imei

I'm working on an Android app and am getting null back for the IMEI number when using TelophonyManager . This is happening on several Huawei phones. (All of them are Ascend Y530s). The phones all have sim cards and otherwise seem to be operating normally. I was under the impression that only a broken phone would return null IMEI. Clearly this is not the case.. Questions. What exactly is this IMEI number - i.e where is it stored on the device? And what does it mean when a seemingly fine phone returns its value as null ? EDIT I should mention that the IMEI number is not always null . About half

This question already has an answer here: Finding IMEI number using Objective-C 4 answers I need to get imei on iPhones. I use https://github.com/erica/uidevice-extension/blob/master/UIDevice-IOKitExtensions.m to get IMEI. It works fine on iphone 4, 3GS ... even with ios5. But with iPhone 4S, imei is empty. Does somebody have a solution ? Thank you for your answer If you have backup of that iPhone in iTunes, you need to go to Preferences >> Dvices, and the if you hover the backup you should see not only IMEI number but also Serial number and Mobile number. You can check if that IMEI or Serial

I'd like to have an unique identifier for a cell phone. Since there is not a particular way to find IMEI or IMSI on every mobile, I want to know if there are other ways to find an unique identifier for a cellphone. Can anyone suggest a way? You can use just time in millis if you don't need strong UID. Or you can get UUID implementation from J2SE and port it to J2ME. In this way UUID should be stored in RMS. One of the best way is to build server side and distribute app only via this service. When new user try to download app you can put into manifest and jad any UUID you want and use it in

I have tried the accepted answer of How to get IMEI on iPhone? but I got an empty string. I saw somebody suggested to use CoreTelephony framework, but I am not sure how to use it to obtain the IMEI. Any suggestion on how to use this private API? NOTE: this does not work anymore! Haven't tested on any new iOS. You have to add CoreTelephony.h to your project. Make sure the header has int * _CTServerConnectionCopyMobileEquipmentInfo ( struct CTResult * Status, struct __CTServerConnection * Connection, CFMutableDictionaryRef * Dictionary ); Then you can try this code: #import "CoreTelephony.h"

ESN,MEID和PESN ESN(Electronic Serial Number):电子序列号。在CDMA系统中，是鉴别一个物理硬件设备的唯一标识。也就是说每个手机都用这个唯一的ID来鉴别最忌，就和人的身份证一样。 一个ESN有32bits,也就是32/8 = 4bytes. ESN 用8位的16进制来表示，如0x801EA066.随着CDMA移动设备的增多，ESN已经不够用了所以推出了更多位数的MEID. MEID(Mobile Equipment ID): 手机设备识别码，MEID可以表示为14位的16进制码，如0xA1000002B0BEB2.开头的0xA表示CDMA手机，如果是0x9,就表示多模手机。 PESN（Pesudo ESN）:伪ESN。PESN的推出是为了解决向前兼容的问题，PESN的格式与ESN是完全一样的，唯一的区别是PESN采用0x80开头的。将MEID转为pESN,就可以支持ESN的C网内正常使用。 MEID转化为pESN具体的方法是，56 bits的MEID通过SHA-1 hash算法，挑出后6位，然后在开头加上0x80。pESN并不是唯一的，是可能会重复的，但pESN不会跟ESN重复，因为开头强制加了0x80； 以下是一些现况： 1、一个手机只能有一个ESN或一个MEID。如6800、6900均是ESN码；但6950开始就采用MEID码了。 2

I has developed one j2me mobile application. Now client side want to see the mobile IMEI number. So I don't know how to get it, I have tried this line System.getProperty("com.nokia.IMEI"); but it will come null only. Nokia System.getProperty("phone.imei"); System.getProperty("com.nokia.imei"); System.getProperty("com.nokia.mid.imei"); //especially for S40 devices Note: Requires signed MIDlet. S60 3rd edition device does not requires signing to fetch this info.On Series 40 phones this requires that your MIDlet is signed to either operator or manufacturer domain, and this is only available in
