baseband log (modem). So, you have to capture Modem Logs in order to check NAS message (or any other OTA Message). Those messages does not reach the AP (android) side. So, those messages are only present in Modem Logs. Each modem vendor saves modem log in a different format. They also has its own tool to decode

问题 Is there a way to get the iPhone's carrier, and/or the current signal strength, using Objective-C? I know how to determine if a data connection is present, and whether or not that connection is wi-fi vs. cellular. I also know that you can manually place the iPhone into "field test" mode by going to the phone app, and dialing #3001*12345*# and hitting Send. 回答1: You made me curious and I found out that it's actually *3001#12345#* (hashes and stars exchanged). 回答2: This probably won't pass
