how can check my lost iphone is on by imei number tell me

Sorry, there is no way to track a lost/stolen phone by IMEI number. Apple provides Find My Phone, but it must be turned on/activated before your phone was lost/stolen. If not, there is no way to track your phone.

Find your serial number quickly
You can activate software without following up and registering it... at least that was the case in the past. The serial number is normally located on the disc case or a box inside the main box. If you did not purchase the disc from Adobe then it is possible you would have dealt with a redemption code, in which case it would have been up to you to keep a record of the serial number, especially if you did not follow up and register the software.

How can I find out the apn number of the battery without having it?

I dont have the battery of my iphone 5 anymore but how can i find out the apn number of the battery? I would like to change it but i need to know the apn number to choose the right battery.

Apple does not provide any user-serviceable parts (other than accessories or sometimes a SIM card tray).
Therefore, there are no legitimate iPhone batteries available for sale anywhere.
Anything you find will either be salvaged, counterfeit, or stolen.

I swapped my iphone from apple store india and my imei of iphone changed and i have lost the box and bill of phone , how can i get my old imei number.

I swapped my iphone from apple store india and my imei of iphone changed and i have lost the box and bill of phone , how can i get my old imei number.

Of course it changed. A phone's IMEI number is unique to each phone. The IMEI number for a phone does not transfer to another phone.
Since your iPhone was exchanged under warranty without having the box and bill for the original purchase, you don't need it now either. The exchange under warranty remains under the warranty for the original purchase.

How can I get a Visa Reference Number on a Spectrum Analyzer?

I have a GPIB Address of 18 on a 8593 EM Spectrum Analyzer. How can I get a VISA reference Number for my VI program

You must have a pretty old version of LabVIEW if you need a session ID instead of just a VISA Resource. If that's the case, you need to first use an VISA Open function in which you specify a resource name of GPIB::18. The open function will return a unique ID that you wire to either VISA Write/Read or a subVI in a driver.

That doesn't mean that you have updates.
Not sure how that app works, - normally means you have a notification for that app - what happen when you go into the app?
If you had update it would be a red number for the app store icon

TS4268 How can I remove an imessage phone number?

How can I remove a mobile phone number from Settings>Messages>Send & Receive?

Deactivate iMessage on both devices.
Sounds like iMessage for your ID was initially activated on her device.
Then sign in with the correct ID on your device and activate iMessage, it should like to your number. If it does, repeat with her ID on her device and confirm everything is as desired.
